Synopsis
Weak low pressure tracks northeast along the carolina coast
early this morning, then pushes well off the mid- atlantic
coast later today as a cold front moves offshore. High pressure
builds 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 through tonight
Moisture continuing to stream N from the SE CONUS coast into the
local area early this morning. Scattered to numerous showers
over central and eastern va and the md eastern shore, with lower
coverage in SE va. Latest radar suggests showers fill in enough
for at least a few hrs between now and 12z for likely pops all
areas east of i-95, and categorical for the md eastern shore
towards daybreak. Made these updates in the gridded forecast.

Temperatures fall only a few degrees through 12z for lows to the
mid-upper 40s W NW to the lower-mid 50s near the coast.

Low pressure progged to track NE off the va capes later this
morning and with the cold front moving offshore. Any lingering
showers look to move offshore after 15z. Column begins to dry
out west to east Wed as high pressure builds in from the wnw.

Mostly sunny west, becoming mostly sunny east by aftn. Lagging
caa, a mild start and aftn sunshine allows for high temps to
rise into the upper 50s north to the lower-mid 60s se. Mostly
clear tonight with caa. Lows coldest NW where mixing wanes
late... Lows in mid 20s there, upper 20s lower 30s much of
central va, and upper 30s around 40 f far se.

Short term Thursday 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 mositure 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 09z Wednesday through Sunday
Scattered to numerous showers to overspread terminals over the
next few hrs, with brief MVFR ifr vsbys possible in heavier
rain through 09z. CIGS gradually lower to 1500-2500 ft and
possibly down to ifr thresholds along the coast towards 12z. In
general have include a 2-3 hr period with tempo ifr conditions
(mainly vsbys) at area TAF sites at some pt from 08-12z.

Lingering low CIGS vsbys possible along the coast from 12-15z,
otherwise drying of the column will result in decreasing clouds
through the day with all TAF sites becomingVFR by 15-18z. Winds
shift to the nnw behind the cold frontal passage and will gust
to 15-20 kt through late morning and the aftn.VFR conditions
expected for the rest of the week as high pressure builds into
the region from the w.

Marine
Weak low pressure will track northeast just off the coast this
morning ahead of a cold front. The cold front is expected to move
offshore by 10 am. High pressure builds back into the area for
thanksgiving day and Friday.

Scas remain in effect for all the waters except the rappahannock
river, york river, and the upper james river. S-se winds 5-15 kt
early this morning will become NW then N and increase to 15-25 kt
with gusts up to 30 kt from late this morning into tonight. Waves
will build to 3-4 ft in the ches bay, and seas will build to 4-7 ft.

N winds will diminish late tonight into Thu morning, as cool high
pressure builds into the region. Sub-sca conditions then expected
thanksgiving day and Fri with high pressure nearby.

Equipment
Kdox remains down. Parts are on order and are expected to arrive wed.

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.
