AREA FORECAST DISCUSSION

815 PM EDT Sat Sep 20 2025
.SYNOPSIS...
A backdoor front drops southward through the area today,
bringing a return to seasonably cool and cloudy conditions this
weekend. A warm up in temperatures from high pressure returns
early next week.
&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
As of 815 PM EDT Saturday...
Key Messages:
- A weak cold front has pushed into northern NC this evening,
  and will drop south of the area overnight.
- An overcast sky is expected overnight, with lows in the low
  to mid 60s.
Latest analysis shows 1028+mb sfc high pressure centered over
QC and northern New England. Weak cold front is now along/just
south of the VA/NC border as of this writing, with temperatures
in the mid 60s to low 70s north of the front, with mid 70s south
of the front. Showers and storms which developed earlier this
afternoon have weakened with post- frontal stabilization. Will
likely see a few more isolated showers across northeast NC as
the front settles south, but otherwise remaining mainly dry for
the rest of the night.
Becoming overcast tonight, expect low stratus to build into the
area overnight as that front moves into the Carolinas. Visibility
guidance suggests there could also be some patchy fog again
late tonight into early tomorrow morning, primarily in piedmont.
However, given the cloud cover, have kept dense fog mention out
for now. Overnight lows will be in the low to mid 60s for most
of the area, under a mostly cloudy sky.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/...
As of 245 PM EDT Saturday...
Key Messages:
- Cooler temperatures in wake of backdoor cold front.
- High pressure returns to the region, keeping conditions dry.
Behind the cold front, a weak low pressure will form along the front
on Sunday, but model guidance continues to show the low
remaining further off coast in the Atlantic ocean. Therefore,
still expecting dry weather tomorrow. High pressure will return
to region but partly to mostly cloudy skies are expected Sunday
and Monday with around average high temperatures in the mid 70s
to around 80 and lows in the upper 50s to lower 60s.
&&
.LONG TERM /TUESDAY THROUGH SATURDAY/...
As of 245 PM EDT Saturday...
Key Messages:
- Mainly dry with near to slightly above average temperatures early
  next week.
- Rain chances and cooler temperatures potentially return by the
  middle and end of next week.
Ridging will build offshore of the SE CONUS coast next week, while a
strong upper low dives into the central Plains. Model guidance
continues to indicate that high pressure will return to south of the
area by early next week, favoring a warming trend due to developing
return of flow out of the south. Highs will rebound to the low-mid
80s forecast for Tuesday and Wednesday. Daily chances for
showers/thunderstorms return by the middle of the week due to
the approaching upper low and trough, which is expected to
advance eastward through the MS Valley during the middle and end
of next week as high pressure returns to the Quebec region.
This will bring slightly below average temperatures to region by
the end of the week.
&&
.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
As of 815 PM EDT Saturday...
A backdoor cold front has pushed south through the terminals to
begin the 00z TAF period, with MVFR to low-end VFR CIGs across
the region. Thicker cloud cover will spread south through this
evening and overnight as the front continues to drop south.
Confidence has increased that IFR CIGs develop late this evening
into the overnight. There is a chance for some patchy fog at
RIC around sunrise, but guidance keeps fog primarily to the
west, so have held out for now. VFR returns to the terminals by
late Sunday morning into early afternoon (15-17z, 11a-1p), as
the clouds scatter out. NE winds will be 5-10kt through the
period.
Outlook: A better chance for more widespread sub-VFR CIGs and
patchy fog are expected Sunday night into Monday morning. High
pressure returns Monday and Tuesday with likely VFR conditions.

.MARINE...
As of 300 PM EDT Saturday...
Key Messages:
- Small Craft Advisories are in effect for the Atlantic coastal
waters, mouth of the Chesapeake Bay, and Currituck Sound from late
tonight into Sunday night. SCAs linger into Monday for the Atlantic
coastal waters due to elevated seas.
- There is a high rip current risk for both tomorrow and Monday.
This afternoon, a backdoor cold front has crossed the marine area
and is now located just south of the local waters. Meanwhile, high
pressure is building to our north over Canada is SE into New
England. Winds have become NE in the wake of the front, generally
ranging from 5 to 10 knots across the southern waters and 10 to 15
knots further north. Seas are generally around 2 feet, but have
increased to 2 to 3 feet across the far northern waters. Waves in
the Bay are around 1 foot (2 feet at the mouth).
High pressure slides SE across New England and into Atlantic Canada
into tonight and builds to ~1030mb. High pressure remains over the
Canadian Maritimes Sunday as an inverted trough sharpens off the NC
coast. Winds become NE and increase to 10 to 15 knots over all the
waters later this evening into tonight. Winds increase further later
tonight into Sunday, becoming 15 to 20 knots with gusts approaching
25 knots for the ocean, mouth of the Chesapeake Bay, and Currituck
Sound (remaining 10 to 15 knots with gusts ~20 knots elsewhere).
Meanwhile, seas to 3 to 4 feet later this evening into tonight (from
N to S), and then 4 to 5 feet N to 5 to 6 feet S Sunday into Sunday
night. SCAs remain in effect for the coastal waters, mouth of the
Bay, and Currituck Sound beginning late tonight and continuing into
Monday (longest for the coastal waters due to linger 5+ feet seas).
Local wind probs for sustained 18 knots and gusts to 25 knots
continue to drop off quickly W of Little Creek, thus the SCA doesn`t
extend past the mouth of the Bay.
The pressure gradient relaxes early next week as high pressure
builds S into the region and then nudges offshore by midweek. Seas
will be slow to subside Monday, but sub-SCA conditions should
gradually return and then prevail for the entire marine area by the
middle of next week.
Rip Currents: A high risk is forecast for Sunday due to an
increasing NE wind and nearshore waves of 4-6ft. A high risk is
expected to continue into Monday due to elevated seas in combination
with some long period swell from distant TS Gabrielle (forecast to
be Hurricane Gabrielle by that point).
