Synopsis
A cold front will approach from the west tonight, with an area
of low pressure intensifying along the front Thursday morning. The
trailing cold front crosses the area Thursday afternoon. High
pressure builds in again for the weekend.

Near term until 6 am this morning
As of 830 pm est Wednesday...

warm front has made it through most of the fa... W only far wnw
areas (well wnw of ric) still hanging onto sfc cold air wedge.

Breezy and warm elsewhere W mostly cloudy conditions w... Partly
cloudy e. S winds will remain gusty to 20-30 mph overnight... Highest
e of I 95 to the coast. Both kakq and kdox radars currently
down so determining pcpn coverage difficult. Sfc obs void of any
-ra so far. Using nearby radar to the W and s... Some patchy -ra
appears to be moving slowly E in WRN va... And slowly N in nc.

Based on near term hi res model guidance... Continuing the trend
of slowly raising pops mainly w-e overnight... Eventually to
80-100% far W and 20-40% at the coast. Lows are generally near
current values... From the l-m40s far wnw to the 50s elsewhere.

Short term 6 am this morning through Saturday
As of 350 pm est Wednesday...

the low tracks NE along the advancing cold front Thu morning
with the trailing cold front crossing the area through the day,
pushing offshore by 21z Thu to 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 locally heavy downpours. Thus, continued with some
r+ for a 3-6 hr period. Also see the potential for brief wind
gusts to 35-45 mph sometime from 12-15z give or take an hr or
two. Opted against a wind advisory in favor of issuing sps's as
the duration is expected to be only 1-2 hrs. If a wind advisory
were to be issued by next shift, would likely be the eastern
shore and far SE va NE nc. Pcpn quickly tapers off to some
light rain or showers Thu aftn west to east as the front pushes
all the deep moisture towards the coast. Mild with highs upper
50s NW and most of the eastern shore to lower-mid 60s most other
places. QPF will avg 0.75" to 1.25".

Clearing and colder Thu night as weak high pressure briefly builds
in from the nw. Lows mid upper 20s NW to mid 30s se. A trailing
upper level shortwave will cross the area on Fri and after a
sunny start will see some clouds develop by late morning early
aftn. There will be decent lift due to the upper energy aloft,
but low levels look very dry so did not add any pops at this
time (though will need to watch this closely as a 20% pop may be
needed). Back to near normal temps Fri with highs mainly in the
40s and then below normal temps Fri night (lows in the upper
teens to mid 20s) and Sat (highs upper 30s to lower 40s) as
cold high pressure builds in and settles over the region.

Long term Saturday night through Wednesday
As of 350 pm est Wednesday...

fairly quiet conditions for much of the extended period in our area.

An upper level disturbance skirts north of the area during the day
on Sunday which may lead to some light precipitation across the far
northern portions of the area. Due to the lack of moisture, just
maintained a slight chance of pops across the north into Sunday
night. Warm air advection develops Monday into Tuesday as upper
heights build ahead of another great lakes low pressure system. The
associated cold front approaches the region late in the day on and
crosses the region early Wednesday bringing the potential for rain
or snow showers across the region. Much colder conditions work into
the region by Wednesday night.

Aviation 06z Thursday through Monday
As of 105 am est Thursday...

low pressure and an associated cold front will push ewd across
the mountains early this morning, and then arrive into the
region later this morning, before pushing offshore this aftn. A
strong pressure gradient ahead of this system will result in a
modestly strong S wind of 12-15kt with gusts to ~25kt early,
will then increase to 15-20kt with gusts of 25-30kt (locally up
to 35kt toward the coast). The potential for llws of 45-60kt
~2kft will continue early this morning, mainly for
sby phf orf ecg. The wind will become westerly in the wake of
the cold front with gusts to ~20kt. Light rain will overspread
the region from 08-12z, with a period of moderate to heavy rain
passing across the region later this morning through early aftn.

Generally MVFR CIGS are expected, with a low probability if ifr
cigs. A period of ifr vsby will likely occur with the heaviest
rain, and this will likely occur after 12z for the TAF sites.

Drier air quickly arrives behind the cold front this aftn with
rain ending from about 16-19z. Mostly clear by tonight with a nw
wind of 5-10kt.

A weak and dry cold front crosses the area Friday, with high
pressure building into the region Friday night through Monday.

Marine
As of 400 pm est Wednesday...

a digging upper trough from the central plains ewrd into the
oh tn valleys will result in sfc low pressure and an associated
frontal boundary will push into the area fm the west tonight
into Thu morning. Increasingly steep pressure gradient between
departing high pressure and the approaching low frontal
boundary will allow S winds to increase to 15-25 kt with gusts
to 30-40 kt very late tonight thru Thu morning. Have gone with a
gale warning for the NRN three coastal zns (650-654) from late
tonight into early Thu aftn, due to gusts to 35-40 kt in these
areas. Have maintained sca's for the remainder of the waters
into early Thu aftn, with gusts 30-35 kt possible at the mouth
of the ches bay, the currituck sound, and the SRN two coastal
zns. Waves will build to 3-5 ft in the ches bay tonight into
thu morning, with seas building to 7-12 ft.

Will have to monitor for the potential for a high surf advisory
on Thu from roughly CAPE charles light northward. Winds will
become NW behind the frontal boundary late Thu aftn. Cold
advection behind the front appears rather anemic with northwest
winds 10-20 kt in its wake, decreasing further Thu evening.

Seas will be slow to subside Thu into Fri morning, with sca's
for the coastal zns lasting into Fri morning.

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

Tides coastal flooding
As of 350 pm est Wednesday...

departures will continue to rise in the strong S flow through
thu morning (especially in the mid upper bay) but not expecting
any sites to hit minor flood thresholds at this time.

Equipment
As of 100 am est Thursday...

the kdox radar is currently down for a faulty azimuth motor.

Parts will need to be ordered and a return to service time is
unknown.

The kakq radar remains 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.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
