MD 0019 CONCERNING HEAVY SNOW FOR EASTERN WEST VIRGINIA AND NORTHERN VIRGINIA INTO THE DELMARVA


Mesoscale Discussion 0019
NWS Storm Prediction Center Norman OK
0112 AM CST Mon Jan 06 2025

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.
