.SYNOPSIS...
High pressure builds in north of the region through Sunday as an
areas of low pressure moves eastward across Virginia and the
Delmarva Sunday night through Monday morning. A cold front passes
across the region Tuesday through Tuesday night. Much warmer and
drier weather dominated by high pressure will settle over the area
Wednesday through Friday. A cold front may approach the area from
the north by early next weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
A cold front has stalled out just to our south across
southern Delmarva early this morning. Meanwhile a new area of
low pressure is taking shape across the midwestern states while
to our north, high pressure is centered over Quebec. As we get
into Sunday our area will be north of the front in a stable
easterly flow between the high to our north and the low to our
south as it pushes eastward toward Virginia. 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. Expect highs Sunday generally in the low to mid 70s
under a mainly cloudy sky.

Showers and isolated thunderstorms will gradually taper off with
time by later Sunday evening into the overnight as surface ridging
builds in from the north and east. It will remain mostly cloudy with
a continuing east to northeast flow and lows mainly in the upper 50s
to low 60s. The cloud deck will be quite low with the continuing
marine influence and there could also be some patchy fog and
drizzle around.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY/...
Little change is expected as we head into the day Monday. The SW
extent of surface ridging emanating from an area of high
pressure that will be centered over the Canadian Maritimes by
this time will remain over the area with a continuing onshore
flow and associated marine stratus deck. This will keep it
mostly cloudy with highs once again in the low to mid 70s. While
no significant rainfall is expected there may continue to be
some spotty light showers and patchy drizzle around.

The weather gets a bit more active again Monday night into
Tuesday as a cold front approaches from the west Monday night
and moves through the area on Tuesday. This will bring another
round of showers and storms through the area...especially
overnight Monday night into the first part of Tuesday. This all
said, the instability will be low, which should limit the threat
for severe thunderstorms and heavy downpours. QPF amounts
during this period should generally range from one quarter to
three quarters of an inch. Lows Monday night should generally be
in the upper 50s to low 60s with highs Tuesday generally
ranging from the mid 70s to low 80s. Tuesday night should see
similar if not slightly cooler overnight lows compared to Monday
night as skies start to clear out.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
High pressure builds in for wednesday and Thursday bringing sunshine
with dry weather and another warming trend. Highs Wednesday look to
be mainly in the low to mid 80s with highs by Thursday reaching the
upper 80s to near 90 for many areas. Humidity levels will be low
Wednesday before starting to creep up a bit on Thursday.

As we get towards the very end of the week into next weekend,
another cold front will start to push southward towards the area
bringing a return to chances of showers and thunderstorms. At this
point the best chance of precipitation looks to be Saturday as there
may be an area of low pressure that develops along the front as it
may tend to stall near the area. Friday looks to be another day with
highs well into the 80s to around 90 with temperatures starting to
cool for Saturday.

Sub Small Craft Advisory conditions continue through Monday. Winds
become northeast around 10-15 knots for Sunday and then diminish
slightly for Sunday night and Monday. Generally expect seas around 3
to 4 feet through this period.

Outlook...

Generally expect sub Small Craft Advisory conditions to continue
through most of this period except late Tuesday into Tuesday night
seas may approach 5 feet. Also expect some showers and isolated
thunderstorms over the waters on Tuesday.

Rip Currents...

For Sunday, winds will be from the E/NE around 10 mph with a medium
period swell of around 7 seconds and wave heights in the surf zone
around 2 to 3 feet. There will also be some longer period wave
groups as well. For these reasons, a MODERATE risk of rip currents
will continue. Little overall change will occur into Monday except
we`ll be within two days of the June 11 Full Moon. For these reasons
a MODERATE risk of rip currents looks to continue.
