Synopsis
Low pressure moves east near the virginia-north carolina line
late this afternoon and evening while a cold front drops south
across the area. Both the cold front and low pressure pushes
south and east of the area later tonight. Canadian high
pressure builds into the region through the mid week period.

Near term tonight
As of 245 pm edt Monday...

latest msas has the low over swrn va with the cold front sagging
south across NRN va. Will keep the forecast as is (per latest
high res data). Expect sct convection to develop out ahead of
both the low and cold front over the next svrl hrs with slght
chc thunder south of a fvx-ric-phf line through 23z, then shifting
the convection south into nc arnd 00z.

A secondary upr level system rotating south behind low will keep
more of a stratiformed rain going through most of the night. Data
indicates the rain tapers off then ends late across the nwrn half
of the local area. Nne winds increase as the pres gradient tightens
btwn the deepening low and high to the north. Becoming breezy to
windy along coastal sections. Temps by 12z drop into the mid 30s
north to low-mid 40s south.

Short term Tuesday through Thursday night
As of 245 pm edt Monday...

altough the deepening low pulls farther offshore tues, moisture
fields show some light rain lingers along the sern coastal zones
thru 15z or so. Thus, will keep low chc pops across those areas
early. Otw, canadian high pressure builds SE from the gt lakes
region tues aftrn. Rather tight pressure gradient btwn the offshore
low and the high to the north keeps a stiff NE wind blowing along
the coast. NE winds 25-35 mph ERN shore to 35-45 mph sern coastal
areas (wind advsry along the SE coast). Mstly sunny most areas
except bcmg pt to mstly sunny across the se. Cooler despite the
sunshine. Highs 50-55 west of the bay, 45-50 near the water.

Clear and cold once again tues night with slowly diminishing winds
along the coast. Lows upr 20s-lwr 30s except mid 30s at the beaches.

The high moves into new england Wed with it extending SW along the
mts Wed nite thurs. Dry conditions expected thru the mid week period
along with a slow warming trend. Highs Wed in the 50s except upr 40s
to near 50 at the beaches. Lows Wed night in the 30s. Highs thurs
upr 50s-lwr 60s west of the bay, lwr-mid 50s near the water. Lows
thurs nite in the 40s.

Long term Friday through Sunday
As of 245 pm edt Monday...

high pressure becomes nearly stationary off the coast late in the
week. As we enter backdoor cold front season, one such front is
progged to remain north of the local area through sat, keeping the
area warm and dry. Highs Fri in the upr 60s-lwr 70s west of the bay,
60-65 near the water. Lows Fri nite 45-50. Highs Sat 70-75 west of
the bay, in the 60s near the water.

Low pressure tracks NE of the area Sat night allowing a trailing
cold front to cross the area sun. Chc pops with this feature late
sat night and sun. Lows Sat nite upr 40s-lwr 50s. Highs Sun in the
60s to near 70 south. Lows Sun nite upr 30s-mid 40s. Some model
disagreement as to how quick the front and assctd pcpn exits the
coast. GFS quicker than ecmwf. Will lean toward a dry and cooler
mon. Highs 55-60.

Aviation 19z Monday through Saturday
As of 130 pm edt Monday...

vfr conditions to start off the forecast period as high and mid
level cloudiness thicken up ahead of an apprchg low and strong
cold front. Shwrs from both the low and ahead of the front will
overspread the area before 00z but CIGS vsbys with these should
only drop into the MVFR category. A tstrm is also possible thru
00z at most TAF sites except sby with the fropa, but did not
include any thunder ATTM given no thunder is noted on any radar.

A secondary upr level low will follow the front tonight where
more of a stratiformed rain will occur with CIGS lowering to
near ifr levels but kept cigs AOA 1k ft for now. The next forecast
concern will be gusty nne winds behind the entire system as the
pressure gradient tightens btwn the deepening low moving offshore
and high pressure to the north. Winds will drastically increase
along the coast and become gusty along the coast after 06z
tonite. Gusts 15-20 kts at ric, 15-25 kts at sby with 20-30 kts
at phf, 30-40 kts at both orf and ecg. Skies slowly clr by the
end of the forecast period.

Outlook:
vfr conditions return through the end of the week as high
pressure builds to the north of the area mid week and over the
area by late week.

Marine
As of 200 pm edt Monday...

a weak frontal boundary is draped across the northern neck and lower
md eastern shore this afternoon. Winds along and north of the
boundary are ene at 10 kt or less and south of the boundary are s-sw
around 10 kt. Low pressure over eastern ky tn will approach from the
west late this afternoon, before sliding across nc this evening and
emerging off the mid-atlantic coast early Tuesday morning. As the
low approaches, the aforementioned front will dive south across the
waters late this afternoon evening, with winds quickly turning to
the nne post-frontal. Strong north and northeast flow will follow
the frontal passage with scas already in place for the northern ches
bay, rivers and coastal waters north of parramore island. Farther
south, gale warnings remain in effect for the coastal waters south
of parramore island, the lower ches bay and currituck sound through
much of Tuesday. Have also added in the lower james river to the
gale warning starting at midnight. Winds in the gale warning will
run nne 25-35 kt with gusts up to 40 kt. Within the scas, nne winds
20-25 kt with gusts to 30 kt.

Sfc low pressure still looks to slow linger offshore Tuesday night
and early Wednesday, allowing scas into Wednesday, at least over
over the lower bay and lower james... With winds across northern
waters slow to diminish into Wednesday. Over the coastal waters,
seas quickly build tonight and Tuesday, with persistent strong ne
winds building seas considerably (5-8 feet N and 6-10 feet s) on
Tuesday. A high surf advisory has been issued from va beach south to
outer banks currituck in response to building seas during this
period. Even after winds diminish with slackening pressure gradient
late Wednesday, an extended period of elevated seas appear likely
over the coastal waters for much of the week ahead, given prolonged
onshore flow continuing through midweek. Marine conditions finally
start to improve later Thursday and Friday... As high pressure builds
over the southeast and winds turn offshore later Fri into
Saturday.

Tides coastal flooding
As of 200 pm edt Monday...

a high surf advisory has been issued from va beach to outer
banks currituck for breaking waves around 8 feet, which will
result in some beach erosion and dangerous surf conditions.

Although not anticipated at this time, some minor tidal flooding
may occur across the lower ches bay and lower james river
(sewells pt) during high tide Tuesday afternoon.
