Synopsis
Canadian high pressure prevails over the mid-atlantic region
overnight and Friday. A cold front crosses the area Saturday.

Another canadian high pressure system builds into the region
Sunday.

Near term until 6 am Friday morning
As of 725 pm edt Thursday...

no major changes to the going forecast, with only minor digital
database modifications per latest obs. 1034mb high pressure is
centered over the eastern great lakes interior northeast and
continues to building east to the mid-atlantic. Clear sky and
light wind will allow temperatures should drop quickly this
evening over the next few hours as the wind becomes calm to
very light under a clear sky, with ideal radiational cooling
conditions overnight. Forecast lows are in the low mid 30s for
the piedmont, interior coastal plain, and interior md ERN shore.

A frost advisory will go into effect late tonight for much of
central e-central va and the md ERN shore, mainly for rural
areas, and away from the immediate coastlines, where the best
potential for frost is located. Farther se, patchy frost is
still possible for interior NE nc, and rural SRN wrn portions
of the tidewater. Some typically favored cold spots could have
a light freeze over the NW piedmont. Elsewhere, lows should be
in the upper 30s to low 40s, with mid 40s at the coast in se
va NE nc.

Short term 6 am Friday morning through Sunday
As of 400 pm edt Thursday...

high pressure gradually slides offshore by Friday aftn. Mostly
sunny with highs in the low to mid 60s. A cold front approaches
from the NW Friday evening, and pushes across the region late
Friday night through midday Saturday, and into Saturday aftn for
the ERN third of the area. Pops are ~60-70% for a period of
rain across the piedmont and central va late Friday night into
early Saturday morning, then into the ERN shore, SE va, and ne
nc Saturday morning through midday. Pops then taper to 20-40% in
the aftn for showers over e-central va, the ERN shore, and ne
nc. QPF of 0.25" or less is expected for most of the area, with
0.25-0.4" for far SE va NE nc. Milder Friday night with lows in
the 50s, with highs in the upper 60s to around 70f Saturday.

A potent NRN stream trough digs across the region Saturday
night into Sunday. This could result in some lingering sc over
the NRN neck ERN shore Saturday night. Otherwise, drier cooler
air will arrive from the nw. Forecast lows Saturday night range
from the low 40s NW to the upper 40s low 50s far se. Cool,
mostly sunny, and a breezy NW wind Sunday with highs in the mid
50s NW to low 60s se.

Long term Sunday night through Thursday
As of 400 pm edt Thursday...

after persistent low-level CAA during the day on Sunday,
~1030mb sfc high pressure settles over the western half of
virginia Sunday night. With clear skies and light winds, expect
a cold night across the area, with temperatures possibly
approaching a 32f over a few inland locations (most likely over
the western cwa) early Monday morning. Low temperatures will
range from the low-mid 30s inland to the 40s along the immediate
coast.

The area of high pressure quickly moves offshore on Monday.

This will allow winds to turn back to the south, setting the
stage for a very modest warm-up early next week. The warm-up
will be short lived, as low pressure (sfc-aloft) passes to our
north on Tue tue night. This will drag another cold front
through our area late tue- wed. The latest 18 12z suite of
guidance continues to (strongly) suggest a dry fropa. Highs in
the upper 50s-low 60s on Mon will rise into the mid 60s
nw around 70 SE on tue. Morning lows will be in the upper 30s-
mid 40s on tue. Behind the front, sfc high pressure moves from
the great lakes to the mid-atlantic northeast on Wed thu. This
setup will likely keep our temperatures below seasonal averages
from mid-late next week. Forecast highs on Wed are in the low-
mid 60s, cooling to the mid 50s-low 60s on thu. Rain chances
potentially make a return to the area Thursday night into next
weekend, as models are hinting at the development of low
pressure off the southeast coast.

Aviation 23z Thursday through Tuesday
As of 725 pm edt Thursday...

cool continental high pressure over the ohio valley continues
to spill east over the region. This will bring continued clear
sky light winds andVFR conditions across area terminals through
the 00z TAF period. High pressure slides offshore Friday with a
sw wind of 5-10kt developing later in the morning through the
aftn. Mostly sunny with some increasing high clouds later in the
aftn.

Outlook: another cold front approaches from the NW Friday
evening and moves through the area late Friday night into
Saturday. This will bring a period of mainly light rain, along
with the potential for a period of lower CIGS vsby. Breezy
conditions are expected by Sunday in a NW wind behind the cold
front. High pressure returns Monday and slides offshore Tuesday.

Marine
As of 400 pm edt Thursday...

latest analysis shows high pressure building across the region
and thus a decreasing gradient. As a result, winds have
continued to diminish through the afternoon hours thus small
craft advisories for the bay have been cancelled. A rogue gust
to 20 knots may still be possible at elevated sites through the
late afternoon, but the trend is for diminishing winds. For the
coastal waters, scas remain in effect for the southern waters
mainly due to seas in excess of 5 feet. As with the winds, seas
will also decrease through the afternoon and evening hours.

Expect N winds around 5-15 knots tonight into Friday before
becoming S later in the afternoon and evening. Seas will
diminish to 2 to 3 feet and waves 1 to 2 feet.

High pressure eventually shifts offshore as we head into Friday
evening and overnight. The flow will become ssw overnight
Friday into Saturday morning, 15 to 25 knots, and scas will
likely be needed for at least the bay. The next cold front
crosses the waters Saturday night into Sunday, bringing with it
a surge of NW winds of 15 to 25 knots with gusts potentially in
excess of 30 knots. Sunday morning will need to be watched
closely as gale gusts may be possible over the coastal waters.

Hydrology
As of 725 pm edt Thursday...

river flood warning has been lowered for the appomattox at
matoaca, but still continue on for the nottoway river at
sebrell. See flsakq for site-specific details.

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.
