   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.
