Synopsis
A weak frontal boundary will remain south of the area overnight
into Wednesday, as high pressure slides off the northeast
coast. The next low pressure system affects the region late
Thursday through at least Friday night.

Near term until 6 am Wednesday morning
Late this evening, a frontal boundary was well south of the
region over the carolinas, and high pressure was cntrd over wrn
ny. The cntr of the high will slide ewrd and should maintain dry
wx and more comfortable temps overnight. The NE sfc flow will
bring some more clouds down into NE counties, but otherwise,
expect a clear to partly cloudy sky. Lows will range fm the mid
60s to near 70.

Short term 6 am Wednesday morning through Friday
Dry wx continues for the beginning of the short term period with
the aforementioned sfc high sliding off the NE coast and
onshore flow continuing with the front weakening south of the
area. There is a very small chance of a shra over eastern areas,
but the chance is not high enough to include mention in the
forecast ATTM so will re-evaluate with future updates. Another
day of below normal temps with highs only in the low mid 80s.

Attention then turns Thu to an approaching potent mid-level
shortwave trough and associated sfc low. Expect dry wx thu
morning, with pops increasing later in the day to 30-40%
along west of i95 late aftn early eveng in association with a
lead shortwave aloft and sfc prefrontal trough. Chances of rain
then further increase into Thu night to chance-likely pops
everywhere as the main sfc low cold front approach the mid atlc.

Spc has included the entire fa in a slight risk for severe
storms, with the main threat being damaging wind gusts. This
threat may continue into Thu night, and potentially Fri with the
area still in the warm sector, and strong deep layer shear and
shortwave energy aloft for late july. Heavy rain is also psbl
with the strong forcing and high pwat. Will include mention in
the hwo. Bumped up pops to 60% everywhere fri.

Long term Friday night through Tuesday
Potent shortwave progged to dig into the mid-atlantic region Friday
night into Saturday, before de-amplifying and pushing offshore
Saturday. An associated cold front pushes offshore Saturday morning.

Have kept high end chance pops central virginia eastward Friday
night as the front pushes across the region. Low pressure forecast
to develop along the frontal boundary as the strongest height falls
spread across the region. The low lifts along the northeast coast
Saturday as the front stalls along the southeast coast. Lingering
mid-level moisture and the shortwave pushing across the region will
keep slight chance to chance pops Saturday afternoon. Cooler behind
the front, with highs generally in the mid 80's. An upper level
trough remains over the eastern us through early next week, as a
ridge of high pressure remains entrenched over the western atlantic.

High pressure slowly builds in from the midwest Sunday and Monday as
the front stalls along the southeast coast. The GFS keeps the
moisture farther offshore, but the ECMWF hugs the coast, developing
a wave of low pressure off the carolina coast. Have kept slight
chance to low end chance pops across the far southeast forecast area
Sunday and Monday. Highs Sunday and Monday generally in the mid
80's. Medium range guidance indicates the subtropical high over the
western atlantic may retrograde slightly Tuesday, which could push
the coastal front inland. Have introduced low end pops Tuesday as a
result. Warmer, with highs in the mid to upper 80's, but still
relatively comfortable this time of year with dewpoints in the low
to mid 60's.

Aviation 02z Wednesday through Sunday
Vfr conditions through the TAF period. Sky should be generally
clear or with a few scattered clouds tonight. Winds will be
ne E overnight and wed. Some patchy fog may occur on the
eastern shore tonight but there is no confidence whether sby
will be adversely affected.

Outlook: primarilyVFR conditions expected through thu. A cold
front approaches the area late Thursday into Friday bringing the
threat for showers and thunderstorms. Showers and thunderstorms
may linger into Saturday, but drier conditions arrive for the
second half of the weekend.

Marine
Latest surface analysis places a cold front south of the local
waters with high pressure over the great lakes. A weak area of low
pressure is centered just offshore the mid-atlantic coast. Obs
indicate a north to northeast wind of 10 to 15 knots. Seas generally
2-3 feet and waves 1-2 feet. Gradient winds diminish tonight as low
pressure pushes away from the coast and high pressure builds across
the northeast, but some modest cold advection will keep speeds
around 10-15 knots. An onshore flow of 10-15 knots Wednesday will
push seas to 3-4 feet. Waves generally 2 feet. High pressure slides
offshore Wednesday night ahead of an approaching cold front. Flow
becomes southerly, and increases to 10-20 knots Thursday afternoon
as the gradient strengthens. Marginal SCA conditions are possible.

The front stalls near the coast Thursday night into Friday, before
an upper level disturbance pushes the front offshore Friday night.

Expect a west to southwest wind Friday at 10-15 knots, with marginal
sca conditions possible ahead of the front Friday evening. Flow
becomes north to northwest 10-20 knots behind the front Friday
night. Strong cold advection and strong pressure rises expected late
Saturday and Saturday night as low pressure deepens along the mid-
atlantic and northeast coast. The result will be solid sca
conditions over the waters, with the potential for low end gale
conditions over the upper bay and northern coastal waters. The front
stalls along the southeast coast through early next week as high
pressure slowly builds in from the west. A north to northeast wind
at or below 15 knots is expected through early next week.
