The NWS has issued tornado warnings for Greene and Pickens counties. Storms are showing some rotation, and given the tornado damage near Meridian, MS earlier, they are not taking chances.

An area of strong to severe thunderstorms is approaching west Alabama from Mississippi right now. There is fairly significant wind shear in place over Alabama, and that will help the storms keep going, and may cause some storm rotation. A tornado watch is in effect for areas from Birmingham and... Continue reading

Some of the computer models indicated air below 10 degrees coming into Alabama already this winter (and it didn't even come close to happening...it was in December), but this time all 3 major computer models have general agreement and they are consistently showing a blast of Arctic air coming into...

In a December that has become characterized by an active jet stream that stays just to our north, another upper-level wave will approach on Saturday.

SPC has moved their slight risk for severe weather north to include BHM, probably due to the models' more aggressive surge of moist air northward than yesterday. Some of the ingredients are there for severe thunderstorms. The air will be slightly unstable as mild, humid air tries to come in... Continue reading
