AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
130 PM EDT Fri Apr 4 2025

.SYNOPSIS...
A backdoor cold front drops into the Mid-Atlantic today, before
retreating back to the north Saturday morning. A higher chance
for showers and thunderstorms arrives late Sunday into Monday as
a cold front slowly crosses the area. Much cooler temperatures
are expected early next week with the potential for below
freezing temperatures Tuesday night.

.NEAR TERM /THROUGH TONIGHT/...
As of 1110 AM EDT Friday...

Key Messages:

- Well above average temperatures today for most of the area, with
  highs rising into the 80s.

- Scattered showers and thunderstorms are possible from late
  afternoon through tonight. The storms will very likely be
  sub-severe, though highly localized gusts to 40-50 mph can`t
  completely be ruled out between 5-9 PM.

Late morning wx analysis shows developing low pressure in the lower
Mississippi River Valley, with high pressure offshore of the SE
CONUS coast. A backdoor cold front remains just to our north, with
the wind direction still WSW at SBY/OXB. Expect temps to rise into
the 80s across the vast majority of the area today as the front
fails to make it past the Northern Neck/Eastern Shore by mid/late
aftn before picking up speed and crossing most of the FA this
evening-tonight. The front is progged to stall INVOF the VA-NC
border by early Sat AM. There will be a rather quick temperature
drop w/ the FROPA, especially near the coast with the cooler water.
As the front advances toward the area, scattered showers/tstms will
likely develop by 5-6 PM, with the highest coverage expected to be
along the I-64 Corridor from the central VA Piedmont to RIC Metro
area. The convection might make it into Hampton Roads this evening
before gradually becoming elevated and weakening overnight. In
addition, the highest coverage of showers/storms will move back to
the north and east overnight. Not everyone will see rain and NE NC
very likely remains dry, as PoPs are no higher than 30-50%. The
storms are expected to be sub-severe but localized 40-50 mph gusts
can`t completely be ruled out between 5-9 PM given fairly strong sfc
heating and moderate instability (1000-1500 J/kg MLCAPE) present.
Lows fall into the mid 50s-lower 60s in most areas.

.SHORT TERM /SATURDAY THROUGH MONDAY NIGHT/...
As of 400 AM EDT Friday...

Key Messages:

- Well above normal temperatures expected this weekend.

- - Scattered to numerous showers and thunderstorms are possible
  Sunday afternoon through Monday along a cold front.

The backdoor cold front will continue to lift northwards during the
day Saturday, inviting well above normal temperatures back across
the area. Have nudged temperatures up a few degrees for Saturday
since the front will be lifting through a majority of the forecast
area Friday night, giving the warmer airmass time to filter in.
Temperatures will be in the lower to mid 70s on the Eastern Shore,
and range between the lower 80s in the NE to the mid to upper 80s in
the southern portion of the area. A strong ridge centered off the SE
coast in the western North Atlantic will remain in place through
Saturday, which will also aid in temperatures rebounding quickly.

By Saturday night, the stalled front that has been reeking havoc
on the Mid-South and Red River Valley area will finally start
to move towards the East Coast as the aforementioned ridge
starts to break down. The front is progged to move through the
area Sunday night through Monday morning. Abundant atmospheric
moisture, along with some instability and good forcing will be
present as the front moves through, which could lead to higher
rainfall rates. Statistical guidance is suggesting a good slug
of rainfall will accompany this front and that all of our
forecast area could likely see 0.5" or greater during this
event.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
As of 400 AM EDT Friday...

Key Messages:

- Cooler, seasonable temperatures return next week with possible
freezing low temperatures Tuesday night.

By Monday night, mostly of the rain will have moved offshore with
some trailing rainfall still possible in SE VA and NE NC. High
pressure will start to build in behind the front, and a drier, much
cooler airmass will begin to filter in. Temperatures will only reach
the 50s across the forecast area Tuesday, which is a few degrees
below normal for this time of year. Mostly clear skies and dry
conditions will prevail Tuesday through the first part of Wednesday
night. With lighter winds and clear skies on Tuesday night,
radiational cooling is likely. Have dropped temperatures a degree or
two below guidance to account for this. A decent chunk of the
forecast area may see temperatures drop into the upper 20s to lower
30s, so Frost/Freeze products may need to be issued Tuesday night.
Temperatures will remain a few degrees below normal again on
Wednesday, with highs still generally in the 50s. Flow will become
onshore, so high temperatures immediately along the coast may be a
few degrees cooler than inland.

Wednesday night there is good agreement that a shortwave will
start to approach the forecast area, so we will see increasing
cloudiness overnight. There is a chance for radiational cooling
again Wednesday night, but the window will be confined to the
first few hours of the night ahead of these clouds. Temperatures
will drop into the mid 30s to lower 40s. Heading into the
latter part of next week is where global models start to diverge
on what becomes of the aforementioned shortwave, with widely
varying solutions. The details of the forecast will be ironed
out over the next few days as the details become more clear.

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
As of 130 PM EDT Friday...

CIGs are VFR to MVFR (but above 2000 ft) early this afternoon as
a backdoor cold front slowly approaches from the NNE. The front
will cross SBY by 21z before crossing the VA terminals between
23-02z...but will likely stall before reaching ECG. Scattered
tstms are possible along the front later this aftn and
especially this evening at RIC/PHF/ORF. PoPs are below 50% but
have included a PROB30 group at each of these three sites for
TSRA and VRB gusts to 30 kt. The most likely timing for TSRA is
from 22-04z. In addition, a round of MVFR to IFR CIGs is likely
later tonight through Saturday AM at RIC/ORF/SBY/PHF before
CIGs improve during the day as the front moves back north as a
warm front. WSW winds at ~10 kt become NE-E behind the front
before shifting back to the SSE then S on Saturday.

Outlook: Dry/VFR Saturday afternoon and Sunday as the front
moves back north of the area. A cold front approaches from the
west Sunday and moves across the area Sunday night into Monday
bringing widespread showers and a few tstms. At least periodic flight
restrictions are likely during this time period.

.MARINE...
As of 255 AM EDT Friday...

Key Messages:

- SCA conditions continue over the coastal waters N of Parramore
  Island this morning with persistent SE swell.

- Another period of SCA conditions is likely later this weekend and
  early next week ahead of, and behind a strong cold front.

Compressed pressure gradient between 1032+mb sfc high pressure
over Bermuda and low pressure over Quebec and Ontario is
maintaining SSW winds 15-20 kt over the local waters, highest
over the nearshore coastal zones and with a bit of enhancement
from channeling over the lower James and Ches Bay. Small Craft
will be allowed to drop on time later this morning at 4am, as
winds slowly diminish with winds turning to the W-SW. SCAs will
be extended for the coastal waters north of Parramore Island
with SSE Swell 3-4ft/6 seconds holding seas up in the 4-5 ft
range through mid-morning before seas subside a bit with winds
turning offshore. A cold front drops across the region from the
north-northeast from midday far northern waters and through this
afternoon farther south. Winds veer around to the NNE 10-15 kt
post-frontal, with the front likely to stall Friday evening
along or just south of the NE NC waters. A few gusts to ~20 kt
are possible coincident with the frontal passage, but expect
predominate conditions remain sub-SCA, and therefore no
additional headlines are planned at this time.

The front will lift back to the north as a warm front Saturday
midday into Saturday afternoon, with winds to veer back around
to the SSE then S, increasing to ~15 kt. Winds will increase
further Saturday night to ~20 kt with frequent 25 kt gusts as
the gradient tightens behind the previously referenced Bermuda
high and an approaching (stronger) cold front. SCA conditions
will likely begin later Saturday night and continue through
Monday, with a brief reprieve likely by Monday afternoon. Winds
peak during the day on Sunday, with speeds of 20-25 kt likely
with gusts as high as 30 kt (highest on the rivers/nearshore due
to better mixing over land). The front will move through the
area on Monday, with a secondary front moving through Monday
night into Tuesday. Good CAA is expected behind the secondary
front and another round of solid/high-end SCA conditions looking
increasingly likely Tuesday afternoon and evening through
Wednesday morning. Thereafter, high pressure briefly builds back
across the region, resulting in a decrease in wind speed by
Wednesday afternoon. Seas build back to 4-6 ft (with waves of
3-4 ft likely) by Sunday...and both seas and waves remain
elevated through early next week.
