Mesoscale Discussion 0100
NWS Storm Prediction Center Norman OK
0830 PM CST Sat Jan 21 2017
Areas affected...A small portion of southeast Mississippi into
central and southern Alabama and parts of the Florida Panhandle
Concerning...Tornado Watch 17...
Valid 220230Z - 220400Z
The severe weather threat for Tornado Watch 17 continues.
SUMMARY...Severe/tornado risk continues to expand across Tornado
Watch 17.
DISCUSSION...As the west-to-east surface warm front continues to
shift slowly north across Mobile Bay and the Florida Panhandle, a
very favorable supercell environment (as revealed by the 22/00Z LIX
RAOB, and area VWPs) continues to support an increase in coverage
and intensity of severe storms across the region. While storms
continue to increase across the southern half of Mississippi which
will eventually spread into WW 17, the more immediate threat exists
with cells farther south, shifting east-northeast out of the Florida
Panhandle into adjacent southern Alabama. The most significant
storm is currently straddling the Escambia AL/Escambia FL county
line, where a potentially tornadic circulation is evident on radar.
Expect convective coverage to increase northward across the watch
over the next couple of hours, along with continued severe/tornado
potential.
