.SYNOPSIS...
A cold front will move southward across the region from north to
south early tonight. High pressure builds in from the north
later tonight, then lifts north of the area Sunday as another
area of low pressure moves eastward across Virginia and the
Delmarva Sunday night through Monday morning. Another cold
front passes through the region Tuesday through Tuesday night.
Much warmer and drier weather will settle over the area
Wednesday through Friday with afternoon temperatures in the 80s
to around 90 degrees.

&&

.NEAR TERM /THROUGH SUNDAY/...
A surface cold front from the Poconos to southwestern
Pennsylvania early this afternoon will slowly track eastward the
rest of the day passing south of Delmarva by 03Z Sunday. An
area of rain and isolated thunderstorms ahead of the front will
move offshore by 19Z today. The front will also have a thin
band of convection with its passage.

Any convection tapers off this evening. Another warm and muggy
night on tap with fog and stratus develops in a northeast to
east flow.

On Sunday our area will be north of the front in a stable
easterly flow between high pressure over New England and low
pressure moving eastward across Virginia and lower Delmarva.
Showers and isolated thunderstorms will develop to the north of
the front by late morning and continue throughout much of the
afternoon. Deeper surface-based convection will remain south of
the front, which at this time should stay well south and west
of our region.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/...
Showers and isolated thunderstorms taper off Sunday night, and
then high pressure noses in from the north.

Conditions should be dry most of the day Monday, but another
upper trough with a strong surface cold front moves through the
Great Lakes and into the Ohio Valley during the day. Some
shortwave energy spinning off ahead of that trough may trigger
some afternoon and evening showers and thunderstorms, but the
bulk of the activity holds off until late Monday night as that
front gets closer, and activity will mainly be focused on the
far western areas.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
Another active weather day on tap for Tuesday with showers
likely with a chance for thunderstorms as low pressure develops
on that front and moves through the region during the day. The
front crosses the region Tuesday night, and then high pressure
builds in from the north and west.

Dry weather on tap for Wednesday and Thursday with highs
climbing through the 80s. Friday should be dry, but another
frontal boundary will gear up to make a run at the area. Highs
may approach 90 on Friday.

.MARINE...
A Small Craft Advisory is in effect through 6PM for the ocean
waters as seas will be around 5 ft. Winds will be out of the
south to southwest at around 10 kt. Winds turn NE around 10 kt
tonight with 3 to 4 ft seas. East winds around 10 knots on
Sunday and seas 3 to 4 ft.

Outlook...

Sunday night through Tuesday...Sub-SCA conditions. VSBY
restrictions and locally higher winds and waves in showers and
isolated thunderstorms Sunday night, then again on Tuesday.

Rip Currents...

For Saturday, the onshore swell increases to 3-5 feet with a medium
7-9 second period. Additionally, some longer period waves may be
embedded in the swell. Breaking waves in the surf zone of 2-3 feet
are expected as a result. Winds will be around 5-10 mph out of the
southwest to west-southwest. Due to the increasing and potentially
multi-period swells, there is a MODERATE risk for the development of
dangerous and life threatening rip currents for all beaches on
Saturday.

For Sunday, the wave heights will diminish slightly but the flow
will turn more onshore. There will continue to be a medium period
swell around 7 to 9 seconds with some longer period wave groups as
well continuing. For these reasons, a MODERATE risk of rip currents
will continue.
