Area Forecast Discussion
National Weather Service Blacksburg VA
203 PM EST Mon Dec 8 2025

.SYNOPSIS...
A disturbance will pass across the region today, resulting in
widespread snow. Dry and seasonable conditions return Tuesday
and Wednesday, with some upslope showers/snow showers possible
again by Thursday. A much colder airmass arrives late week and
into the weekend, resulting in well below normal cold
temperatures over the Mid- Atlantic.

&&

.NEAR TERM /THROUGH TUESDAY/...
As of 130 PM EST Monday...

Key Messages:

1) Widespread snow accumulations expected through this afternoon
into early evening, with slick and hazardous travel likely.

2) Very cold temperatures expected tonight and possible black ice.

Key Message 1:

Wave of moderate snow has moved into the Piedmont this afternoon and
so far have had multiple reports near 3 inches of accumulation so
far. Morning upper air sounding showed a decently steep lapse rate
within the dendritic growth zone so not surprised if heavier
areas/bands could result in a fairly quick snow rate. Coverage has
currently filled in some from the west closer to the main upper vort
max and this could drop another 1-2 inches across portions of the
area before all is said and done. CAMs support coverage largely
diminishing by about 5-7 PM this evening. Have continued the current
Winter Storm Warning and Winter Weather Advisory.

Key Message 2:

Confidence is increasing in the threat of black ice for Tuesday
morning as colder temperatures are ushered in from the NE from the
building CAD wedge. Much of the CWA has been in the low 30s but the
20s have started to impinge upon the far north and a decreasing
trend should continue from now into the overnight. Much of the area
is progged to be in the teens near the morning commute time so roads
could still be hazardous if any slush or remnant moisture is left on
the surface.

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
As of 115 PM EST MONDAY...

Key Messages:

1) Quiet and cool

2) Quick moving front brings upslope snow Wednesday and Thursday

High pressure overhead on Tuesday and early Wednesday will keep
conditions calm and prevent any unsettled weather. Temps will reach
into the 40s and 50s during the day to help thaw out after some
extreme cold and snow earlier in the week. A progressive low
pressure system will be making its way through the upper Midwest,
near the Canadian border. A front will veer our winds to the
west/northwest, bringing upslope against the mountains late on
Wednesday. Upslope showers will begin as rain, but turn over to snow
overnight Wednesday into Thursday as colder air takes hold. The
upslope snow will persist Thursday the northwest flow continues, but
coverage will likely recede towards West Virginia. An inch or two in
the higher elevations of Greenbrier County WV could stick, with
generally less than an inch in other parts of the mountains.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
As of 140 PM EST MONDAY...

Key Messages:

1) Upslope showers taper Friday

2) Weekend system should have broader impacts than just upslope

Northwest flow will continue to weaken Friday, and with it, cut off
upslope snow effects in the western mountains.

Another low pressure system moving near the US/Canada border above
the Great Lakes will bring a front through the eastern seaboard over
the weekend. A deepening mid-level trough will accompany this front,
allowing a greater impact than the upslope showers of the previous
system. Precipitation will likely stretch east of the Blue Ridge.
Given the time of year, and the general pattern of the previous week
or so, the forecast will monitor snow and ice chances closely for
next weekend. For now, just trying to nail down timing, as this is
about a 24 hour discrepancy in the front`s timing from guidance this
time yesterday. Once we feel confident on when the front will
impact us, the forecast can focus on what those impacts will be.

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
As of 115 PM EST Monday...

Mainly IFR/LIFR cigs and reduced vsbys down to 1/4 SM through
the afternoon with areas of snow. Snow should taper off after
about 00-02z though low cigs should remain through most of the
overnight (vsbys should improve somewhat into 3-5 SM range).
Cigs should improve and scatter out starting around 14/15z for
most sites though could linger farther west. Initial winds
mostly around 10 kts or less out of the NE, becoming light to
calm overnight, then south to SW 7 kts or less for Tuesday.

.EXTENDED AVIATON OUTLOOK...

VFR conditions are increasingly likely to return for Tuesday,
remaining through Wednesday. Sub-VFR conditions return by
Thursday for the mountains with upslope clouds and snow showers.
