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
As of 3 pm, ric orf ecg all have broken the record high for today.

Rer's to be issued later this aftrn.

Latest msas shows that the shallow backdoor front has stalled along
the differential heating boundary this afternoon, basically along a
i64 va st rt 360 line. Interesting to note the temp diff across the
ric metro area with upr 50s NW to mid 70s at the airport. Pt sunny
and warm south of it with temps in the 70s to near 80 while north of
it remains cloudy and cooler with spotty light rain. Temps stuck in
the 50s and 60s.

Latest data moves a trof across pa east this eve. A secondary surge
behind that feature (along with diminishing mixing) should be enough
to push the shallow backdoor bndry south to near the va nc border by
late evening with it stalling out across NRN most nc zones thru the
nite. Thus, trended the grids towards this scenario with skies
becoming ovc with chc light rain. Drizzle and patchy fog after
midnite as the column saturates. Lows in the low-mid 40s north, upr
40s-lwr 50s south.

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 20z Thursday through Tuesday
The backdoor cold front will slowly sag south to near the va nc
border this eve then stall across NRN nc tonight before lifting
north as a warm front fri. Stratus stubborn to scour out south
of the front ATTM but do expect MVFRVFR CIGS across sern taf
sites next svrl hrs ahead of the fropa. To the north at ric sby
MVFR CIGS lwr to ifr by 00z along with some fog drizzle for the
rest of the forecast period. Ifr conditions expected at all taf
sites later tonight through Fri morn along with patchy drizzle
and fog.

Outlook: the front moves north of the area Fri night with the
offshore ridge dominating Sat into sun. The next front will
cross the area Sunday night, with another period of cig vsby
restrictions possible during this period.

Marine
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.
