   Areas affected...portions of northeast Virginia

   Concerning...Severe Thunderstorm Watch 234...236...

   Valid 202314Z - 202345Z

   The severe weather threat for Severe Thunderstorm Watch 234, 236
   continues.

   SUMMARY...A damaging gust or episode of hail may occur in the next
   1-2 hours.

   DISCUSSION...A cluster of storms continues to track northeast toward
   a localized a pristine airmass that has yet to be overturned by
   convection (e.g. the Grant County Airport ASOS showing 87 F surface
   temperatures). As such, storm cores in the area may remain strong
   enough over the next 1-2 hours to produce a damaging gust or
   instance of hail as they approach this reservoir of potentially
   unstable air. Thereafter, the severe threat should continue to
   diminish with time.
