Synopsis
Low pressure and an associated cold front push south and east
of the area later tonight. Canadian high pressure builds into
the region through the mid week period.

Near term until 6 am Tuesday morning
As of 640 pm edt Monday...

latest sfc analysis reveals that low pressure over SW va
earlier this aftn is now centered over far SE va ERN nc. Wv
satellite imagery shows an upper shortwave diving SE across the
ohio valley. Rain has overspread the southeastern two-thirds of
the cwa, with a few embedded tstms over far SRN va NE nc.

Temperatures are still in the upper 60s over NE nc while
readings are mainly in the 55-60f range over central va (where
winds have turned to the n). Temperatures have fallen into the
50s from orf-ntu to the lower ERN shore (where the flow has
increased out of the E ne).

Rain will end from NW to SE over the NW two-thirds of the cwa
from 00-06z tonight as the low moves offshore. Rain will likely
continue through most of the night over the southeast third of
the CWA as the aforementioned upper shortwave dives into the
carolinas. QPF amounts (from 00-12z tue) range from a few
hundredths of an inch NW to 0.50-0.75" over SE va NE nc. The
sfc low deepens as it continues to move offshore as high
pressure builds into the WRN great lakes late tonight. The
resulting pressure gradient between the deepening low and high
to the NW will allow n-ne winds to become gusty to 40-50 mph
over coastal SE va NE nc late tonight. Expect nne winds to gust
to 20-40 mph in most other locations (still highest near the
coast). Overnight lows range from the mid 30s north to low- mid
40s south.

Short term 6 am Tuesday morning 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 Monday
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 00z Tuesday through Saturday
As of 755 pm edt Monday...

low pressure over NE nc is moving to the E while an area of rain (w
embedded heavy shras) is centered over ERN va. CIGS areVFR (~5k ft)
throughout most of the area (with a few obs showing bkn ifr
cigs INVOF phf), while prevailing vsbys are MVFR in the rain.

There have been a few brief periods of ifr vsbys in the heavier
shras. Expect the rain to end from NW to SE tonight. While rain
will likely continue at ecg (and possibly orf) through much of
the night, the intensity will diminish (especially after 03z).

There is a slight chc of thunder at ecg, but did not include
this in the taf. Sby will likely remain (mainly) dry tonight.

Confidence is moderate-high that prevailing CIGS will drop to
MVFR levels at ric phf orf ecg by around 03z, while remaining
vfr at sby. Prevailing ifr CIGS are likely ecg from 06-12z (with
a slight chc of ifr CIGS at orf). DryVFR conditions return to
all terminals (except ecg) by 12z tue, while ecg may remain MVFR
(due to cigs) until midday. Skies clear out by late Tue aftn.

Winds have already shifted to the n-ne at all terminals, and will do
so at ecg in the next few hours. These n-ne winds are expected to
increase and become quite gusty near the coast after 06z tonight as
the aforementioned area of low pressure deepens as it tracks
offshore. Expect gusts of around 20 kt at ric sby, 25-30 kts at phf,
and 30-40 kts at orf ecg.

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.
