area forecast discussion

804 pm est Thu feb 22 2018

Synopsis
A frontal boundary stalls across the region tonight, then lifts
back north as a warm front Friday. Another cold front crosses
the area late Sunday.

Near term until 6 am Friday morning
Dramatic drop in temperatures have occurred over SE and parts of
srn va the past couple of hours as backdoor cold front makes
push s. Readings... After being in the 70s... Down in the u40s to
50s while warm sector remains over far south central va and ne
nc. The shallow front to keep pushing S this eve... Eventually
through NE nc. Additionally... Lo CIGS (st) along and N of the
front... And will be adding fg near the coast. Patchy areas
of -dz overnight. NE winds now gusty to 20-30 mph as colder air
spreads s... Should wane a bit overnight.

Short term 6 am Friday morning through Sunday
Models are fairly quick to move the boundary back north as a warm
front fri. Plenty of low level moisture noted to keep low chc
stratiformed pops across the north thru 18z, then the lower levels
dry out a bit as the fa becomes warmed sectored. Another tricky temp
forecast as the numbers will depend on how much Sun occurs. Highs in
the low-mid 50s north, upr 50s-mid 60s south, 65-70 across NRN nc.

Fa remains in the warm sectored Fri nite. Not much support for pcpn
but fog will be a good bet, especially after midnite. Lows 45-50
north, in the 50s south.

Offshore ridge builds back into the area sat. Moisture slowly incrs
with the best support for pcpn across the NW Sat aftrn and eve. Otw,
pt suny to mstly cldy and warmer. Highs in the low-mid 60s ERN shore
with the 70s west of the bay. Lows Sat nite in the lwr 50s-lwr 60s.

The next cold front approaches from the west Sun morning with the
fropa in the aftrn eve. Models depict a decent feed of moisture
across the mts but it weakens as it moves east into the piedmont.

Will keep the chc pops after 18z for now. Highs in the 60s ern
shore, 70s west of the bay.

Long term Sunday night through Thursday
No major changes expected the the day 4-7 forecast. Still expecting
a cold frontal passage Sunday night into Monday. The front will be
slowing down as it approaches the area as it becomes nearly parallel
to the upper flow aloft. As such, will need to maintain chance pops
sun night into Monday for all locations. Am expecting everyone to
see some light rain at some point, and guidance pointed to likely
pops both Sun night into Monday. However, given that the rain will
be light and not continuous, we opted to just include chance of rain
showers for that period. Once the front moves south of the area, dry
canadian high pressure will build across the middle atlantic by
Tuesday, then offshore wed. The next chance for showers will be
Thursday as the guidance suggests strong warm advection ahead of a
deepening mississippi valley low pressure system.

Despite the cool down from this week, temperatures will still be
above normal with temperatures in the upper 50-mid 60s and lows in
the upper 30s mid 40s.

Aviation 01z Friday through Tuesday
Backdoor cold front now S of all sites except for ecg... That
will occur most likely by 03-04z. Period of st... Ifr lifr cigs
and -dz into through Fri morning beore CIGS slowly gradually
rise (to at MVFR - slowest to occur at sby) as front retreats
back N as warm front Fri afternoon eve. Region back into the
warm sector Fri night-sun (though there may be sct shras). The
next front will cross the area late sun... W another period of
cig vsby restrictions possible during that period.

Marine
Went ahead and put up a small craft advisory for all of the bay
and lower james until 06z. Winds are gusting out of the N NE in
excess of 20 knots with the surge behind the front. Winds should
begin to lighten up after 06z. Also went ahead and expanded the
small craft advisory in the ocean to include parramore island to
cape charles light as seas will likely build to 5 feet in
portions of the zone and a few gusts to 25 knots can't also be
ruled out. Finally, issued a dense fog advisory for the lower
bay, southern ocean zones, and currituck sound until 06z per
recent observations and cams.

Previous discussion: the front is currently bisecting the
marine area as it has been slow to move southward this afternoon
due to the strong ridge to the south. However, after sunset,
expect the front to rapidly move southward, reaching the
southern coastal waters by later this evening. All marine areas
should have northerly winds tonight. Will maintain small craft
conditions across the northern coastal waters tonight due to
wind and seas, however even the bay will will choppy with north
winds around 15kt.

Expect the front to surge back north of the waters on Friday Friday
evening , with southerly flow developing and continuing through the
weekend. By Saturday night into Sunday, southerly winds may allow
for small craft conditions again over the coastal waters ahead of a
cold front. This cold front will pass through the waters on Monday
with NW winds expected Tue Wed as canadian high pressure builds into
the ohio tennessee valley regions.

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.
