Areas affected...Part southern Indiana...north-central
Kentucky...and extreme southwest Ohio

Concerning...Severe potential...Watch unlikely

Valid 291123Z - 291430Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated strong to locally severe wind gusts will be
possible through about mid morning across far south-central and
southeast Indiana, north-central Kentucky, and extreme southwest
Ohio.

DISCUSSION...Early morning trends in mosaic radar imagery showed a
bowing line of storms tracking to the east at 35-40 kt through far
south-central IN.  This activity appears to be elevated, generally
well north of a convective outflow boundary which extended from
central WV to JKL to 40 S LEX to approximately 25 SW SDF.  However,
surface and near-surface winds per area VADs across the lower TN
Valley into western part of KY have backed to southerly, with
surface winds north of the outflow (at FFT and LEX) having become
southerly with a little increase in low-level moisture.  This trend
has resulted in some destabilization with northward extent and in
advance of the bowing line of storms.  Given some destabilization
this morning and strong winds in the low levels (45-50 kt per VAD at
LVX WSR-88D), locally strong to severe wind gusts cannot be ruled
out across the discussion area through 14Z.
