Cold Front Arrives Late This Week

Mon, 09/08/2014 - 06:19

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

STILL WARM AND HUMID THROUGH MID-WEEK: Alabama’s weather won’t change very much through Wednesday; warm, humid days with a mix of sun and clouds, and the risk of a few showers and storms each afternoon. The storms should be pretty widely spaced, and afternoon highs will be in the 88-91 degree range, just above average for early September in Alabama (Birmingham’s average high for September 8 is 87 degrees). Humidity levels will remain rather high with a summer feel.

PATTERN CHANGE AHEAD: A deep surface low will form over the Great Plains tomorrow, moving to the Great Lakes Wednesday. This will pull a cold front southward, the leading edge of much cooler air that is now over Canada. A fairly significant severe weather threat is setting up south and east of the surface low on these two days over the northern U.S.

This cold front will push into Alabama Thursday night, and an organized band of showers and storms should push through our state. No severe weather is expected here, as the main surface low and dynamic support will remain to the north. Looks like the main window for showers and storms ahead of the front will come from about 4:00 p.m. Thursday through 4:00 a.m. Friday; rain amounts of around 1/2 inch can be expected.

REFRESHING CHANGE: The sky becomes partly to mostly sunny Friday, with a fresh north breeze and lower humidity, and the weekend ahead will be very nice with ample sunshine Saturday and Sunday, low humidity, and pleasant highs. Looks like the high will be in the low 80s over the weekend, with early morning lows in the 58-62 degree range.

You won’t need jackets or sweaters this weekend, but it will be more comfortable at high school and college football games. No threat of storms, lower humidity levels, and cooler nights.

The dry weather continues into at least the first half of next week; see the Weather Xtreme video for maps, graphics, and details.

TROPICS: The Atlantic basin remains very quiet at a time when the tropics should be peaking. There is a new wave coming off the coast of Africa with some chance of development; it will move west-northwest in coming days in a relatively dry airmass. Remains to be seen if this will develop at all, recurve, or be some threat to land. We will keep an eye on it.

GULF COAST FORECAST: Pretty typical early September weather from Panama City over to Gulf Shores this week; about 6 to 8 hours of sunshine each day with the risk of scattered thunderstorms; highs will be in the upper 80s on the immediate coast, and the sea water temperature this morning at the Dauphin Island Sea Lab is 85 degrees. The cooler and drier air will have a hard time reach the coast this weekend, but showers will become fewer in number, most likely, by Saturday and Sunday.

WEATHER BRAINS: Don’t forget you can listen to our weekly 90 minute netcast anytime on the web, or on iTunes. This is the show all about weather featuring many familiar voices, including our meteorologists here at ABC 33/40. We will produce this week’s show tonight at 8:30 CT… you can watch it on “James Spann 24/7″ on cable systems around the state, or on the web here.

Storms Firing Up

Sun, 09/07/2014 - 14:07

A cold front slipped through the area overnight. That front is located over South Central Alabama this afternoon.

Showers and thunderstorms were blowing up from Hale and Bibb Counties southeastward into the Montgomery area.

Isolated storms were over the northeastern part of Jefferson County.

Some of the storms were quite strong with heavy rain, frequent lightning and gusty winds. They will continue pushing southeastward through the afternoon hours.

Temperatures were in the lower 90s mostly before the storms. The only exceptions across the northern half of the state was in the Northwest corner where readings in the middle 80s were the norm thanks to stubborn early morning clouds.

Another Summer-ish Day

Sun, 09/07/2014 - 07:13

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

We saw a mix of sun, clouds, and scattered showers yesterday, and today should be a lot like that. The weak frontal boundary will continue to wash out and just a slight amount of drying in the atmosphere should reduce our chances for showers as we head into the upcoming work week. But for today look for scattered showers once again with our afternoon highs reaching close to 90.

There is not much change occurring in the upper atmosphere over the next few days. A weak trough passing today will assist with some shower production keeping the showers primarily scattered as moisture settles south of the Birmingham area. Following the moisture, the better chances for scattered showers will move into South Alabama while North and Central Alabama experience just enough of a drop in precipitable water for showers to become isolated, so that most of us stay dry. Morning lows will continue in the 68 to 72 range while afternoon highs will dance with 90 degrees on most days.

While the main westerlies continue to hug the Canadian border for much of the week, there is a strong trough passing well to the north of us at the end of the week which will drag a front toward Alabama by Thursday. Because the main dynamics continue to stay very far north, the front is likely to stall in our vicinity. This could impact our weather for Friday with better chances for showers and storms. While the main dynamics remain well north the GFS and ECMWF seem to be in fairly good agreement on bringing drier and cooler air into our area with a large surface high to our north and northeast. This is verging on voodoo, and I would like to see the upper flow become less zonal to support the idea of the front pushing through our area.

The tropics are ramping up a little. Three areas are being watched, but the newest area just coming off the African continent has the greatest potential for developing into a full blown tropical system in the next five days. In the eastern Pacific, Norbert is weakening as it remains offshore of the Baja Peninsula and is likely to come ashore as a depression in the Wednesday/Thursday time frame.

For beach enthusiasts, it will be warm and humid with a mix of sun and clouds each day. Sunshine should still be fairly good with 4 to 7 hours each day. Rain chances will be a little above average each day with the best chance for rain during the afternoon and into the evening hours. Highs will be in the upper 80s each afternoon while lows will be in the upper 70s. Water temperature this morning at the Dauphin Island Sea Lab was 86 degrees.

As we saw yesterday with the GFS, the pattern is likely to become active in week two with a fairly strong trough developing again over the eastern US around the 16th. And the GFS keeps this idea of the troughiness in place out through the 22nd. This could certainly spell some much cooler days if this verifies correctly.

A Few Strong Storms

Sat, 09/06/2014 - 19:51

A few strong storms are occurring tonight over North Central Alabama ahead of a cool front.

Strong storms are over eastern Winston County, Cullman County near Hanceville and another weaker one between Ashville and Ohatchee in St. Clair County.

They are moving only slowly south southeast.

If you find yourself in the path of one of these storms be ready for torrential rains, deadly lightning and gusty winds.

Midday Radar Check

Sat, 09/06/2014 - 12:16

We continue to be under a very moisture rich air mass across the state today. We are seeing a mix of sun and clouds, with very warm and humid conditions. As the atmosphere heats up, and instability builds, showers and storm begin bubbling up across the state. Looking at the radar, we are seeing scattered to numerous showers across the Alabama landscape.

There are a few storms mixed in with the showers, but overall we are just seeing showers. The general movement of today’s convection is towards the south. A weak frontal boundary is sagging south into the state, and that is also helping provide a little bit of extra uplift which is helping showers develop as well.

Heading through the rest of the afternoon, expect more of the same. A mix of sun and clouds, with showers and storms. Storms should continue into the evening hours before winding down once the daytime heating is lost.

Mix of Sun, Clouds, and Showers

Sat, 09/06/2014 - 06:48

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

Summer continues to roll along with another day forecast to include scattered showers. And Sunday is likely to be a close copy to today. A weak front sagging into Alabama will give us a bit better chance for showers today and again Sunday as the front washes out. Slightly drier air will lower our chances for showers as we head into next week.

By Tuesday and Wednesday, a weak ridge aloft will help to keep us warm with highs in the upper 80s. While moisture will be somewhat limited we’ll still have to include a small chance of showers – in the 20 to 30 percent range – until the end of the week. At the end of the week, a fairly strong trough but traveling across the Great Lakes promises to bring a front into the Southeast US. There are some timing differences between the GFS and the ECMWF with the GFS latest run coming in slightly faster with the front. We’ll have to keep an eye on this timing since it could impact the weather for high school football games next Friday.

FOOTBALL WEATHER: Alabama hosts Florida Atlantic University (FAU) at Bryant-Denny Stadium for an 11:00a kickoff. Expect a mix of sun and clouds with the risk of a passing shower or thunderstorm during the game. The temperature will rise from near 86 at kickoff, to near 92 by the final whistle. Auburn will host San Jose State at Jordan-Hare Stadium this evening (6:00p kickoff)… it will be warm and humid with a kickoff temperature in the mid 80s; the chance of a shower or storm is about one in three, mainly during the first half of the game. Temperatures will fall into the upper 70s by the fourth quarter. UAB is on the road, playing Mississippi State at Davis Wade Stadium in Starkville (2:00p kickoff). Hot and muggy conditions are likely during the game, with a kickoff temperature near 89 degrees. A shower or storm is possible during the game, but the rain won’t be continuous, and the sun will be out at times.

Heading to the beach? Look for 6 to 8 hours of sunshine each day of the weekend with a passing shower possible. Rain chances should run about 30 percent. Highs will be in the upper 80s. Sea water temperature along the Alabama and Northwest Florida coastal area was running in the middle to upper 80s.

Tropics remain relatively quiet considering that we are at the heart of the Atlantic hurricane season. An area of disturbed weather along the Southeast US coast will bring rain to the coastal area but any development of this area will be slow to occur as it drifts slowly northeastward. An elongated area of lower pressure was situated southeast of the Cape Verde Islands, however, dry air over the tropical Atlantic is expected to limit any development of this system.

Looking out into Week 2 or voodoo country, the GFS is painting a long wave trough position over the eastern half of the country. This could include the passage of a front or two during that time frame. Days are getting shorter as we head toward the autumnal equinox on September 22nd.

And you can follow news and weather updates from ABC 33/40 on Twitter here. Stay in the know by following the whole gang – here’s the list…

Humid Air Continues To Hang Over Alabama

Fri, 09/05/2014 - 15:33

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR CHECK: As expected, we have another classic case of random, scattered, slow moving showers and thunderstorms across the great state of Alabama this afternoon. The heavier storms are producing torrential rain, lots of lightning, and gusty winds, and due to light winds aloft there is very little motion. Away from the showers and storms, temperatures are mostly in the mid to upper 80s.

Showers and storms will fade away later tonight once the sun goes down.

THE ALABAMA WEEKEND: No real change tomorrow. Humid air, mixed sun and clouds, and the risk of scattered showers and thunderstorms, most numerous during the afternoon and evening hours. The chance of any one spot getting wet tomorrow will remain in the 30-40 percent range.

The GFS continues to advertise drier air over the northern half of the state Sunday, so from I-20 north the risk of a shower will be small; the bulk of the showers and storms will be over the southern counties of Alabama. Highs over the weekend will be generally in the upper 80s.

FOOTBALL WEATHER: For the high school games tonight… the weather will be warm and humid with kickoff temperatures mostly in the mid to upper 80s. A shower or storm will be possible during the first half at a few stadiums; the specific risk of rain for any one given field is about 30 percent.

Alabama hosts Florida Atlantic University (FAU) at Bryant-Denny Stadium tomorrow (11:00a kickoff)… expect a mix of sun and clouds with the risk of a passing shower or thunderstorm during the game. The temperature will rise from near 85 at kickoff, to near 88 by the final whistle.

Auburn will host San Jose State at Jordan-Hare Stadium tomorrow evening (6:00p kickoff)… it will be warm and humid with a kickoff temperature in the mid 80s; the chance of a shower or storm is about one in three, mainly during the first half of the game. Temperatures will fall into the upper 70s by the fourth quarter.

UAB is on the road, playing Mississippi State at Davis Wade Stadium in Starkville (2:00p kickoff). Hot and muggy conditions are likely during the game, with a kickoff temperature near 89 degrees. A shower or storm is possible during the game, but the rain won’t be continuous, and the sun will be out at times.

NEXT WEEK: Widely scattered showers and thunderstorms are possible Monday through Wednesday, then we expect an organized band of showers and storms late Thursday and Thursday night. And, on Friday, a much cooler and drier airmass will drop in here from the north thanks to a deep upper trough that is expected to form over the eastern third of North America. Some of the colder pockets across North Alabama could see lows in the upper 40s by Saturday September 13. See the Weather Xtreme video for maps, graphics, and more details.

GULF COAST WEATHER: About 6 to 8 hours of sunshine each day through early next week with the daily chance of scattered showers and thunderstorms. Highs will be in the upper 80s, and sea water temperatures are mostly in the mid 80s.

TROPICS: A disturbance near the Cape Verde Islands in the far East Atlantic could show some slow development over the weekend, but it expected to gain latitude, and it does not look like a system that will be an issue for the Gulf of Mexico. The rest of the Atlantic basin is quiet. Over in the East Pacific, Hurricane Norbert will move northwest parallel to the coast of Baja California this weekend, weakening as it encounters colder water. But, moisture from Norbert will move up into the Southwest U.S. late in the weekend with heavy rain possible for parts of Arizona and New Mexico.

Sun and Storms; Very Humid

Fri, 09/05/2014 - 06:14

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

UNDER A BIG WET BLANKET: Not much overall change in our weather through tomorrow as a muggy airmass remains parked over the state with dew points in the 70s. We project a mix of sun and clouds today and tomorrow with the continued risk of scattered, slow moving showers and thunderstorms. While they will be most numerous during the afternoon and evening hours, we can’t totally rule out a late night or morning shower. The chance of any one spot seeing a shower or storm remains in the 30-40 percent range, and highs will be in the upper 80s.

Drier air will slip into the northern third of Alabama Sunday, so showers north of Birmingham will be relatively hard to find, but we will maintain the risk of scattered showers and storms along and south of I-20. The high will remain in the upper 80s Sunday afternoon.

FOOTBALL WEATHER: For the high school games tonight… the weather will be warm and humid with kickoff temperatures mostly in the mid to upper 80s. A shower or storm will be possible during the first half at a few stadiums; the specific risk of rain for any one given field is about 30 percent.

Alabama hosts Florida Atlantic University (FAU) at Bryant-Denny Stadium tomorrow (11:00a kickoff)… expect a mix of sun and clouds with the risk of a passing shower or thunderstorm during the game. The temperature will rise from near 85 at kickoff, to near 88 by the final whistle.

Auburn will host San Jose State at Jordan-Hare Stadium tomorrow evening (6:00p kickoff)… it will be warm and humid with a kickoff temperature in the mid 80s; the chance of a shower or storm is about one in three, mainly during the first half of the game. Temperatures will fall into the upper 70s by the fourth quarter.

UAB is on the road, playing Mississippi State at Davis Wade Stadium in Starkville (2:00p kickoff). Hot and muggy conditions are likely during the game, with a kickoff temperature near 89 degrees. A shower or storm is possible during the game, but the rain won’t be continuous, and the sun will be out at times.

NEXT WEEK: Looks like showers and storms will be widely scattered Monday through Wednesday, but a pattern change will push a cold front through here later in the week Thursday night; ahead of the front a band of showers and thunderstorms is likely. Then, cooler and drier air will push into the state at the end of the week on Friday, making it feel like fall. A good chance we drop into the 50s early Saturday morning (September 13). See the Weather Xtreme video for maps, graphics, and more details.

TROPICS: A tropical wave near the Cape Verde Islands will move west/northwest in coming days with some slow development possible. If anything happens to form here, more than likely it will gain latitude and recurve before impacting the U.S. But, it is too early to call. And, over in the East Pacific, Hurricane Norbert is near the southern tip of Baja California; it will weaken and dissipate early next week, but moisture from the system will move up into the Southwest U.S. with potential for some flooding over parts of Arizona and New Mexico by Monday and Tuesday.

AT THE BEACH: About 6 to 8 hours of sunshine along the coast from Panama City over to Gulf Shores through early next week, with scattered storms possible each day. Highs will be mostly in the upper 80s, with sea water temperatures generally in the mid 80s.

Scattered Showers/Storms Stay In The Forecast

Thu, 09/04/2014 - 15:37

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR CHECK: Scattered, nearly stationary thunderstorms are over Alabama this afternoon in random places; they are producing very heavy rain and lightning…

These will fade away late tonight…. otherwise today is partly sunny with temperatures mostly in the upper 80s at mid-afternoon.

TOMORROW/SATURDAY: Not much change. A blanket of very moist air remains over the state, and we project a mix of sun and clouds both days with the risk of scattered showers and thunderstorms. The best chance of a passing storm will come during the afternoon and evening hours, but a late night or morning shower can’t be totally ruled out. Afternoon highs will be generally in the upper 80s, right at seasonal levels for early September in Alabama.

SUNDAY: The GFS continue to bring down drier air into North Alabama temporarily Sunday, and it looks like the best chance of scattered storms will come over the southern half of the state. The chance of a shower over North Alabama Sunday afternoon is not zero, but many communities from Birmingham north will be dry. Sunday’s high will be in the upper 80s.

FOOTBALL WEATHER: For the high school games tonight and tomorrow night… the weather will be warm and humid with kickoff temperatures mostly in the mid to upper 80s. A shower or storm will be possible during the first half at a few stadiums; the specific risk of rain for any one given field is about 30 percent.

Alabama hosts Florida Atlantic University (FAU) at Bryant-Denny Stadium Saturday (11:00a kickoff)… expect a mix of sun and clouds with the risk of a passing shower or thunderstorm during the game. The temperature will rise from near 85 at kickoff, to near 88 by the final whistle.

Auburn will host San Jose State at Jordan-Hare Stadium Saturday evening (6:00p kickoff)… it will be warm and humid with a kickoff temperature in the mid 80s; the chance of a shower or storm is about one in three, mainly during the first half of the game. Temperatures will fall into the upper 70s by the fourth quarter.

UAB is on the road, playing Mississippi State at Davis Wade Stadium in Starkville (2:00p kickoff). Hot and muggy conditions are likely during the game, with a kickoff temperature near 89 degrees. A shower or storm is possible during the game, but the rain won’t be continuous, and the sun will be out at times.

NEXT WEEK: A few scattered showers and storms are possible each day during the first half of the week, but global models are showing a pattern change by the end of the week… a full latitude upper trough is forecast to form over the eastern part of North America, and this should bring down cooler, drier air into Alabama by Friday and the following weekend (September 12-14). See the Weather Xtreme video for maps, graphics, and details.

TROPICS: A disturbance has emerged off the coast of Africa, designated “Invest 90L”. This could show some slow development over the weekend ahead, but it will be gaining latitude and is not expected to impact the U.S. one way or another at this point.

GULF COAST: About 6 to 8 hours of sunshine each day on the coast from Panama City over to Gulf Shores through the weekend with the daily chance of scattered thunderstorms. Highs on the immediate coast will be in the upper 80s, and sea water temperatures are mostly in the mid 80s.

Muggy Air Hangs Over Alabama

Thu, 09/04/2014 - 06:11

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR CHECK: All is quiet across Alabama this morning… nothing on radar, but there is some patchy fog, especially where showers and storms formed yesterday afternoon.

The overall pattern isn’t much different today with moist air over the state and a weak upper low near Mobile. We do note precipitable water values are down a bit; they were around 2.1″ yesterday over North/Central Alabama, but this morning they are near 1.9″. Still sufficient for scattered showers and storms this afternoon and this evening, but the coverage will most likely be lower than what we saw yesterday. Highs today will be in the upper 80s in most places.

TOMORROW AND THE WEEKEND: Pretty much the same story tomorrow and Saturday… very humid with a mix of sun and clouds both days along with scattered showers and thunderstorms, most numerous during the afternoon and evening hours. Impossible to tell you exactly when and where the showers will form, but if you have something planned outdoors, just be ready for rain at times. The afternoon high will remain in the 87-90 degree range.

The GFS is back on the idea of drier air working down into Alabama from the north Sunday, hinting that most of the showers and storms Sunday afternoon will come over the southern half of the state. Not quite ready to buy into that due to model inconsistency; we will still mention the chance of a passing shower or storm Sunday afternoon for now. The high will be generally in the upper 80s.

FOOTBALL WEATHER: For the high school games tonight and tomorrow night… the weather will be warm and humid with kickoff temperatures mostly in the mid to upper 80s. A shower or storm will be possible during the first half at a few stadiums; the specific risk of rain for any one given field is about 30 percent.

Alabama hosts Florida Atlantic University (FAU) at Bryant-Denny Stadium Saturday (11:00a kickoff)… expect a mix of sun and clouds with the risk of a passing shower or thunderstorm during the game. The temperature will rise from near 85 at kickoff, to near 89 by the final whistle.

Auburn will host San Jose State at Jordan-Hare Stadium Saturday evening (6:00p kickoff)… it will be warm and humid with a kickoff temperature in the mid 80s; the chance of a shower or storm is about one in three, mainly during the first half of the game. Temperatures will fall into the upper 70s by the fourth quarter.

UAB is on the road, playing Mississippi State at Davis Wade Stadium in Starkville (2:00p kickoff). Hot and muggy conditions are likely during the game, with a kickoff temperature near 90 degrees. A shower or storm is possible during the game, but the rain won’t be continuous, and the sun will be out at times.

NEXT WEEK: We will keep the chance of “scattered, mostly afternoon and evening showers and thunderstorms” going for at least the first half of next week; see the Weather Xtreme video for maps, graphics, and more details.

TROPICS: A tropical wave is coming off the coast of Africa, some chance of slow development this weekend, but very dry air will surround the system as it moves west/northwest. The rest of the Atlantic basin is very quiet.

AT THE BEACH: About 6 to 8 hours of sunshine each day along the coast from Panama City over to Gulf Shores with scattered storms possible. Highs in the upper 80s on the immediate coast… the sea water temperature early this morning at the Dauphin Island Sea Lab is 86 degrees.

Hit and Miss Showers And Storms

Wed, 09/03/2014 - 15:09

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR UPDATE: A classic case of “scattered afternoon showers and thunderstorms” on a late summer day in Alabama. Some of the heavier storms at mid-afternoon are east of I-65, and they are moving slowly to the east. Heavier storms are producing lots of lighting, very heavy rain, and gusty winds. They will calm down late tonight as the air becomes more stable.

TOMORROW THROUGH SUNDAY: It will be very hard to discern day to day weather changes; the overall pattern just won’t be changing much. Moist, unstable air stays in place, and we will have the daily risk of scattered showers and thunderstorms. While they are most likely during the afternoon and evening hours (when the air is most unstable), we can’t totally rule out a late night or morning shower. During the daytime hours will have a mix of sun and clouds, and afternoon highs will be mostly in the 87 to 90 degree range. The chance of any one spot getting wet each day will remain in the 30-40 percent category. Very typical weather for early September in Alabama.

FOOTBALL WEATHER: For the high school games tomorrow and Friday evening… the weather will be warm and humid with kickoff temperatures mostly in the mid to upper 80s. A shower or storm will be possible during the first half at a few stadiums; the specific risk of rain for any one given field is about 30 percent.

Alabama hosts Florida Atlantic University (FAU) at Bryant-Denny Stadium Saturday (11:00a kickoff)… expect a mix of sun and clouds with the risk of a passing shower or thunderstorm during the game. The temperature will rise from near 85 at kickoff, to near 90 by the final whistle.

Auburn will host San Jose State at Jordan-Hare Stadium Saturday evening (6:00p kickoff)… it will be warm and humid with a kickoff temperature in the mid to upper 80s; the chance of a shower or storm is about one in three, mainly during the first half of the game. Temperatures will fall into the upper 70s by the fourth quarter.

UAB is on the road, playing Mississippi State at Davis Wade Stadium in Starkville (2:00p kickoff). Hot and muggy conditions are likely during the game, with a kickoff temperature near 90 degrees. A shower or storm is possible during the game, but the rain won’t be continuous, and the sun will be out at times.

NEXT WEEK: The GFS continues to suggest the air will be a little drier across the great state of Alabama next week, meaning showers and storms will be fewer in number and more widely spaced. See the Weather Xtreme video for the maps, graphics, and more details.

TROPICS: Tropical Storm Dolly is dissipating over Mexico this afternoon, and the Atlantic basin is now very quiet for the first week of September, a time when tropical activity tends to be peaking.

GULF COAST WEATHER: About 6 to 8 hours of sunshine each day along the coast from Panama City over to Gulf Shores through the weekend with a few scattered storms around each day. Highs 87-90; sea water temperatures remain mostly in the mid 80s.

RADAR CHECK: We have a few showers over parts of North Alabama at daybreak; some moderate rain was falling over Marion County at 6:00 a.m. These showers are moving east, and a sign a very moist airmass remains over Alabama. Precipitable water values are in excess of two inches over much of North/Central Alabama earl this morning…

Scattered showers and storms should become more numerous this afternoon as the air becomes more unstable; otherwise expect a mix of sun and clouds today with a high between 87 and 90 degrees.

REST OF THE WEEK: Not much change as the muggy air hangs over Alabama. Sun at times; scattered showers and storms tomorrow and Friday. Highs 87 to 90 degrees.

THE ALABAMA WEEKEND: Nothing to suggest any drier air moves in here, so the weather just won’t change much. The sun will be out at times Saturday and Sunday, and we will dodge scattered showers and thunderstorms both days. Highs will hang in that 87 to 90 degree range.

FOOTBALL WEATHER: For the high school games tomorrow and Friday evening… the weather will be warm and humid with kickoff temperatures mostly in the mid to upper 80s. A shower or storm will be possible during the first half at a few stadiums; the specific risk of rain for any one given field is about 30 percent.

Alabama hosts Florida Atlantic University (FAU) at Bryant-Denny Stadium Saturday (11:00a kickoff)… expect a mix of sun and clouds with the risk of a passing shower or thunderstorm during the game. The temperature will rise from near 85 at kickoff, to near 90 by the final whistle.

Auburn will host San Jose State at Jordan-Hare Stadium Saturday evening (6:00p kickoff)… it will be warm and humid with a kickoff temperature in the mid to upper 80s; the chance of a shower or storm is about one in three, mainly during the first half of the game. Temperatures will fall into the upper 70s by the fourth quarter.

UAB is on the road, playing Mississippi State at Davis Wade Stadium in Starkville (2:00p kickoff). Hot and muggy conditions are likely during the game, with a kickoff temperature near 90 degrees. A shower or storm is possible during the game, but the rain won’t be continuous, and the sun will be out at times.

NEXT WEEK: The GFS hints moisture levels will be down slightly, but we will still need to mention some risk of scattered showers and storms each day with highs in the mid to upper 80s. Sure looks like the days with consistent highs in the 90s are behind us… see the Weather Xtreme video for maps, graphics, and more details.

TROPICS: Tropical Storm Dolly moved into the coast of Mexico well south of Brownsville, TX last night… otherwise the Atlantic basin is unusually quiet for early September.

Hot, Humid, Scattered Storms

Tue, 09/02/2014 - 15:33

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR CHECK: So far today the majority of the showers and storms have been over the western half of Alabama; they are random, scattered, and not moving much. Otherwise, it is a partly sunny day with temperatures mostly in the low 90s at mid-afternoon. The showers and storms will fade away this evening once the sun goes down.

REST OF THE WEEK: No real change in the weather; the primary jet stream will remain north of Alabama, and our weather will be pretty typical of early September. Partly sunny days with the risk of “scattered, mostly afternoon and evening showers and thunderstorms”. The chance of any one spot getting wet each afternoon is about one in three… the showers and storms will form in random places and probably won’t move very much.

THE ALABAMA WEEKEND: Still no sign of any serious weather change. Mixed sun and clouds Saturday and Sunday with the risk of scattered showers and thunderstorms, mostly during the afternoon and evening hours. Afternoon highs will be close to 90 degrees.

FOOTBALL WEATHER: For the high school games Thursday and Friday evening… the weather will be very warm and humid with kickoff temperatures mostly in the mid to upper 80s. A shower or storm will be possible during the first half at a few stadiums; the specific risk of rain for any one given field is about 30 percent.

Alabama hosts Florida Atlantic University (FAU) at Bryant-Denny Stadium Saturday (11:00a kickoff)… expect a mix of sun and clouds with the risk of a passing shower or thunderstorm during the game. The temperature will rise from near 85 at kickoff, to near 90 by the final whistle.

Auburn will host San Jose State at Jordan-Hare Stadium Saturday evening (6:00p kickoff)… it will be warm and humid with a kickoff temperature in the mid to upper 80s; the chance of a shower or storm is about one in three, mainly during the first half of the game. Temperatures will fall into the upper 70s by the fourth quarter.

UAB is on the road, playing Mississippi State at Davis Wade Stadium in Starkville (2:00p kickoff). Hot and muggy conditions are likely during the game, with a kickoff temperature near 90 degrees. A shower or storm is possible during the game, but the rain won’t be continuous, and the sun will be out at times.

NEXT WEEK: Heat levels come down a bit with highs mostly in the 80s, but no sign of any serious cool down. See the Weather Xtreme video for the maps, graphics, and details.

TROPICS: Tropical Storm Dolly, in the far Southwest Gulf of Mexico, is packing sustained winds of 50 mph, and will move into the coast of Mexico, well south of Brownsville, Texas, late tonight after midnight. The rest of the Atlantic basin is very quiet.

Scattered Afternoon Storms

Tue, 09/02/2014 - 06:05

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

DOESN’T FEEL LIKE FALL: We all know it can be very hot in Alabama in early September. In fact, our hottest temperature on record was recorded on September 5, 1925, when the high in Centreville (Bibb County) was 112 degrees. Nothing like that this week, but we do project highs in the low 90s each afternoon through Friday.

Each day will feature a mix of sun and clouds, and each afternoon we expect developing showers and thunderstorms in scattered and random locations. The chance of any one spot getting wet each day through Friday is about one in three, and the best chance of seeing a shower or storm will come from about 2:00 until 8:00 p.m. A very typical late summer weather pattern.

THE ALABAMA WEEKEND: The primary “jet stream” over North America will stay well to the north of Alabama, and the weather probably won’t be changing very much. We will forecast a partly sunny sky Saturday and Sunday, and we will also maintain the risk of “scattered, mostly afternoon and evening showers and thunderstorms”. Both Alabama and Auburn have in state football games Saturday; the chance of a shower or storm at both sites is about 30 percent. We will have a much more specific kickoff forecast tomorrow.

A front north of the state according to the latest model data won’t get south of I-40 in Tennessee, so no dry air is expected to reach our state.

NEXT WEEK: Heat levels should be a bit lower next week with highs dropping into the upper 80s; no sign of the first good cold front of the fall season, however. See the Weather Xtreme video for the maps, graphics, and more details.

TROPICS: Tropical Storm Dolly has formed over the Bay of Campeche with top winds of 45 mph; it will move into the coast of Mexico well south of Brownsville, Texas after midnight tonight. The rest of the Atlantic basin is amazingly quiet for early September.

WEATHER BRAINS: Don’t forget you can listen to our weekly 90 minute netcast anytime on the web, or on iTunes.

Five Forms

Mon, 09/01/2014 - 16:14

Air Force reconnaissance found a well defined circulation is the Bay of Campeche about 250 miles from the Mexican Gulf Coast.

The storm is moving WNW at 13 mph and will move inland in Mexico tomorrow evening.

Top winds are 30 mph and the plane recently found a central pressure of 1008 mb.

The water is warm but wind shear is strong and Five will only slowly strengthen. It should become Tropical Storm Dolly tomorrow afternoon before landfall.

A Few Scattered Storms Around

Mon, 09/01/2014 - 15:22

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

RADAR CHECK: Widely scattered showers and storms have fired up across parts of Alabama this Labor Day afternoon. Most of them at mid-afternoon were south of I-20, and east of I-65… they are moving northeast, and will fade away once the sun goes down later this evening. Temperatures are generally in the 90-93 degree range.

REST OF THE WEEK: The weather just won’t change very much through Friday. Partly sunny days, and the daily risk of the hit and miss, “scattered, mostly afternoon and evening showers and thunderstorms”. Storms in an environment like this form in random places, and come and go pretty quickly. But, they can be strong and produce brief heavy rain in a few places. Afternoons highs will be somewhere between 91 and 94 degrees in most communities.

THE ALABAMA WEEKEND: The ridge weakens a bit, and a surface front will ease down into Tennessee Saturday. This could give us a little bump in the number of thunderstorms Saturday and Saturday night, but it still won’t rain everywhere, and the day Saturday will feature a mix of sun and clouds with a high around 90 degrees.

There is a chance drier air could temporarily drop into far North Alabama Sunday, but the front will probably fizzle out near the Tennessee Valley, and we will continue to mention at least a chance of a pop up shower or storm Sunday afternoon; the high will stay close to 90 degrees.

NEXT WEEK: Heat levels should back off a bit as the ridge weakens; looks like highs in the mid to upper 80s. See the Weather Xtreme video for maps, graphics, and more details.

TROPICS: A disturbance in the Bay of Campeche has a decent chance of becoming a tropical depression or storm over the next 36 hours, but it will move into the Mexican coast far south of Brownsville, Texas Wednesday. The rest of the Atlantic basin is very quiet. In fact, there is not a single tropical cyclone on the planet this afternoon, a very rare thing for September 1.

GULF COAST WEATHER: About 6 to 8 hours of sunshine from Panama City to Gulf Shores through Friday with a few scattered storms around daily; highs on the immediate coast will be in the 87 to 90 degree range. The sea water temperature this afternoon at the Dauphin Island Sea Lab is 85 degrees.

WEATHER BRAINS: Don’t forget you can listen to our weekly 90 minute netcast anytime on the web, or on iTunes. This is the show all about weather featuring many familiar voices, including our meteorologists here at ABC 33/40. We will produce this week’s show tomorrow night at 8:30 CT.

Meteorological Fall Begins

Mon, 09/01/2014 - 06:30

**No Weather Xtreme video this morning… I will produce one this afternoon before 4:00**

STILL LIKE SUMMER: The calendar says today is the first of September, but the weather will still be like August this week thanks to an upper ridge across the Deep South. We project a high in the low to mid 90s today and tomorrow with ample sunshine and only widely scattered afternoon showers or storms.

LATER THIS WEEK: The upper ridge will break down a bit, allowing an increase in the number of afternoon showers and thunderstorms Wednesday through Friday; the chance of any one spot seeing an afternoon shower or storm on these three days is about one in three with a high in the low 90s.

WEEKEND FORECAST: Not much change; a typical late summer pattern continues with a few scattered, mostly afternoon and evening showers and thunderstorms possible Saturday and Sunday with a high at or just over 90 degrees. The primary storm track remains to the north of Alabama, and cooler air isn’t allowed to drop this far south.

LONG RANGE: Model data suggests temperatures will fall next week, with highs in the 80s and lows in the 60s, making it feel more like September…

GULF COAST WEATHER: About 6 to 8 hours of sunshine each day this week along the coast from Panama City to Gulf Shores with just a few widely scattered storms; highs in the 87-91 degree range on the immediate coast, with sea water temperatures mostly in the mid 80s.

TROPICS: The Atlantic basin is very quiet; the only system to discuss is over the Yucatan Peninsula of Mexico… this has some chance of becoming a tropical storm over the next 48 hours, but it will move west into the Mexican coast, south of Brownsville, Texas at mid-week and is no threat to the U.S.

WEATHER BRAINS: Don’t forget you can listen to our weekly 90 minute netcast anytime on the web, or on iTunes. This is the show all about weather featuring many familiar voices, including our meteorologists here at ABC 33/40. We will produce this week’s show tomorrow night due to the Labor Day holiday.

Settling Back into a Summer-like Pattern

Sun, 08/31/2014 - 06:59

An all new edition of the ABC 33/40 Weather Xtreme video is available in the player on the right sidebar of the blog. You can subscribe to the Weather Xtreme video on iTunes by clicking here.

After a wet start to the Labor Day weekend, showers should be less numerous across Alabama with the better chances for seeing an isolated storm across the northern third of Alabama generally Birmingham and northward. Some patchy fog was occurring thanks to the widespread rain yesterday, but it should burn off by 9 am or so. The sky will contain a mixture of sun and clouds as we see highs climb mainly into the lower 90s. The upper air disturbance that moved out of the Northwest Gulf yesterday and produced a good rainfall event for a sizable chunk of the state especially the western half was moving into the Ohio River Valley today where a number of flash flood watches were posted for heavy rain.

As this disturbance pulls northeastward, the upper ridge will build into and across the Southeast US for the next week pretty much settling us back into a summer-like pattern with daily shower and storm chances thanks to daily heating. As the upper ridge remains the main feature, high temperatures should reach into the lower and middle 90s, generally the 92 to 95 range, for most of the week.

Good looking forecast for the beaches of Alabama and Northwest Florida. While there will be some passing storms possible each day, there will still be plenty of sunshine. Highs at the beach will be near 90, with morning lows near 80. For the week ahead, the weather looks fairly typical along the northern Gulf Coast for the first week in September. Water temperature at Perdido Pass was 85.9 degrees.

Tropics are generally quiet with just one area of disturbed weather moving westward across the Yucatan Peninsula. Conditions are expected to be favorable for strengthening of this system on Monday and Tuesday as it moves out of Yucatan and into the Southwest Gulf of Mexico. The upper ridge across the Southeast US should keep it moving westward into Mexico.

Looking out into voodoo country, the ridge remains the big player for the Southeast US into Week 2, but the GFS is still setting the stage for a substantial rain event around the 12th and 13th of September with a strong trough moving across the Central US that could bring a cold front to the Southeast US.

Storms Over Alabama

Sat, 08/30/2014 - 16:46

We continue to see widespread convection this afternoon. The last few hours, the bulk of the activity has been over western portions of the state, as the storms became somewhat linear. Storms today are producing quite a bit of lightning, gusty winds, and torrential rainfall. The general motion continues to be towards the north.

Over the next several hours, storms will persist as they lift north. The more intense storms at this time are affecting Winston, Walker, Fayette, Bibb, and Chilton counties. Storms should be approaching the Birmingham Metro during the next hour or so. Where it is raining, we are seeing much cooler temps down in the 70s, but where it is not, still 90s.
