Areas affected...eastern Ohio...western Pennsylvania...far West
Virginia...far southwestern New York

Concerning...Severe Thunderstorm Watch 401...

Valid 092051Z - 092145Z

The severe weather threat for Severe Thunderstorm Watch 401
continues.

SUMMARY...Severe threat continues within WW401.

DISCUSSION...Several broken segments of multi-cell clusters continue
across WW401. A few instances of wind damage have been reported
across northern PA and southern OH. A few cells have initiated out
head of the main clusters but have struggle to maintain intensity.
Ahead of the line, temperatures continue to warm, with MLCAPE around
500 J/kg slowly advecting northward across New York state. As
forcing for ascent continues to increase with the approaching wave,
thunderstorm coverage will continue to increase. Damaging wind and
severe hail continue to be a possibility with stronger cells.
