AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
642 PM EST Thu Jan 29 2026

.WHAT HAS CHANGED...
Minor changes to storm total snowfall forecast, with amounts
decreasing across the northern half of the area. Blizzard
wording has been added to the Winter Storm Watch along the
coast. A Cold Weather Advisory has been issued tonight for the
Maryland Eastern Shore and Accomack County, VA. An Extreme Cold
Watch has been issued for the entire forecast area Saturday
night into Sunday.

&&

.KEY MESSAGES...
1) High confidence that a strong winter storm impacts the region
Friday night into Sunday. Significant accumulating snowfall, blowing
and drifting snow due to strong winds, coastal flooding, and
significant marine impacts are expected. The highest confidence is
across south and southeastern portions of the area. There will
likely be a very sharp gradient in total snowfall amounts, roughly
along the US-360 corridor (potentially through the Richmond Metro).

2) A quick burst of light to moderate snow is possible Friday
afternoon and evening ahead of the main winter storm, especially
across portions of central and south central Virginia. Due to the
very cold temperatures, any snow could quickly accumulate on
surfaces, including roadways. This is a low confidence, but
potentially high impact event.

3) Well below normal temperatures remain through early next week,
keeping localized impacts (i.e icy roads) in place through the
weekend. The coldest air wind chills are expected Saturday night
into Sunday morning and an Extreme Cold Watch has been issued for
the entire forecast area. A Cold Weather Advisory is in effect
tonight for portions of the Maryland and Virginia Eastern Shore.

.DISCUSSION...
As of 315 PM EST Thursday...

KEY MESSAGE 1...High confidence that a strong winter storm impacts
the region Friday night into Sunday. Significant accumulating
snowfall, blowing and drifting snow due to strong winds, coastal
flooding, and significant marine impacts are expected. The highest
confidence is across south and southeastern portions of the area.
There will likely be a very sharp gradient in total snowfall
amounts, roughly along the US-360 corridor (potentially through the
Richmond Metro).

Disagreement still remains higher than what is typically seen during
this time range (especially on the NW side) amongst the
deterministic and ensemble guidance in regards to total snow
amounts/locations of the higher snow amounts across the area. The
main mode of disagreement continues to be the battle zone between
drier air from the N/NW associated with a very strong area of high
pressure (~1045 mb) over the Plains, and an intense low pressure
system developing off the SE coast late Friday night/Saturday. The
disagreements in regards to snow amounts can be seen well in the
probabilistic snowfall range amounts. If we use Richmond as an
example, the 25th percentile shows 1" and the 75th percentile shows
8". For Norfolk, the ranges are a bit "closer" with the 25th being
6" and the 75th being 10".

Diving into the individual models/ensembles, the ECMWF/EPS has
actually expanded the higher snow amounts across the south and
southeast compared to some of the previous runs, with a very sharp
cutoff north (unfortunately right near the Richmond metro). The
Canadian has also moved a touch north with the ~3-6" amounts, but
keeps the 6"+ amounts mainly confined to the southeast. Finally, the
GFS/GEFS has trended south with the highest amounts (especially
compared to the 00z/29 run), keeping a majority of the 6"+ amounts
across the far south/southeast and the overall highest amounts just
south of the CWA across NC. Finally, we are just starting to come
into range of the CAMs which may provide a bit more clarity this
evening and tonight. For now, the forecast resembles a blend between
the previous forecast and the latest model guidance. Overall, snow
amounts were lowered ~1-2" across the forecast area this afternoon,
with amounts ranging from 0.5-2" across northwestern portions of the
forecast area, to ~2-5" through the Richmond metro to the Tri-
Cities, to 4-7" across south central Virginia over to Eastern Shore,
to 7-12+" across southeast Virginia (Hampton Roads) into northeast
North Carolina.

One trend that continues in most of the models is a "piece" of the
surface high over the Plains ridging SE into the local area Friday
into early Saturday, with low pressure across the eastern Gulf coast
showing an inverted trough extending north into the southern
Appalachians. This has trended to an initial overrunning precip
event (all snow). For the Piedmont, this portion of the storm may
account for a majority of the snowfall. SLR values will be very
high, 15:1 to 18:1 so even a relatively low amount of QPF could lead
to a significant accumulation (which will be efficient on area roads
given temperatures well below freezing).

Part 2 of the storm gets amped up later Saturday, and is expected to
peak Saturday night into early Sunday. The models (even the GFS) are
all in pretty good agreement that the digging upper trough becomes
cutoff as it drops SE from the TN Valley (at 12Z/Sat), to the GA-SC
coastal plain by Saturday evening (00Z/Sun). The resulting low is
forecast to deepen by as much as 15 mb/6 hr Sat evening as it drifts
NE off the coast. Therefore, in addition to heavy snowfall, which is
of highest confidence across SE VA and NE NC, very strong winds are
likely to develop for coastal areas, with winds rather strong even
for inland zones. Strong winds and a significant snowfall are
expected within the Watch, with highest confidence across
southern/SE VA and NE NC. Added blizzard wording to the Winter Storm
Watch for portions of Hampton Roads and coastal northeast North
Carolina and Blizzard Warning may likely be needed for these
locations. Winds may gust to 50-60 mph along the coast Saturday
night into Sunday.

Please keep a close eye on the forecast over the next 24 hours, with
forecast confidence remaining below average for this timeframe. A
~50 mile shift in the coastal low will have drastic impacts to the
final snowfall amounts. Additional messaging and headlines will need
adjustments over the next few forecast cycles.


KEY MESSAGE 2...A quick burst of light to moderate snow is possible
Friday afternoon and evening ahead of the main winter storm,
especially across portions of central and south central Virginia.
Due to the very cold temperatures, any snow could quickly accumulate
on surfaces, including roadways. This is a low confidence, but
potentially high impact event.

Latest CAMs, including the 18z HRRR and NAM 3km show the potential
for light snow developing across areas south of I-64 Friday
afternoon/evening. If snow does fall, there is a possibility (~20 to
40% probability) of accumulations up to 0.5". Air temperatures will
be well below freezing during this timeframe, allowing for efficient
accumulation on all surfaces. While this scenario is fairly low
confidence, there could be significant travel impacts if it does
happen.


KEY MESSAGE 3...Well below normal temperatures remain through early
next week, keeping localized impacts (i.e icy roads) in place
through the weekend. The coldest air wind chills are expected
Saturday night into Sunday morning and an Extreme Cold Watch has
been issued for the entire forecast area. A Cold Weather Advisory is
in effect tonight for portions of the Maryland and Virginia Eastern
Shore.

Tonight will again be very cold, though winds are expected to be
light as high pressure extends into the area, keeping wind chills
near ambient temps that will mostly be in the teens or mid to upper
single digits NW. However, there will be enough of a light breeze
tonight across portions of the Eastern Shore to allow for wind
chills to drop into Cold Weather Advisory territory. As a result,
another Cold Weather Advisory has been issued tonight into Friday AM
for the Maryland Eastern Shore and Accomack County, VA where wind
chills as low as 0 are expected. Friday will see highs struggle to
get out of the mid 20s for much of the northern half of the area.
Saturday will be even colder with highs in the low to mid 20s for
most. An Extreme Cold Watch has been issued for Saturday night into
Sunday morning where the combination of a strong N to NW wind and
air temperatures in the low to mid teens will result in wind chills
as low as 0 to 10 below.

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
As of 642 PM EST Thursday...

VFR conditions will prevail through tomorrow evening at all
terminals. Upper level cloud cover will continue to stream across
the terminals, with some lower level clouds starting thicken up
tomorrow morning. A few light snow showers are possible tomorrow
afternoon at RIC, ORF, and PHF, but confidence is very low in this
so have not included in the TAFs at this time. Winds will generally
remain light from the northwest before becoming northeasterly
tomorrow morning.

Outlook: A winter storm will impact the area later Friday
through Sunday. Snow is expected to spread eastward to include
most terminals overnight into Saturday. May become +SN with low
VIS Sat night into Sun morning. Winds will also become strong
later Sat, with the highest gusts closer to the coast.
Widespread flight restrictions are possible with this storm.

.MARINE...
As of 320 PM EST Thursday...

Key Messages:

- Small Craft Advisories remain in effect across the coastal
  waters north of Parramore Island into this evening.

- Confidence remains high in high-end Gale to Storm conditions
  this weekend as a strong coastal low develops off the
  Carolinas. Freezing spray and high seas are expected this
  weekend.

- Coastal flooding is increasingly likely across the Lower
  Chesapeake Bay, Lower James River, and Virginia Beach and
  eastern Currituck Counties Sunday morning.

NW winds 10-15 kt with gusts up to 20 kt across most of the local
waters and 15-20 kt with gusts up to 25 kt across the northern
coastal waters north of Parramore Island were noted this afternoon.
As such, have ended all SCAs except for the coastal waters north of
Parramore Island where they remain in effect until 7 PM.
Additionally, while some light freezing spray remains possible
through tonight, it appears marginal enough to refrain from issuing
additional Freezing Spray Advisories at this time.

Strong high pressure builds south from the northern Plains into the
Gulf Fri into Sat. Meanwhile, a coastal low is expected to develop
off the Southeast coast Fri night into Sat before tracking ENE off
the coast through Sun. Most model guidance shows the potential for
quite impressive pressure falls with WPC depicting a 980mb low off
of the Outer Banks by 12z Sun. Recent model trends have favored a
farther south track of the low which has resulted in slightly lower
winds forecast for the local waters. However, there remains a
moderate-high potential for widespread Storm conditions this weekend
across the Ches Bay, coastal waters, Lower James River, and
Currituck Sound with Gale conditions likely across the upper rivers.
The probability for 48 kt gusts was 30-60% across the Ches Bay
(highest across the Lower Bay), 40-65% across the northern Coastal
Waters north of Cape Charles Light, and 70-80% across the southern
coastal waters south of Cape Charles Light. Therefore, have
maintained all Storm Watches and Gale Watches. Seas of 8-12 ft
across the northern coastal waters and 10-15+ feet across the
southern coastal waters (highest across the NC coastal waters) are
expected given the strong winds. Additionally, given the high
probability for snow (potentially heavy), periods of zero visibility
are increasingly likely across the coastal waters Sat into Sun.
Winds become NW behind the low and gradually diminish Mon.

Tides/Coastal Flooding...

Given the strength of the low coinciding with higher
astronomical tides, widespread coastal flooding is increasingly
likely with the Sun morning high tide. Moderate coastal flooding
remains possible across the Lower James River and lower Ches
Bay Sun with moderate to locally major coastal flooding possible
across the Mouth of the Bay and the Virginia Beach and
Currituck Outer Banks coastline. Minor coastal flooding remains
possible across the Atlantic coastline of the Eastern Shore.
Will hold off on Coastal Flood Watches at this time, however,
will likely need them in future updates as confidence increases.
Additionally, given the strong N/NNW winds, low water levels
are likely across portions of the middle Ches Bay and Currituck
Sound. Low Water Advisories may be needed in future updates.
