Synopsis
A cold front will approach from the north through this evening
before passing through overnight into early Friday. High
pressure will briefly build overhead later Friday through Friday
night before moving offshore Saturday. A weak cold front will
stall out nearby for Sunday and Monday, and a bermuda high may
cause hot and humid conditions during the middle portion of next
week.

Near term through tonight
A severe thunderstorm watch is in effect until 8 pm this evening
for much of northern virginia, central and southern maryland,
and eastern west virginia.

A south to southwest flow has caused a return of noticeably
warmer and more humid conditions this afternoon. Latest
mesoanalysis shows around 1000-2000 j kg of MLCAPE developing
ahead of a line of showers and thunderstorms. The line of
showers and thunderstorms is expected to pass through the
washington and baltimore metropolitan areas between 3 and 5 pm
this afternoon, and then across southern maryland into central
virginia later this afternoon into early this evening. Deep
layer shear remains quite strong (around 45-50 knots ahead of
the line). The combination of the instability and strong shear
suggests that severe thunderstorms are possible with damaging
winds and large hail being the primary threats. The best chance
for severe storms are most likely near and east of the blue
ridge mountains across northern virginia into the virginia
piedmont as well as the washington and baltimore metropolitan
areas southern maryland. These areas are east of a pressure
trough, and somewhat higher dewpoints has allowed for the higher
instability. An isolated tornado cannot be ruled out due to the
strong shear as well.

The cold front will drop into the area from the north this
evening before slowly moving through our area into central
virginia overnight. Scattered showers and thunderstorms may
accompany the frontal passage later this evening, and with
strong shear in place there is a threat for severe
thunderstorms. However, confidence is lower due to the loss of
daytime heating. Convection should dissipate overnight as the
front drops farther south and drier air begins to filter in from
the northwest.

Short term Friday through Saturday night
The cold front will continue to drop south Friday and weak high
pressure will build overhead later Friday into Friday night.

Warm conditions will continue, but it will turn out breezy and
noticeably less humid behind the boundary.

High pressure will move offshore Saturday and a return southerly
flow will usher in a return of more humid conditions. A few
showers and thunderstorms are possible in the afternoon and
evening, especially west of the blue ridge mountains where
instability will be higher and there will be a pressure trough
that acts as of lifting mechanism.

Warm and humid conditions are expected Saturday night due to a
southwest flow around high pressure offshore.

Long term Sunday through Thursday
Sunday will be a very warm and potentially unstable day, with a
cold front dropping toward the region. Timing will be key, as
there is the potential for another active afternoon evening if
the front drops south of the md pa border overlapping with any
daytime heating.

Present indications suggest that the boundary could sag south of
the area Monday, but the ridge will intensify Tuesday-
Wednesday. If that holds true, the middle of next week will be
very warm if not hot. However, anticipate model fluctuations on
these details. This would also impact thunderstorm chances,
which at this point don't look very high.

Aviation 18z Thursday through Tuesday
A line of showers and thunderstorms will likely pass through the
terminals this afternoon, between 19 and 21z. The best chance
for thunderstorms will be across kiad, kbwi, kmtn, and kdca.

Locally damaging wind gusts and large hail are possible.

A cold front will pass through the terminals tonight. Another
round of scattered showers and thunderstorms are possible late
this evening, but confidence is lower due to the loss of daytime
heating.VFR conditions are expected most of the time Friday
through Saturday. Northwest winds will gust around 20 knots
Friday before diminishing Friday evening. Winds will turn to
the south for Saturday.

The only apparent flight restrictions at this time would be within
showers thunderstorms. Sunday afternoon-evening seems to be the
best opportunity.

Marine
A line of showers and thunderstorms will likely pass through the
waters late this afternoon into early this evening. Damaging
winds and large hail are possible, and a waterspout cannot be
ruled out. Storms are most likely to pass through between 4 pm
and 7 pm this afternoon and early evening.

Another round of showers and gusty thunderstorms are possible
later this evening, but confidence is lower due to the loss of
daytime heating.

A small craft advisory is in effect for the waters until
midnight. There may be a brief lull in the stronger gradient
winds overnight before winds increase behind a cold front
Friday. A small craft advisory is in effect for the waters
Friday into Friday evening. High pressure will briefly build
overhead Friday night before moving offshore Saturday.

Thunderstorms may be affecting the waters late Sunday, with
northwest flow conducive for small craft advisories behind the
front, lingering into Monday.

Tides coastal flooding
Elevated water levels are expected through this evening due to a
southerly flow, but confidence is too low for an advisory due to
a westerly component to the wind and the fact that the next high
tide will be the lower of the two this evening.

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.
