Areas affected...southern Virginia and far northern North Carolina
Mountains
Concerning...Winter mixed precipitation=20
Valid 060744Z - 061245Z
SUMMARY...Moderate freezing rain is expected to expand across
southern Virginia and the northern North Carolina mountains early
this morning.
DISCUSSION...Temperatures are in the upper 20s to near 30 across
much of southern Virginia this morning. Some snow is occurring
across central Virginia where the thermodynamic column remains below
freezing, but the 0C 700mb isotherm, currently located near or just
south of Roanoke at 07Z will expand north amid strong warm air
advection and a strengthening low-level jet. This will result in
sleet or freezing rain across much of southern Virginia within the
next few hours. In addition, strong isentropic lift and additional
upper-level ascent will support moderate precipitation across this
region for the next 6 hours with significant ice accretion likely
for much of the period.=20
Moderating temperatures may limit ice accumulation across far
southern Virginia with the greatest accumulation from near Roanoke
to Lynchburg to Lexington where upper 20s temperatures are most
likely to persist.
