Surface analysis (above) from 20Z indicates southeasterly flow over much of the Florida panhandle, southern Alabama and Mississippi. The winds veer with height to nearly out of the west at 300 mb according to the SPC mesoanalysis. The CAPE doesn't seem to be as strong as it was earlier over southern Louisiana. However, the storm relative helicity values are pushing 400 ahead of the line of thunderstorms based on the SPC mesoanalysis. The SPC is maintaining a slight risk of severe weather for extreme southern Mississippi and Alabama, and the Florida panhandle.
The shortwave trough and surface front is expected to continue to move towards the east and maintain the line of activity. The instability and shear look to continue this afternoon and provide a risk of mostly damaging winds, but I would not rule out a tornado or two. The SPC is counting on the severe threat to diminish by 6Z (midnight CST) according to their latest discussion.
I'll try to keep an eye on this during the afternoon and evening. Keep tabs on my Twitter feed.
