A strong thunderstorm northwest of Vernon in Lamar County has the potential for produce wind gusts to 60 mph or greater.
It will move northeast toward Sulligent and Beaverton.
It also is accompanied by lots of dangerous lightning and torrential rain.

Attached is my satellite imagery, analysis and discussion of the features seen on satellite now that should affect Alabama weather at least through Tuesday and maybe as far out as Wednesday or even Thursday…oh my!
One note for later this afternoon and at least the first part of tonight…a little nervous for the northern third to northern half of Alabama with the Arkansas/southeastern Missouri wave going by to the north. The wave will be going by far enough north to I believe keep the severe from getting to much out of hand at least the further south you go in the state.
Maybe the case for heavy rain as well as that real high moisture (almost 2″ precipitable water in Central Gulf) probably won’t have a chance to get sucked up to far north. But if that moisture can get north…then and only then would there be more severe weather and heavy rain than what is being forecasted.
Will have to keep an eye on the total precipitable water satellite product top see if the small red in the Gulf expands north (which at least for now does not look to be the case).
Now, I have to go mow my wet lawn here in D.C. and hope I can get my garden started after things dry out some later in the weekend. Oh, by the way, have another nice weekend…I am envious.
From pine beetles to quesadillas, from Honda to Highlands and from Nike to concertinas, our friends at Alabama NewsCenter were busy this past week reporting good news.
A line of strong showers is dropping into Central Alabama late this afternoon.
It extends from northern Marion County into northern Winston to near Cullman, then into northern Blount County, and on to near Albertvlle and Fort Payne.
It has a history of producing strong wind gusts and even brought down some trees and power lines southeast of the City of Madison in Madison County, west of Huntsville.
Winds gusted to 40 mph at Huntsville International Airport and 30 mph at Decatur and Muscle Shoals.
Winds will gust in excess of 40 mph as this line drops south, especially over Blount and Etowah Counties.
The tops of the showers are under 20,000 feet, so no lightning. There just isn’t much instability, and dewpoints are only in the upper 40s and lower 50s.
The line will reach Birmingham a little after 7. Gadsden should see the activity before 615 p.m. Anniston around 645 pm.
Well, they have avoided the rain successfully throughout the race at Talladega today. Hopefully, the race will be finished before it arrives.
Right now, there is less than 50 laps to go and the nearest shower looks like it will miss the track. Heavy will not arrive until after 4 30 p.m. unless there is new development.
THE ALABAMA WEATHER SITUATION
A large area of showers and thunderstorms is pushing east and northeast across areas west of I-65 this afternoon. The strongest storms are:
…over the intersection of Fayette, Marion, Winston Counties near Nauvoo.
…over Bibb, southern Tuscaloosa, western Chilton and Autauga Counties.
In the Birmingham area, a strong storm is approaching Lake View, and another is west of Alabaster. The Metro will experience lots of lightning and some heavy rain and gusty winds
A new storm is forming on the Talladega/Shelby County line between Columbiana and Sylacauga.
The fifth month of the year is one of my favorites in Central Alabama. We see some of the finest weather of the year, with runs of fine, warm and sunshine filled days. It reminds me a lot of October, its closest cousin, but generally warmer and somewhat stormier. The average percentage of possible sunshine is 66 percent, equal to October, which is the other sunniest month of the year.
The average high and low for the month in Birmingham is 81.5F and 59.7F respectively. At the start of the month, the average high is 78F, but it rises to 85F by the end of the month. Overnight lows really warm, rising from 55F on May 1st to 64F on the 31st. The coldest May reading ever in the Magic City is 36F on May 4, 1971. The warmest reading ever in May was 99F on May 28, 1962 and May 29, 1898. It generally reaches 90F or warmer 1.9 days in the month.
Heating degree days are nearly zero in May, but cooling degree days start to really rise as we head toward the unrelenting heat of summer.
May used to be a drier month than April. Until 2003 that is. 5.71 inches of rain fell on the 7th that month, which skewed the average higher. The average May rainfall at the Birmingham Airport jumped from 4.4 inches to 4.99 inches because of that single event. A tremendous flash flooding event occurred across Central Alabama that day, with higher amounts reported just northeast of the Airport. 10.50 inches of rain fell on Edwards Lake Road and JB Elliott recorded 9.82 inches just northeast of Trussville. Not surprisingly, May 2003 went on to become the wettest fifth month with 17.22 inches of rain. The driest May on record occurred in 2000, when 0.88 inches fell.
It usually rains on 9.1 days on average, and rains more than 1 inch on 1.4 days. Thunderstorms occur on 9 days. The average dewpoint is starting to climb, rising from 49F in April to 58F in May.
An area of rain and storms is pushing northeastward across East Central Mississippi early this afternoon. Severe thunderstorm warnings are in effect for Lowndes, Noxubee, Oktibbeha and Winston Counties in eastern Mississippi. No reports of damage so far, and the NWS Birmingham is not planning on issuing severe thunderstorm warnings unless they intensify.
Tons of lightning in the storms between Columbus MS and Brooksville down to Scooba.
There is a threat for severe thunderstorms with winds to 60 mph with storms today. The threat of tornadoes is very very small, if not zero.
They will push into Alabama’s northern Pickens and Lamar Counties by 1 p.m. There are already storms over southern Lamar County around Millport and Kennedy.
In the Birmingham Metro, storms are forming from Homewood to Hoover and back to Bessemer. Just saw the first lightning stroke near Vestavia.
There is a storm northwest of Oxford. This storm brought a shower to the Talladega Superspeedway right befor ethe green flag at the Geico 500.
Showers along highway 280 in northern Shelby County may threaten the track within the hour.
Trees have been reported down in Sumter County because of this event that are not associated with thunderstorms, but with a wake low.
Tonight’s marginal and slight severe weather threat is over for Central Alabama as the area of thunderstorms has weakened as it lifted northeast into our part of the state.
Right behind it, what appears to be a wake low has developed. This feature is causing winds to gust to nearly 30 mph in spots.
Winds gusted to 28mph at Tuscaloosa and Birmingham just before 8 p.m.
Areas along and south of I-59 will see the best chance of the gusty winds.
Wake lows are caused by sinking air which descends in the wake of the weakening of a complex of storms. They often cause heat bursts in the Plains, which are characterized by strong winds, rapid drops in dewpoints and substantial rises in temperatures.
Nothing like that here tonight, but some gusty winds.
It looks like rain will be limited to areas south of areas from Selma to Montgomery.
