Weather Blog: Severe weather threat for Monday

MONTGOMERY, AL (WSFA) - It's an active Monday morning across central and south Alabama. Thunderstorms have developed along and ahead of a frontal boundary and are overspreading the area. The threat for severe weather has already opened up for parts of the area and should continue into the afternoon. Let's dive right in...

TODAY: A Tornado Watch is in effect for roughly the western half of Alabama until Noon. It's is entirely possible an additional watch will be necessary for eastern Alabama later today. A frontal boundary is indicated by a line of thunderstorms across far west Alabama. That line poses a threat for mainly damaging winds as it plows eastward. Out ahead of that line, individual thunderstorms have shown a tendency to rotate in a highly sheared environment. These cells out ahead of the line pose the greatest risk for isolated tornadoes.

Speaking of that highly sheared environment, that will only go so far this morning. We need instability too, which we have, but in limited quantities. The best instability will exist across south Alabama. As a result, our southern counties may stand the best chance for Warnings as storms will have maximum opportunity to thrive. Farther north, we still can't rule out a damaging wind gust or isolated tornado considering just how strong that shear is. The threat for severe weather shifts into the eastern half of Alabama by afternoon and should be done after roughly 6pm based on current trends.

Not to be ignored will be the possibility for additional heavy rain which could generate more flooding concerns. We think overall rainfall totals should not exceed 1-2", but will need to be watched. We'll dry out overnight into Tuesday before more rain develops Tuesday night and Wednesday. Cooler air finally makes a cameo by the end of the week into the weekend for the start of the new year.
