Areas affected...western Tennessee...northern Mississippi

Concerning...Severe Thunderstorm Watch 535...

Valid 211938Z - 212045Z

The severe weather threat for Severe Thunderstorm Watch 535
continues.

SUMMARY...Damaging wind threat continues within WW535.

DISCUSSION...A line of storms moving across western Tennessee
continues to show intensification. The line maintains a well defined
bowing segment and rear inflow jet with the apex of the bow moving
into Hardeman and Madison counties in Tennessee. A recent report of
a 54 mph gusts was noted from the Memphis International Airport as
the storms moved through the Memphis metro. Radar continues to show
60-70 kt flow just off the surface. Ahead of the line, daytime
heating has allowed for temperatures in the mid to upper 80s (some
90s across northern Alabama) and MLCAPE around 2000 J/kg. Damaging
winds are expected to continue as the line advances eastward into
unstable air downstream.
