Synopsis
High pressure remains over the mid atlantic region through
the weekend... With temperatures gradually warming. The next
cold front is expected to impact the region Monday night and
Tuesday.

Near term until 6 pm this evening
Sfc hi pres sfc-aloft remains anchored INVOF fa through today.

Other than patchy areas of fg... ESP in interior SE va-ne
nc... Dry-continued skc and seasonably warm wx expected again
today. Winds remaining vrb mainly AOB 5 kt. Highs 75-80f... L70s
right at the coast.

Short term 6 pm this evening through Monday
High pressure slowly shifts off the coast tonight-sun.

Potentially a little better coverage of patchy areas of fg by
late tonight due to light ese winds. Otherwise... Dry-continued
seasonably warm wx. A few more clouds possible by Sun afternoon
due to the low level flow from the SE ahead of the next cold
front (which will be entering the oh-tn valleys late) - so may
become partly sunny vs mostly sunny. Lows tonight in the u40s-l50s
inland to the m-u50s at the coast. Highs Sun ranging through
the 70s.

By mon... Low pres deepens over the deep south lower ms valley
while a strong upper ridge remains in place along just off the
east coast. 00z 21 GFS and ECMWF showing only very subtle timing
differences with respect to how quickly the precip from the
southern low is able to spread east into the mid-atlantic.

Based on 00z 21 suite of models... Keeping pops AOB 20%
throughout the local area. While pops tend to increase late in
the day w... May also be tad higher area of pops near the coast
in SE va-ne nc toward Mon eve. Otherwise... Clouds will be on the
increase (gradually) from w-e mon. Highs again in the m-u70s
(l70s right at the coast)... After morning lows in the 50s-around
60f.

Long term Monday night through Friday
Still a lot of uncertainty as to how next weeks system plays out as
models offer up different timing and moisture field solutions. What
is agreed upon is that a full latitude trof will move across the
region tue, what is yet to be determined is the scope and track of
several S w's embedded in the trof and timing of a cold frontal
passage across the area. GFS slower much wetter as copious amounts
of gom moisture gets transported north ahead of the front. Ecmwf
faster drier with the FROPA with a dry slot cutting the pcpn off.

Decent low level jet and theta-e advection progged ahead of the
front for at least some instability to develop. Went ahead and
bumped up pops to between 70-80% late Mon night through 18z tue
with pcpn tapering off and ending west to east late Tue aftrn
and Tue night as the deepest moisture pushes offshore. Added
moderate rain and slight chc thunder for Tue morning. Later
shifts can adjust as needed. Warm and humid Mon nite with lows
in the 60s. Breezy Tue with highs 70-75. Cooler Tue nite with
lows in the upr 40s west to upr 50s along the coast.

Slight chc pops Wed as upr level energy lingers. Cool with
highs in the low to mid 60s. The upr level low lifts NE thu
allowing high pressure to build across the southeast. Dry thurs
and fri. Highs thurs in the low to mid 60s. Lows in the 40s.

Highs Fri 65-70.

Aviation 12z Saturday through Wednesday
PredominantlyVFR conditions expected through the 12z taf
forecast period as sfc high pres dominates. Another round of
patchy areas of fg expected through early this morning... W
potential for ifr lifr from time to time... ESP phf ecg. Sfc hi
pres shifts off the coast tonight-sun. A little better coverage
of fg possible late tonight early Sun due to light SE winds. A
cold front is forecast into across the local area late Mon night
and Tue W chcs for MVFR to LCL ifr conditions in ra and low
cigs.

Marine
A large area of surface high pressure over the region will allow for
generally benign conditions over the waters through the weekend.

Winds generally are 5 knots or less over all of the coastal waters
this morning. Winds become ene by this afternoon and increase to 5
to 10 knots. Seas are expected to range from 1 foot or less in the
bay and rivers (1 to 2 feet at the mouth of the bay) and 2 to 3 feet
over the coastal waters. Favorable boating conditions continue into
Sunday with with benign seas and ese winds of 5 to 10 knots.

The next chance for significant weather over the waters does not
come until early next week as a strong cold front approaches from
the west on Monday and slowly crosses the waters on Tuesday. The
pressure gradient will lead to increasing southerly flow ahead of
the front later Monday into Tuesday, shifting to the wnw behind the
front Tuesday night into Wednesday. Small craft advisories will
likely be needed for most or all of the area Mon night Tue as the
pressure gradient should be strong enough for winds of 15-25 kt with
higher gusts. Coastal seas build to 6-9 ft with waves of 3-5 ft in
the bay likely. A fair amount of uncertainty remains Tue night wed
regarding how strong the pressure gradient will be as the models
tend to keep the cold air and strong winds off to our NW over the
great lakes until thu.
