[html]MD 1518 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR EAST-CENTRAL AND SOUTHEASTERN ALABAMA...NORTHERN PORTIONS OF THE FLORIDA PANHANDLE...AND PARTS OF CENTRAL AND SOUTHERN GEORGIA
Mesoscale Discussion 1518
NWS Storm Prediction Center Norman OK
0114 PM CDT Tue Jul 19 2022
Areas affected...east-central and southeastern Alabama...northern
portions of the Florida Panhandle...and parts of central and
southern Georgia
Concerning...Severe potential...Watch unlikely
Valid 191814Z - 192015Z
Probability of Watch Issuance...5 percent
SUMMARY...Scattered to numerous thunderstorms will continue
developing across parts of the Southeast, with locally gusty winds
-- capable of producing tree/branch damage -- possible.
DISCUSSION...Latest radar and visible satellite loops show storms
increasing in coverage across portions of Alabama and Georgia, and
vicinity, to the south and southeast of a short-wave trough shifting
southeastward across the southern Appalachians. The storms are
evolving within a very moist (mid 70s dewpoints) airmass, where
insolation has helped to push mixed-layer CAPE values into the 2000
to 3000 J/kg range.
As storms continue to evolve, some organization is being observed --
aided by moderate/unidirectional westerly flow indicated across the
region on the southern periphery of the upper trough. As outflow
boundaries merge favoring new/possibly vigorous updraft growth
locally, gusty winds -- capable of minor damage -- may occur
locally. However, given expectations that such stronger gusts will
remain sparse/sporadic, and largely below official severe levels, WW
issuance is not likely to be required.
