Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
832 PM EDT Sun Apr 14 2024

.SYNOPSIS...
Low pressure will track to our north tonight, and eventually
drag a cold front southward across the area Monday. This front
will return northward as a warm front during the day Wednesday.
A cold front will move through the area late next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
Ongoing convection over central and southern PA has started to
dwindle in terms of intensity this evening, as was expected.
Given the loss of instability, don`t expect much to make it into
our area. What does survive will likely be showers with perhaps
a few rumbles of thunder. So, have decreased POPs a bit with
this cycle, but kept a slight chance for thunder. With all of
the lingering clouds over the region and strong warm advection,
lows tonight will only drop into the upper 50s for most.

.SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY NIGHT/...
A lee-side trof will develop ahead of the main frontal zone
dropping south from Pennsylvania. Almost all guidance have
convection developing south of Spotsylvania County into AKQ`s
CWA. SPC DY2 Otlk has a Marginal risk across the Charlottesville
and Fredericksburg areas. Cdfnt/dewpoint discontinuity line will
drop across the area after 00Z Tue. Dry weather is expected Mon
night with some moisture return into our southwest Tuesday
afternoon. Temps will cool down Tuesday after a day in the 80s
Monday.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Warm front approaches the area on Wednesday, leading to an
increase in dewpoints across the area into the 50s to low 60s.
Increasing PoPs Wednesday afternoon, especially across the
northern half of the CWA where better forcing and moisture
availability will reside. Could be a few rumbles of thunder but
severe chances have dropped over the last several days with the
lack of instability across the area. Highs will be in the low to
mid 70s for most areas for the afternoon. By Thursday, a cold
front is expected to cross the area, leading to additional
chances for showers and few isolated thunderstorms for the
afternoon. A secondary cold front approaches by Friday, leading
to increasing chances for showers again and even going into the
weekend. Impacts should be pretty tame, with mostly just
appreciable rainfall for the end of the workweek into the
weekend with highs in the 70s for the afternoons.

&&

.AVIATION /01Z MONDAY THROUGH FRIDAY/...
-- Changed Discussion --
Slight chance of showers reaching MRB later this evening. Winds
out of the southwest this evening will turn out of the northwest
on Monday, with gusts up to 20 kt. Showers and an isolated
thunderstorm are possible, mianly at CHO Monday afternoon as
well, which could briefly cause restrictions. However, not
confident enough to include in the TAF at this time.

VFR conditions and light winds expected on Tuesday.

Brief sub-VFR conditions are possible Wednesday into Thursday as
showers and a few isolated thunderstorms may approach the terminals,
especially for the afternoon hours.

.MARINE...
-- Changed Discussion --
Small Craft winds will continue across the waters through
tonight before diminishing Monday. A Special Marine Warning may
be required Monday afternoon south of Drum Point and Cobb
Island.

No marine hazards are expected on Tuesday as winds will be well
below SCA criteria.

Small Craft Advisories may be needed Wednesday into Thursday for
gusts 20 to 25 knots across the waters, especially in the
afternoon hours. Additionally, cannot rule out an SMW Wednesday
afternoon/evening as a few thunderstorms could approach the
waters.
