Strong thunderstorms are over western Tennessee, northern Mississippi and southeastern Arkansas…moving ESE at 45 mph.
Extrapolating this movement…these cells could impact West Alabama on the following rough time schedule…
Northwest Corner of the state…9:30 -10:00 p.m.
Marion County…10:30-11 p.m.
The most dangerous looking cell is on the southern end of the line…moving toward Clarksdale MS. Shows excellent rotation. It would approach Lamar County before 11:30 p.m. Add another hour or so for Tuscaloosa, another two hours for Birmingham. We will have to watch these storms.
The airmass is very unstable across North Mississippi and North Alabama. These storms should hold together and will produce severe weather along their entire tracks.
At some point, a powerful squall line will form and rush eastward. It will have a high probability of producing significant wind damage all the way across the area during the hours after midnight.
A tornado watch remains in effect for North and Central Alabama until 2 a.m.
