Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
237 PM EST Sun Nov 27 2022
.SYNOPSIS...
Early rain this afternoon will exit as a low pressure system moves
further north and east. The associated cold front will move through
late tonight through early Monday morning. High pressure returns
Tuesday before moving offshore Wednesday. Strong cold front
approaches by early Wednesday into Wednesday night, bringing
increased rain chances and gusty winds in its wake. High pressure
returns late in the week.
&&
.NEAR TERM /THROUGH TONIGHT/...
Mid-morning to early afternoon widespread rain has begun to
subside over the area with only some residual light rain in the
wake of the warm sector of a low pressure system that is moving
off to the northeast. Visible satellite and local METARS show a
low cloud deck across the eastern two-thirds of the CWA. As the
more potent rain shield moves further offshore, a lingering
cloud layer remains in the area, especially east of the Blue
Ridge Mountains. A strong line of showers, capable of lightning
are in the RLX/PBZ forecast areas. These showers may approach
western MD over the next hour or so and bring increased gusty
winds with a convective element to them, will be worth
monitoring over the next hour or so. A few stray showers will
linger through the afternoon before dissipating later this
evening. The only exception to this will be along the Allegheny
Front, where low-level moisture will continue throughout much of
the night. Areas mainly above 3k feet will likely see some
light, accumulating snow showers through Monday morning.
Temperatures will be dependent on how much cloud cover is broke
in a particular area. For example, Petersburg, WV will likely
downslope and get into the mid 60s for a high whereas areas just
outside of there will see upper 50s.
The other story for today is the winds, especially along the western
fringe of the CWA. Gusty southwesterly winds remain possible through
the evening in these areas with gusts up to 50 mph. A Wind Advisory
remains in effect for the aforementioned areas through the overnight
hours. There have already been 45+ knot gust observations just west
of the Allegheny Front early this afternoon.
As the rain chances decrease for most areas later this evening, the
winds will decrease east of the Blue Ridge while strengthening out
west and along the ridges throughout the night as the pressure
gradient continues to remain fairly tight. Overnight lows will be in
the 40s to low 50s for most areas (upper 20s to 30s for higher
elevations).
&&
.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
An upper-level trough axis will likely follow behind the trailing
cold front associated with the low pressure system on Monday.
Lingering low-level moisture will allow for rain/snow showers mainly
along and west of the Allegheny Front during the day on Monday.
Highs will be cooler compared to Sunday with the mountains likely
only seeing the 30s and 50s elsewhere. Winds will continue to be
elevated across the area but will likely be below wind advisory
criteria.
An area of high pressure will build over the area later Monday,
allowing winds to diminish as the pressure gradient weakens. The
high will begin to move further offshore by Tuesday, but conditions
should remain dry ahead of the next system expected to impact the
area. Moisture will increase ahead of the system Tuesday night and
allow for increasing clouds from west to east with some light rain
likely overspreading the western areas after midnight-1AM Wednesday
and moving east by early Wednesday morning.
&&
.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
A split flow pattern is expected to remain over the CONUS heading
into the middle of the week as a trough moves over the Plains and
broad ridging builds over the Southeast. As the trough progresses
eastward into the Great Lakes, an associated cold front is expected
to approach the area. This will bring rain to the region.
By Thursday morning, although some models still have lingering
upslope showers into the afternoon, most of the region should be
dry. The main concern Wednesday into Thursday continues to be the
threat for strong/damaging winds. Models continue to show a strong
surge behind the front Wednesday into Thursday.
Following the exit of this system, high pressure is expected to
build into the region once again to close out the week.
Temperatures during the period start out above normal, with
Wednesday being the warmest day ahead of the cold front. Behind the
front, temperatures drop to below normal briefly before warming
through the end of the week.
&&
.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
IFR to sub-IFR conditions will continue through at least 21z for the
eastern terminals. Latest satellite shows clearing out west that
will likely move further east over the next several hours and
improve to MVFR/VFR CIGs/VISs. If winds are able to calm across the
eastern terminals tonight, then some fog/low clouds may reform this
evening and into tonight.
Low-level wind shear is also in the forecast through this afternoon
as the low-level jet strengthens.
A cold front will pass through the terminals late tonight into early
Monday. A stratocu deck is expected behind the cold front, but cigs
should be just above 3kft for most areas. High pressure will build
overhead Monday night into Tuesday. SubVFR conditions and
precipitation chances may return late Tuesday night ahead of the
next cold front, which will be a strong cold front.
Sub-VFR conditions are likely and LLWS is possible as a strong
frontal system impacts the area Wednesday into Thursday. This system
may also bring strong wind gusts in excess of 30 knots with a wind
shift to the W/NW as it passes.
&&
.MARINE...
Gusty showers have crossed the waters over the last hour or so and
led to a few upper 20 to low 30 knot gusts within these showers.
This will likely continue through the evening as the low-level jet
strengthens. The SCA remains in effect this evening for the waters
and for late tonight over the Bay and lower Tidal Potomac River.
Southwest winds are expected during this time. A cold front will
pass through the waters late tonight into early Monday morning, and
gusty northwest winds are expected behind the boundary. An SCA is in
effect for all of the waters Monday, and may need to be extended
into Monday night for portions of the waters. High pressure will
build overhead late Monday night into early Tuesday before moving
offshore later Tuesday. A strong cold front will approach from the
west Tuesday night. Southerly winds will increase, and an SCA may be
needed for portions of the waters during this time.
Gusty southerly winds are expected Wednesday, becoming westerly to
northwesterly Wednesday night into Thursday as a strong cold front
crosses. Gale conditions are possible during this time.
&&
.TIDES/COASTAL FLOODING...
A southerly wind will increase today into this evening ahead of a
cold front approaching tonight. This will cause anomalies to
increase sharply, since gusty southerly winds are expected (20-30
knots). Minor flooding is possible around times of high tide,
especially late this afternoon and tonight across the northern half
of the Bay from Annapolis northward. However, the flow will turn
west of south during this time, so that does lower confidence
some.
