Mesoscale Discussion 0532
NWS Storm Prediction Center Norman OK
0209 PM CDT Sat May 04 2019
Areas affected...southwestern Alabama and western parts of the
Florida Panhandle vicinity
Concerning...Severe Thunderstorm Watch 130...
Valid 041909Z - 042115Z
The severe weather threat for Severe Thunderstorm Watch 130
continues.
SUMMARY...Local risk for severe storms continues in/near WW 190.
DISCUSSION...Latest radar loop shows a still-loosely organized band
of storms moving across the southeastern Mississippi/southwestern
Alabama border, while other/more cellular storms increase in
coverage in a "warm-advection wing" extending east-southeast across
southwest Alabama and western portions of the Florida Panhandle.
With a moist/unstable airmass residing in/near the WW area, expect
storms to continue spreading across the WW area.
Slight backing of the surface wind field persists near the Gulf
Coast, which continues to modestly enhance low-level shear. This
suggests relatively greater -- but still limited -- risk for a brief
tornado over southern portions of the watch area. Otherwise,
moderate/roughly unidirectional west-southwesterly flow across much
of the area supports locally damaging winds as the main severe risk
-- especially with the linear band of storms.
