Synopsis
A weak front will diminish over the local area this evening.

High pressure builds over the area for Monday. Tropical cyclone
humberto is forecast to track well east of the southeast coast
Tuesday through Wednesday. Meanwhile, high pressure gradually builds
down into the region from the north Tuesday night through
Thursday.

Near term through Monday
As of 355 pm edt Sunday...

latest analysis indicates a weakening frontal boundary bisecting
the CWA from SW to NE now starting to diminish. There is also
an inverted sfc trough along just off the coastal carolinas.

Skies this aftn are variably partly cloudy. Best chance for
showers isolated tstms late this aftn will be across the coastal
md va eastern shore, gradually shifting S into interior SE va ne
nc through sunset. Becoming mainly dry after sunset. Still
fairly humid and warm overnight for mid-sep, with lows ranging
from the mid to upper 60s across most of the area (some lower
60s in the piedmont and eastern shore). Patchy fog looks likely
after 06z through 12 13z across south central va NE nc so have
included this in the gridded forecast.

High pressure briefly builds in on Mon with ample sunshine and
very warm temps with highs expected to range from the upper
80s lower 90s inland to the mid 80s along the coast. Given
recent trends in high temperatures and fairly dry soil moisture
have sided on the high end of numerical guidance.

Short term Monday night through Wednesday
As of 355 pm edt Sunday...

a mostly clear sky will become partly to mostly cloudy mon
night into Tue morning, as high pressure building down from se
canada pushes a backdoor cold front down into the area. Lows
mon night will range from the mid 60s to lower 70s. Trends are
for the front to be a little slower to drop through the region
on tue. Not much in the way of deep layer moisture so will keep
pops only about 30-40% tue, though skies should become mostly
cloudy from N to S through the day. With the increase in clouds
and NE to E winds, high temps will be much cooler than mon
(especially over the north). Current forecast will have highs
75-80f N and 80-85 S (warmest for interior NE nc and south
central va). Slow clearing from NE to SW Tue night. Mixing and
some lingering clouds will keep it from getting really cool.

Thus, lows will avg in the 60s S and central to 55-60f n. High
pressure continues to build S from the eastern great lakes new
england on wed. Soundings show some lingering low level
moisture with the onshore flow so will keep it partly sunny
rather than sunny for most areas. Still should be dry though,
along with comfortable temperatures (highs only 75-80f) and dew
pts falling into the 50s for most areas. It will be fairly
breezy along the coast due to the cooler airmass over the warm
waters and a string pressure gradient between humberto well off
to the SE and the high centered to the N ne.

Long term Wednesday night through Sunday
As of 355 pm edt Sunday...

a ridge of high pressure will extend along the eastern seaboard on
Thursday with TS humberto located well off the east coast. High
pressure at the surface centers over the mid-atlantic beginning on
Friday and persisting into the next weekend. Aloft, a ridge of high
pressure will be building across the region from the southwest.

Nice weather is expected for much of the extended period with partly
to mostly sunny skies and dry conditions. High temperatures Thursday
and Friday will be near to slightly below seasonal averages with
highs in the upper 70s to lower 80s. Overnight lows will be on the
cooler side with temperatures falling back into the low to mid 50s
away from the coast and low to mid 60s at the coast. A warming trend
begins Saturday into early next week with high pressure at the
surface and building heights aloft. Above average temperatures
likely prevail through this period with highs in the mid upper 80s
to around 90 degrees.

Aviation 00z Monday through Friday
As of 655 pm edt Sunday...

a weak boundary will linger INVOF fa overnight into mon.

Clearing occurring now... Low level moisture remaining
abundant... Light vrb winds and climo will likely lead to at
least patchy fg after midnight (through about 12-13z 16). The
most widespread fg is likely to be over south central
va interior NE nc with less of a chc at main terminals. Did
include bkn ifr CIGS ecg ric sby (maybe phf should be included
as well) W MVFR vsbys (except orf). Otw... ExpectVFR conditions
for the rest of the day Mon with winds 5-10 kt or less. Low
level moisture will bring a chance for MVFR CIGS Tue tue night
along with somewhat breezy onshore (ene) flow near the coast.

BecomingVFR wed-fri under dry conditions.

Marine
As of 330 pm edt Sunday...

generally quiet marine conditions this afternoon as a weak cold
front moves through the region. Winds are generally 5-10 knots with
waves around 1 ft and seas 3-4 ft. A mixture of wind directions
noted this afternoon across the marine zones as the front makes slow
southward progress. Behind the boundary, winds are generally north
and northwest 5-10 knots across the northern ches bay while east and
northeast winds are present to the south. This boundary is forecast
to stall and lose definition this evening and tonight.

A strengthening tropical storm humberto is located around 200 miles
east of daytona beach, fl, moving slowly northward but is
expected to turn to the northeast and farther away from the
coast later tonight. Humberto is forecast to track ene well off
the southeast coast Tuesday into Wednesday as high pressure
builds across new england. This will produce a relatively tight
pressure gradient over the region, with the potential for a
15-25kt NE wind (highest for the SRN ocean zones and lower bay).

Seas are expected to build to 5-8ft Tuesday night and remain
elevated through at least Friday (if not into the upcoming
weekend). SCA conditions are expected for the ocean beginning
Tuesday afternoon, and lasting potentially into the weekend,
while SCA conditions are probable in the lower bay lower
james sound later Tuesday into Thursday.

Rip currents will continue to be an issue this week and into the
upcoming weekend as a combination of wind waves from the steepening
pressure gradient and long period swell from TC humberto impact the
region.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
