MD 1730 CONCERNING TORNADO WATCH 497... FOR PARTS OF SOUTHERN ALABAMA AND INTO WESTERN PORTIONS OF THE FLORIDA PANHANDLE

Mesoscale Discussion 1730
NWS Storm Prediction Center Norman OK
0709 AM CDT Sat Oct 10 2020

Areas affected...parts of southern Alabama and into western portions
of the Florida Panhandle

Concerning...Tornado Watch 497...

Valid 101209Z - 101415Z

The severe weather threat for Tornado Watch 497 continues.

SUMMARY...Risk for brief tornadoes continues across Tornado Watch
497, in conjunction with Tropical Storm Delta.

DISCUSSION...Latest radar loop shows the center of Tropical Storm
Delta near the intersection of the Arkansas/Louisiana/Mississippi
borders.  A primary band of convection east/southeast of Delta's
center continues advancing eastward across southwestern Alabama,
while individual convective elements move quickly northward.

Within this band of low-topped convection, occasional cells have
exhibited low-level rotation, with at least one confirmed tornado
earlier this morning.  While a moist boundary layer resides ahead of
the convective band, CAPE remains limited, particularly with
northward extent into central Alabama.  Still, low-level flow
veering/increasing with height is yielding shear quite favorable for
occasional low-level rotation within sustained updrafts.  As such,
the risk for brief tornadoes will continue across the watch area.
