Synopsis
High pressure builds in from the northwest tonight, and settles
immediately off the coast on Wednesday. This area of high
pressure then shifts off the coast later in the week as low
pressure passes by north of the region.

Near term until 6 am Wednesday morning
As of 735 pm edt Tuesday...

mainly skc (sct-bkn ac-ci) and cooler overnight W lows 50-55f
inland (u40s possible in a few of the colder outlying areas) to
the m-u50s along the coast in SE va NE nc. NE winds AOB 10 mph.

Short term 6 am Wednesday morning through Friday
As of 330 pm edt Tuesday...

mostly sunny Wednesday (becoming partly sunny W of i-95 in the
aftn). High temperatures ranging from the lower 70s along the
coast (upper 60s around 70f md atlantic coast), to around 80f
well inland. Remaining comfortable with dew pts in the upper 40s
e to lower- mid 50s w.

Upper level ridge axis shifts E off the coast Wed night, as an
upper low over the northern plains moves E into the great lakes.

This will allow the flow aloft to change from the SW to more of
a westerly direction by Thu morning, and to the the wnw by thu
aftn. As the gradient tightens up, the h7 to h5 winds will
increase to around 40 kt over the northern 1 2 of the area to
30-35 kt over the southern zones by late Thu aftn and evening.

In the low levels, the flow will be from the SW on Thu as sfc
high pressure shifts well offshore and low pressure moves into
the central eastern great lakes. All of this will bring a significant
change to the airmass by thu. Wed night will be mostly clear
with some increasing clouds overnight. Temperatures will fall
quickly in the evening before becoming nearly steady overnight
with lows in the mid-upper 50s E to the lower 60s w. As for
precip chances into Thu morning, the 21 12z GFS remains most
aggressive with showers tstms spreading into the region from
12-18z, while the NAM and ECMWF are generally are drier through
much of the day with the potential for some isolated scattered
convection more probable during the late aftn and evening. Have
leaned more towards the nam ECMWF scenario but did maintain
~20% pop during a portion of the morning given the uncertainty.

Highs on Thu will range from 85-90 f over most of the area
(potentially into lower 90s if it stays mostly sunny through
most of the day per the ecmwf). SPC has the far N NE in a
marginal risk for severe (primarily for straight line winds but
some large hail will also be possible). Will have ~30% chance
pops NW late Thu aftn, shifting to the NE zones Thu evening,
with ~20% pops most other places. The upper level ridge then
builds back N and amplifies a bit for fri. Have kept it dry for
fri with highs rising into the lower 90s W of the bay and in the
80s closer to the coast.

Long term Friday night through Tuesday
As of 250 pm edt Tuesday...

summerlike temperatures remaining above normal through the
extended forecast period as hi pres aloft remains centered ssw
of the fa INVOF central gulf states. Meanwhile... An anomalous
deep trough aloft will continue to largely remain out over the
wrn conus. Sfc warm front lifts N through the fa Fri night into
sat then W W flow aloft through the mid-atlantic ne
conus... That front will become hung up just N of the fa into
early next week. While isold convection possible both sat-sun
afternoons... Higher pops will be Mon afternoon as the trough
aloft sharpens through new england and a sfc cold front pushes
across the local area. Drying out cooling off tue.

Lows Fri night in the l-m60s N to the m-u60s se. Highs Sat in
the l-m80s E to the l90s w. Lows Sat night in the u60s-around
70f. Highs Sun in the 80s at the coast... L-m90s elsewhere. Lows
sun night in the u60s-around 70f. Highs Mon in the 80s E to the
l90s inland. Highs Tue from the u70s-l80s E to the m80s inland.

Aviation 00z Wednesday through Sunday
As of 735 pm edt Tuesday...

vfr conditions expected through the 00z 22 TAF forecast period
w sfc hi pres in control. Nne winds tonight become se
wed... Remaining blo 15 kt. There is a 20-30% chc for shras tstms
thu aftn evening as a trough slides across the fa in NW flow
aloft. Dry conditions are expected Fri into the weekend as weak
hi pres returns.

Marine
As of 330 pm edt Tuesday...

high pressure will continue to build in from the north through
tonight. N winds 10-15 kt into this evening will become NE 5-10 kt
overnight. High pressure will center itself off DELMARVA on
Wednesday with ese winds 5-15 kt. High pressure then moves offshore
Wednesday night and Thursday with winds becoming S 10-15 kt. Winds
become SE late Thursday, increasing to 15-20 kt offshore for a time
Thursday evening in advance of the next cold front. Winds then turn
nnw behind the front on Friday, but still remain below SCA levels.

For this weekend, SE winds around 10 kt expected on Saturday and ssw
winds 10-15 kt on Sunday. Waves 1-2 ft; seas 2-4 ft through the
period.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
