AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
638 PM EST Wed Dec 3 2025

.SYNOPSIS...
Cool weather continues into next week. Chances are increasing in a
period of accumulating snow Friday morning into Friday afternoon.
Precipitation chances over to a wintry mix or all rain by Friday
afternoon into Friday evening before ending. An unsettled pattern
continues through Monday with a low chance for light additional
precipitation.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
As of 305 PM EST Wednesday...

Key Messages:

- Below average temperatures with sunny and dry conditions are expected
  today.

- Mostly clear and cold tonight.

A strong area of low pressure continues to move offshore from the
coast of Maine. Meanwhile, a ~1024mb high pressure was centered over
the TN Valley. Temperatures as of 140 PM were in the mid 40s for
most with afternoon highs a degree or two higher. High pressure
continues to build in from the W through tonight. With high pressure
continuing to build in overnight, calm winds, and clear skies, temps
are expected to fall into the mid-upper 20s inland and around 30F
along the coast. A few rural inland locations may drop into the
lower 20s tonight.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY NIGHT/...
As of 305 PM EST Wednesday...

Key Messages:

- Dry weather continues Thursday and Thursday night.

- There is increasing potential for light to moderate snow
  changing to a wintry mix Friday into Friday night.

The first area of high pressure slides offshore Thursday, resulting
in moderating temperatures with highs in the mid-upper 40s N to
lower 50s S. A dry cold front drops through the area later Thursday
afternoon and evening with a 1028-1030mb high pressure building to
the N Thursday night into early Friday. It will be cold Thursday
night into early Friday morning with overnight lows in the lower 20s
NW to lower 30s SE. The flow aloft will generally be zonal to begin
the day, but will amplify to some extent as a trough digs into the
upper Midwest. At the surface, high pressure gradually retreats to
the NE Friday. A powerful upper jet upwards of 180kt is progged to
extend from the northern Mid-Atlantic to southern New England. A
wave of low pressure is expected to develop along the stationary
front Friday beneath the RRQ of the upper jet with some assistance
from a sheared shortwave trough from 700-500mb.

There is increasing potential for a period of snow transitioning to
a wintry mix or rain Friday across most of the area, remaining
wintry longer to the NW, and mainly rain for far SE VA and most of
NE NC. The 12z EPS increased probs for >1" of snow to 70-100% for
most of the area (assuming a 10:1 ratio and idealized accumulation),
with probs dropping sharply for >3" to only around 10%. The 12z GEFS
remains lower, but has trended up to 30-60%. As moisture shallows
late Friday afternoon into Friday night, precipitation could change
to light freezing rain from central VA to the Piedmont where light
ice accretion is possible. Additionally, there is some potential for
light freezing drizzle inland continuing through much of Friday
night. Confidence is high in a light accumulation of snow with 1-2"
possible across a portion of the area (likely central VA). However,
confidence is low in exact freezing rain totals which will be highly
dependent upon how much moisture is available with this system. Both
the NAM and GFS forecast soundings showed drying conditions in the
DGZ from Friday afternoon into Friday night. This is key as it
essentially makes the difference between staying all snow and having
higher snowfall totals or transitioning to freezing drizzle or light
freezing rain. It`s worth noting that the NBM 90th percentile for
snow has increased to 3-4" across the NW half of the FA with the NBM
90th percentile for freezing rain showing the potential for up to
around 0.25" of freezing rain across south central and southern VA.
If moisture is greater than currently modeled, snowfall totals could
be closer to the high end potential from NBM 90th with minimal
freezing rain. Conversely, if the dry air in the DGZ is realized and
occurs earlier in the day on Friday, freezing rain totals could
increase with snowfall totals decreasing.

Temperatures will potentially be quite cold for early December
during the day Friday. With morning temps in the 20s across much of
the are Friday morning, snow will likely have no issue accumulating,
including untreated roads. As such, it will not take a lot of snow
to cause slippery road conditions. Additionally, temps may struggle
to get above freezing Friday across the Piedmont with mid 30s along
the I-95 corridor. The warmest temps Friday will likely be along the
coast where mid-upper 40s are possible. Any slush or water on the
roadways will likely refreeze Friday night given lows in the 20s
expected (away from the coast).

Saturday will be mostly dry and cool with highs in the mid-upper 40s
(most in the mid 40s) and lows Saturday night in the 20s. A few
light showers are possible across far SE VA/NE NC Saturday, however,
any precip that falls should be plain rain (as opposed to wintry
precip).

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 305 PM EST Wednesday...

- Below average temperatures continue into early next week.

- There is a low chance for additional precipitation Sunday
  night into Monday as a surface low develops offshore.

The general model consensus is for primarily dry conditions on
Sunday apart from a slight chance for a few light showers across far
SE VA/NE NC. Uncertainty increases for Monday with a range of
possibilities on the table. The ensembles show a shortwave trough
moving across the area on Monday underneath a longwave trough across
the East Coast. The ensemble clusters show a surface low developing
in response to this shortwave off the Southeast coast. While this
solution taken verbatim would suggest minimal (if any) precip for
the local area, any shift NW could quickly change the setup from an
offshore low with little to no impact to an impactful winter system.
A few things that are worth noting are that the NAO remains
weakly negative into Monday while the PNA quickly goes from
negative on Saturday to positive on Monday. These
teleconnections are favorable for cold air across the local
area (NBM highs for Monday are in the mid- upper 30s for most
and low-mid 40s across SE VA/NE NC). Therefore the cold air will
be in place. The question that will need to be ironed out with
ensemble trends in the upcoming days is, does the low remain
suppressed (like most models currently show) or does it continue
to trend NW?

Beyond Monday, uncertainty remains high with respect to the
forecast. However, cool weather likely continues with perhaps
another chance for precipitation in the mid to late week period.

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
As of 630 PM EST Wednesday...

High pressure remains in place overnight, well out ahead of a
cold front approaching from the NW. Mainly clear overnight (just
some high clouds) with light winds. VFR conditions continue
Thursday, with a dry cold front crossing the area later in the
morning through the early aftn, bringing just SCT-BKN mid/high
clouds. Winds shift to the NW and become a bit breezy across the
eastern shore with gusts up to ~20kt at SBY by aftn. Elsewhere,
winds will generally be 10 kt or less.

Outlook: Low pressure will bring degraded flight conditions
Friday into Friday night with mainly snow turning to a wintry
mix for the northern terminals and -RA/SN changing to mainly
rain for the southeastern terminals. Regardless of p-type, a
prolonged period with flight restrictions down to IFR thresholds
or lower is expected. Mainly dry Sat-Sun, though some low
chances for precipitation and the potential for periodic flight
restrictions may linger in the SE.

.MARINE...
As of 250 PM EST Wednesday...

Key Messages:

- Another round of elevated winds is expected late Thursday into
  Friday.

High pressure is sliding in from the west this afternoon, leading to
diminishing winds that are generally out of the north with some
variation between NW and NE. Latest obs show 5-10kt. Seas have come
down as well with buoy obs indicating ~3ft N of the the VA/NC border
and closer to 4ft off the NC coast. Winds remain fairly light
tonight as they gradually turn toward the SW. Winds turn back to the
NW behind another cold front by Thurs evening, briefly increasing to
15-20kt with gusts to ~25kt in the bay and coastal waters Thursday
evening/night. Opted to hold off on another round of SCAs for this
surge given that it is on the lower end of criteria, relatively
brief, and over 24 hours out at this point. By early Friday morning,
winds should be diminished to 10-15kt and turning to the NE. Low
pressure develops along the coast on Friday, but not expecting
elevated winds at this point. Even probs of 18kt winds are limited
to ~20% over coastal waters. This system will bring rainfall that
could reduce visibility and even the potential for some snow across
the upper/middle bay. Benign marine conditions expected through the
weekend.

Seas will be 2-3ft tonight and waves around 1ft in the bay/rivers.
When the winds pick up Thurs evening/night, seas will increase to 3-
4ft with 5ft out near 20nm. Waves in the bay will be around 3ft with
perhaps a brief period of 4ft when winds peak. Seas and waves
diminish again Friday and stay below SCA thresholds through the
weekend.
