...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE OHIO VALLEY AND CENTRAL APPALACHIANS...

...SUMMARY...
Isolated severe storms will be possible on Wednesday across the Ohio
Valley and central Appalachians.

...Ohio Valley/Central Appalachians...
An upper-level trough will move eastward across the Ohio and
Tennessee Valleys on Wednesday. At the surface, a low will move
eastward across the lower Great Lakes, as a cold front advances
east-southeastward through the Ohio and Tennessee Valleys. Ahead of
the front, surface dewpoints in the lower to mid 50s F will
contribute to weak destabilization by afternoon. MLCAPE near the
instability axis is forecast to peak around 500 J/kg with 0-6 km
shear in the 25 to 35 knot range. This should support a marginal
severe threat during the afternoon as low-level lapse rates become
steep. A few isolated severe wind gusts will be possible.
