   Areas affected...western and central PA

   Concerning...Severe potential...Watch possible 

   Valid 272034Z - 272200Z

   Probability of Watch Issuance...60 percent

   SUMMARY...A band of developing strong to severe thunderstorms may
   continue to pose a risk for damaging gusts across western and
   central PA over the next few hours.

   DISCUSSION...Radar mosaic shows a band of storms developing from
   near Youngstown, OH eastward into northwestern PA.  The Youngstown,
   OH ASOS recently measured a 52-kt gust at 423pm EDT.  KPBZ VAD data
   has shown a slight intensification of the wind profile around 3km
   ARL during the past 1-2 hours (30 to 40 kt).  Given a very
   moist/warm boundary layer downstream of the ongoing activity
   (surface dewpoints in the lower 70s F), it seems plausible at least
   an isolated risk for severe gusts may continue for the next few
   hours.
