Synopsis
High pressure will build west of the area through Tuesday. A
cold front will cross the region Tuesday. High pressure will
move over the region Wednesday and settle offshore late in the
week.

Near term today
As of 3am, an upper trough stretches from the canadian prairies to
the midwest then up over new england per water vapor imagery. A
1024mb surface high is centered over kansas city. This surface high
will drift east to the central mid-atlantic through Tuesday night
before the center moves off the mouth of the chesapeake bay
Wednesday. West flow and cold air advection under the upper trough
will keep temperatures below normal through Wednesday night.

A weak shortwave trough rounds the upper trough and crosses the mid-
atlantic tonight. The airmass should be too dry for any shower
development. However, the low 80s surface water temps of the
chesapeake will continue to be a notable moisture source. A shower
cannot be ruled out near the bay this afternoon.

Short term tonight through Wednesday night
The upper trough axis crosses the area Tuesday night. This should
provide enough forcing for widely scattered showers with isolated
afternoon thunderstorms. Otherwise, expect the coolest day in three
weeks with MAX temps in the upper 70s.

Return southerly flow that begins late Wednesday behind the surface
high.

Long term Thursday through Sunday
After a cool (for late june) period high pressure moves offshore
Thursday and the heat and humidity return through the weekend.

Still, not extreme heat: upper 80s around 90.

It is hard to pin down the exact timing chance of precipitation
several days in advance, but for now it looks like Saturday
night Sunday would have the best chances as a shortwave tracks
north of the forecast area.

4th of july is still beyond the scope of this forecast, but for
now neither the GFS or euro shows anything too dangerous -
euro's upper pattern is high zonal while GFS has a weak upper
trough running down the eastern seaboard.

Aviation 07z Monday through Friday
Vfr prevails through the week as high pressure slowly builds from
the west. Passing shower isolated thunderstorm Tuesday ahead of a
cold front.

Vfr conditions expected Thursday and Friday.

Marine
Nwly flow may gust to around 20 knots this morning, but confidence
is low, so winds were capped at 15 knots. High pressure slowly
builds through Wednesday. Return southerly flow begins Wednesday
night as the high shifts to bermuda.

Winds expected to remain below SCA values Thursday Friday.

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.
