Areas affected…from central Louisiana east into southern Alabama

Concerning…Severe Thunderstorm Watch 225…226…

Valid 100441Z – 100545Z

The severe weather threat for Severe Thunderstorm Watch 225, 226
continues.

SUMMARY…Clusters of strong/severe storms — capable of producing
damaging winds and hail — will continue moving eastward across
portions of WW 225 and 226. New WW may be required to extend a bit
farther south into parts of southeastern Louisiana.

DISCUSSION…Widespread thunderstorms currently extend from
east-central/southeastern Mississippi west-southwestward to
southwestern Louisiana. Meanwhile, a weakening band of storms is
moving into southwestern Georgia — but with new storm development
over southern Alabama along remnant outflow.

Overall, a very unstable (averaging 3000 J/kg mixed-layer CAPE)
persists across the central Gulf Coast region south of areas that
have been convectively overturned previously. This suggests that
storms should persist well into the overnight, spreading eastward
out of Mississippi into Alabama, and perhaps expanding a bit
southward into parts of southeastern Louisiana. Locally damaging
wind gusts and hail can be expected across this area, and a new WW
south of the existing watches may be needed in the short term, to
cover the southern extent of this risk area.
