Synopsis
A warm front will slowly lift north across the region today. A
strong cold front will then cross the region late Wednesday. A
wave of low pressure may pass southeast of the region Thursday
into Thursday night. Another, weaker cold front may cross the
region over the weekend.

Near term through Wednesday
Warm front is slowly pushing north of the region at present,
though warm advection is producing plenty of showers and
drizzle. As the front continues to lift northward through the
day, expect temperatures to gradually continue warming, with
showers, drizzle and fog slowly dwindling from southeast to
northwest. By late afternoon, most areas should be well into the
70s or low 80s. The warmth and humidity may produce a stray
thunderstorm this afternoon, but coverage should be small.

Tonight a lull in precip will envelop the area as we sit in the
warm sector. This will likely promote some patchy fog given the
high moisture and light winds, though cloud cover will mitigate
this somewhat. Lows will remain mild, with 60s and perhaps some
low 70s.

Strong cold front will then approach from the northwest on
Wednesday. The morning should be fairly quiet, but by afternoon,
thunderstorms will start developing to the northwest and then
cross the region from northwest to southeast. With highs
expected to reach the 80s with high dew points, CAPE should
approach 2000 j kg, possibly exceeding 2000, and shear will be
in the 20-30 knot range, possibly exceeding 30 knots late, so
some severe thunderstorms look probable. SPC has placed much of
the region from i-95 north adnd west in a sligh risk.

Short term Wednesday night through Thursday night
Strong cold front will cross the region most likely during the
evening Wednesday, though there remain some timing differences
among the guidance. Thunderstorms will progress southeastward,
likely clearing the region. However, the front looks to stall,
and guidance is hinting at a wave of low pressure developing and
moving northeast along the stalled front later Thursday into
Thursday night. Thus, the chance of showers will linger even as
cooler air builds southward behind the front. Lows Wednesday
night and highs on Thursday will be considerably cooler, with
few places staying in the 60s at night, and many locales failing
to reach 70 on Thursday.

Long term Friday through Monday
A dry frontal passage is expected Sat afternoon that will bring
slightly cooler air for Sun and mon. Upper level flow is then
expected to become largely zonal early next week, while at the
surface, weak high pressure will settle northeast of the area
keeping generally fair weather conditions and seasonable
temperatures.

Aviation 08z Tuesday through Saturday
Warm front slowly lifting north across the region has produced
low CIGS and vis in drizzle and showers. This will gradually
wane through the day as the front lifts north, though a shower
or thunderstorm will remain possible at all terminals this
afternoon. Last place to break into the warm sector will likely
be mrb. Patchy fog will be a concern again tonight, but
otherwise it should dry out. Wednesday will start dry, but gusty
thunderstorms are possible in the afternoon, which may linger
into the evening. Showers may then linger at times through
Thursday night, with associated reductions in cig vis possible.

A dry frontal passage is expected Saturday with shifting winds.

Marine
Diminishing winds this morning as the warm front lifts
northward, so may be able to cut some of the SCA out. That said,
southerly flow may continue to produce gusts over the bay much
of the day. Winds will stay gusty as a cold front crosses the
area later Wednesday, and special marine warnings may also be
necessary due to strong thunderstorms. Winds turn north and
gusty behind the front Thursday, with lingering showers.

Winds will remain below SCA and generally below 10 kt Friday
through Sunday.

Tides coastal flooding
Water levels are expected to continue to slowly rise through
tonight and then begin to slowly recede Wed before dropping more
sharply Wed night as cold front pushes south as winds shift to
the nnw. Expect the next two high tide cycles to see minor to
moderate coastal flooding along the potomac river and chesapeake
bay. Minor coastal flooding could persist into Wed before water
levels drop more rapidly Wed night. Have extended advisories
and warnings through tonight as confidence is high on
experiencing coastal flooding.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
