...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected on Saturday.

...Ohio Valley and central Appalachians...

The synoptic upper low centered over the OH Valley Saturday morning
will move generally northeast, reaching the Northeast U.S. Saturday
night. A dry continental polar airmass will reside across the OH
Valley. Weak instability resulting from surface heating, cold air
aloft and mid-level forcing for ascent attending vorticity maxima
rotating through the upper low circulation will contribute to a few
mostly snow showers. However, it appears the convective layer depth
and degree of instability will remain insufficient for
thunderstorms.
