Synopsis
A strong cold front will push across the area after midnight.

Cold canadian high pressure builds in from the north thanksgiving
day into Friday, bringing well below normal temperatures but dry
conditions to the area. Low pressure impacts the region Saturday
bringing the next chance for rain.

Near term through tonight
As of 345 am est Thursday...

latest surface analysis reveals strong low pressure pulling
across the canadian maritimes this morning. The associated
surface low has pushed across labrador newfoundland, with the
attendant trailing arctic front dropping across the delmarva
toward the local area early this morning, as strong 1038+mb sfc
high pressure builds from ontario and the upper great lakes into
new england northeast CONUS today. Resultant strong cold dry
air advection behind the front will make for a blustery and cold
thanksgiving day across the region. Look for highs only in the
30s today over much of the area (some low 40s possible far
southern tier of counties from us-58 south into nc. Wind chills
will remain in the 20s and 30s through the day.

Record lows and record low maximum temperatures are included in
the climate section below. Temperatures at midnight to 1 am will
prevent any low maxs from being realized today, but expect temps
to remain quite chilly today in strong caa. Mainly clear today,
except for along coastal tidewater, where strong CAA advection
running south across the still- relatively warm bay waters will
result in a few bay streamer clouds per nam-dng and past few
successive runs of the hrrr.

A cold night ahead tonight. Winds should diminish this evening
as high builds to the north and gradient slackens. Expect
temperatures to then plummet into the 20s to low 30s after
sunset into the late evening hours. Have issued a freeze
warning for the small handful of counties that are still active
in the frost freeze program this late in the season, mainly for
coastal tidewater (incl. Orf va beach and NE nc along and east
of edenton), with only the coastal NRN obx not in the freeze
warning. Early morning lows in the upper teens to low 20s
inland... Upper 20s to mid 30s coastal NE nc.

Short term Friday through Saturday night
As of 345 am est Thursday...

dry and a bit milder on Friday. Upper ridge will build over the
region Friday, but will quickly pivot offshore ahead of next
upper trough coming ashore across the ca coast this morning.

This should translate to a clear mostly sunny day Friday (some
increase in low mid clouds possible over the SE from the ocean
and the SW as warm advection aloft ensues). Still, despite
modest moderation, temps will remain chilly with highs only in
the 40s with the cold ridge still in place across the region and
limited mixing.

Previously referenced upper trough across the west coast slides
across the plains and mid-south Friday and Friday night, before
taking on a neg tilt and ejecting northeast across the northern
mid-atlantic into the northeast Saturday into Sat night.

Meanwhile, cool air wedge looks to develop as high pressure over
new england slides offshore, with cool dry air becoming pinned
against the eastern slopes of the central appalachians.

Gradually increasing isentropic lift will allow for light
precipitation to break out toward dawn Saturday morning in the
west, and shortly thereafter toward the coast. For the most
part, quick warming will prevent any significant p-type issues
for most even west of i-95, with temperatures mild enough for
no issues at all along the coast. However, as is typical with
these in- situ wedges, a brief period of sleet or even freezing
rain is possible well inland as the vertical column saturates.

Top-down powt tools indicate usual areas along west of highway
15 are most likely to experience this brief mixed pcpn, and as
with the previous event, minimal (if any) impacts are anticipated,
but will bear further watching. Rain will become moderate to
briefly heavy (especially inland) Saturday aftn, tapering to
light rain drizzle ending from west to east late Sat aftn night,
with the trailing cold front ending all pcpn late Sat night.

Highs Sat in the upper 40s to low 50s NW to mid to upper 60s se.

Long term Sunday through Wednesday
As of 345 am est Thursday...

local area will be in between systems Sunday, with brief
clearing expected across the area. Temps Sun Mon will be
slightly warmer than Thu Friday, and closer to normal with highs
in the upper 50s lower 60s and upper 30s to 40s. Next system
crosses the area on Monday, with another shot of cold air with
a cold front crossing the region later Mon Tuesday. This will
bring temperature back down below normal for the middle of next
week, but condition look to remain mostly dry with best
moisture forcing looking to remain off to our nw.

Aviation 08z Thursday through Monday
As of 1245 am est Thursday...

vfr conditions across area terminals this morning will prevail
through the 06z TAF period and beyond. Some scattered mid level
clouds possible briefly later this morning W bay streamers
(mainly orf, but a chance at sby phf as well), as a strong
cold frontal passage drops across the terminals early this
morning. Winds shift to the N NW overnight then become gusty
at times (15-25 kts) with onset of diurnal mixing after 14-15z
through early evening.

Outlook...

dry WVFR conditions tonight through Friday night. Next
system brings rain and flight restrictions Sat morning through
sat evening. Clearing out withVFR conditions returning for
sun.

Marine
As of 330 am est Thursday...

strong CAA expected today as a cold front pushes south of the local
area this morning. N winds will average 15-25 kt with gusts up to 30
kt most waters thru the day. As such, will leave SCA headlines in
place for all waters save the upper james, york and rappahannock
rivers where winds will remain 15kt or less. Waves 2-4 ft; seas 3-6
ft. N to NE winds diminish this evening and overnight so that scas
for the lower james river, the bay and currituck sound can come down
by or before 10 pm. Seas will gradually subside as well this evening
and overnight, but will be slowest to do so south of CAPE charles.

Therefore, have extended scas for the southern coastal waters thru
Friday morning as seas remain around 5 ft.

Winds veer to easterly at 10-15 knots on Friday as weakening high
pressure to our north moves eastward into the atlantic. Seas around
5 ft may linger along the northern obx. For Saturday, the next storm
system is expected to impact the waters by later in the day.

Southeasterly winds will increase through the day to 15-25 knots by
late afternoon evening with building seas waves. Another round of
scas appear likely for a large portion of the local waters, with
seas being slow to subside into Sunday.

More unsettled marine conditions appear possible early next week.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
