Synopsis
Weak low pressure just off the mid atlantic coast late this
morning, will push northeast toward the northern atlantic this
afternoon. High pressure will build back into the region this
afternoon through Friday, as low pressure lingers off the
southeast coast. Another cold front crosses the area Saturday
and Saturday night, with high pressure building back in from the
west early next week.

Near term until 6 am Thursday morning
Late this morning. Weak low pressure (~1011 mb) was centered
just off the NE nc coast. Latest radar showed last of the
showers just about to move offshore. Latest satellite picture
showed the back edge of the clouds pushing thru the ERN third of
the area, with mainly a clear sky over the remainder of the cwa.

That low will lift NE twd the NRN atlc this aftn, as high
pressure builds in from the wnw. Expect a mostly sunny sky over
the entire region this aftn, and with lagging caa, temps will
rise into the upper 50s north to the lower to mid 60s se.

Mostly clear tonight with caa. Lows coldest NW where mixing
wanes late. Lows in the mid 20s there, upper 20s to lower 30s
much of central va and the md eastern shore, and in the upper
30s around 40 far se.

Short term 6 am Thursday morning through Saturday
Good model consensus for thanksgiving day and Friday, with ~1025
mb sfc high pressure progged to be centered over the oh tn
valley early, then settling over the local area by aftn and
through Friday as low pressure will be well south over the gulf
of mexico. This high keeps the moisture coming off of florida
south of the cwa. Mostly clear and cool Thu thu night and fri.

With fairly limited shallow mixing both days and very dry
conditions (dew pts mainly in the 20s), went on the cold side of
guidance both for highs Thu Fri and for lows Thu night fri
morning. This yields highs thanksgiving day mainly in the upper
40s around 50 f (lower 50s NE nc), lows Thu night Fri in the
upper 20s to lower 30s and highs Fri mainly in the mid 50s
(upper 50s se). Next upper trough moves into the great lakes fri
night sat. Still looks like bulk of moisture from the low to
the south will stay over the gulf stream as it lifts nne. Some
increase in clouds Fri night sat, but will have just a 20% pop
along albemarle sound in NE nc, dry elsewhere. Milder Fri night
with lows in the mid 30s inland to the lower-mid 40s NE nc
coast. Highs Sat upper 50s to lower 60s.

Long term Saturday night through Tuesday
The next cold front crosses the area late Sat sat night. Not
much in the way of moisture to work with (as it stays offshore), but
will carry slight chc pops NE sections of the CWA as upper level
shortwave passes by Sat night. Lows in the mid 30s- lwr 40s.

Dry and colder early next week as a 1025mb canadian high slowly
moves SE across the region. Trends are for this high to be a
little weaker and with less cold air, so have bumped temperatures
up a bit from previous forecast. Highs Sun upper 40s- lwr 50s.

Lows Sun night mid 20s- lwr 30s. Coldest day Mon with highs in
mid 40s to around 50 f. Lows Mon night mid 20s- lwr 30s. Highs
tue in the 50s.

Aviation 20z Wednesday through Monday
Vfr conditions expected at the TAF sites thru the TAF period.

Low pressure will continue to move away into the NRN atlc this
aftn into tonight, while high pressure builds in fm the west.

Nnw winds will gust to 15-20 kt thru this aftn, then diminish
this evening as the high moves closer to the area. High pressure
will maintainVFR conditions Thu thru fri.

Marine
A cold front has moved offshore and will continue to head out to sea
this afternoon through the evening. High pressure builds back into
the area for thanksgiving day and Friday.

Small craft advisories are in effect for all the waters except for
the rappahannock river, york river, and upper james river.

North northwest winds will continue to increase this afternoon as
cooler air works into the region behind the front. Winds of 15 to 25
knots with gusts up to 30 knots can be expected through tonight.

Waves of 3 to 4 feet in the chesepeake bay and seas of 4 to 7 feet
are expected.

Winds will diminish late tonight into Thursday morning as cool high
pressure builds into the area. Sub-sca conditions are then expected
thanksgiving day and Friday with high pressure in the region. The
next cold front crosses the region Saturday night bringing the
potential for gusty NW winds SCA conditions for Sunday. &&

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
