Synopsis
Strong low pressure just off the north carolina early this
morning will track east out to sea today into tonight. However,
a second low will develop off the southeast coast late tonight,
then will slowly push out to sea during Tuesday. High pressure
will build over the area Tuesday afternoon through Wednesday.

Near term through tonight
As of 420 am est Monday...

early this morning, strong low pressure was just off the nc
coast. Latest radar showed lingering light very pcpn over the
srn half of the cwa. Light very light mixed pcpn (snow freezing
drizzle) was occurring over south central va counties along and
west of i-95, with just light very light rain occurring over se
va and NE nc. Due to this lingering light very light mixed pcpn
this morning and temps still below freezing in south central va
counties, have issued a winter weather advsy until 11 am this
morning. Temps will rise above freezing for late this morning
thru this aftn.

Due to the extensive heavy snow accumulations inland, esply over
central south central va, and into the va NRN neck, travel will
remain very hazardous dangerous thru this morning, and some roads
could still be impassable or even closed. Thus, will issue an
sps to account for this and temps below freezing.

Otherwise, expect improving conditions acrs most of the area
from late this morning through tonight, as high pressure starts
to build in fm the nnw. However, lingering low pressure off the
coastal carolinas will maintain more clouds and chance to low-
end likely pops from extrm scntrl SE va and NE nc. Highs today
will range fm the mid to upper 30s over the piedmont inland
areas, to the lower to mid 40s near the bay coastal areas. Lows
tonight will range through the 20s across most of the area
(with a few upper teens possible over the piedmont). Near the se
va nc coast, lows will avg 30-35.

Short term Tuesday through Wednesday
As of 420 am est Monday...

remaining below normal for temps Tue and wed, but expect it to
be dry and partly to mostly sunny. Highs in the 40s and lows in
the 20s.

Long term Wednesday night through Sunday
As of 255 pm est Sunday...

strong amplification of trough aloft through the ms valley
expected Thu which will progress E Fri through sat. Milder air
along W increasing moisture will be spreading NE into the mid-
atlantic region ahead of potent lo pres and its associated cold
front (beginning late thu). That lo pres system is expected to
track into the oh valley Fri fri night... Then continue into new
england during next weekend. Ramping up pops (to 70-90%) from
fri morning into Fri night... Then will the cold front pushing
off the coast on sat... Will be lowering pops (from w-e).

Lows Wed night from the m-u20s inland to the m30s along the
coast. Highs Thu in the l-m40s W to the u40s-l50s e. Lows thu
night in the l-m30s inland to the m40s at the coast. Highs fri
from the l50s far W to the l60s in far SE va-ne nc. Lows fri
night in the 40s... Except l50s at the coast in SE va-ne nc.

Aviation 09z Monday through Friday
As of 100 am est Monday...

early this morning, pcpn has ended at ric and sby withVFR
conditions at these sites. At phf, orf, and ecg, ifr to MVFR
cigs were lingering with -ra occurring. Light rain will persist
at these sites into this aftn and early this evening, but cigs
will improve toVFR, as the storm pushes out to sea. Also, NE or
n winds will diminish today into this evening.

Low pressure will linger off the coastal carolinas into tue
morning, resulting in locally breezy conditions possible for
ecg orf. High pressure prevails Tue aftn into thu.

Marine
As of 420 am est Monday...

low pressure is centered off the outer banks early this morning.

The wind is primarily NE 20-30kt for the majority of the marine
area, and remains 30-40kt S of CAPE henry. Gale warnings for
the lower bay lower james and ocean from parramore is. To
chincoteague have been replaced with scas. Gale warnings
continue through 7 am from parramore is. To the va nc border,
and a storm warning will continue through 7 am off the currituck
outer banks. Seas are 5-8ft n, to 12-18ft off the NE nc coast,
with 3-5ft waves in the bay and 5-7ft at the mouth of the bay.

Scas continue into Tuesday for the NRN ocean zones, tonight for
the bay, this evening for the lower james, and later this
morning for the remaining river. Overall, the wind should
gradually diminish today into tonight as the gradient slackens.

However, brief re-development is expected off the outer banks
tonight, which could locally enhance the wind for the SRN ocean
zones and the sound. Seas will remain 5-8ft N to 10- 15ft s
today, and gradually subside tonight into Tuesday.

High pressure returns Tuesday into Wednesday. Another low pressure
system will push through the region later in the week bringing the
potential for SCA conditions.

Tides coastal flooding
As of 420 am est Monday...

low pressure will linger off the carolina coast today. A strong
ne wind will continue and is expected to push tidal anomalies
to 2.0-2.5 ft above normal for outer banks currituck where
moderate tidal flooding is possible during high tide this
morning. Tidal anomalies are expected to be 1.5-2.0ft above
normal from the lower bay into va beach where minor flooding is
possible during high tide this morning. Additionally,
substantial beach erosion is expected due to large breaking
nearshore waves. A high surf advisory will remain if effect for
va beach and outer banks currituck today.
