Areas affected...far western KY

Concerning...Severe potential...Watch unlikely=20

Valid 090238Z - 090445Z

Probability of Watch Issuance...20 percent

SUMMARY...Some risk for damaging gusts may develop over mainly
portions of far western KY through this evening.

DISCUSSION...Radar mosaic indicates storms have intensified during
the past 30-60 minutes across far southeast MO.  Surface analysis
shows temperatures/dewpoints have warmed into the lower 60s over
northern parts of western TN and into the mid-upper 50s at Paducah.=20
The northward theta-e advection within the arching warm frontal zone
over western KY/middle TN has led to weak buoyancy developing across
the lower OH Valley.  Around 250-500 J/kg MUCAPE is located across
this region according to RAP 0-hr forecast soundings and objective
analysis.  Given the veering and very strong flow fields from just
above the surface through the mid troposphere, it seems this
evolving line segment near the MS River may yield a risk for
damaging gusts over the next couple of hours across western KY.
