Areas affected...Eastern OH...WV Panhandle...Western PA

Concerning...Severe Thunderstorm Watch 128...

Valid 052246Z - 060015Z

The severe weather threat for Severe Thunderstorm Watch 128
continues.

SUMMARY...Gusty winds will continue to be observed with convection
this evening.

DISCUSSION...Seasonally warm surface temperatures (low-mid 80s) have
contributed to very steep low-level lapse rates across the upper OH
Valley. Thermodynamic profiles continue to favor gusty downdrafts
given the 30F surface temp/dew point spreads. While SBCAPE is
somewhat marginal, strong shear and PWs in excess of 1 inch suggest
locally strong downbursts may continue into the early evening hours
before temperatures begin to cool. Some of this activity may spread
into western PA before weakening.
