Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
257 PM EDT Thu May 11 2023
.SYNOPSIS...
High pressure will gradually move east and offshore through
Friday. Low pressure moves into region late Friday into
Saturday along a stalling frontal boundary. The front will push
south by Sunday, although another system may approach the area
early next week, followed by high pressure around midweek.
&&
.NEAR TERM /THROUGH TONIGHT/...
High cirrus currently streaming over the region is expected to
increase in coverage through the day. A few patches of cu have
developed as well, primarily along terrain and in north central
MD. Latest CAMs have backed off from producing any showers this
afternoon, consistent with prior forecast.
Surface high pressure continues to move eastward out
of the area, bringing warm return flow out of the south.
Temperatures are on track to reach into the upper 70s to low 80s
this afternoon. Lows tonight are expected to be in the 50s
across the area. Fog is possible tonight, primarily for areas
west of the Blue Ridge.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
As high pressure at the surface exits to the east, a shortwave
trough is expected to move into the Ohio Valley and weaken the
upper ridge overhead. The shortwave approaching the area will
bring more unsettled conditions with increased cloud cover and
shower chances. There are still some inconsistencies regarding
timing and the track of the shortwave, but generally chances for
scattered showers and thunderstorms increase heading into Friday
afternoon. The best chance for precip during the afternoon will
be in our southwestern zones, with lower chances to the
northeast.
A frontal boundary is expected to stall over the region Friday
night into Saturday while the shortwave is progged to track
along it. Coverage of showers and thunderstorms increases during
this time frame as a result. Timing of precip exit on Saturday
will be dependent on a cold front descending into the area from
Canada and when that moves through, pushing precip out and
bringing drier conditions. Currently, the most likely time frame
for this looks to be late Saturday evening into Saturday night.
Temperatures will be dependent on the timing of features moving
through the area, but for now generally expect highs in the
upper 70s to low 80s on Friday, cooling into the upper 60s to
low 70s on Saturday with cloud cover and precip.
&&
.LONG TERM /SUNDAY THROUGH THURSDAY/...
The stalled front that will have impacted the area for the weekend
will continue to push further southeast of the region by late
Saturday/early Sunday, with high pressure building in its wake. A
few lingering showers and sprinkles will be possible early Sunday,
mainly across the higher elevations of the Allegheny Front.
Otherwise, mostly dry conditions will settle across the area. A weak
shortwave will cross on Monday and may bring some limited shower
activity, especially across central VA and southern MD. Nonetheless,
QPF totals will be minimum given the amount of available moisture
with this system.
A weak front approaches Monday into Tuesday, with
slightly cooler air ahead of it on Monday before southerly flow
rebounds on Tuesday with highs in the upper 70s to low 80s expected
across most of the lower elevations. High pressure builds in further
by midweek, leading to dry conditions with fairly light winds
expected.
&&
.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
High pressure maintains VFR conditions today with light winds
out of the S/SW. MVFR conditions are possible for MRB late
tonight into Friday morning with any fog that may develop near
the terminal.
Precip moves into the area starting Friday afternoon in our
southwestern zones, becoming more widespread overnight and into
Saturday. MVFR to IFR conditions are possible with any showers
and thunderstorms in this timeframe. Precip decreases in
coverage and moves out Saturday afternoon into Saturday evening
as a cold front moves through.
VFR conditions are expected Sunday and Monday with only a few
showers possible, mainly across the southern terminals. MVFR
conditions may briefly build in during this time but duration is
expected to be quite low given the setup. A weak front builds
in late Monday, which should clear conditions even more and lead
to ample VFR conditions through midweek.
&&
.MARINE...
Sub-SCA conditions are expected during the day today with high
pressure over the waters. A Small Craft Advisory has been issued
from 6PM tonight through 6AM Friday morning for the southern
waters. Gusts around 20kt are expected with southerly
channeling. SCAs may be needed Friday night for southerly
channeling as well, but gusts seem marginal. Showers and
thunderstorms over the waters Friday night into Saturday as a front
stalls over the area. A cold front is expected to push through
Saturday evening, bringing drier conditions. As the front moves
through and winds increase out of the N/NW, SCA conditions are
possible.
High pressure will build in late in the weekend and into early
midweek, likely keeping winds down for the period across the waters
to below hazardous.
