Synopsis
High pressure will build from the tennessee valley toward the
region through the end of the week. A cold front may approach
from pennsylvania this weekend.

Near term through 6 am Wednesday morning most locations
have reached the 70s as temperatures continue to drop this
evening. A ridge of high pressure will keep us dry and quiet the
rest of the night with dewpoint temperatures lowering into the
upper 50s to lower 60s.

Short term Wednesday through Thursday night
A large high pressure ridge will provide quiet and seasonably
warm conditions Wednesday. A westerly flow Wednesday will keep
dewpoints from rising. Heat indices will be close to actual
temperatures during the day. Any chance of showers or
thunderstorms would be mainly along the maryland border.

Wednesday night will be quiet. Any showers or thunderstorms
along the maryland border early will dissipate with loss of
daytime heating and sunset.

By Thursday, flow backs slightly to the southwest, so the
humidity may rise slightly by then.

Subsidence should mostly inhibit convection Thursday too.

The forecast will remain dry.

Long term Friday through Tuesday
Mid-upper level ridge will be at its maximum amplitude over our cwa
thu and Fri with continued hot and dry conditions. Hottest
temperatures are expected Fri and possibly into Sat too. Digging
upper level closed low from james bay into northern new england
Sunday will help push a weak cold front through the area Sunday and
bring a slight reprieve to the hot weather (highs around 90 as
opposed to mid 90s) along with a chance of showers and thunderstorms
mainly to northern areas Sat afternoon and Sunday. Saturday could
turn out to be the hottest day just ahead of the frontal passage and
also when humidity is expected to be highest. It could be close to
heat advisory criteria in some areas Sat especially in the south.

Ridge tries to build from the west toward the middle of next week
with temperatures climbing back well into the 90s.

Aviation 02z Wednesday through Sunday
Vfr conditions will prevail through the valid TAF period.

Dewpoints will be low enough to preclude significant fog
development.

Hot temperatures will be the main concern for the rest of the
week. Risk of t-storms Sat and sun.

Marine
Light winds then gradually back southwest by Thursday. Local
onshore bay breeze effects expected each afternoon. Winds
anticipated to remain below small craft advisory thresholds
through the end of the week. Risk of thunderstorms Sat and sun
with a frontal passage.

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.
