Synopsis
High pressure will move off the southeast coast today. A low
pressure system will pass near the area on Monday, then high
pressure settle southward across the area for Tuesday through
Friday.

Near term until 6 pm this evening
The center of high pressure resides near eastern north carolina
early this morning. Some cirrus clouds are approaching from the
west, but the first part of the day should see plenty of
sunshine. As ridging is suppressed later in the day, additional
mid and high level clouds will arrive. With the surface and
upper ridge axes moving east today, return flow will help boost
temperatures into the 60s for most areas despite the increasing
clouds.

Short term 6 pm this evening through Tuesday night
Vorticity advection and weak isentropic lift ahead of a
shortwave trough approaching from the west will allow clouds to
thicken and lower tonight. Some light rain is possible, mainly
in the potomac highlands and potentially extending eastward
along and north of the us-50 corridor. Any precipitation
overnight should be light as low levels will still be dry. It
should be in liquid form as well with temperatures above
freezing at the surface and aloft.

The main trough axis will be crossing the area Monday afternoon,
with a surface low reflection likely passing south of the area.

At the same time, a cold front of canadian origin will be
slipping southward as it merges with the southern system. The
highest rain chances will be during the afternoon. At this time,
the highest rain totals of a quarter to half inch are expected
to be across southern portions of the area, closer to the better
forcing. The northern gradient of the precipitation shield will
be near the pennsylvania border, so it's not out of the question
a slight shift could leave portions of these areas mainly dry.

With north to northeast flow, temperatures should be limited to
the 50s in many areas.

Some rain will likely linger into the evening across the
southern half of the area as the low moves off the north
carolina coast. As cold advection continues behind the low,
there could be a brief changeover to snow, mainly at elevations
above 2500 feet or so. Otherwise precipitation should exit
before temperatures fall to near or below freezing late at
night.

A vast area of canadian high pressure will slide southeast
toward the area Tuesday, allowing for clearing skies and a
chilly north breeze. The cold advection will limit high
temperatures to the 40s, with subfreezing low temperatures
expected in most areas Tuesday night.

Long term Wednesday through Saturday
The latter half of the upcoming week and into the first half of next
weekend will feature dry and warming conditions as heights build
across the region.

Surface high pressure will be located along the eastern seaboard on
Wednesday before sliding offshore Thursday. Heights aloft will build
during this time as well as the pattern amplifies ahead of a
developing low pressure system across the central us.

The high will remain positioned offshore of the eastern us through
Friday and Saturday as the low pressure system ejects northeastward
from the central plains and into the great lakes. Heights aloft will
then begin to fall during the day Saturday.

All of this spells out dry weather through the period with
temperatures ticking up each day as southerly flow becomes more
pronounced and heights temperatures increase aloft.

Highs in the 50s Wednesday will warm to near 60f Thursday, in the
60s to near 70f Friday, and likely in the 70s on Saturday. Lows
midweek will be in the 20s 30s, moderating to the 40s by the
weekend.

Aviation 07z Sunday through Thursday
High pressure will move off to the east today. Mid and high
level clouds will increase with south winds increasing to around
10 kt this afternoon.

Clouds thicken and lower tonight into Monday morning ahead of an
approaching low pressure system. While there could be some light
rain late tonight into Monday morning, low levels will be dry,
so would expectVFR conditions to continue. The best chance at
MVFR conditions will come Monday afternoon into early evening as
a shield of rain moves across the area. Ifr is not out of the
question, but it's the lower probability outcome at this time.

Vfr should return Monday night and continue through Tuesday with
northerly winds developing.

Vfr under high pressure Wednesday and Thursday.

Marine
Light and variable winds this morning will become southerly
today as high pressure moves off the coast. The pressure
gradient will increase, though am not confident mixing will be
efficient enough for winds much above 15 kt. Thus will hold off
on an advisory for now. Southwest flow may stay elevated through
this evening, but will then become lighter late tonight into
Monday morning as a wave of low pressure passes south of the
area. As this low passes off the north carolina coast Monday
evening, there will be a better chance of small craft advisory
conditions in northeast to north flow. These gusty winds will
likely persist into Tuesday as strong high pressure builds in
from the northwest.

Sub-sca conditions Wednesday and Thursday with high pressure in
place.

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.
