Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
234 PM EDT Sat Apr 19 2025

.SYNOPSIS...
A cold front will move through the area today as high pressure
builds to the north. The cold front will stall to the south Sunday
before lifting as a warm front on Monday. A low pressure system
tracks across the Great Lakes on Monday with the associated cold
front swinging through the mid-atlantic Monday night into Tuesday.
High pressure builds to the north on Wednesday ahead of a nearby
front bringing precipitation chances at the end of the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
A positively tilted trough is currently tracking across central
CONUS while pushing a cold front draped from Texas to the Great
Lakes eastward. Current radar imagery as of 1:30PM shows
convection tracking ahead of the cold front into New England.
The majority of CAMs have convection primarily staying north of
the forecast area in PA, however, CAMs continue to show showers
and thunderstorms impacting western MD late this evening. SPC
has western MD in a marginal risk for severe weather this
evening with the primary threats being damaging winds gusts.
Outside of western MD, cloudy skies and dry conditions are
expected through the overnight.

The cold front will approach the forecast area this evening,
before dropping through from northwest to southeast overnight.
Winds shift to northwesterly late tonight behind the front.
Outside of shower activity in the northwestern portions of the
forecast area, dry conditions continue overnight. Low
temperatures will be in the 60s for most with higher elevations
staying in the 50s.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
Surface high pressure builds to the north tomorrow with primarily
dry conditions expected. The exception will be west of the Blue
Ridge and south of US-50. The aforementioned cold front will be
stalled to our south, however, the proximity of the front combined
with peak daytime heating may result in showers and thunderstorms in
that area. Should convection initiate, the greatest threat would be
hail given the low freezing levels and mid-level shear. High
temperatures will be in the 70s to low 80s for most with those at
higher elevations staying in the 60s. Overnight low temperatures
will be in the 50s.

On Monday, a low pressure system tracks northeast across the Great
Lakes with the associated cold front approaching the forecast area
from the west. The aforementioned front to the south, will lift
north through the Mid-Atlantic as a warm front ahead of the low
pressure system. During the day, dry conditions are expected with
high temperatures in the 70s to low 80s. Those in NE MD and/or
at higher elevations will stay in the upper 60s. Precipitation
chances increase from northwest to southeast overnight as the
cold front approaches. Low temperatures will be in the 50s to
low 60s.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
A cold front draped over the area early Tuesday will be pushed
south during the afternoon by a reinforcing upper trough. Scattered
showers and some thunderstorms are possible Tuesday, mostly
along/south of I-66/US-48. Very warm conditions as highs reach the
upper 70s to low 80s. While the cold front is forecast to move into
southern VA, there could be some lingering showers in Central VA
Tuesday night into Wednesday morning.

Beyond that, a surface high over the region brings dry conditions
Wednesday afternoon into Thursday. Highs in the 70s to low 80s for
the middle of next week, with overnight lows in the 50s to around
60F. Another cold front approaches late Friday and brings the next
round of showers and possible thunderstorms.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
West/southwest winds continue this evening, with gusts diminishing
after sunset. Light winds are expected overnight as a weak cold
front pushes through the forecast area. Winds shift to northwesterly
behind the front overnight. On Sunday, high pressure shifts to the
north, with northerly winds shifting to easterly winds throughout
the day. VFR conditions are expected across all terminals today and
Sunday. On Monday, winds shift to southeasterly resulting in
increased moisture and low level clouds. With primarily VFR
conditions expected, MVFR ceilings are possible.

A cold front sagging south through the area on Tuesday could produce
scattered showers/thunderstorms, though the highest coverage is
likely to be south of most of the terminals. Will have to see for
any impacts at CHO. Otherwise, VFR conditions are likely to prevail
through the middle of next week.

&&

.MARINE...
Small Craft Advisory conditions continue through this evening as a
cold front approaches and moves over the waters. Behind the front,
winds become northwesterly and are expected to diminish to sub-SCA
criteria early Sunday morning. Winds shift to northerly and then
northeasterly on Sunday, before becoming east/southeasterly
overnight. On Monday, SCA criteria winds are possible as winds
channel in southeasterly flow. Winds shift to southerly Monday night
and into Tuesday, with SCA criteria winds continuing in the southern
portions of the Chesapeake Bay.

Favorable marine conditions possible for the middle of next week,
though gusts could approach 15 knots Tuesday afternoon. A cold front
sagging south through the waters through the day on Tuesday could
produce scattered showers and thunderstorms. Any strong storm could
pose a localized hazard to boaters. The front pushes south of the
area Wednesday morning as winds turn north, then east behind the
front on Wednesday afternoon.

&&

.CLIMATE...
Very mild conditions this morning kept low temperatures in the 60s
across the area. If these temperatures hold through midnight local
time tonight (1 AM EDT), there could be several warm minimum
temperature records that are tied or broken. Below is a list of
daily record warm minimum temperatures for April 19, as well as the
observed minimum temperature so far today (as of 2 PM EDT).

Dulles (IAD), Annapolis (NAK), and Hagerstown (HGR) are on pace to
