Synopsis
High pressure remains centered just off the northeast and mid
atlantic coast today. Low pressure will track northeast up
and along the east coast Tuesday through Wednesday.

Near term until 6 pm this evening
As of 350 am edt Monday...

latest sfc analysis shows ~1030 mb high pressure centered just
offshore with ~1007 mb low pressure over tn. The high remains
just offshore today allowing for a mainly dry day as the low
stays put over the SE states. Some light rain is psbl over far
sw areas by mid aftn (20-30%) with no pops for the remainder of
the fa during the daytime period. High temps range from near 60
along the coast to the upr 60s inland.

Short term 6 pm this evening through Wednesday
As of 350 am edt Monday...

rain overspreads the fa tonight except for the lwr md ERN shore
where it may take until 12z Tue morning to reach. Pops ramp up
to categorical south of i64 tonight Tuesday morning, with high
end chc to likely pops to the north. Lows tonight upr 40s NW to
mid 50s se. Tue looks breezy and wet, courtesy of strong
(albeit slightly weakening) onshore flow and upper forcing.

Still appears enough lift moisture for periods of moderate to
heavy rainfall. Event total QPF 1-2". Highs Tue upr 50s NW to
mid 60s se.

Drier, albeit with lingering clouds for Wednesday. Slightly
warmer with some peeks of Sun likely. Still enough remnant low
to mid level moisture for a few showers, so will maintain chc
shower wording. Highs in the upr 60s to mid 70s.

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

a fast moving shortwave is forecast to track from georgia to ern
north carolina Thursday-Friday am. 22 12z GFS has 999mb sfc
low pressure centered over SE va at 12z Friday with around 1 inch of
qpf over much of the cwa. The most recent 12z ECMWF has a much weaker
low pressure system centered around 150 miles to the southeast
with less than a quarter inch of QPF confined to SE va NE nc.

Kept pops between 25-35% with the highest values in the
southeastern CWA given the differences between the guidance.

Highs in the upper 60s on the ERN shore low 70s elsewhere thu-fri.

A more potent mid-level shortwave is still forecast to track over
the northeastern us Friday into the weekend. This will set the stage
for another chance of rain late Friday-Saturday as a cold front
passes through the region. Once again, there are differences between
the guidance regarding the strength and timing of the storm system.

Therefore, have carried slight chc chance pops from Friday
through 00z Saturday. Highs in the mid-upper 60s Saturday
warming to around 70 on Sunday. Lows in the mid 40s to around 50
next weekend.

Aviation 08z Monday through Friday
As of 1 am edt Monday...

vfr through the 06z TAF period with bkn to ovc high and mid
level cloudiness ahead of the system apprchg from the sw. Se
winds AOB 5 kt this morning increase to 10-15 kt this aftn.

Cloud deck will eventually lower late this afternoon and evening
as rain approaches from the sw. Limited any mention of
-ra to kecg which has the best chance of pcpn before 06z.

Outlook:
expect conditions to deteriorate from SW to NE late tonight as
a large area of rain approaches the cwa. This will result in
flight restrictions throughout the day Tuesday at all terminals.

Restrictions will likely last through ~12z Wed before
conditions slowly improve during the day.

East winds increase to between 15-20 kt (gusts to ~25 kt) at
orf phf sby ecg during Tue and last through 00z wed. Slightly
lower winds (e at 10-15 kt) expected at ric during this
timeframe. Winds decrease after 00z Wed and turn to the SW by
wed afternoon.

Marine
As of 400 am edt Monday...

high pressure centered off the DELMARVA will drift offshore
today resulting in a continued SE flow of 5-15 kt. Waves seas
will persist between 1- 2 ft for most of today. Seas and waves
will likely build some late this afternoon to a solid 2 ft
across the lower bay and up to 3 ft over the coastal waters
south of CAPE charles as winds increase to 15 kt late this
afternoon.

Winds and waves increase significantly overnight tonight into
tue and scas are already in effect for this period. Low
pressure over tennessee will slowly push east with a secondary
low developing along the carolina coast Tuesday. This will
result in increasing onshore flow from the se. Winds increase
quickly to 15-25kt mid morning Tuesday increasing more through
the afternoon. Rain will limit deep mixing which should help to
limit winds to 30 kt or less, however, during the period of
strongest pressure falls late Tue afternoon into Tue evening
some winds gusts to 35 kt are possible across the lower bay and
coastal waters from CAPE charles south. Seas and waves will
build quickly in the onshore flow with seas 5-9 ft off the
coast and 4-6 ft waves in the mouth of the bay (2-4ft elsewhere
in the bay).

Broad low pressure lifts north of the region during Wednesday
with ssw winds 5-15kt becoming NW in the wake of the low wed
night into thurs morning. Seas over the coastal waters may
remain elevated (greater than 5 ft) through wed. After a brief
lull midweek the next low pressure system then impacts the
region Friday Saturday.

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.
