Synopsis
High pressure becomes centered off the mid atlantic coast
through Tuesday. A cold front crosses the area late Wednesday,
with strong high pressure building north of the area from Thursday
into the upcoming weekend.

Near term through tonight
Latest analysis indicating a broad area of ~1022 mb sfc high
pressure centered over the local area. Main concern early this
morning is with patchy fog, but for the most part dense fog is
not likely (locally the typical rural low lying spots can expect
1 2sm at times through 12z). Temperatures will range from the
mid 60s to lower 70s.

Otherwise for today, expect partly cloudy variably cloudy skies
with decent eclipse viewing expected for the most part this aftn
(but it will not be as sunny as yesterday). With some weak
upper level shortwave energy currently over in oh moving east
through the day, should see enough of a trigger for sct
convection to develop across the mts then drift e-se across the
northern most zones of the fa by around 18z. Will carry chc
pops to 30-40% mainly north of ric, with 20% into metro ric and
dry across the south. Highs upr 80s- lwr 90s except mid 80s at
the beaches. Hourly temperature forecast has temperatures
falling a few degrees during the eclipse (18 19z), then rising
again through 21z. Becoming mostly clear this evening except
partly cloudy NE where a 20-30% pop will be maintained.

Warm humid with lows mainly 70-75 f tonight.

Short term Tuesday through Wednesday
Hot mainly dry tues ahead of the approaching cold front. 85-90 f
along the coast, 90-95 f west of the bay. Dry most of tues
night except increasing moisture could lead to a few shwrs by
daybreak across NRN most zones. Warm with most areas having lows
only in the mid 70s.

Frontal boundary a bit slower to traverse the fa wed. This combined
with a weak wave progged to move east along it will spread widespread
moisture and support likely pops in the afternoon, but probably
not much in the morning (especially over the se). Another round
of mdt to hvy downpours possible ahead and along the fropa.

Highs mid 80s NW to around 90 f south.

Long term Wednesday night through Sunday
A cold front gradually drops through the area Wednesday
night into Thursday morning. Modest ascent accompanies the front
within the rrq of a ~110kt jet over new england along with pw
values to around 2.0" (around +1 st dev). The highest pops by
wed evening look to focus across SRN va NE nc where 70% will be
maintained, tapered to ~30% across the NW where drier air arrive
first. Pops across SE portions gradually diminish to 20-40% by
Thursday aftn. Thunder will be maintained into Wednesday
evening, with showers thereafter as stable NE flow prevails in
the wake of the front. Drier air gradually filters in from the
nw late Wednesday night into Thursday with partial clearing
across the NRN tier counties. Lows Wednesday night range from
the mid 60s NW to the low 70s se, followed by highs Thursday in
the upper 70s to low 80s. ~1025mb (+1 st dev) high pressure
builds from the great lakes across the saint lawrence valley and
into new england Thursday nigh through Sunday. This will result
in persistent onshore flow, which combined with a drier airmass
will result in a series of pleasant days with highs in the
upper 70s at the coast to low 80s inland, with lows in the upper
50s to low 60s inland, and mid upper 60s along the coastlines.

Aviation 08z Monday through Friday
Patchy fog low stratus across the region early this morning,
though for the most part only marginal MVFR vsbys have affected
taf sites. Did include some tempo mention of ifr vsbys of 1-2sm
in all tafs except for orf at some point, mainly focused on
09-12z. Any morning fog low cloud burns off 12-13z withVFR
conditions to follow. Isolated tstms in the aftn evening
possible at ric sby but still mainly dry. Continued mainly dry
and probably will see a little less in the way of fog low cloud
tue morning as southerly flow becomes a little stronger. The
next cold front approaches the region wed, and flight
restrictions will be possible wed, mainly in the aftn and
through Wed night in showers tstms. Some showers may linger
across SE terminals into Thu morning, but otherwise improving
conditions except with a breezy NE flow near the coast Thu fri.

Marine
Early this morning, sfc high pressure was cntrd over the area.

The high will move off the coast and out to sea today through
tue, and a cold front will approach the waters Tue night into
wed morning. The front will then cross the area Wed wed night
and will push well SE of the area during thu, with high
pressure building back into the region for the remainder of the
forecast period. Expect SE or S winds around 10 kt or less
during today, as high pressure moves offshore. Winds increase
and become ssw ahead of the approaching cold front Tue through
tue night. Winds speeds may approach 15 to 20 kt over the ches
bay and ocean with seas building to 3 to 4 ft, potentially up to
5 ft north 20nm out, and waves building to 2 to 3 ft. A small
craft advisory may be needed for the chesapeake bay and NRN two
coastal zns Tue night. Winds shift to the N NE behind the front
late Wed through Thu around 10 to 15 kt.

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.
