AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
911 PM EDT Thu Oct 9 2025

.SYNOPSIS...
High pressure builds north of the area tonight into Friday with
much cooler and drier air filtering into the area. A coastal
low develops off the Southeast coast this weekend into early
next week, resulting in the potential for heavy rain and breezy
conditions for the eastern half of the area.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
As of 900 PM EDT Thursday...

Key Message:

- Chilly and dry weather expected tonight.

An expansive high across the Northeast extends down across the area,
with a frontal draped across the northern FL panhandle this evening.
The gradient across the local area remains tightened, which has
resulted in the continuation of gusty winds, especially along the
coast. Temperatures are in the 50s to lower 60s, with a few isolated
areas in the piedmont already in the upper 40s. GOES Nighttime
Microphysics is highlighting a swath of cloud cover across south-
central and eastern VA and NE NC spreading westward. The combination
of this increasing cloud cover and light (not calm) winds will keep
areas from radiating as much as initially thought a few days ago and
keep the threat of frost/freeze out of the piedmont area tonight.
Lows tonight will be in the low 40s for northwestern counties, mid
to upper 40s in other inland locations, and low to mid 50s closer to
the coast.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY/...
As of 345 PM EDT Thursday...

Key Messages:

- Dry/cool weather continues into Friday.

- Rain chances increase throughout the day Saturday as a
  potentially significant coastal system begins to impact the
  region.

Another nice, autumnal day is in store for Friday. Sfc high pressure
to the N slides offshore and low pressure starts trying to spin up
somewhere near the coast of the SE CONUS. It will be another day of
highs in the mid to upper 60s with maybe some low 70s closer to the
Albemarle Sound. Skies start out mostly sunny, then cloud cover
increases in the afternoon. Breezy again in the afternoon with gusts
between 15-25mph (highest at the coast). Lows Fri night will
generally be in the mid 50s to low 60s, but NW counties will be
chillier in the upper 40s to low 50s.

Will see degrading conditions Saturday as low pressure to the S
develops into a coastal storm. Global models are not terribly
different through Saturday afternoon, though the ECMWF shows a
broader low that is just a tad farther south than the GFS.
Regardless, rain chances steadily increase through the day,
especially E of I-95. Starting the morning off with Chnc PoPs
across the area (35-40%), then increasing up to 60% at the coast
in the afternoon. Less than an inch of QPF expected through Sat
evening with highest amounts closer to the Albemarle Sound.
Highs will be in the upper 60s inland and the low 70s in the
east. Unfortunately, the 12z suite of models start to diverge
heading into Sunday.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
As of 345 PM EDT Thursday...

Key Message:

- A strong coastal system continues Sunday into Monday, bringing
heavy rain and gusty winds to eastern portions of the area.

Sat night is unfortunately where confidence decreases, even compared
to last night`s forecast package. The 12z GFS diverged from the
other deterministic models, bringing the center of the low right up
the coast. Meanwhile, the ECMWF depicts a broader low further
offshore and the Canadian also keeping it offshore. The ensembles do
not have quite so much spread with the mean location of the low
offshore. These differences affect the timing of impacts,
location of heaviest rain, and strength of the winds. Not
comfortable straying far from the NBM given the uncertainty, and
do feel the trend in the NBM PoPs is going the right direction.
PoPs increase to 60-80% with highest values right along the
coast late Saturday night into Sunday morning. Highest PoPs then
shift to the NE Sun morning and gradually taper off SW to NE
going into Monday. Will say that the end time of rain is up in
the air at this point since there is even more spread in the
guidance on what happens to the low after Sunday. Some keep the
low close by through early next week while others lift it out by
Monday. QPF through 00z Mon is for 2-3" right along the coast,
tapering down to ~0.5" in the far west. Will note that there is
a low end prob of 4" of rain with both GEFS and Euro Ens showing
a 10-30% prob immediately near the coast. The WPC has
maintained the slight risk ERO for coastal areas for Sat and
Sun. The other concern for this period is the wind. Currently
forecasting wind gusts of 45 to 55+ mph possible along the
immediate coast (25 to 35 mph inland). Cannot rule out high wind
warnings or wind advisories at this point. Conditions should
gradually improve Tuesday and beyond as the low weakens/moves
offshore and high pressure begins to build back into the area.

&&

.AVIATION /01Z FRIDAY THROUGH TUESDAY/...
As of 740 PM EDT Thursday...

VFR conditions will prevail at all terminals through the TAF period.
Mostly dry conditions are expected through 00z/10, though a few
sprinkles at PHF and ORF are possible this evening. There will
likely be increasing cloud cover at all sites as a low starts to
develop off the SE coast. Gusts of 15-20 kts will continue at
the coastal sites, through tomorrow, with 5-10 kt sustained
winds expected at the inland terminals.

Outlook: Sub-VFR CIGs, elevated winds, and moderate to heavy
rain are likely as we head into Saturday as low pressure
develops offshore. Periods of sub-VFR conditions likely continue
through the weekend and into early next week.

&&

.MARINE...
As of 340 PM EDT Thursday..

Key Messages:

- Small Craft Advisory conditions persist across most of the local
  waters through Saturday.

- Low pressure develops south of the area this weekend. While uncertainty
  remains, dangerous marine conditions are forecast from
  Saturday evening into early next week. Storm and Gale Watches
  continue unchanged from the previous forecast.

1034mb high pressure has moved into the Great Lakes region while
yesterday`s front is now well south (northern FL) of the local area.
Waves in the bay are 2-3 ft with seas offshore 4-5 ft N and 5-7 ft
S. The pressure gradient remains steep across the region with NE
winds generally 15-20 kt with gusts to 25 kt. We are in a bit of a
lull in winds late this afternoon, but an additional surge of cooler
air should bring a modest increase in winds this evening into early
tonight. Winds again decrease Friday into the first part of
Saturday, but the forecast retains 15-20 kt winds in the southern
waters through Saturday.

The main focus continues to be the developing coastal low Saturday,
which will track northward over or close to our waters Sunday into
Monday. The exact evolution of the low remains of low confidence at
this point, in fact, uncertainty has actually increased with the 12z
guidance suite. The GFS now shows a slightly inland track across the
region while the remaining guidance keeps the circulation center
well offshore. This disconnect has rather significant differences in
wind speed and direction over the local waters. Therefore, did not
stray too far from the previous forecast pending (hopefully) more
clarity over the next 24 hours. Regardless of the track/intensity
details, there remains high confidence for significant marine
hazards, including high winds (potentially to Storm force) and
dangerous seas. NE winds increase considerably later Saturday into
Saturday night, with the peak in the winds Sunday into early Monday
as the low makes its closest approach to the area. Peak wind gusts
range from 45-50 kt on the coastal waters, 40-45 kt in the
Chesapeake Bay, and 35-40 kt in the upper tidal rivers. Left the
Gale and Storm Watch headlines unchanged with this forecast cycle.
There is the potential for expansion of the Storm Watch into the
Mouth of the Chesapeake Bay but was not comfortable making changes
with the very disjointed 12z guidance. Most guidance has backed off
on the potential for the low to stall offshore it occludes late
Monday into Tuesday and the models that still show this scenario
have a much weaker low pivoting around. Accordingly, have decreased
winds a bit from the previous forecast Tuesday and Wednesday. The
gradient finally starts to relax by mid week with improving marine
conditions. Seas are forecast to peak in the 13-17 ft range, with
higher values not out of the realm of possibility. Waves in the
Chesapeake Bay range between 5-8 ft, with 9-10 ft possible at the
mouth of the bay. As winds decrease next week, so will the seas, but
only gradually.

.TIDES/COASTAL FLOODING...
As of 910 PM EDT Thursday..

The next high tide cycle is the lower astronomical tide compared
to this morning and the subsequent cycle on Friday morning, so
only nuisance tidal flooding is expected tonight. That being said,
this morning`s high tide over performed in a few spots and
guidance shows the potential for another round of minor
flooding across the lower Ches Bay, lower James River, and
Currituck Outer Banks for Friday morning`s high tide. As such,
have issued a Coastal Flood Advisory for these areas.

Tidal anomalies remain level through early Saturday, with
another round of minor flooding possible during the Saturday
morning high tide across a similar region as the current Coastal
Flood Advisory. Tidal anomalies rise quickly late Saturday
through Sunday with widespread moderate to locally major coastal
flooding possible by Sunday. The highest confidence is across
the Ches Bay (especially the lower bay) and across locations
adjacent to the ocean. Water levels will be highly dependent on
the track of the low and the associated wind direction. The 18z
guidance suite has not aided in clarifying these details and was
notably lower with the highest predicted high tides compared to
earlier model guidance. Given how much lower the new model
guidance (ETSS and PETSS) was and the low confidence on the
exact track, have trended the forecast lower for many sites and
now have predominantly moderate coastal flooding on Sunday with
locally major across the lower bay. Will note that this is
dependent upon the exact track of the low and once models come
to a better consensus, confidence in the exact water levels
(and flood stages) will increase. The high tide cycle in the
late morning- early afternoon of Sunday continues to look the
most problematic, though additional flooding is possible into
early next week. Given the uncertainty and how far out the event
is, will hold off on any Coastal Flood Watches for now, but
they will likely be needed in subsequent forecasts.
