Synopsis
High pressure will build tonight through Wednesday. Low
pressure will move northward along the atlantic coast Wednesday
night. A cold front will pass through the area Thursday and high
pressure will return for Friday into the weekend.

Near term through Tuesday
Latest surface analysis shows high pressure centered over the
ohio valley, with low pressure well to our south over the
western atlantic. Aloft, a shortwave is crossing the region at
present.

The high pressure will move directly across the region during
the rest of tonight into Tuesday as the upper level trough
slowly lifts out, resulting in dry weather with clearing skies.

The chilly canadian air mass and light winds will allow temps
to drop below freezing in most surburbs, and possibly even in
the urban areas and along the tidal waters. Chilly conditions
will continue Tuesday despite sunshine, with highs struggling to
reach the 50s. This will be a few degrees below normal for this
time of year, though the deviation isn't all that great.

Short term Tuesday night through Thursday
High pressure shifts eastward into the atlantic Tuesday night
and Wednesday but will remain in overall control. Temperatures
should moderate a bit but we're not expecting a big warm up from
Tuesday to Wednesday... Just closer to normal, really. Skies
will generally remain clear to partly cloudy.

Things get more interesting Wednesday night as a trough digging
to the west induces cyclogenesis along the carolina coast, which
then rockets northeastward. This trough looks pretty potent,
with some phasing potential, but the question for our region is
just how far west will the low pressure's influence make it.

Latest guidance has trended westward with the low track and the
precip, so have generally increased pops across our region,
especially eastern areas, for Wednesday night into Thursday. It
must be noted that temps may remain a bit marginal Wednesday
night, and a few models with the more westerly track are hinting
that a little snow may mix with the rain north and west of the
i-95 corridor. For now have confined snow to the high mountains,
but this will need to be watched closely if the trend
continues.

The coastal low rockets northeastward during the day Thursday,
but a cold front will be approaching from the northwest. This
means there may not be much of a gap between the rain with the
coastal low (should that rain make it into our region) and
showers associated with the cold front. However, southerly flow
ahead of the front, plus insolation, should allow temps to rise
noticeably, resulting in mostly rain showers during daylight
hours.

Long term Thursday night through Monday
On Thursday night a cold front cross the region. Behind the
frontal passage, high pressure will build into our region from
the upper midwest and linger through Sunday. A few upslope
showers Friday morning can't be ruled out in eastern west
virginia and western maryland. Winds will become northwest to
westerly leading to temperatures remaining mild for this time of
the year. By the end of this weekend, temperatures are expected
to trend back upwards as high as the 70 degree mark.

Aviation 01z Tuesday through Saturday
Vfr conditions prevail thru Wednesday as high pressure crosses
the region. Winds generally below 15 knots.

Coastal low pressure moving up the coast may spread rain and
sub-vfr conditions westward into the eastern terminals Wednesday
night into early Thursday. Then, a cold front will cross the
region later Thursday Thursday evening, with potential for more
brief sub-vfr conditions in showers.

High pressure will build into our region on Friday with
winds mainly out of the west. Clouds will slowly dissipate on
Friday with some higher clouds lingering over our region.VFR
conditions expected at this time.

Marine
Sub-sca conditions expected through Wednesday. Wednesday night
into early Thursday, a coastal low pressure moving northward up
the coast may bring SCA winds to the waters. Later Thursday into
Thursday night, a cold front may do likewise.

Friday, winds will become westerly ith strong winds aloft
hovering near or above 18 knots which suggests small craft
advisories may be needed.

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.
