Synopsis
An area of low pressure moves along a cold front tonight, with
canadian high pressure building into the mid-atlantic from the
north later Wednesday afternoon into Wednesday night. High
pressure remains over the region Thursday and Friday.

Near term until 6 am Wednesday morning
As of 300 pm edt Tuesday...

current GOES wv imagery depicts a shortwave trough moving into
the mid-south in wsw flow aloft. Meanwhile, a cold front has
pushed through the local area and stalled across nc. Mostly
cloudy and cool this aftn with temperatures ranging through the
60s. The upper wave will approach from the wsw with moisture
spreading across the region N of the front by later this
evening. Light rain is expected to move into the piedmont later
this evening, and then expand and spread ewd toward the coast
overnight. Pops are mainly 60- 70% along and S of a line from
fvx-ric-wal and 40-50% N of that line. QPF will mainly be light,
generally 0.1-0.25", and 0.25-0.4" for far SE va NE nc. Lows
tonight range from the upper 40s NW to around 60f se.

Short term 6 am Wednesday morning through Friday
As of 300 pm edt Tuesday...

canadian high pressure to the NW will push the stalled front
off the coast by Wednesday aftn. Rain will linger over SE va ne
nc through about 12z 8am Wednesday morning, and then gradually
taper off through noon over coastal NE nc. Otherwise, clearing
from nw-se with most locations becoming mostly sunny by aftn.

Highs range from the upper 60s N to the low or even mid 70 S as
caa will be slow to arrive Wednesday. Wednesday night will
likely be the coolest night of the season thus far with cool
high pressure building over the region and a clear sky. Lows
will likely drop into the mid-upper 30s to low 40s for the
piedmont into portions of the interior coastal plain and mid 40s
to low 50s at to the coast of SE va NE nc.

Sunny and cool Thursday with high pressure over the region.

Highs are forecast to be in the upper 50s to around 60f, with
dewpoints in the low 30s. Even cooler Thursday night into Friday
morning as 1030mb high pressure settles over the region.

Forecast lows are in the mid 30s for the piedmont, interior
coastal plain, and interior md ERN shore (upper 30s for urban
areas), and some colder locations potentially could drop to 32f
given ideal radiational cooling conditions and a dry airmass.

Elsewhere, lows should be in the upper 30s to low 40s, with mid
40s at the coast in SE va NE nc. High pressure gradually slides
offshore by Friday aftn. Increasing clouds with highs in the low
to mid 60s.

Long term Friday night through Tuesday
As of 300 pm Tuesday...

at the start of the extended period, a rather vigorous
shortwave trough drops southeastward from canada (along w
associated sfc low pressure coupled with a cold front). As the
cold front approaches the area Fri night-Saturday, subtropical
moisture will stream from the gulf coast to the carolinas srn
mid-atlantic as we briefly go under wsw flow aloft. The
combination of moisture returning, an approaching cold front,
and a series of mid-level disturbances moving from wsw to ene
along the front will allow rain chances to increase throughout
the region. Thus, will maintain pops of 40-50% increasing to
60-70% for much of central south-central va Fri night. As the
front crosses the region during the day on Saturday, the highest
rain chances will shift to the southeastern CWA by the early
afternoon. Maintained categorical pops across SE va NE nc from
12- 18z sat, as the 16 12z gfs ECMWF gem continue to paint a
widespread area 0.25-0.75" of rain south and east of an avc-akq-
mfv line. Lows Fri night in the low-mid 50s ahead of the front.

Forecast highs on Saturday range from the mid-upper 60s. Rain
chances rapidly go down after 20z Sat as the front pushes
southeast of the cwa. Skies quickly clear Sat night as drier air
moves in from the N nw. Lows will range from the low-mid 40s nw
to the low 50s in coastal SE va NE nc.

Expect dry weather to prevail for the remainder of the extended
period. Low-level CAA continues on Sunday (850hpa temperatures
will range from -1c to -4c by the end of the day. Sfc high
pressure moves overhead Sun night. Highs only in the mid-upper
50s on Sunday. With the high (nearly) overhead, expect a cold
night across the area, with mid-upper 30s inland 40s along the
immediate coast. Winds turn back to the south by Mon pm,
allowing for a very slight warm-up. Low pressure (sfc-aloft)
passes well to our north on Tue tue night. This will drag
another cold front through our area late tue-wed. However, this
will likely be a dry fropa. Highs in the upper 50s-low 60s on
mon rising into the mid 60s area-wide on tue, with morning lows
in the upper 30s-mid 40s on tue.

Aviation 00z Wednesday through Sunday
As of 740 pm edt Tuesday...

a cold front is situated over southern nc as of 740 pm, with
e NE winds below 10 kt at all of the terminals. A large area of
-ra ra extends from WRN va nc to southern va. CIGS have lowered
to between 2-3k feet throughout much of central southeast va
and NE nc. At sby, CIGS remain around 5k feet. The area of rain
will progress east-northeastward through the night as weak sfc
low pressure tracks along the front from SRN nc to near cape
hatteras before moving offshore by 09-12z Wednesday. Expect
mainly light to moderate rain at the terminals, with cigs
falling to low-end MVFR or even ifr (briefly) later tonight into
early Wednesday morning. The lowest chance of rain (~50%) is at
sby, with -ra ra likely elsewhere. The rain should exit ric sby
by ~09-10z, with rain chances lingering across the southeast
through 12-15z. Clearing is expected from NW to SE later
Wednesday morning along with a wnw wind increasing to ~10 kt.

There is the potential for winds to gust to 15-20 kt at ric sby
Wednesday afternoon.

Outlook... Cool and dry high pressure prevails Wednesday night
through Friday. Another cold front pushes through the region
Saturday bringing a chc of -ra. High pressure returns Sunday.

Marine
As of 300 pm edt Tuesday...

north winds have diminished this afternoon as the cold front
stays south of the area. Expect winds to become easterly this
evening, then southerly late as a weak low pressure system
develops along the front over the carolinas. This low will move
offshore by Wed morning allowing winds to turn nw. Northerly
winds quickly increase to 20 to 25 kt with gusts to 30 kt across
the entire coastal waters and bay early Wed evening as strong
high pressure builds in from the great lakes. Seas will quickly
build to 5-6 ft over the ocean and 3-5 ft bay. A small craft
advisory will likely be needed. Winds slowly subside Thu into
thu night as the center of the high moves over the middle
atlantic. The high shifts offshore for Saturday, allowing for
increased south-southwest winds of 15-25kt before another cold
front passes Sat night into Sunday.

Hydrology
As of 300 pm Tuesday...

numerous river flood warnings continue on the nottoway,
meherrin, appomattox basins. Also, have re-issued the areal
flood warning for locations along the mattaponi river where the
level is still steady or slowly rising at beulahville and a new
warning for bryants corner SE of kemv. See flwakq flsakq for
site-specific details.
