Synopsis
High pressure remains centered off the southeast coast through
Monday. A cold front crosses the region Tuesday morning.

Near term through tonight
Weak upper level trough slides across the SE states and off the
coast today as ridging aloft dominates from the tn-oh valleys
to the mid-atlantic states. Very lo prob for patchy fg early
this morning... Otherwise sct-bkn clouds (averaging out mostly
sunny). Winds vrb-ssw AOB 10 kt. Highs in the l-m50s on the ern
shore to the u50-l60s elsewhere.

Short term Monday through Tuesday
Sfc hi pres remains off the E coast through Mon while lo pres
tracks from the central plains to the WRN lakes. Ssw flow will
keep mild wx over the region W partly cloudy conditions. Lows
tonight in the m-u30s. Highs Mon 55-60f near the bay ocean and
on the ERN shore to 60-65f for most other locations.

Rain chances increase quickly after midnight Mon night through
tue morning as lo pres tracks through the lakes region... Pushing
its associated cold front across the local area. Models now in
general agreement wrt timing that front through the fa. Keeping
chc to likely pops for most of the area during 06z-17z 23 (tue)
then pcpn moving out of the entire area by 00z 24 (wed). Will
also keep hidden very lo pops for isold tstms. Lows Mon night
from the u40s-l50s. Highs Tue from 60-65f N and on the ERN shore
to the u60s-l70s s.

Long term Tuesday night through Saturday
Models are in very good agreement in the extended range from 00z
wed through Saturday with the long wave trough pulling out of
the northeastern us Wed and Thursday with a shortwave ridge
building in for Friday and Saturday. At the surface, the period
begins with NW flow as the surface low over deepens over the
nern us. The surface low will lift NE into the canadian
maritimes by Wed evening. With the NW flow, expect the clouds
to clear tues night into Wednesday but with the cold advection,
temperatures will be cooler into the upper 40s to lower 50s.

Another shortwave will move through the eastern trough on
Tuesday and will bring a reinforcing cold front to the area.

This may knock temperatures down a couple more degrees on
Thursday, but with little moisture expect to see just a few
clouds across the northern portion of the cwa.

High pressure will build into the area on Thursday night into
Friday. The high will remain in place through Saturday before
slowly sliding off the coast by late Saturday with SW flow
returning. This will allow for good radiation cooling both thurs
and Fri night with temps in the u 20s to l30s thurs night and
low to mid 30s Friday night. For Friday should see lots of sun
with highs around the mid 40s over lower md and m50s in
southern va. On Saturday with the return flow the models are
indicating return moisture getting in and some showers possible
late day, but at this point, not ready to introduce pops so have
gone with just slight chance values in the 15 to 20% range.

High should continue to modify into the 50s to around 60f.

Aviation 12z Sunday through Thursday
Vfr conditions will continue through the 12z TAF period as sfc
hi pres continues to dominate. Winds will be vrb-ssw AOB 10 kt.

Sfc hi pres settles off the SE coast through Mon W mainly and dry
conditions continuing. The next chance for widespread
precipitation and flight restrictions comes late Mon night into
tue night with a passing cold front. High pres returns later
tue.

Marine
High pressure, centered over and just off the southeast us coast,
will remain in control of the weather thru Monday with winds 10 kt
or less and generally benign boating conditions. By Monday night,
winds will begin to increase again out of the south as a deepening
low over the great lakes pushes its associated cold front toward the
region. Wind will increase to 15 to 25 kt from the s-sw prior to
daybreak tues, continuing thru midday, with seas on the coastal
waters building to 4-6 ft; waves 3-4 ft on the bay. Scas will likely
be needed. Once the front clears the area tues afternoon, winds will
shift to the west 10-15 kt tues night Wed and then northwest on
Thursday. Waves seas subside to 1-3 ft.

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.
