Areas affected...Western and Middle Tennessee

Concerning...Severe Thunderstorm Watch 603...

Valid 201026Z - 201130Z

The severe weather threat for Severe Thunderstorm Watch 603
continues.

SUMMARY...Severe Thunderstorm Watch 603 will expire at 11z, and a
new watch is not expected.

DISCUSSION...Widespread thunderstorms and stratiform precipitation
continue across portions of western and Middle Tennessee at 1020z.
Substantial convective overturning and weakening low-level warm
advection have led to generally diminished intensities over most of
the remaining watch area since 09z. Although an occasionally
stronger storm will remain possible over the next 1-2 hours over
western and Middle TN in proximity to a modestly veering low-level
jet, current and expected short-term convective trends should
preclude the need for a new watch.
