Synopsis
High pressure will remain over the region through Friday. Low
pressure will linger off the southeast coast Friday through
Saturday morning. Another cold front will cross the area late
Saturday into Saturday night, with high pressure building back
in from the northwest Sunday and Monday.

Near term until 6 am Friday morning
Latest wx analysis reveals broad area of surface high pressure
extending from the western gulf coast into the NRN mid atlc
region. Aloft, a trough axis was in place from the ERN great
lakes south into the gulf of mexico. To the south, a weak
surface low pressure lifting NE over central fl.

Only minor changes needed to the grids on this thanksgiving
evening. Surface high pressure will remain in control through
the overnight, keeping moisture associated with low pressure
over fl shunted off to our sse, although we'll continue to see
some sct-bkn cirrus over SE sections through this evening.

Adjusted lows down slightly with temperatures already in the
upper 20s to low 30s inland. Early morning lows will range fm
the low-mid 20s far NW to near 30 most areas (lower to mid 30s
over coastal SE va and NE nc).

Short term 6 am Friday morning through Sunday
Latest GFS nam ECMWF remain in good agreement with the pattern
through the weekend, with enough northern stream trough energy
passing by to our NE Fri morning aftn to keep sfc low pressure
and associated moisture off the SE and mid atlc coasts and
sse of the local area. Sfc high pressure more or less to stay
entrenched over the region thru fri, gradually shifting off the
mid atlc coast Fri evening night. Bufkit soundings again depict
fairly limited shallow mixing for fri, so even with significant
rises in 850 mb temps, actual high temperatures at the sfc will
not warm all that much, mainly into the mid 50s. Mostly sunny,
except for some increasing clouds over the far se.

Next upper trough moves into and thru the great lakes fri
night sat. Still looks like bulk of moisture from low pressure
off the SE and mid atlc coasts stays well ese and offshore, as
it lifts ene. Not quite as cold Fri night with lows mostly
ranging fm the mid 30s to around 40. Sfc cold front approaches
from the west late Fri night into midday sat, then crosses the
area late Sat into Sat night. A SW flow to develop and will see
a milder day with highs around 60 N to the mid 60s se. Clouds
will increase during the aftn, and become mostly cloudy across
the nw. Sfc cold front and a lagging shortwave trough aloft to
cross the region Sat evening and push offshore Sat night. System
remains moisture starved, but will carry 20% pops over the N ne,
gfs is stronger with the forcing than the ecmwf. Lows Sat night
ranging fm the mid 30s NW to the lower 40s SE va and NE nc.

Mostly sunny and turning cooler sun, as sfc high pressure
returns fm the w. Highs mainly 50-55.

Long term Sunday night through Thursday
Medium range period characterized by departing east coast trough,
and building upper level ridge over the rockies sliding east through
midweek. Temperatures will be slightly below climo to start the
period, but will moderate through the period, warming back into the
60s for mid to late week.

Rain chances remain low through Wednesday, with low chance pops by
Thursday as a southern stream system pushes east from the southern
plains toward the southeast Wed night thu.

Aviation 01z Friday through Tuesday
Vfr conditions expected this aftn into Fri aftn with just some
sct-bkn high clouds thru the period, esply at phf orf ecg. North
winds 5-7 kt early this aftn, will become light variable by
early this evening. Sfc high pressure will maintainVFR
conditions into sat. Winds will strengthen a bit from the ssw
sat ahead of a cold front, and turn to the NW for Sat night and
sun, with high pressure building back in from the wnw. Sky may
become mostly cloudy Sat aftn evening, with isolated showers
possible, butVFR conditions will prevail.

Marine
High pressure will remain over the region tonight, and then
gradually slides off the mid-atlantic coast Friday. Meanwhile,
low pressure will linger off the southeast coast. This area of
low pressure will gradually push farther offshore Friday night
into Saturday, as a cold front approaches from the NW by
Saturday. The wind will be northerly AOB 10kt for much of the
marine area tonight, but will become NE 10-15kt S of CAPE henry
late tonight. The wind will gradually become NE then E Friday,
with speeds AOB 10kt, before becoming SW 10-15kt late Friday
night into Saturday ahead of the approaching cold front. Seas
remain 3-4ft tonight into Friday and then subside to 2-3ft
Friday night into Saturday. The cold front crosses the region
Saturday night followed by a subsequent CAA surge late Saturday
night into midday Sunday with a NW wind of 15-25kt. Seas build
to 4-6ft, with 3-4ft waves in the bay. High pressure returns
Sunday night into Monday and then slides off the southeast coast
Tuesday.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
