Concerning...Severe Thunderstorm Watch 226...

Valid 270306Z - 270430Z

The severe weather threat for Severe Thunderstorm Watch 226
continues.

SUMMARY...Although a locally strong wind gust cannot be ruled out
across and just east of the remaining portion of WW 226 in western
Tennessee and western Kentucky, the overall severe-weather threat
will continue to diminish through the late evening.  A new severe
thunderstorm watch issuance is not needed east of WW 226.

DISCUSSION...Trends in mosaic radar imagery this evening showed a
long-lived, forward-propagating MCS had moved into western portions
of KY and TN during the latter part of the evening.  Short-term
guidance suggests this band of storms should reach central KY and
middle TN after midnight.  However, an overall weakening trend, as
already noted in much of the leading band of storms, given the
deceleration in forward speed and weakening storm intensities, will
persist and preclude the need for a new watch.  The further increase
in surface-based inhibition and greater boundary-layer stability
with eastward extent are key factors limiting the severity of storms
into the early overnight.
