Synopsis
A surface boundary associated with the remnants of florence
will move through our area today. High pressure will build over
the region Wednesday into Thursday before residing over the
western atlantic late in the week. A cold front will approach
from the northwest toward the end of the week before stalling
over the region through the weekend.

Near term through tonight
Winds have shifted out of the northwest for much of the region
this afternoon, with the exception being southern maryland where
winds remain south southwesterly. This wind shift signifies a
frontal boundary associated with the remnants of florence,
currently over southern new england, is moving through the area.

Along the boundary is a broken line of showers and isolated
thunderstorms, and with the drier northwest winds quickly on its
heels, this line of activity has really lacked any vigor.

Additionally, because of its progressive nature, this allowed an
early cancellation of the flash flood watch that was in effect
for portions of the metro areas. Brief pockets of heavy rain and
a few lightning strikes will still be possible across the
bay tidal potomac waters and over southern maryland for the
remainder of this afternoon.

Behind this boundary, decreasing clouds and breezy northwest
winds will usher in a less humid airmass. A few light showers
cannot be ruled out, but in general a drying trend is expected
through the overnight period as high pressure builds in from the
west. Temperatures tonight will settle in to the 60s for much of
the region.

Short term Wednesday through Thursday night
High pressure at the surface and aloft will dominate over the
region the next several days. This will deliver dry conditions,
mostly clear skies, and a more comfortable airmass with
dewpoints in the low to middle 60s. Temperatures will hover near
or slightly above normal Wednesday through Thursday night.

Long term Friday through Monday
As the high moves offshore Friday, a cold front will sag southeast
across the eastern great lakes and move close to our northwestern
zones of western maryland and eastern west virginia by Friday night.

Dry conditions will continue Friday with a chance of a few showers
in our northwestern zones Friday night. Temperatures will be warmer
Friday.

A cold front will slide southeast across our region Saturday into
Saturday night, bringing an increased chance for showers and
thunderstorms across much of our region. At this time, it appears
that most activity will be isolated since much of the upper level
support will have left the region and moved well to the northeast.

The front could stall across southern parts of our region or perhaps
reach the virginia and north carolina border Sunday and Sunday
night. Additional showers or perhaps a thunderstorm could form along
and just north of the front. Slightly cooler temperatures near the
mason-dixon region.

Weak high pressure will try to nudge farther south into our cwa
Monday, but it may have trouble with its push since the stalled
front could hold its ground in southern parts of virginia.

By Tuesday, high pressure will move off to the northeast. A return
flow will usher in more warmth and higher humidity. A cold front is
expected to push across the eastern great lakes Tuesday and move
into our region Tuesday night.

Aviation 19z Tuesday through Sunday
The frontal boundary and associated showers and isolated
thunderstorms have pressed east of the terminals this afternoon.

A light passing shower cannot be ruled out, but generally drier
conditions and breezy northwest winds can be expected the
remainder of the day. Thus predominateVFR conditions are
forecast. Patchy fog is a possibility overnight at mrb cho, but
given the drier air filtering in to the area, have left out of
the forecast at this time.

Vfr conditions will persist wed-thu as high pressure builds
over the region, delivering clear skies and no threat of
precipitation. Northerly breezes at 10-15 knots Wednesday will
slacken and remain at less than 10 knots Wednesday night
through Thursday night.

Vfr conditions expected Friday and Friday night. A cold front will
push into parts of our region Saturday and Saturday night that could
bring a few showers or a storm. Winds southwest around 10 knots
Friday and Friday night. Winds southwest becoming north around 10
knots.

Marine
A frontal boundary is crossing the waters this afternoon. A
broken line of light showers and isolated thunderstorms have
resulted, which could bring locally gusty winds with any
stronger activity. Gusty northwesterly winds will prevail behind
the boundary, and continue into Wednesday morning, thus a sca
remains in effect. Winds will abate Wednesday afternoon evening
as high pressure settles over the waters, persisting through
Thursday night. This will bring a return to sub SCA conditions.

No marine hazards expected Friday through Saturday night. Winds
southwest 10 to 15 knots Friday and Friday night. Winds becoming
northerly at 10 to 15 knots Saturday and Saturday night.

Hydrology
River flooding is ongoing along some of our river basins.

Please refer to the latest river flood watches and warnings for
additional information.

Tides coastal flooding
Northwesterly flow in the wake of a frontal passage will
promote falling tidal anomalies through tonight, thus coastal
flooding is not anticipated the next several days.
