More Storms Expected

ABC 33/40 Weather Blog - Sun, 07/05/2015 - 06:59

A quick look at the radar this morning showed much of the action occurring across South Alabama where the boundary sagged last night. The flash flood watch issued yesterday was allowed to expire this morning. Additional showers are expected to develop later today in the warmth of the afternoon.

At 500 millibars, the small upper low was located over the eastern half of Tennessee as it slowly migrates northeastward reducing its influence on our weather pattern. As the low gets absorbed into the primary westerly flow and moves into the Mid-Atlantic States, the pattern across the Southeast US will be replaced by gradual ridging as the Bermuda high builds across the southern US from the western Atlantic. This upper air pattern should favor a return to more diurnally driven showers and storms for the week ahead as temperatures also climb back into the lower 90s.

With the westerlies located along the northern tier of the US, another cold front will approach the Ohio and Tennessee River valleys at mid-week but is expected to wash out before we can see any kind of air mass change. This keep the moist air mass in place and keeps scattered showers and storms in the forecast for much of the week ahead.

The Atlantic Basin remains especially quiet as the South Atlantic remains covered by a large mass of dry Saharan air. There was a little more action in the Eastern Pacific where a tropical depression is likely to form early next week well out in the Pacific.

The SPC in Norman, OK, has continued a marginal risk of severe storms along the Gulf and Southeast US coasts for today with an enhanced risk of severe storms centered mainly on South Dakota later in the day. They have only a marginal risk area ahead of that front for Monday or Day 2.

Headed to the beach? About 6 to 8 hours of sunshine daily for the Central Gulf Coast heading into next week, from Dauphin Island to Panama City Beach. Storms will be more numerous today, but each day in the week ahead there will be a decent chance for a passing storm from time to time, fairly typical with the daily sea breeze effect. Highs on the immediate coast will remain in the mid to upper 80s, with lower 90s inland. Sea water yesterday afternoon at Perdido Pass at Orange Beach was reported to be 81 degrees.

Looking out into voodoo country, the GFS continues to advertise the potential for the trough to stay a feature across the eastern US into Week 2. While the ridge builds and decays, the presence of the overall trough across the eastern third of the country is certainly a positive sign for keeping any extreme heat at bay.

James Spann will be back with the next edition of the Weather Xtreme Video first thing on Monday morning. Check back here often for updates on the Central Alabama weather.

Afternoon Update

ABC 33/40 Weather Blog - Sat, 07/04/2015 - 14:05

After the very active start to the day, we have see a lull in the action and actually have see some decent sunshine across portions of the state. The breaks in the cloud cover, as seen below, are allowing instability to build and we are once again seeing convection blossom across portions of the Southeast.

Under these puffy white clouds, we are seeing numerous showers and storms. These storms are producing a lot of lightning, gusty winds, intense rainfall, and possibly even some hail. A quick look at the radar shows a cluster of storms over West Alabama and they are tracking towards the east. It looks as though the bulk of the activity will be staying just to the south of Interstate 20 corridor.

Click image to enlarge.

For the rest of today we will continue to see showers and storms develop across Central Alabama and these could affect some of those fireworks shows, but hopefully we will see enough breaks in the action that will allow the shows to go on. Heading into Sunday, expect more of the same across the state. A stall frontal boundary to our north, and a warm and moist air mass will allow for numerous showers and storms to develop once again tomorrow. These storms will produce loads of lightning, but flooding could be the greatest concern. A reminder, much of Central Alabama remains under a flash flood watch through Sunday morning.

Watch May Be Issued

ABC 33/40 Weather Blog - Sat, 07/04/2015 - 11:46

AREAS AFFECTED…PORTIONS OF CENTRAL/SRN MS…EXTREME W-CENTRAL AL

CONCERNING…SEVERE POTENTIAL…WATCH POSSIBLE

PROBABILITY OF WATCH ISSUANCE…40 PERCENT

SUMMARY…THUNDERSTORMS MAY POSE A RISK FOR ISOLATED DAMAGING GUSTS
THROUGH MID AFTERNOON. TRENDS IN THUNDERSTORM COVERAGE WILL BE
MONITORED AND A WATCH IS POSSIBLE PRIOR TO 18Z.

DISCUSSION…LATEST RADAR AND VISIBLE SATELLITE IMAGERY SHOW AN
EAST-WEST ORIENTED OUTFLOW BOUNDARY BISECTING THE STATE OF
MISSISSIPPI…WITH RECENT MOTION TO THE SOUTH AT AROUND 10 MPH. A
WEAKENING UPPER LEVEL SHORTWAVE TROUGH WAS LOCATED ACROSS THE
LOWER/MID MISSISSIPPI RIVER VALLEY. THUNDERSTORMS WERE SLOWLY
INTENSIFYING ALONG THE LEADING EDGE OF A CONVECTIVELY-GENERATED COLD
POOL OVER WEST-CENTRAL MS…AND ALSO IN THE VICINITY OF THE E-W
BOUNDARY FROM NEAR JACKSON TO JUST NORTH OF MERIDIAN. AMPLE HEATING
OF THE MOIST AIR MASS SOUTH OF THE OUTFLOW BOUNDARY WILL RESULT IN A
MODERATE/STRONG SURFACE-BASED INSTABILITY…AND 25-35 KTS OF WSW
FLOW IN THE 2-4 KM AGL LAYER IS FAVORABLY ALIGNED WITH OVERALL STORM
MOTIONS. A RISK FOR DAMAGING WINDS WILL EXIST THROUGH THIS AFTERNOON
WITH THE EASTWARD-MOVING LINE OF THUNDERSTORMS GENERALLY NEAR AND
SOUTH OF THE I-20 CORRIDOR…AND AN ISOLATED THREAT WILL EXIST WITH
THE STRONGER STORMS DEVELOPING FARTHER EAST INTO EAST-CENTRAL MS/FAR
W-CENTRAL AL.

RADAR TRENDS WILL BE MONITORED AND A WW IS POSSIBLE PRIOR TO 18Z.

Cool Pic of the Day

ABC 33/40 Weather Blog - Sat, 07/04/2015 - 10:16

Here is a cool graphic of the current visible satellite image with radar echoes superimposed.

That delineated line is the outflow sinking south.

You can see clearing out behind it. The southward impetus of the outflow and the low level southerly surface winds are blowing off the tops of the clouds, resulting in the striations.

Additional storms are already firing back in western Mississippi, Louisiana and Arkansas. They are the result of another wind maximum moving through the upper trough just to our northwest that results in diffluence or spreading apart aloft, which creates lift at the surface!

Record Rainfall for the Date

ABC 33/40 Weather Blog - Sat, 07/04/2015 - 08:33

3.12 inches of rain has fallen at the Birmingham Airport so far today through 8:15 a.m.

This is a new record rainfall for July 4th in the Magic City.

The former record (2.10″) was recorded in the first year we have reliable records, 1895!

That same year, the high was only 80F. We might not see 80F today. It we stay at 76F or cooler, it will tie or beat the record cool high for Independence Day. A few breaks in the clouds should prevent that from happening, but it could be a top ten coolest Fourth of July at Birmingham. And it certainly is the wettest!

Will It Rain All Day?

ABC 33/40 Weather Blog - Sat, 07/04/2015 - 08:21

The answer is…no.

Almost everyone will see rain today, but there will be breaks.

The current band of rain covering nearly all of North Central Alabama is beginning to slowly diminish at this hour. It should end over western Alabama by 10 a.m. and in the Birmingham area by noon.

Locations along and east of I-65 should see a 2-4 hour break in the rain through early afternoon.

But additional rain and storms will move into and form over western Alabama starting around noon, and this activity will work its way across the area through the afternoon with most folks seeing another 2-3 hours of rain.

Based on the HRRR model, which we are depicting above in a 15 hour loop, the rain should start again in Birmingham around mid-afternoon and last 2-3 hours. Then there could be a nice break for several hours, perhaps allowing Thunder on the Mountain and other fireworks displays to go off without any rain problems.

None of this is poured in concrete and is based on model data, so stay tuned.

LATE NOTE
3.12 inches at Birmingham Airport so far today through 8:15 a.m. This is a new record rainfall for July 4th in the Magic City. The former record (2.10″0 was recorded in the first year we have reliable records, 1895!

Serious Situation in Birmingham Metro

ABC 33/40 Weather Blog - Sat, 07/04/2015 - 08:04

A serious flash flooding situation is in effect in the Birmingham Metro.

John Talbot reports that Homewood Police and Fire have a major water rescue/evacuation in progress at apartments off Lakeshore Dr.

Birmingham Fire and Rescue also performing water rescues.

Please, on this Fourth of July, turn around, don’t drown! Don’t put first responders and your family in jeopardy by driving into flood waters.

Here is the current radar:

More heavy rain continues across southern parts of the Birmingham Metro at this hour. The heaviest rain is in the I-459 corridor around Hoover up to Liberty Park. Thunderstorms have really increased in that area with lots of lightning and booming thunder. I have picked up 2.32 inches of rain since midnight in Vestavia off Acton Road.

Rain is slowing over the City of Birmingham, which is good news, but serious flash flooding continues.

Soggy Fourth of July

ABC 33/40 Weather Blog - Sat, 07/04/2015 - 07:15

Nature is providing plenty of fireworks for the fourth of July in the form of a train of thunderstorms that stretched from Southeast Oklahoma all the way to North Georgia. Flash flood watches were posted for a sizable chunk of the Southeast US including much of the northern half of Alabama through Sunday morning. There is little change likely to occur in this weather pattern over the next 36 to 48 hours, with potential for the watch area to be extended and additional flash flood warnings added for counties generally along and north of the Interstate 20 corridor. Rain and clouds were keeping temperatures down considerably with highs only expected to reach the lower 80s. Birmingham only reached 80 yesterday for the daily high. This is a look at the latest radar image.

The storm total precipitation estimate also shows the impact of the training of these storms with that red area in Marion County with an estimated 8 to 10 inches of rainfall with more to come.

The upper level low will move slowly into the Central Appalachians by Monday, so I expect rainy weather to stay with us into Sunday. But by Monday as the low gets caught up by the main westerlies, we should see the atmosphere dry out at least somewhat dropping us back to more typical afternoon and early evening storms for much of the week ahead. Again, the additional clouds and presence of showers will help to hold the heat off until mid-week when we should see highs once again near seasonal values as we record values into the lower 90s.

The training of echoes today and Sunday will keep the flash flood threat high across much of Central Alabama. Additional rainfall values of 2 to 4 inches will be possible over the weekend with some higher values likely where the strongest storms occur. Remember, turn around, don’t drown. Don’t risk your life by driving into areas where water covers the roads to an unknown depth.

While the flash flood threat is very high, we also continue to see potential for isolated strong to severe storms. SPC has much of the Southeast US in the area from North Georgia westward to Oklahoma in a marginal risk area. But as the upper low moves out early next week, the risk for strong storms should drop.

The Atlantic Basic continues to be quiet thanks to the extensive area of dry air over the South Atlantic. The Eastern Pacific was a little more active with a couple of areas of disturbed weather but no named storms for now.

For folks headed to the beach, look for about 4 to 7 hours of sunshine each day through much of next week with the risk of occasional passing thunderstorms from Dauphin Island eastward to Panama City Beach. Highs will remain in the mid to upper 80s on the immediate coast, with lower 90s inland. Sea water temperatures are mostly in the low to mid 80s.

Looking out into Week 2, the long range GFS suggests another substantial ridge to our west which will bring back highs in the 90s, but the pattern evolves back to more of a trough over the eastern US by the 19th of July suggesting at least a limit to some of the summer heat.

The overall weather situation for Central Alabama remains highly fluid, so please check back here often for updates. A flash flood warning was issued for Jefferson County until 9:30 am while I was working on this post. I plan to have the next Weather Xtreme Video posted here Sunday morning.

More Showers/Storms

ABC 33/40 Weather Blog - Fri, 07/03/2015 - 22:59

Another round of showers and thunderstorms is moving across much of the same area that experienced a couple of rounds of storms this afternoon.

Showers and storms extend from the Alabaster area down through Calera, Maplesville and Marion.

Other storms have formed ahead of this main activity along US_80 from Demopolis to Selma and Montgomery.

Lots of lightning, gusty winds and heavy rain, but the storms are not expected to become severe.

Showers and storms are expected to be common through the morning hours in about the same areas.

Update on the Storms

ABC 33/40 Weather Blog - Fri, 07/03/2015 - 20:00

Four areas of storms to worry about tonight:

1. Chilton County storms are quite strong, but not severe. Lots of lightning and heavy rain as well as gusty winds. They are straddling I-65 around Lomax and Clanton. They will be approaching Lake Mitchell shortly.

2. Montgomery Area: strong storms with lots of lightning in the Montgomery area.

3. West Central Alabama: A couple of isolated strong storms are over northwestern Tuscaloosa County and northwestern Greene County. The Tuscaloosa storm will affect areas well north of the City of Tuscaloosa, the University of Alabama and Northport, mainly affecting rural areas near and around Moores Bridge Samanatha as it moves east southeast. This storm will stay just north of Lake Tuscaloosa. The Greene County storm will cross I-59 around Eutaw and Knoxille before 8:15.

4. Approaching Pickens and Lamar Counties: Strong to severe storms in eastern Mississippi from Amory to Aberdeen to West Point will be reaching West Alabama’s Lamar and northern Pickens Counties starting around 815 p.m. The storms should reach Vernon before 8:30 and Millport before 8:45.

The storms are not severe at this time, but have the potential to become severe thanks do some fairly significant wind shear for summer. All of the storms will be capable of deadly lightning, very heavy rain and strong gusty winds.

The polygons in peach are Significant Weather Alerts from the NWS.

Severe Thunderstorm Watch in Our Future?

ABC 33/40 Weather Blog - Fri, 07/03/2015 - 18:20

Strong thunderstorms have developed afternoon across Central Alabama. One storm that has moved out of Chilton County and is now crossing Coosa County around Lake Mitchell has produced hail to 1.5 inches in diameter, including numerous reports of large hail back in Bibb County and in the Jemison area. Numerous reports of 1 inch hail were received from around Jemison. Some trees were also reported down in Bibb County.

0.72 inches of rain was reported in Thorsby in 20 mins according to @nightnurse24 (Tracy McDaniel). Justin Gentry reported 0.71 inches in Jemison. Back in Tuscaloosa County, Wallace Williams reported 0.72 inches at Cottondale.

This storm is a little weaker now, but a trailing storm is catching up to the first storm and the two are about to merge over Coosa County west of Rockford.

Other storms are over northern Hale and much of Bibb County at this hour. They will be moving across much of Shelby County over the next couple of hours. These storms are not as strong as the Chilton/Coosa County storms for now.

The storms are tapping an instability-rich airmass to the south of an outflow boundary that settled into North Central Alabama this morning. South of I-20, CAPE values are over 2,000 j/kg. The storms should continue to be strong for the next few hours thanks to decent winds aloft at about 18,000 that are blowing across Central Mississippi and Central Alabama. These winds of up to 50 mph are producing a decent amount of speed shear that is allowing our storms to lean over and not choke on their own updrafts like garden variety summer storms do.

This speed max will be shifting eastward across Alabama this evening. As it does, it will allow storms to continue strong. A complex of thunderstorms back in western Mississippi and additional strong to severe storms over eastern Mississippi will track west to east across the state through the evening and overnight.

A severe thunderstorm watch may be issued for Central Alabama a little later.

Damaging winds and some hail will be the severe threats, along with very heavy rain and intense lightning.

Stay weather aware tonight, especially if you have outdoor holiday plans.
