Synopsis
A cold front exits the coast overnight. High pressure returns
Tuesday and Wednesday, then shifts off the coast late in the
week.

Near term until 6 am this morning
As of 940 pm edt Monday...

last of the convection tracking through SE portion of the fa
attm... Then shifts off the coast overnight. A cold front remains
just of the fa and that front reaches the coast by late tonight.

Sw winds 5-15 mph shift to nnw as cool dry air advection takes
place. It will remain fairly breezy in the wake of the front
along the bay and coast (20 mph or so). Lows from the u50s N and
nw to the u60s se.

Short term 6 am this morning through Thursday
As of 345 pm edt Monday...

tues Wed will be much cooler and drier (even slightly below avg
for temperatures in some areas). This as high pressure centered
over the great lakes gradually builds SE into the local area by
tue aftn through Tue night, then becomes centered from the
eastern great lakes to the va coast on wed. Dry with mostly
sunny skies both Tue Wed and mostly clear Tue night. Highs
Tuesday mostly in the 70s except near lower 80s possible south
central va to interior NE nc. Dew pts will fall into the 40s n
and the lower-mid 50s s. Lows Tue night in the 50s except some
upr 40s psbl in those normally cooler locations over the
piedmont. Highs Wed upper 70s to lower 80s inland, and lower to
mid 70s near the bay and ocean.

The high shifts east Wed night and thurs allowing the start of
the next warmup. Models continue to show a NW flow upr level
flow pattern setting up that could allow for another round of
upstream convective to dive se. GFS remains most aggressive with
this, while the nam ECMWF are genly drier. Timing can be a
problem this far out so kept sonly ~20% pops in the forecast fro
late Wed night into thu. Light chc pops in for now with plenty
of time to update as necessary. Lows Wed night upr 50s- lwr 60s.

Highs thurs mid- upr 80s, upper 70s- lwr 80s near the water.

Long term Thursday night through Monday
As of 330 pm edt Monday...

a few tstms are possible (highest chances ne) Thu night as a weak
disturbance in NW flow aloft tracks through the region. Otherwise,
strong upper-level ridging (and associated anticyclone) remains
centered over the southeast for much of the extended period while a
series of shortwaves track well to our N (from the upper midwest to
new england). As a result, very high confidence in above average
temperatures (and mostly dry conditions) from Fri through early next
week. A weak cold front may try to sneak into nrn ERN portions of
the CWA on Sat am, but no pcpn is expected with the fropa. The front
quickly washes out during the day on sat. Perhaps a brief
shower TSTM Sat night, but otherwise dry this weekend. Slight
chances for mainly aftn-evening showers tstms may return early next
week as the center of the anticyclone retreats slightly to the
southwest. Highs mainly in the low-mid 90s inland on Fri with mid
80s-around 90f near the coast. Still very warm on Sat with highs
ranging from the mid 80-low 90s (highest inland coolest over the
lower md ERN shore). Sunday may be the hottest day of the weekend
with highs will be in the mid 90s in most areas W upper 80s on the
lower ERN shore. Lows throughout the extended period will mainly in
the mid 60s-around 70f.

Aviation 06z Tuesday through Saturday
As of 200 am edt Tuesday...

a cold front is slowly pushing through the region as of 06z and
is primarily accompanied by sct-bkn mid-clouds ~10kft as
isolated showers have now pushed offshore. The wind will
initially shift to NW behind the front, and then turn nne 8-12kt
primarily after 12z, and continuing through the day with
occasional gusts to 15-20kt. Mostly clear sunny conditions are
expected once the front pushes offshore as high pressure builds
in from the nw. High pressure becomes centered N of the area
tonight, with a light NE wind under a clear sky.

High pressure remains over the region Wednesday, before sliding
offshore Wednesday night into Thursday. There is a 20-30% chc of
showers tstms Thursday aftn evening as a trough slides across
the area in NW flow aloft. Dry conditions are expected Friday
into Saturday as weak high pressure returns.

Marine
As of 330 pm edt Monday...

s-sw winds 10-15 knots bay and 10-20 knots ocean will continue into
this evening, before a cold front sweeps across the waters tonight.

Fairly modest pressure rises occur behind the frontal passage, with
high res guidance still showing a surge of nnw winds in the wake of
the front late tonight early Tuesday. Winds in the bay and lower
james river will generally run 15-20 knots with gusts to 25 knots.

Accordingly, scas remains in effect for these areas from late
tonight through 10 am Tuesday. Waves will briefly build to 3 ft
overnight and then subside to 1-2 ft by Tuesday afternoon. Winds
offshore will also run 15-20 knots with gusts up to 25 knots and
seas 3-4 ft in offshore flow. Winds decrease to 5-15 knots later
Tuesday into Wednesday before swinging around to the ene and then
ssw by Thursday as high pressure moves offshore and ridging aloft
builds over the southeast. There is the potential for another cold
frontal passage on Friday.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
