Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
845 PM EDT Sun Aug 10 2025

.SYNOPSIS...
Warm temperatures, mostly dry conditions, and low humidity look to
continue through Tuesday as broad high pressure remains nearby.  A
frontal system may gradually approach from the west Wednesday into
Thursday as the high moves out to sea. This will result in increasing
heat and humidity as well as thunderstorm chances across the region
later in the workweek and into the upcoming weekend ahead.

&&

.NEAR TERM /THROUGH MONDAY/...
Satellite imagery shows mostly clear skies across the forecast
area this evening. Skies will remain clear through the first
half of the night, but low clouds may develop during the second
half of the night, especially to the east of the Blue Ridge, as
deeper moisture starts to advect in from the south. Patchy fog
will also be possible, especially to the west of the Blue Ridge,
where skies will remain clearer. Winds will be either light out
of the south to southeast or calm. Temperatures will be warmer
than preceding nights, with lows in the 60s for most (upper 50s
in the mountains).

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
High pressure will drift offshore Monday into Tuesday. A couple
of showers could develop Monday afternoon near the central
Shenandoah Valley vicinity. Coverage should be low given a ridge
of high pressure aloft. High temps likely approach 90 Monday
afternoon.

A slightly higher potential for showers and a couple thunderstorms
will exist mainly west of the Blue Ridge Tuesday afternoon as
the ridge continues to gradually break down and heat and
humidity increase further. High temps are expected to reach into
the 90s for much of the area Tuesday afternoon.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
A typical hot and humid (August) summertime pattern will return to
the area during the extended period. High temperatures each day
should be in the upper 80s and lower 90s (upper 70s/80s mountains),
with dewpoints generally in the lower 70s. Daily chances for
afternoon showers and thunderstorms will accompany the increased
heat and humidity.

The highest coverage of storms will likely be on Wednesday as an
upper trough passes to our north and west through the Great Lakes,
providing some glancing large scale ascent. This same upper trough
will drive a decaying cold front southeastward toward the area later
Wednesday night into Thursday morning. The front should wash out
overhead Friday into the weekend, so little in the way of relief
from the heat and humidity is expected. With ample amounts of low-
level moisture remaining in place, showers and thunderstorms may be
possible each afternoon Thursday through Saturday, albeit with lower
areal coverage than Wednesday.

&&

.AVIATION /01Z MONDAY THROUGH FRIDAY/...
Conditions are VFR at all terminals this evening, but low clouds
will move in later tonight, with either IFR or low-end MVFR
ceilings expected at most of the terminals late tonight through
about mid-morning. Improvement back to VFR conditions is
expected by tomorrow afternoon.

A shower or thunderstorm cannot be ruled out at KCHO, KSHD, and
KMRB on both Monday and Tuesday afternoon as low level moisture
increases. Any coverage will be fairly isolated and confined to
the diurnal peak heating period. Winds will remain out of the
south and southeast at less than 10kts through Tuesday.

Prevailing VFR conditions are expected Wednesday through Friday
across the terminals. Some temporary reductions may be possible due
to diurnally driven showers and thunderstorms each afternoon.
Greatest coverage looks to be Thursday as the front drifts into the
area and eventually dissipates. Additional thunderstorm chances are
expected during the afternoon and early evening hours heading into
the upcoming weekend ahead. Winds will remain light out of the west
and southwest Wednesday before turning to the northwest Thursday and
northeast Friday.

&&

.MARINE...
Sub-SCA level southeasterly winds are expected to continue through
Tuesday as broad high pressure remains nearby. Some marginal
southerly channeling is possible during the late afternoon and
evening hours Monday and Tuesday as high pressure pushes further
offshore. Shower and thunderstorm chances do not return to the
waters until Wednesday although an isolated shower or t-storm is
possible along the bay/river breeze Tuesday. Confidence in this is
low given residual upper level ridge suppression over the region.

Sub-SCA level winds are expected Wednesday through Friday, with
prevailing winds out of the southwest on Wednesday, and northwest on
Thursday. Special Marine Warnings may be possible either afternoon
or evening in association with thunderstorms.

&&

.TIDES/COASTAL FLOODING...
Elevated tidal anomalies look to continue through Monday given the
recent full moon and light onshore flow. Minor coastal flooding is
possible with high astronomical tides (especially at Annapolis and
perhaps Dahlgren/Alexandria).

&&
