Synopsis
A cold front will linger just offshore and south of the region
through tonight. High pressure builds into the region late
tonight through early next week. The next cold front will impact
the region on Wednesday.

Near term until 6 am Sunday morning
Isold convection INVOF coastal NE nc has waned... But watching
tstms moving across NRN va associated W secondary cold (more
like a dew point) front settling se. Near term models keep
convection N of the fa while slowly weakening as that boundary
pushes S overnight. Otherwise... Mainly skc W light winds. A
drop in dew points expected by late at night. Kept patchy fog
out of the forecast... Though would not be surprised to have
some... ESP where recent rainfall has been excessive (i.E., on
the ERN shore). Lows in the u60 NW to the l-m70s S and e.

Short term 6 am Sunday morning through Tuesday
For Sunday... High pressure builds back into the region for Sunday
allowing for dry conditions and mostly sunny skies for much of the
region. Highs will range from the mid to upper 80s along the coast
to around 90 degrees inland.

Sunday night begins with high pressure centered just north of
the area across md and pa. This will provide a quiet evening
with generally light E to SE flow. Will see a little return of
atlantic moisture but overall expect dry weather mostly clear
conditions. Temperatures should cool a little more than in
recent days with low in the upper 60s to the lower 70s.

The area of high pressure slides off the coast on Monday and the
flow turns SE to s, which will allow some additional moisture to
return to the area. The orographic lift will allow some
convection to form along the blue ridge and appalachian
mountains. Some of this convection could slide newd off the
higher terrain and impact portions of the piedmont counties
later on Monday afternoon and evening so have continued the
slight chance pops. But most areas should be dry due to a lack
of lift and little mid level moisture. Temperatures should begin
to climb with most areas getting back up into the lower 90s.

Monday night into Tuesday expect mainly dry weather as well, but
the humidity will still be there as the southerly flow
continues. Lows during the overnight hours should be in the low
to mid 70s and the highs on Tuesday should be a little warmer
again with highs still in the low to mid 90s. The southeastern
portion of the CWA would have the best chance for an isolated
shower as some atlantic moisture lifts newd into NE nc and the
va tidewater.

Long term Tuesday night through Saturday
Stacked high pressure resides off the southeast coast as a
pre-frontal trough develops ahead of an approaching cold front
and in the lee of the mts Tue night. Overall, Tue night should
be dry with isolated showers storms possibly sneaking into
the far WRN piedmont and or md lower eastern shore INVOF the
developing trough. Warm and humid overnight with lows in the
low-mid 70s. The cold front tracks through the area on wed...

exiting the coast by Thu morning. Thunderstorms expected to
become more organized as the front provides better focus for
lift development. Lingering showers storms possible
far SE va NE nc on thu, although they should taper off from
nw to SE as the front moves farther southeast and away from
the area. Otherwise, cool canadian high pressure builds across
the midwest into the ERN great lakes thu-sat with dry
conditions anticipated during this timeframe.

Highs Wed generally upper 80s to lower 90s (mid 80s beaches).

Highs thu-sat lower 80s (mid 70s beaches). Lows Wed night
mid-upper 60s NW to 70-74f se. Lows Thu Fri nights around
60f NW to around 70f se.

Aviation 02z Sunday through Thursday
Isold tstms INVOF kecg continuing weaken... OtherwiseVFR
conditions over the region. Potential patchy occasional MVFR
fog... Mainly after 06z 20... At the typical fog-prone locations
(sby ecg phf). All fog should quickly dissipate after sunrise.

After that...VFR conditions through Monday as sfc hi pres
builds back into the region. There will once again be the
potential for some patchy fog early on Monday morning. The next
cold front approaches the region late Tue and into wed.

Sub-vfr conditions and showers thunderstorms will be possible

Marine
Benign conditions through Sun with light variable winds
aob 10kt. Winds become more onshore Sun night into mon
(remaining AOB 10kt) as a front near the mid atlantic coast
washes out weakens. Seas average 2ft; waves 1-2ft. South winds
mon night-tue night with stacked high pressure off the
southeast coast and a thermal trough developing in the lee of
the mts Tue night. A surge in winds is anticipated Tue night
into Wed morning ahead of an approaching cold front. Speeds
could reach 15-20kt bay ocean with seas building to 3-4ft
north and 2-3ft south; waves building to 2-3ft. SCA flags may
be possible for these areas in this timeframe. The next cold
front is expected to cross the region during Wed and exit the
coast by Thu morning. Winds n-ne AOB 15kt behind front wed

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.
