Synopsis
High pressure will slide southward tonight and then offshore through
the weekend. A cold front will approach from the west on Monday,
crossing the area Monday night. High pressure will return for the
midweek period.

Near term until 6 am Saturday morning
Another quiet night ahead tonight as high pressure remains to our
south an a surface trough remains in place. Even with a couple of
weak short wave vorticity impulses overnight, only periodic cloud
cover is expected as there is limited moisture. As winds go light
and temperatures cool, some patchy fog is again possible.

Short term 6 am Saturday morning through Sunday
Dry weather will continue through Saturday and Saturday night as
high pressure remains to our south and a surface trough remains
across the area. Temperatures will warm well above normal starting
Saturday as ridging aloft builds across the east coast and return
flow brings in warmer, more moist air. Vertical moisture remains
limited, so precipitation is not expected through Saturday night,
regardless of any short wave vorticity impulses.

By Sunday, the ridge aloft breaks down while the high pushes
offshore of the mid-atlantic coast and the weak surface trough
remains near the area. This will allow for the return flow to
continue through Sunday. Very warm temperatures and increasing
moisture are expected through Sunday. Later Sunday, there is a
chance some showers may develop to our west, but they are expected
to stay out of our area and remain near the surface trough as it
drifts westward through the day.

Long term Sunday night through Friday
Not much change in the extended period as we are largely dominated
by high pressure. Main opportunity for precipitation will be with
the frontal passage on Monday night.

A cold front will approach the region from the west on Monday,
crossing through the area Monday night. Low level moisture will be
on the rise in the return flow around the departing high pressure.

Flow looks to be pretty progressive with the front working through
the area Monday night and then offshore by Tuesday morning. Some
instability may develop head of the front with the best forcing
right in front of and along the boundary. Only will mention a slight
chance of thunder, mainly during the afternoon, with it waning once
we head into the evening and lose the diurnal component.

Once the front moves through, high pressure starts to build back
into the region. There may be a weak front that moves through on
Thursday but most guidance shows little moisture around and it may
not be much more than a wind shift across our area.

Aviation 20z Friday through Wednesday

Marine
Tonight... Small craft advisory continues on the atlantic ocean
coastal waters through tonight with seas around 5-6 feet.

Saturday... The small craft advisory will continue into the first
half of the day, before dropping during the afternoon as seas
subside.

Saturday night... Conditions expected to remain below advisory levels
overnight.

Sunday... Winds increase through the day Sunday and may reach
advisory levels by late afternoon.

Sunday night through Monday night... Seas may start to build to
around 5 feet Sunday night, continuing through Monday night. A small
craft advisory will likely be needed for the ocean waters.

Tuesday through Wednesday... Seas subside into Tuesday morning,
falling below advisory levels and remaining sub-advisory through
Wednesday.

Rip currents...

a high risk for the development of dangerous rip
currents continues through today as the long period swells and high
seas continue from hurricane humberto. A rip current statement
(under the coastal hazard message) is carrying the related info.

The risk for Saturday will be at least moderate, but may possibly be
high like Friday.
