AREA FORECAST DISCUSSION
National Weather Service Wakefield VA
725 AM EDT Thu Jul 3 2025

.SYNOPSIS...
Isolated afternoon showers are possible over southern portions of
the area today, but otherwise, mainly dry conditions are expected
through Saturday as high pressure builds in from the north, with
lower humidity expected. Low pressure along the southeast coast
drifts north Sunday, potentially bringing showers and a few storms
to the southern half of the area. Typical summertime conditions
are expected next week, with mainly afternoon and evening showers
and storms and seasonable heat and humidity.

.NEAR TERM /THROUGH TONIGHT/...
As of 700 AM EDT Thursday...

- Areas of fog early this morning persist across southern
  VA/interior NE NC. SPS remains in effect through 830 AM.

The latest WX analysis indicates a strong upper low (~550 dm),
centered across NW Quebec, with the axis of the upper trough
extending SW into the Great Lakes/OH Valley (with yesterday`s
portion offshore of the mid-Atlantic coast). At the sfc, a weak
sfc trough/stalled remnant frontal boundary is in place from the
southern New England coast SSW into the VA/NC piedmont. An area
of mid level clouds has spread into central VA, improving VSBYs
somewhat, though areas of fog (covered w/ an SPS) remain through
8-9 AM over south central VA and interior SE VA/NE NC. Otherwise,
temperatures early this morning are primarily in the lower 70s,
with a few upper 60s W of I-95, and mid 70s near the coast in
SE VA.

For today, the upper low drops SE across Quebec, and moves into
northern New England tonight. The weak boundary in place over
the local area is expected to drift east and weaken offshore of
the local area later this morning. Meanwhile, a stronger cold
front out ahead of the upper trough drops SE through the
eastern Great Lakes and pushes into the northern mid-Atlantic
region late this aftn and evening. Will note that PWAT values
have dropped considerably compared to the past several days,
currently being analyzed at ~1.20" over NW sections of the FA,
and ~1.80" in the far SE (compared to >2.00"). Therefore, expect
mainly dry conditions later today despite the approach of
another cold front from the NNW, and the southern flank of a
shortwave passing by this aftn. The NBM keeps the entire area
rain-free today, but most of the CAMs show spotty aftn shower
activity along and S of I-64 this aftn. Have expanded the slight
chc PoPs up into south-central and interior SE VA (maintaining
it in NE NC) for this possibility (kept it S of RIC due to the
expectation of lowering dew pts but would not be surprised to
see a brief shower there as well). Highs today will mostly be
in the upper 80s to lower 90s, with dew pts dropping into the
mid- upper 60s N, while remaining in the lower 70s SE. Any
showers/tstms this aftn should rapidly dissipate towards sunset,
with a mostly clear sky tonight as sfc high pressure builds SSE
from the Great Lakes into the local area. Lows tonight avg in
the mid to upper 60s inland, with lower 70s along the SE coast.

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
As of 350 AM EDT Thursday...

Key Messages:

- Dry, warm, and noticeably less humid for the Fourth of July
  holiday into the first part of the weekend.

A pleasant and dry, but still warm, Fourth of July holiday looks to
be in store as an upper low moves off the northern New England
coast, allowing high pressure to settle in from the N. Highs
temperatures range from the mid/upper 80s to around 90 F, with
sunny to mostly sunny skies and light onshore flow. Dew points
range through the 60s (potentially down into the upper 50s at
peak heating across the northern 1/2 of the CWA), so it should
feel quite comfortable. Mainly clear and comfortable Friday
night with lows mostly ranging through the 60s (lower 70s SE
coast to lower 60s NW).

On Saturday, sfc high pressure will be centered across the NE
and mid-Atlantic region, with a broad upper low in place from
the eastern Gulf, across Florida and off the SE US coast. While
this system has a medium (50%) probability of taking on some
tropical/subtropical characteristics, it will be rather
difficult given weak flow aloft for this system to make its way
N into the local area. Remaining dry Saturday with with highs
again in the mid 80s coast to near 90F well inland with d

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 355 AM EDT Thursday...

Key Messages:

- A chance of showers across southeast VA and northeast NC
  Sunday. Otherwise, partly to mostly sunny and warm.

- Becoming increasingly hot and humid by next week with
  afternoon/evening storm chances.


The models do slowly lift the SE low pressure system north on
Sunday, the 03/00Z ECMWF lifting it farther north compared to
the GFS later Sunday, but all guidance keeps the system weak
(and the ECMWF brings it inland). The main effects will be for a
gradual increase in humidity on Sunday, with chc PoPs into the
southern portion of the FA. Higher humidity and seasonable WX is
expected Monday- Tuesday, along with chances of diurnal
showers/tstms well in advance of another cold front moving into
the Great Lakes. The aforementioned low or trough axis lingers
offshore into early next week before moving off to our NE
midweek. Daily high temperatures also warm back into the lower
90s with overnight lows in the upper 60s to lower-mid 70s.

&&

.AVIATION /11Z THURSDAY THROUGH MONDAY/...
As of 700 AM EDT Thursday...

Local IFR-LIFR in low stratus and fog, through ~13Z, then
mainly VFR today. Winds are generally light and variable, and
will become WNW at 5-10kt inland, while being light enough for
onshore flow near the coast this aftn. Slight chance of an
afternoon shower or storm across southern VA and NE NC, but
chances/areal coverage are much too low to account for in the
terminal forecasts at this time.

Outlook: VFR conditions tonight through Sunday AM as drier air
builds into the region behind the cold front. A few showers/tstms
possible by Sunday, mainly south, and all areas Monday.

&&

.MARINE...
As of 230 AM EDT Thursday...

Key Messages:

- Benign marine conditions today and through the weekend.

Benign conditions continue today as high pressure slides in behind a
cold front. Latest obs reflect westerly winds at 5-10kt. Seas are 2-
3ft and waves are around 1ft. Once high pressure slides overhead
later this morning, winds become lighter and variable. A sea breeze
looks to develop this afternoon. By the evening, light winds become
southwesterly. Another cold front crosses the waters early Friday
morning. Winds turn to the NNW behind it and increase to 10-15kt.
Cannot rule out a few gusts to 20kt Fri morning, especially in the
lower Ches Bay. Winds then turn onshore Fri evening and remain
onshore through the weekend. Wind speeds will typically be 5-10kt,
but will likely see slight increases in the evenings. Next chance
for SCAs would be Sunday evening with SE winds, but looks rather
marginal so far (~15kt with gusts ~20kt). Seas will remain at 2-3ft
today through the weekend. Waves will be 1-2ft.
