The above composite radar image shows a line of intense thunderstorms (some severe) continuing to advance Eastward across the southeast U.S. this morning. This activity originated over Kansas and Oklahoma yesterday evening.
Tornado Watches are currently in effect along and ahead of the line:
...and the threat of severe weather will spread into the remainder of the southeast as the day wears on. Below is the latest severe weather outlook for today from the SPC:
Severe thunderstorms are possible anywhere within the green outlined area, with the highest threat (including possibly damaging tornadoes) within the red outlined area from central and southern Mississippi into much of Alabama. I wouldn't be surprised to see this higher threat area expanded Eastward into Georgia and/or southeast Tennessee in the updates from the SPC later today.
Residents of the the severe weather outlook areas should remain alert today and be prepared to seek shelter as threatening weather approaches. Large hail, damaging winds and tornadoes are likely with severe storms in the region today. There is also the potential for one or more long track, damaging tornadoes, particularly across the area outlined in red in the image above.
