Synopsis
A series of low pressure systems will track northeast along the
mountains today and Thursday. The associated warm front lifts
north of the region later today with the trailing cold front
crossing the area Thursday. High pressure builds in again for
the weekend.

Near term until 6 pm this evening
As of 300 am est Wednesday...

latest msas has the arctic high well off the mid atlantic coast with
low pressure moving into il. Meanwhile, a warm front snaked it way
from the deep south north of the gom a dvlpg scndry low in ERN tx.

Models take the first low NE into the great lakes region with the
warm front slowly lifting north from the deep south. Latest data
suggests the front doesn't get this far north until closer to sunset.

Ahead of it, a return and moistening upslope flow will continue to
allow clouds to thicken up as the day progresses.

Some of the high res data showing vry light (upslope) pcpn dvlpng
across the piedmont (from avc-fvx). Already noting some echoes
aloft popping up west of dan. With temps AOB 32, still can't rule
out some vry light fz rain fz drizzle for an hour or two across
extreme WRN zones arnd 12z. Given, how low the dew points are, some
of this pcpn may ot be able to reach the ground. Thus, will keep
some frozen pcpn in the grids for now and monitor radar trends
over the next svrl hrs. Thinking here is that if any of this pcpn
does reach the ground, will be able to handle it with an sps given
little if any measurable pcpn xpctd. Otw, any rain chcs remain over
the piedmont today (generally west of i95) where low chc pops will
be maintained, dry elsewhere under cldy to mstly cldy skies. Temps
slow to rise this morn, but increasing southerly winds this aftrn
will allow temps to rise thru the 40s and 50s with the highs not
achieved until late aftrn.

Short term 6 pm this evening through Friday night
As of 300 am est Wednesday...

the warm front lifts north of the local area this evening leaving
the fa in the warm sector overnight. Meanwhile, moisture from the
second area of low pressure overspreads the region starting late in
the evening over the west then over the rest of the area after 06z.

Chc to low end likely pops this eve ramp up to high end likely and
categorical after midnight. Some mdt to lclly hvy rainfall enters
the piedmont late. Much warmer with nearly steady temps thru the
night from the mid 40s NW to mid 50s se.

The low tracks NE across the region Thu morning with the trailing
cold front crossing the area thru the day, pushing offshore by 00z
fri. Data shows a decent slug of SRN stream moisture combined with
strong lift btwn 12z-18z just ahead of the cold front. Some convective
elements noted for a band of lclly heavy downpours. Thus, added some
r+ for a few hr prd. Pcpn quickly tapers off to some light rain or
shwrs Thu aftrn west to east as the front pushes all the deep moisture
towards the coast. Mild with highs 55-60 north to 60-65 south. Can't
rule out some elevated thunder along the sern beaches in the aftrn,
but left thunder out of the fcst thinking it remains offshore closer
to the gulf stream wall. QPF arnd one inch.

Clearing and colder thurs nite as high pressure builds in from the
nw. Lows mid 20s NW to mid 30s se. Back to below normal temps fri
and Fri nite. Plenty of sunshine fri. Highs upr 30s NW to mid 40s
se. Lows Fri nite upr teens NW to upr 20s se.

Long term Saturday through Tuesday
As of 310 pm est Tuesday...

the extended looks fairly quiet at least for our region as the
main storm systems stay north or west of the area... Or well
offshore. High pressure over the area Saturday gradually shifts
ne through Sunday with the ridge axis staying in place across
the area. A weak upper disturbance moves well north of the area
later Sunday which may allow for some light precipitation
Sunday night, but given the lack of moisture will keep just a
slight chance of rain (or snow across the nw). Warm advection
again develops Monday into Tuesday as upper heights build ahead
of another great lakes low pressure system. The associated cold
front is expected to approach the area on Tuesday with chance of
rain across the west and north.

Highs over the weekend will be seasonably cool with temps in the
40s Saturday and mid 40s-lower 50s Sunday-Tuesday.

Aviation 08z Wednesday through Sunday
As of 1230 am est Wednesday...

high pres now offshore with low pres west of the mts. A warm
frnt lifts north of the local area after 12z. High level moisture
quickly overpreading the region ATTM with a mid level cloud deck
btwn 3-5k ft moving east of the mts and across the piedmont.

Vfr conditions expected thru most of the forecast period as any
moisture with the warm front is progged to stay west and north
of the TAF sites. Brought ric's CIGS down to bkn MVFR after 12z
being closer to the mid level moisture source. Any pcpn expected
to remain west thru 00z with only chc pops at ric after 03z. South
winds will increase thru out the day. Of note will be wind shear
tonight due to a strong low level jet. Expect south winds 40-50kts
at 2k ft after 00z.

Outlook...

low pressure and associated frontal boundaries will affect the
area tonight through thu. This system will likely bring more
rain and fog with ifr restrictions, especially from 06-18z 24
(thu). High pres briefly returns Thursday night... Before another
cold front sfc trough crosses the area on Fri (conditions look
to remainVFR Thu night into the weekend).

Marine
As of 300 am est Wednesday...

seasonally strong surface high pressure continues to move offshore
early this morning with winds across the marine area becoming
southerly at 5-15 knots. Waves are 1-2 feet in the bay with 2-4 foot
seas offshore.

A digging upper trough across the central portion of the country is
allowing surface low pressure to deepen across the mississippi
valley. Increasingly steep pressure gradient between the departing
high and approaching low will allow winds to increase in magnitude
through the course of the day and especially into the evening and
overnight hours tonight. Southerly winds in the bay increase to 15-
20 knots this afternoon with 20-25 knot southerly winds by this
evening offshore. Small craft advisories will begin for the bay and
northern offshore zones shortly after noon and the lower james,
currituck sound, and remaining offshore zones following suit a few
hours later. Winds and seas will increase further overnight into
Thursday as a secondary area of low pressure forms along the
trailing cold front. Winds in the bay will run 20-25 with gusts to
30 knots by Thursday morning while winds offshore increase to 25-30
with gusts to 35 knots. A few gusts could exceed 35 knots during
this period, especially across the northern offshore zones. Opted
not to issue a gale watch with this package due to the relatively
brief window for gale conditions and the less than climatologically
favored southerly wind direction, however, will continue to watch
this period closely in subsequent forecasts. Seas will build as
winds increase Thursday morning with 8-12 foot seas possible across
the northern offshore zones, slightly lower to the south where 5-9
foot seas are expected. Will have to monitor for the potential for a
high surf advisory on Thursday from roughly CAPE charles light
northward. Winds will become northwesterly behind the surface cold
front late Thursday afternoon. Cold advection behind the front
appears rather anemic with northwest winds 15-20 knots in its wake,
decreasing further Thursday evening. Seas will be slow to subside
Thursday and scas for offshore zones will likely need to be extended
into Friday to cover this threat.

High pressure builds into the region on Friday with tranquil marine
conditions in store through the upcoming weekend.

Tides coastal flooding
As of 455 pm est Tuesday...

water levels along the ocean zones from parramore island to cape
charles light at low tide dropped to around 1.5 ft below mllw
and are now rising. Still appears likely that these same zones
will drop more than 1 foot below mllw for the next low tide
cycle occurring early Wed morning. Will be issuing a new low
water advisory from 06-10z (1 am to 5 am est) Wed morning for
these zones elsewhere, water levels should remain just above
advisory criteria during the next low tide.

Equipment
As of 300 am est Wednesday...

the kakq radar is down due to a pedestal slip ring assembly
failure. Due to the time to procure ship the needed parts, and
the repair time, the radar will remain down through at least
Friday.
