Synopsis
A weak frontal boundary over the area lifts back to the north
tonight into Monday. A cold front approaches from the west
Monday night and crosses the region late Tuesday through
Tuesday night. High pressure builds in from the north on
Wednesday.

Near term /through Monday/
The current surface analysis indicates a sfc boundary extending
from the central piedmont to SE va. This boundary progressed
ne-sw through the late aftn/early evening hours and has now
become stationary. Cool and cloudy over the nrn/ne zones
(temperatures mainly in the mid 40s to low 50s), with readings
in the mid 50s roughly along the i-64 corridor, and low/mid 60s
s of the boundary across far s-central va and interior NE nc.

Fog has pushed onshore, and is thickest along the atlantic coast
of the ERN shore with vsby of 1/2-1sm. Most guidance indicates
the front begins to retreat to the NE by 06z, and then lifts n
of the area after 08z. Therefore, expect fog to
retreat/dissipate as well. Sct showers across the piedmont
associated with a dampening shortwave trough should dissipate
between 04-06z. Lows tonight range from the mid/upper 40s across
the ERN shore to the low/mid 50s elsewhere. Mainly dry and
partly cloudy conditions are expected across far SE va and ne
nc.

Initial system lifts into/through new england mon... Leaving fa
w/ continued mild/warm conditions as hi pres (sfc-aloft) remains
invof SE CONUS coast. Genly mostly cloudy Mon morning, becoming
partly sunny by aftn. All zones will be back in the warm sector
mon, even the eastern shore so aside from locally cooler
readings at the immediate coast, most areas will rise into the
mid-upper 70s. Not much forcing for widespread precip, but will
carry 20% pops for aftn showers/tstms inland given some
instability by aftn.

Short term /Monday night through Wednesday/
Upper level ridging begins to break down Mon night, as the front
approaches from the W and will carry chc pops west of i-95 after
midnight/20% or less e. Warm with lows mainly 55-60 f. Upper
level trough pushes into the area Tue as a sfc cold front passes
by late. Continued warm w/ highs well into the 70s to near 80f
there will be a higher chance for showers and aftn tstms. Will
continue with 40-50% pops most areas, with a small area of 60%
pops across the n. There will be some potential for a few
stronger storms Tue aftn/evening as speed and directional
increases and sfc dew pts will be near 60 f, but overall not
looking like widespread severe wx. Drying late Tue night with
lows mainly 50-55 f, with mostly sunny conditions wed, somewhat
cooler but still a little above avg with highs 60-65 near the
coast and in the upper 60s to lower 70s well inland.

Long term /Wednesday night through Sunday/
Dry wx expected for Wed night thru thu, as high pressure builds
down over the area to along the east coast. Decent chc for
showers and possible tstms later Thu night into early sat
morning, as low pressure and another associated cold front
approaches and moves acrs the region. Dry wx and high pressure
returns for Sat aftn thru sun.

Highs in the mid 50s to lower 60s thu, in the upper 50s to mid
60s fri, and in the 60s to near 70 Sat and sun. Lows in the
upper 30s to mid 40s Wed night, in the lower to mid 40s thu
night, in the mid 40s to lower 50s Fri night, and in the 40s sat
night.

Aviation /02z Monday through Friday/
MostlyVFR conditions across the region accept on the eastern
shore where onshore flow continues to produce ifr fog and cloud
ceilings. Ifr conditions expected to continue at sby until
3-4:00 in the morning then fog and ceilings expected to improve
as the wind shifts from east to south... Then southwest.

Isolated showers possible tonight with ric probably having the
best chance to get some rain. Some MVFR ceilings may also move
into ric during the early morning hours as low clouds move into
central va from the south. Unsettled wx conditions will persist
across the region through mid-week. Scattered showers becoming
increasingly likely by tue/tue night. Periods of reduced
aviation conditions will be possible during times of
precipitation. Dry/vfr Wed as winds shift to the n.

Marine
Put up a headline for dense fog over the coastal waters from
fenwick is to parramore is until 4 am. A frontal boundary was
laying acrs NRN portions of the area and off the SRN delmarva
coast. Also, low pressure was over SRN lake michigan. That low
will lift NE acrs the great lakes tonight into Mon morning,
pulling the frontal boundary N of the marine waters. As a
result, NE thru SE winds 15 kt or less this evening will become
s 5 to 15 kt later tonight into Mon morning. Low pressure and
its associated cold front will then track fm the cntrl/srn
plains ene and acrs the local area Tue aftn into early wed
morning. Expect SW or S winds arnd 15 kt or less Mon thru Tue in
advance of this system. Then, as the low and cold front move
out to sea late Tue night thru Wed morning, winds will turn to
the NW then N 15 kt or less. High pressure will build in fm the
n for Wed night and thu, with NE winds 15 kt or less... Become e
by late thu. Seas 2-4 ft; waves 1-3 ft thru the period.

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.
