Areas affected...extreme southeast KY...portions of eastern TN

Concerning...Severe potential...Watch possible

Valid 261843Z - 261945Z

Probability of Watch Issuance...40 percent

SUMMARY...An isolated risk for 40-55 mph gusts capable of pockets of
wind damage probably exists near and east of the I-75 corridor in
southeast KY near the TN/KY border and for portions of eastern TN.
A severe thunderstorm watch is being considered.

DISCUSSION...Radar mosaic shows a mature squall line over KY with
the most intense portion of the convective line over central KY.  A
considerable amount of pre-squall line convection has limited
destabilization over eastern KY where temperatures are steady in the
lower 70s degrees F.  Farther south near the TN/KY border towards
the Cumberland Gap, a west-east broken cluster of thunderstorms has
served as a northern delimiter for where the airmass is moderately
unstable.  South of this convection, temperatures are in the
middle-upper 80s with lower 70s dewpoints.  As the larger-scale
convective complex moves east across northern portions of TN and KY,
it appears a relatively narrow corridor of greater potential for
strong gusts (40-55 mph) may exist near the TN/KY border into
eastern portions of TN.
