AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
216 AM EDT Tue Jun 17 2025

.SYNOPSIS...
A frontal boundary will remain nearly stationary along the
Virginia North Carolina border tonight, before washing out
across the area on Tuesday. An upper level ridge expands
northward Wednesday, leading to hot weather with lower rain
chances Wednesday, followed by hot conditions Thursday, with
scattered showers and storms as the next cold front approaches.
Mainly dry for the upcoming weekend.

&&

.NEAR TERM /THROUGH TODAY/...
As of 1000 PM EDT Monday...

Key Messages:

- The Flood Watch has been cancelled.

- Warmer Tuesday with highs into the mid to upper 80s for most
  of the area. A few strong storms possible across the NW late.

This evening, the frontal boundary has settled just south of
the forecast area (near the Albemarle Sound) and extends back
into western portions of the state. Low clouds and areas of
light rain/drizzle continues north of the boundary, with
temperatures ranging from the 60s across northern portions of
the area and the Eastern Shore, with 70s for the rest of the
area. With the front now south of the area, the heavy rain
threat has largely come to an end, thus the Flood Watch has been
cancelled across northeast NC. Significant rainfall fell
earlier today across portions of the northeast NC, with pockets
of 2-3+".

Otherwise, a few showers will be possible overnight, even to
the north, but rainfall amounts will generally be light. Some
patchy fog/low stratus is likely early Tuesday morning, but do
not expect widespread dense fog. Lows will range from the mid
60s N to the lower 70s S.

Tuesday will tend to begin with low clouds, and possibly patchy
drizzle, but upper level heights are forecast to rise, as the
next trough approaches from the OH/TN Valley, and the upper ridge
across Florida expands N. This should lead to increasing
amounts of sunshine by late morning/early aftn, allowing highs
to rise into the mid to upper 80s by later aftn (upper 70s to
lower 80s eastern shore). By late aftn, another shortwave, this
one a bit stronger, is expected to approach from the west, and
with decent instability parameters developing (at least well
inland), some showers/storms will be possible, mainly after 3
PM. Shear values are not impressive (20-30 kt at best), but
mid level lapse rates are a bit better than the past several
days and may compensate for the lack of shear. The primary
threat from any severe storm is damaging winds, with the threat
mostly limited to the nrn piedmont. SPC maintains a Marginal
Risk for severe weather in this area.

.SHORT TERM /TONIGHT THROUGH THURSDAY/...
As of 355 PM EDT Monday...

Key Messages:

- Hot and humid Wed and Thursday, with heat headlines possible
  in the SE.

- Severe Tstms possible late Thursday.

Aside from a few showers/storms late in the day Wed, conditions
should be mainly dry. With upper level ridging expands north towards
the region, summerlike heat is expected with highs rising into
the low-mid 90s for most of the area.Given the pattern, and
with the recent wet spell, have kept high temperatures both Wed
and Thursday on the cooler edge of guidance, but with dew pts at
or slightly higher than MOS numbers. Expect heat indices to
peak around 105F in the SE (where Heat headlines may be needed),
to the upper 90s to ~103F elsewhere. Given the high heat and
humidity, ample instability is expected along and ahead of a
cold front. In addition, model mid level lapse rates are
currently showing values >6C/Km, along with bulk shear values of
30-40kt. SPC has most of the region in a Day 4 15% Risk
(slight), and this would be mainly for wind, though large hail
will be possible as well.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
As of 400 PM EDT Monday...

Key Message:

Scattered showers/strong storms possible Thu evening, followed
by dry weather for Fri, probably lasting through the weekend.
While the NBM does not have any rain chances, there could be a
few storms Sat night/early Sunday across mainly NE sections of
the FA as both the GFS/ECMWF and ensembles are showing a
shortwave diving SSE from the Great Lakes (will continue to
monitor this over the next few days). Beyond that, there is
good model consensus that an upper level trough locks in place
over the NW CONUS, with a strong upper ridge across the central
and eastern CONUS. Some of the models depict 500 mb heights
rising to nearly 600 dm. The period next week looks quite hot
for a prolonged period given this setup. Humidity level might be
slightly lower given this ridge being more of continental
origin, though with the recent wet spell, this is uncertain.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
As of 215 AM EDT Tuesday...

CIGs have fallen back into IFR/LIFR range over area terminals,
with widespread IFR/LIFR CIGs at all sites persisting into mid-
morning (12-14z) Tuesday morning. In addition to the low CIGs,
patchy fog/drizzle will also be possible, reducing VSBYs to MVFR
or IFR at times. Conditions begin to improve later Tuesday
morning, with CIGs becoming MVFR ~13-15z. CIGs do look to
improve to high-end MVFR to VFR by late in the period (after
18z). However, some widely scattered afternoon/evening showers
and thunderstorms are possible this afternoon, initially with
afternoon seabreeze along the coast, and then with convection
arriving from the west late Tuesday afternoon/early Tue evening
that may lead to localized restrictions. Chances of showers/storms
at terminals remain low enough to hold out mention for now, but
will re-evaluate later this morning.

Outlook: Primarily VFR conditions are expected (outside of
patchy AM fog in the typical spots) again tonight into early
Wednesday. Additional late day and evening convection is
possible on Wednesday afternoon, with more widespread coverage
expected Thursday afternoon/evening, as a cold front crosses the
region. Very warm, dry, with VFR conditions for Friday into
the weekend.

&&

.MARINE...
As of 330 PM EDT Monday...

Key Message:

- Relatively benign across the marine area through midweek
  outside of convection.

A quasi-stationary front was located along the southern border
of the forecast area as of afternoon analysis. It will remain
near southern reaches of the area through tomorrow before
lifting N as a warm front once again. Latest obs indicate E/NE
flow at 5-10kt. Buoy obs show seas of 2-4ft with highest seas
off the Eastern Shore. Waves in the bay and river are 1-2ft.
Onshore flow at 5-10kt continues tonight and through tomorrow,
becoming SE tomorrow afternoon. Scattered convection tomorrow
afternoon/evening may lead to isolated instances of elevated
winds/waves. Winds become S, then SW Tues night into Wednesday.
Seas will be 2-3ft and waves generally 1ft or less (higher in
mouth of bay). Expecting breezier conditions Wed into Thurs
ahead of a cold front. SW winds of ~15kt expected Wed, then
increasing slightly heading into Thurs as the front gets closer.
SCAs may be needed late Wed night through Thurs evening- best
chance is for the lower bay and James River.

&&

.TIDES/COASTAL FLOODING...
Onshore flow over the last couple of days has led to slightly
elevated tidal anomalies, particularly in the upper bay and tidal
portions of the Rappahannock/Potomac. While the upcoming high tide
should be lower than the this morning`s tide, there could still be
some lingering nuisance flooding. A Coastal Flood Statement was
issued for the upper Rappahannock River (Tappahannock gage) where
level may near the minor flood threshold this evening.
