What forecasters said that day
The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Baltimore/Washington wrote its last area forecast discussion before this gale warning went out at Oct 27, 9:22 PM EDT, 3 hours 2 minutes earlier.
Area forecast discussion, Oct 27, 9:22 PM EDT, 3 hours 2 minutes before
Area Forecast Discussion
National Weather Service Baltimore MD/Washington DC
922 PM EDT Wed Oct 27 2021
.SYNOPSIS...
Surface and upper-level ridging builds across the region today into
Thursday. Strong low pressure system builds into the area by late
Thursday Night into Friday from the southwest, bringing several
potential impacts to the area.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Weak high pressure is settling over the area this evening. Winds
have been steadily declining from a combination of nocturnal
stabilization and lesser influence from strong low pressure off
the coast. Some stratus clouds exist on the fringes of the CWA:
moisture from the Great Lakes banked against the western slopes
of the Appalachians in northwest flow; and moisture on the outer
fringes of the offshore low across southern Maryland. Other
than these locations, the night should be mostly clear until
some cirrus start increasing late ahead of the next trough.
Temperatures in most locations will be in the 40s, with some 30s
possible in the mountains/deeper valleys, and lower 50s in
urban centers/nearshore areas.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
Thursday morning looks to have fairly tranquil conditions aside from
clouds continuing to build in from the SW. High pressure will still
be nearby early Thursday before a large upper-level trough out west
of the area produces a cut-off low that will begin to move into the
area. An associated intense surface low will progress northeastward
Thursday, during the day. An attached warm front will move through
the area late Thursday, bringing an initial wave of moisture into
the southwest zones by Thursday night.
The bulk of the precip appears to come through during the day on
Friday from SW to NE in the area. 12z guidance has come in a bit
wetter for the period, with 1-2.5 inches expected across much of the
area on Friday. A Slight Risk for excessive rainfall is present
during the day on Friday. Flood Watches may be needed for more
sensitive areas on Friday. Expect precipitation to last into
Saturday morning before conditions begin to vastly improve.
In terms of potential severe weather, the threat looks to be fairly
minimal with a stable airmass expected ahead of the system passage.
The other impact for the system would be increased winds for much of
the day on Friday. With impressive onshore flow wind fields, some of
the higher terrains may see gusts 40 to 50 knots. High Wind
Watches/Warnings are possible for these higher elevations on Friday.
With water temperatures still being a bit warmer than the surface
temps, winds will mix down a little easier over the waters and lead
to increase potential for Gale-force winds across all of the waters
on Friday.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
A large area of low pressure at the surface and aloft will be
overhead Saturday, resulting in cloudy skies and elevated shower
chances. Temperatures will hover near to slightly below normal
during this time thanks to the increase in clouds and rain chances.
The axis of the upper low will begin to lift northeastward Saturday
night into Sunday, as rain chances diminish with high pressure over
central U.S. building eastward. Weak high pressure will be in
control Monday with dry and seasonable conditions before the next
frontal system approaches to our northwest Tuesday, bringing an
increase in rain chances and temperatures remain near normal.
&&
.AVIATION /01Z THURSDAY THROUGH MONDAY/...
Weak high pressure is settling over the area tonight, with
north/northwest winds becoming light and variable by night's
end. VFR conditions expected through tonight and into most of
the day on Thursday with lighter winds out of the northeast. A
potent low pressure system will begin to move in from the
southwest Thursday night. Expect ceilings gradually lowering to
MVFR during the evening, although there is some uncertainty how
quickly this will occur (and it could be possibly earlier at
CHO).
The most impactful period will be late Thursday night through
Friday evening. MVFR to IFR conditions are expected due to low
ceilings and occasional moderate to heavy rain. Thunderstorm
chances are low but non-zero. Strong easterly winds will peak
during the day on Friday, although low level wind shear could
become a factor when nocturnal cooling or heavier rainfall
stabilizes surface conditions.
Sub-VFR conditions are likely at all terminals Saturday as low
pressure at the surface and aloft settles over the terminals,
resulting in plentiful cloud cover, increased rain chances and light
southerly winds. Conditions are expected to improve late Saturday
into Sunday as the system lifts northeastward and winds turn out of
the west northwest.
&&
.MARINE...
Winds are largely diminishing this evening and therefore
cancelled the Small Craft Advisory early on the narrower
waterways. Contemplated doing so elsewhere too, but some models
indicate there could still be a few more pulses over the next
few hours. Higher confidence winds stay below 15 knots late
tonight.
High pressure briefly moves in overhead late tonight and into early
Thursday, leading to a brief drop in winds across the waters and sub-
SCA conditions. Low pressure system moves in by late Thursday night,
leading to increased winds across the waters by early Friday. With a
strong onshore flow in place, a Gale Watch is in effect for all of
the waters from Friday morning through Friday evening.
Light southerly breezes are expected across the waters Saturday as
low pressure tracks across the region. Winds will turn out of the
west northwest by Sunday as the system lifts to our north, with SCA
conditions possible in its wake.
&&
.TIDES/COASTAL FLOODING...
A strong onshore flow is expected to develop across the waters
Thursday afternoon, then strengthen Thursday night through Friday as
low pressure tracks toward the region. The strongest winds are
expected during the Friday afternoon and evening timeframe, with the
potential for moderate tidal flooding during this time and into
Saturday morning. Major flooding can't be ruled out, especially
at Straits Point/St. Marys. Due to the wind direction, the
northern reaches of the bay may be spared the worst of the
surge, but minor flooding is still possible.
Based on the latest forecast, Coastal Flood Watches were
expanded to a few more zones, although confidence is generally a
little lower in these areas (Baltimore, ungauged upper Potomac
areas). It is still worth pointing out that this could be one of
our more significant coastal flood events in recent years, and
anyone with shoreline interests/properties should consider
preparing for the potential of tidal flooding. Continue to
monitor the latest forecasts as the picture becomes clearer over
the next 24 hours. On top of that, water levels will only fall
slowly through the weekend as the responsible low pressure won't
depart until later Sunday.
