   Areas affected...eastern West Virginia and northern Virginia into
   the DelMarVa

   Concerning...Heavy snow 

   Valid 060712Z - 061215Z

   SUMMARY...1+ inch per hour snowfall rates are expected early this
   morning.

   DISCUSSION...A band of moderate to heavy snow has developed across
   northern Virginia amid strong isentropic ascent and frontogenesis
   early this morning in response to a strengthening low-level jet.
   Evidence of this can be seen on the FCX VWP where 1.5 km winds have
   strengthened from 50 to 65 knots in the last 90 minutes.   These
   conditions favorable for heavy snowfall are expected to shift east
   through the early morning hours with the expanding low-level jet,
   and heavier snowfall rates expected to impact the DelMarVa within
   the next few hours. Maximum snowfall rates of 1 to 1.5 inches per
   hour are expected.
