Early Morning Update

Mon, 04/14/2014 - 03:32

We are watching a line of strong storms moving across northern Mississippi this morning. There are currently no severe storms with this line of activity but these cells are just below severe limits. There are producing very heavy rainfall, gusty winds, small hail, and frequent and dangerous lightning. This activity will continue to race off to the east and will be impacting Alabama later this morning. The good news is the storms appear to be slowly weakening as they approach the state.

Showers and some rumbles of thunder are already moving into our northwestern counties, but the more intense line of activity will be entering Alabama after 4 AM. It will continue to move across the state during the morning hours. Behind this initial activity we will have to be on guard later today. If the sunshine pops back out and allows the atmosphere to become unstable, we could see a threat of severe weather later today across the state as the actual cold front moves into the state. The latest day one convective outlook from the SPC for Monday has much of Alabama, as well as Mississippi and Louisiana outlined in a slight risk for severe weather.

If we do see the atmosphere recover today from this morning’s activity, we will likely see showers and storms develop mid to late afternoon as the cold front moves into the state. The main threat with the storms that develop will be damaging straight-line winds. With thunderstorms, it is always wise to expect the unexpected and the chance for hail and a tornado or two cannot be ruled out. We will also have to monitor the threat of flash flooding. Much of Central Alabama has been placed under a flash flood watch which will go into effect at 7AM this morning. Remember to TURN AROUND, DON’T DROWN if you encounter flood waters.

Late Night Update

Mon, 04/14/2014 - 00:13

Two lines of showers and storms continue early this morning.

The first extends over western Tennessee and northern Mississippi into northern Lousiana.

The second extends across southeastern Missouri, across Central Arkansas and into northern Louisiana.

All of this activity will push across northern Mississippi overnight.  It should weaken as it does.
There are only five severe thunderstorm warnings still in effect and no tornado warnings.  Severe thunderstorm watches extend from northeastern Texas across much of Arkansas to western Tennessee.

The first round of showers/storms will enter the area around sunrise and continue to impact the area through the mornings hours.  Showers and storms will build again to our west by Afternoon and some of them may become severe Monday afternoon and evening.

Please check the latest information this morning and review your severe weather safety plans.

We will monitor the situation all night.  Expect the next update around 3 a.m. , unless conditions warrant an earlier notification.

Watching to the West

Sun, 04/13/2014 - 21:05

It is an active night of severe weather in areas to the west of Alabama as a dynamic storm system continues to come together.

As we have been advertising, it is a two prong system. The first upper disturbance is moving into Arkansas from Oklahoma tonight, weakening as it goes. Showers and storms extend from southwestern Illinois to southeastern Missouri to Central Arkansas. Further south, new development is building over Central Louisiana.

Flash flood warnings are in effect around Little Rock, where water rescues are going on at this hour from West Little Rock into downtown.

A stronger, intensifying disturbance is moving out of the Rockies tonight. This disturbance is opening the door for a big Arctic airmass to come south. That impressive boundary extends from Chicago to Des Moines to Kansas City to Oklahoma City to Amarillo.

It is 68F at Springfield MO while just a short distance on the other side of the boundary, it is 39F in Salina and 32F in Hill City KS. Just yesterday, Salina was setting a record high with 91F. In Texas, it is 81F at Wichita Falls and 51F at Pampa in the Panhandle. Further back in the cold air it is 24F in Denver with heavy snow.

The main squall line extends from Central Missouri west of St. Louis into northwestern Arkansas across southeastern Oklahoma to the Red River between Texas and Oklahoma. Severe thunderstorm warnings extend from Central Missouri into western Arkansas. A tornado warning was in efect for areas near Ardmore OK a little earlier.

There have been only three tornado reports today, including two from Iowa and one from Oklahoma.

The initial activity will push across northern Mississippi this evening and reach Northwest Alabama before sunrise. The system will be weakening as it pushes through West Alabama, reaching I-59 on mid-morning.

Meanwhile, activity should intensify over northern Louisiana, northern Mississippi and western Tennessee during the day ahead of the main trough and powerful cold front. This activity should reach Northwest Alabama by late afternoon and push through western Alabama between 6-8 p.m. and into the I-59 corridor between 7-9 p.m. It will reach eastern Alabama during the late evening. Showers and storms will continue until the cold front moves through during the predawn hours Tuesday morning.

There is a chance that instabilities will be pretty impressive over western Alabama late tomorrow afternoon. In addition, wind shear values will be high as well, In fact, 0-1 km helicities may be in the 250-300 m2/s2 range. Surface temperatures will push into the middle 70s and dewpoints should be in the middle 60s.

So, we will be monitoring the severe weather potential across Central Alabama through early Tuesday. Indications are that the threat tonight is very low. But we will keep an idea on it. The main threat should come late tomorrow afternoon through tomorrow evening. Hail and damaging winds will be possible and we can’t rule out the threat of tornadoes as well. Stay tuned.

In addition to the severe weather threat, there is a flash flooding threat. Rainfalls across Central Alabama will average 1.5-2.5 inches through Tuesday morning. Flash flood watches are in effect through Tuesday afternoon.

Jackson NWS Adds to Flash Flood Watches

Sun, 04/13/2014 - 15:18

As Bill noted below, the NWS in Birmingham has issued a flash flood watch in effect from Monday morning (7:00 am CDT) through Tuesday midday (1:00 pm CDT) for all of Central Alabama. Just a short time ago, the NWS in Jackson, MS, has added their own flash flood watch which extends further west into Central Mississippi as you can see from the map below.

Besides the severe weather threat, the threat of heavy rain could produce two problems for us. The first is rapid flooding due to the heavy rain. The second is resulting rise in streams and creeks and rivers from what could be a widespread 1 to 3 inch rain total for the storm.

Be sure to stay up with the latest weather information by bookmarking the Alabama Weather Blog.

A Nice Sunday, Severe Weather in the Offing Though

Sun, 04/13/2014 - 12:31

A pleasant spring Sunday is in progress with partly cloudy to occasionally mostly cloudy skies at time. High clouds are starting to stream across the area, and thickening and lowering clouds are to the west. Back over Mississippi, we see a healthy field of cumulus clouds in a plume of moisture surging up into the Magnolia State. By the time you get to the Mississippi River, a thick overcast is in place.

The nearest rain to Alabama is some rain over northwestern Arkansas and some showers over eastern Texas. Thunderstorms are in progress in the Dallas/Ft. Worth area, but they are not strong nor severe at this time.

Temperatures are in the upper generally at this hour. Birmingham and Anniston are at 78F and 77F respectively, Tuscaloosa checked in with 73F at noon, a little cooler since skies are already cloudy. It has become quite breezy, with southerly winds averaging 10-20 mph and gusts to near 30 mph at times.

A quick check of the weather early this afternoon shows that the forecast is on track for Central Alabama.

Severe weather is expected today and tonight to the west of Alabama. There is a large slight risk severe weather outlook area in effect today and tonight in an area roughly bounded by Austin, Wichita Falls, Oklahoma City, Wichita, Kansas City, Peoria, St. Louis, Memphis, Meridian, Alexandria and back to Austin. The moderate risk area that was included in the forecast earlier has been removed due to the clouds and precipitation over Texas and Oklahoma that is reducing instability.

The storms to our west will move eastward overnight, weakening as they move across Mississippi. They should make it into Alabama well after midnight.

As a second surface low develops to our west early tomorrow and instability rises with some daytime heating, storms should ramp up during the day. They should be enough instability and shear in place for some of the storms to become strong to severe by afternoon. It now appears that all modes of severe weather are possible, with hail, damaging winds and even tornadoes. We will be able to refine the exact threat as we move into the daylight hours tomorrow, but for now, review your severe weather safety plans and check your sources for receiving watches and warnings.

Much colder weather is in the offing for Tuesday behind the cold front. Highs will remain in the 50s all day with the threat of some frost Tuesday night as the mercury drops into the middle 30s generally with a few spots reaching freezing. Growers and planters should be aware of the threat and plan accordingly.

Active Weather Tomorrow

Sun, 04/13/2014 - 06:50

A few important notes concerning weather in the days ahead. Today will be warm and dry with a high in the low 80s, but some big changes are ahead.

RAIN/STORMS TOMORROW: SPC has most of Alabama in the standard “slight risk” of severe weather tomorrow, with an enhanced 30% chance over the central counties…

Defining the severe weather threat tomorrow is somewhat complicated. A large mass of rain is expected to move across Alabama after midnight tonight into tomorrow morning, and this will limit the amount of instability available for the “second round” later in the day. If clouds hold in place through the day, the rain cooled air will greatly limit the severe weather potential over the northern half of Alabama. The wind fields will support some risk of severe weather; we will just have to watch developments closely during the day.

I would suggest the primary threats will come from strong straight line winds and hail, although an isolated tornado can’t be ruled out.

HEAVY RAIN POTENTIAL: The high resolution NAM model hints that over two inches of rain could fall south of Birmingham tomorrow and tomorrow night…

The NWS might consider a flash flood watch this afternoon since the ground is still relatively saturated from the big rains this past Sunday night and Monday morning.

APRIL COLD SNAP: The other issue is the potential for frost/freeze Wednesday morning. Tuesday will be a raw, cold day with a chilly north wind…. sure looks like many places won’t get out of the 40s. Some possibility some communities north of Birmingham, near the Tennessee border, might even have a hard time getting out of the 30s.

Models bring temperatures down into the 30 to 35 degree range around daybreak Wednesday…

Growers will need to plan accordingly. Colder pockets over North Alabama will most likely reach the 20s.

Stay tuned for updates through the day as new model data arrives…

Nice Sunday but Stormy Monday

Sun, 04/13/2014 - 04:49

No Weather Xtreme Video this morning due to travel from South Padre Island, TX, back to Helena, AL. James Spann should have the next video first thing on Monday morning.

Not a great deal of change to the forecast thinking from yesterday. Looks like a very nice Sunday for Central Alabama with clouds increasing later today but temperatures climbing into the lower 80s for highs.

Monday will be a stormy day with the potential of two serious issues – severe thunderstorms and heavy rain. SPC has outlooked an area for the standard slight risk of severe storms across the Southeast US that covers all of Alabama. All modes of severe weather will be possible including a few tornadoes. In addition to the severe weather threat, rain could be heavy at times which will bring streams that are going down from the last big rainfall up again quickly. Flash flooding will also be an issue in areas experiencing the heaviest rainfall. Widespread rain of 1 to 2 inches is likely with 2 to 3 inches possible in some locations.

Day 2 Outlook for Monday

The front and the upper trough should move by Tuesday morning paving the way for improving weather by Tuesday afternoon as lots of people get their income taxes filed. The front should usher in drier but much colder air into the Southeast. Patchy frost will be possible on Wednesday morning as morning lows dip into the middle 30s. Sunshine Wednesday should bring afternoon highs back into the middle 60s.

Thursday will be a nice day as clouds once again begin to increase ahead of yet another weather system and temperatures recover. Morning lows should fall back only into the 40s with the afternoon high approaching 70.

Stupendous Weather this Weekend

Sat, 04/12/2014 - 13:24

Hard to find anything to complain about with today’s weather across Southeast. Mostly sunny skies with just a few passing cumulus clouds are giving us all ample sunshine and blue skies. All locations across Central Alabama are well into mid and upper 70s this afternoon, as a light south winds blows keeping us very comfortable.

The incredible weather will last the rest of today and into the overnight hours as we will stay mostly clear. Lows tonight for most of Central Alabama will settle back into the mid-50s. Tomorrow, we can expect a near repeat of today as mostly sunny and warm conditions will dominate Alabama’s weather. Only differences will be afternoon highs are expected to be a few degrees warmer on Sunday, and late in the day, we will certainly begin to see clouds increasing as a storm system to our west develops.

We will have to watch this storm system as we head into Monday, as the SPC has outlined much of Alabama in their standard slight risk for severe weather. Monday morning, storms will be ongoing across the Mississippi River Valley as a cold front pushes east. These storms will likely arrive into the area during the day Monday as a strong line of storms. A lot of uncertainty with the forecast of these storms as some of the model data just shows this as a rain event while others hint at a threat for storms. Nevertheless when it comes to Alabama weather, expect the unexpected.

If severe storms do impact Alabama they will more than likely be associated with damaging winds and large hail, but an isolated tornado or two cannot be ruled out. The risk area covers much of Alabama including the cities of Mobile, Montgomery, Demopolis, Tuscaloosa, Birmingham, Cullman, and Decatur. Once again, this threat would not be until Monday and the weather the rest of this weekend will be fantastic.

Great Weekend for Central Alabama

Sat, 04/12/2014 - 08:13

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.

Great weekend in store for Central Alabama with surface high pressure nosing across the Southeast US while the action begins to develop to our west.

A strong trough will come out of the southern Rockies on Monday preceded by a series of short waves. This will bring rain and perhaps thunderstorms to the area late Sunday night into early Monday morning for round one while the main trough hangs back to bring us round 2 on Monday afternoon and evening. Some of the storms could be strong to severe on Monday afternoon with all modes of severe weather possible including isolated tornadoes. The two major threats will be damaging wind as well as concerns for additional flooding or flash flooding as streams and rivers across the area remain pretty full. Rainfall totals on the order of 1 to 2 inches are possible with perhaps some higher amounts to 3 inches in the heavier storms. While the rivers and streams are responding to the dry weather by coming down some, they will still be running pretty full on Monday, so any significant rain could bring them back up quickly.

The upper trough takes its time but finally comes across Alabama on Tuesday. This should bring an end to the rain by late morning and provide us with clearing skies by late afternoon. It will also usher in some cooler air with the potential for readings in the upper 30s on Wednesday morning.

But the ridge builds in across the East Coast returning us to warmer temperatures for Thursday and Friday. By Friday, another strong trough begins to move out of the western US with moisture returning from the Gulf of Mexico. This will set the table for another round of wet weather for next Saturday with the potential for strong storms though it does not appear that impressive at the moment.

Looking out into Week 2 or voodoo country, a strong ridge builds into the eastern US around the 24th of April, while yet another strong trough digs into the Rockies. This strong trough will eject out across the Central Plains and Mississippi River Valley around the 26th and 27th, and the GFS is surely showing a substantial trough with what could be some pretty chilly air as well as the potential for severe storms. Not unexpected considering it is April.

Thanks for tuning into the Weather Xtreme Video. I will be traveling back to Alabama on Sunday morning from the National Tropical Weather Conference, so I will be unable to prepare a video in the morning. I’ll do my best to post some forecast notes. Enjoy the great weekend and Godspeed.

Warm, Dry Weekend Ahead

Fri, 04/11/2014 - 14:28

**No afternoon Weather Xtreme video today… I am at Regions Field for a special Weather Radio giveaway tonight at the Barons game**

WARM WEEKEND: A delightful weekend is ahead for Alabama; expect a partly to mostly sunny sky tomorrow and Sunday; highs will be near 80 degrees both days.

SPC maintains a standard “slight risk” of severe weather for areas west of Alabama Sunday; much of Arkansas, Louisiana, East Texas, and East Oklahoma is included in that outlook.

RAIN BY MONDAY: Showers and storms return to Alabama Monday and Monday night; severe weather parameters remain unimpressive, and severe weather (at least on an organized basis) is not expected for now. Rain amounts of 1 to 2 inches are likely, and the rain will end Tuesday as colder and drier air moves into the state. Parts of North Alabama won’t get out of the 50s Tuesday with a chilly north wind of 12-22 mph making it feel colder.

Wednesday morning will be cold, and the 12Z GFS suggests much of North and Central Alabama will drop into the 30s… seems like the potential of a late season frost or freeze is very real.

Growers will need to monitor temperature forecasts closely in coming days. A warming trend begins Wednesday afternoon, and for now Thursday and Friday look dry.

GULF COAST WEATHER: Sunny days, fair nights through Sunday. Rain and storms are likely Monday and Monday night; the rain ends Tuesday and the rest of next week will be dry. Highs on the immediate coast will be in the 67-70 degree range because of the cooler ocean water (sea water temperatures are in the mid 60s), but inland some low 80s are likely over the weekend.

Severe Tropical Cyclone Ita

Fri, 04/11/2014 - 08:46

We are still a few months away from the start of the Atlantic Hurricane Season, which begins June 1. However, in the southern hemisphere, around Australia they are still in the tropical cyclone season for about another month.

A very dangerous and destructive storm is impacting parts of Australia currently. Severe Tropical Cyclone Ita made landfall earlier today along the northern Australia Coast in the state Queensland. Ita is a very powerful storm as maximum sustained winds were 135 knots or 155 mph with wind gusts to 165 knots or 190 mph. Looking at the system, there is no doubt that Ita is a very strong storm being fairly symmetrical, with a well-developed eye.

What always fascinates me about southern hemisphere storms is they spin backwards to what we are use to seeing in the northern hemisphere. In the southern hemisphere, cyclonic flow is clockwise verses the counter-clockwise flow we see in the northern hemisphere.

At 1pm EST Friday, Severe Tropical Cyclone Ita was situated over the
northwestern Coral Sea and moving south southwestwards towards the north
Queensland coast.

Severe Tropical Cyclone Ita is expected to shift inland during Saturday though
remain quite close to the coast. It will then most likely move southeastwards
off the southern tropical or central coast on Monday and into the Coral Sea. It
has some potential to redevelop though will be encountering a less favorable
environment and should also shift further southeast away from the east
Queensland coast.

Delightful Weekend Ahead; Storms By Monday

Fri, 04/11/2014 - 06:02

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.

DRY THROUGH SUNDAY: Weather like this sure makes our job easy; we expect mostly sunny mild days and fair nights through Sunday. Today’s high will be in the 75-78 degree range, then we top out close to 80 tomorrow, with low 80s possible Sunday.

To the west, a large “slight risk” severe weather risk is defined Sunday west of Alabama…

EARLY NEXT WEEK: That storm system moves into Alabama with a good chance of rain and thunderstorms Monday, Monday night, and into at least a part of the day Tuesday. The good news is that severe weather parameters are very unimpressive, and at this point we just expect a good rain event with only a minimal severe weather threat. Rain amounts of 1 to 2 inches are likely, so major flooding is not expected, but the rain could be heavy at times.

The rain will end from west to east Tuesday, and noticeably cooler air blows into the state with brisk north winds. Some parts of the Tennessee Valley might have a hard time getting out of the 50s Tuesday afternoon.

Wednesday morning will be cold; it is likely we will see 30s in many areas, and again there is potential for frost across the colder valleys. Growers once again will need to monitor temperature forecasts.

Thursday and Friday of next week look dry with a warming trend. See the Weather Xtreme video for the maps, graphics, and details.

WeatherBrains 428: Jackass What?

Fri, 04/11/2014 - 05:15

WeatherBrains Episode 428 is now online (April 10, 2014). If you are crazy about weather, this is THE netcast audio program for you!

This is the regular weekly WeatherBrains podcast, but it is a somewhat special edition because it was recorded on a Thursday night AND 75 percent of the available WeatherBrains crew were together on South Padre Island, TX, attending the National Tropical Weather Conference. The topic for the show is, of course, tropical weather. And we weare fortunate to have two previous WeatherBrains guests on the show, both former National Hurricane Center directors, Max Mayfield and Bill Read. Listen to the show to get the inside stories from some very experienced meteorologists who have dealt with some major issues surrounding tropical weather. This is the behind the scenes stuff that you cannot get anywhere else.

The WeatherBrains crew and guests on episode 428 at the National Tropical Weather Conference in South Padre Island, TX.(L to R: Brian Peters, Nate Johnson, Bill Read, Max Mayfield, and Bill Murray).

Our email bag officer was not available, so a double dose of the mail bag will probably come next week.

Listener Surveys: Okay, we continue to drive this topic into the ground, but we really do like to hear from you. Many thanks to everyone who has taken the time to fill out the Listener Survey. The survey takes just a minute or two to complete and provides us with an opportunity to learn where you are and hear your thoughts and comments on the show. Click here to take the survey.

Sunny Days Through Sunday

Thu, 04/10/2014 - 15:39

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.

BIG WARM-UP: As expected, some of the traditionally colder spots across North Alabama saw some frost early this morning; Black Creek near Gadsden dropped to 33. But, we have warmed over 40 degrees in some places this afternoon as most communities are in the mid 70s. Hard to find a decent cloud in the sky.

DRY THROUGH SUNDAY: Delightful weather continues. Mostly sunny warm days, fair cool nights. Upper 70s tomorrow; highs around 80 Saturday, with potential for low 80s Sunday.

To the west, SPC has a severe weather risk defined for areas west of Alabama Sunday afternoon and Sunday night.

EARLY NEXT WEEK: A dynamic weather system will bring rain and thunderstorms back to Alabama Monday into Tuesday. The GFS is a little faster, the ECMWF a little slower; for now we will project the primary window for rain from 12:00 noon Monday through 12:00 noon Tuesday, but understand that might need to be adjusted as we get closer to the event.

At this point there is no real focused surface low, and instability values are low, so the severe weather threat doesn’t look very high, but this is mid-April and that might change in coming days. No doubt it will bring a good soaking with rain amounts of one to two inches statewide. See the Weather Xtreme video for the maps, graphics, and details.

Colder air arrives Tuesday night, and we might have a situation where colder valleys and protected areas go into the low to mid 30s again either Wednesday or Thursday morning (much like what we experienced this morning).

VOODOO LAND: Another strong storm system will bring active weather to Alabama around April 19-20. See the video for more details.

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… we have moved the time to 9:30p CT to accommodate our crew at the National Tropical Tropical Weather Conference on the Texas coast.

Atlantic Hurricane Season Forecast from Klotzbach/Gray

Thu, 04/10/2014 - 11:31

Dr. Bill Gray just finished speaking at the Tropical Meteorology Conference at South Padre Island, discussing the challenges of seasonal hurricane forecasting and the precursors that they use.

He turned it over to Dr. Phil Klotzbach to announce their 2014 Atlantic Hurricane Season Forecast. Here are the numbers, showing their forecast and the 30 year average (1981-2010).

Named Storms: 9 (12.0)
Named Storm Days: 35 (60.1)

Hurricanes: 3 (6.5)
Hurricane Days: 12 (21.3)

Major Hurricanes: 1 (2.0)
Major Hurricane Days: 2 (3.9)

ACE*: 55 (92)
*ACE is Accumulated Cyclone Energy, a measurement of the wind energy expended by tropical cyclones. It is a better parameter for looking at the overall intensity of a storm or season.

NOTES
…Klotzbach credits the pending El Nino for the below average forecast.
…The Atlantic is at its coolest since 1994 as well.

ANALOGS
Some analog seasons cited:
…1957 Hurricane Aubrey killed at least 416 people in SW Louisiana
…1963 Flora killed over 7,000 people in the Caribbean
…1965 Hurricane Betsy struck Bahamas, South Florida and Louisiana
…1997 Hurricane Danny flooded Alabama coast
…2002 Lili impacted Gulf Coast

I cite the example storms from the analogs as a reminder that it only takes one story to make it a bad hurricane season. So even though a below average season is forecast, that is academic if storm hits you.

Here is the full forecast.

Your Weekly U.S. Drought Monitor Update

Thu, 04/10/2014 - 10:31

Recent rains in many parts of the country have help alleviate some of the drought conditions, but looking at the map below, we continue to see a lot of dry areas across the Plains, Texas, the Southwest, and along the West Coast. We still see exceptional drought conditions affecting California, Nevada, Texas, Oklahoma, and Colorado.

For Alabama, WOW, what a difference a week makes. The rains we received earlier this week have all but squashed any abnormally dry conditions across the state. Last week these conditions covered portions of the Wiregrass Region as well as locations from Dallas County to Cleburne County, but with most of these areas receiving 2-4 inches of rain this week, everything is back to normal for now.

The only part of the state that is still experiencing drought and abnormally dry conditions is in the northwestern part of the state. Moderate drought conditions are occurring in portions of Lauderdale, Colbert, and Franklin Counties, where it amounts to 1.32% of the state being affected. That is down from 3.37% last week, meaning the area being impacted decreased by 2.05%.

The abnormally dry conditions continue to impact locations in Lauderdale, Limestone, Lawrence, Colbert, and Franklin Counties. As stated earlier, these conditions covered much more of the state last week as 24.55% of the state was being impacted. This week, it has dropped significantly and is at 3.82% of the state. That is a decrease of 20.73% in the area suffering from the dry conditions.

With more rain in the forecast to start next week, hopefully we will see conditions continue to improve for our northwestern counties as well as no new areas develop elsewhere.

Big Warm-Up Today

Thu, 04/10/2014 - 05:52

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.

COLD START: Many North/Central Alabama communities are in the 30s this morning. Some temperatures just before daybreak…

Black Creek 33
Fort Payne 34
Gadsden 36
Cottondale 36
Haleyville 36
Valley Head 37
Pleasant Grove 38
Cullman 39
Concord 39

Look for sunshine in full supply again today, and we warm into the mid 70s this afternoon.

TOMORROW THROUGH THE WEEKEND: This fantastic spring weather will continue, with sunny days and fair nights. We reach the upper 70s tomorrow, and the high over the weekend will be around 80 degrees.

We note that SPC has introduced a severe weather risk for areas west of Alabama on day 4, which is Sunday…

MONDAY/TUESDAY: A rather dynamic weather system will bring a round of showers and thunderstorms to Alabama. The GFS hints the primary surface low will be well to the north of here, and at this point the severe weather risk doesn’t look overwhelming, but then again this is mid-April and you have to watch any storm system closely. Looks like rain amounts of around one inch, not enough for a big flooding issue.

The GFS moves the rain out quickly Monday night, but the ECMWF is slower, and keeps rain going through Tuesday morning. Drier and cooler air follows the rain for mid-week… Wednesday morning looks cold, and like this morning there could be 30s across colder pockets of North/Central Alabama. See the Weather Xtreme video for the maps, graphics, and details.

AT THE BEACH: Sunny days, fair nights through Sunday. Highs along the immediate coast will be in the upper 60s, with 70s inland. Next chance of showers and storms will come Monday… sea water temperatures are in the mid 60s.

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 live on “James Spann 24/7″ on cable systems around the state, or on the web here.

Severe Clear

Wed, 04/09/2014 - 14:35

**No afternoon Weather Xtreme video today; we are in Oxford programming NOAA Weather Radio receivers at the Publix; come see us if you need help… we will be here until 6:30 p.m.**

CHILLY NIGHT: Most communities will wind up in the low 40s early tomorrow with a clear sky and light wind, but keep in mind some of the traditionally colder spots will see a low in the mid to upper 30s with a touch of light frost possible. Nothing widespread or really damaging.

SPECTACULAR SPRING WEATHER: Doesn’t get any better; we expect sunny mild days and clear cool nights through Sunday. Highs in the mid 70s tomorrow, and upper 70s Friday and over the weekend. Some places could touch 80 degrees Saturday and Sunday afternoon.

STORMS RETURN EARLY NEXT WEEK: The 12Z GFS continue the idea of a band of showers and storms moving into Alabama Monday…

This will be a dynamic system, and we will monitor it in coming days for potential for heavy rain and severe thunderstorms. Colder and drier air will follow the rain Tuesday and Wednesday.

Dry Through The Weekend

Wed, 04/09/2014 - 06:06

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.

COOL APRIL DAY: We are starting the day generally in the 40s, and we project a high between 64 and 68 degrees this afternoon… below the average high of 73 for April 9. The sky will be mostly sunny.

Tonight will be rather chilly; most communities will see a low around 40 degrees early tomorrow, but the traditionally colder pockets will drop down into the mid to upper 30s with potential for some scattered light frost. A warming trend begins tomorrow afternoon with a sunny sky and a high in the mid 70s.

FRIDAY THROUGH THE WEEKEND: Doesn’t get any better. Sunny days, fair nights. Highs 77 to 80, lows in the 50s.

NEXT WEEK: Global models continue to advertise a fairly dynamic weather system impacting Alabama early next week with rain and thunderstorms Monday into Monday night. For now it doesn’t look like a big severe weather setup, but it is really too early to evaluate the severe weather/heavy rain potential. Cooler and drier air arrives Tuesday; see the Weather Xtreme video for the maps, graphics, and details.

AT THE BEACH: Mostly sunny days and fair nights tomorrow through the weekend. Highs on the immediate coast will stay in the 60s because of the cooler ocean water, but 70s are likely just few miles inland. Sea water temperatures remain generally in the mid 60s. Next chance of wet weather on the coast will come on Monday.

WEATHER RADIO PROGRAMMING: We will be at the Publix in Oxford today from 3:30 until 6:30… if you need your weather radio programmed, have questions, or need to buy one, come see us.
