Areas affected...northeastern Mississippi eastward/southeastward to
eastern Georgia

Concerning...Severe potential...Watch possible=20

Valid 031750Z - 031945Z

Probability of Watch Issuance...40 percent

SUMMARY...Potential for strong wind gusts locally -- and possibly a
few gusts at/near severe levels -- will continue to slowly increase
this afternoon. Risk may warrant consideration of a WW issuance in
the next hour or so.

DISCUSSION...Latest radar loop shows some redevelopment of storms
ongoing, near convective outflow on the southwestern flank of the
remnant MCS over the Tennessee Valley. Diurnal heating -- and thus destabilization -- has been somewhat muted from northern Alabama
eastward due to cloud cover. However, mixed-layer CAPE now near
1000 J/kg (and greater to the west across northern Mississippi), has
begun fueling new storm development near the outflow boundary
extending roughly west-to-east across this area.

Moderate northwesterly flow aloft is indicated across the region,
which is sufficient for some storm organization, and potential for upscale/linear growth of storms with time. Any risk for damaging
wind gusts would likely remain quite isolated, until and unless some
linear organization occurs. We will continue to monitor convective
evolution for signs of such an increase, which would then
necessitate more serious WW consideration.
