   Concerning...Severe Thunderstorm Watch 375...

   Valid 222034Z - 222200Z

   The severe weather threat for Severe Thunderstorm Watch 375
   continues.

   SUMMARY...Thunderstorm clusters may pose an increasing risk for
   damaging winds across portions of northern and central Virginia over
   the next 1-2 hours.

   DISCUSSION...Thunderstorm clusters moving over the Blue Ridge
   Mountains and into northern/central VA may pose an increasing risk
   for damaging wind gusts the next 1-2 hours. These storms will
   continue tracking east/northeast into a hot airmass with steep 0-3
   km lapse rates around 7.5-8.5 C/km. Sufficient instability
   (1000-1500 J/kg MLCAPE) and 30 kt effective shear magnitudes should
   support at least transient storm organization and some increase in
   intensity in the short term.
