A look back to the west makes you think that we are going to still have an active night tonight across Alabama.
A stationary frontal boundary lies across northern Louisiana, South Central Mississippi and South Central Alabama this afternoon.
Some impressive temperature differences across the boundary, not so because of airmass change, but differential heating. Sunny skies south of the boundary have driven the mercury to 88F at Greenville, AL, while at Montgomery, it was a rain cooled 70F. It was 83F/71F at Meridian (temperature/dewpoint) while at Columbus, it was 69F/65F.
Thunderstorms were intensifying over southern Arkansas and along the Louisiana/Arkansas border. South of that, discrete cells had formed over northern Louisiana. A severe thunderstorm watch covered nearly the entire northern half of Louisiana and the Central third of Mississippi.
These storms will migrate eastward this evening, firing along the differential instability along the boundary. A large shield of rain should form over northern Mississippi and move eastward along with some embedded storms.
Along and just north of the boundary, storms will be strong to severe, gradually losing intensity as we go through the evening hours. Further south, more significant severe weather is possible.
Look for a weather watch during the evening over some part of Central Alabama. A flash flood watch continues for the northern half of Central Alabama for tonight, including the Jasper, Gadsden, Anniston, Birmingham, Tuscaloosa areas.
