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

    Concerning...Heavy snow=20

    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.
