Synopsis
High pressure settles offshore into tonight. This area of high
pressure then shifts well off the southeast coast Thursday into
Thursday night as low pressure passes north of the region.

Near term until 6 am this morning
As of 910 pm edt Wednesday...

winds have become SE this evening... And will become more s
overnight as sfc hi pres near the coast (now) shifts farther
offshore (after midnight). An area of bkn-ovc sc (cigs roughly
3-5kft) moving only very slow progress nne through SW portions
of the fa (in va). Hi res guidance does suggest some of that
moisture continues to spread ene overnight resulting in partly
cloudy conditions... ESP inland. Not quite a cool overnight as
dew points have nudged up a bit as winds have shifted to se
(then eventually s). Lows in the m-u50s... Except around 60f
across parts of the piedmont SW of ric and the l50s inland on
the lower md ERN shore.

Short term 6 am this morning through Saturday night
As of 330 pm edt Wednesday...

the mid upper level ridge axis will push offshore Thursday
morning as a shortwave trough tracks through ERN great lakes.

Meanwhile, the low-level flow will become sw, which will allow
for slow moistening of the low-level airmass. Warmer high
temperatures in the mid 80s to around 90f are expected across
our area, with low 80s for much of the ERN shore and coastal se
va NE nc, and upper 70s at the immediate atlantic coast of the
ern shore.

We are continuing to monitor the potential for some thunderstorms
thu aftn and evening. SPC has added a small area of slight risk
over the far northern quarter of the area (ric to sby and
north). Convective threat for Thursday remains conditional; and
is dependent upon the development of an MCS upstream from kstl
to ksdf late tonight early thu. Should this feature develop as
modeled by cams, the MCS would push across from WV pa into S pa
and nj Thursday aftn and evening. This is expected to trigger
convection N of the region in a zone of 40-50kt 500mb flow and
35-45kt 700mb flow. Must note that this shortwave will dampen
upper ridging to a degree... With resultant quasi-downslope flow
serving to lower areal coverage of tstms over the local area.

That said, there is the potential for isolated to widely sct
outflow- driven tstms from this feature, which could move off
the higher terrain into the NW piedmont after 20z 4pm later
Thursday aftn, and potentially pushing across the NRN neck and
md ERN shore by mid to late Thursday evening. Obviously, a lot
has to go "right" for this convection to develop as modeled, and
for that reason... We will continue to cap pops at 30%-40% for now,
highest in the slight risk area from the NW piedmont counties to
the md ERN shore, bordered by 20% for much of the area, and
less than 15% far SRN va NE nc. The potential for some stronger
storms does exist, given cooling drying aloft... With large hail
and damaging winds the primary threats in any convection that
can make its way toward the area tomorrow evening.

Heat then builds for Friday through the weekend. Good model
agreement continues with respect to building strong upper ridge
back to the north Fri sat, before the ridge flattens late in
the holiday weekend courtesy of northern stream shortwave
sliding across the upper great lakes and SE canada. Increasingly
hot, though remaining mainly dry. Some isolated (mainly
diurnally driven) convection possible along lee troughing to the
west Sun afternoon. Highs in the mid 80s to near 90 on sat, 80s
along the coast, l-m 90s inland on Sunday. Early morning lows
60s to near 70.

Long term Sunday through Wednesday
As of 250 pm edt Wednesday...

summerlike temperatures remaining above normal through the extended
forecast period. An upper level anticyclone remains centered along
the gulf coast early next week, putting our region in w-nw flow
aloft. Meanwhile, an anomalous deep trough aloft will continue
to largely remain out over the WRN conus. A weak frontal
boundary crosses the area Sun evening-sun night, but only
isolated tstms are expected (mainly N ne). Isolated-scattered
aftn evening tstms are possible on mon, but the chance of this
is only ~20%. Drying out from tue-wed as upper ridging amplifies
over the us east coast as the aforementioned deep trough aloft
ejects out into the NRN plains.

Lows Sun night in the u60s-around 70f. Highs Mon in the 80s over the
lower ERN shore to the low 90s inland. Highs Tue from the low 80s
over the ERN shore to near 90f inland. Forecast highs on Wed are in
the low 90s in most areas, but there is the potential for it to be
even warmer.

Aviation 06z Thursday through Monday
As of 155 am edt Thursday...

high pressure is centered off the mid-atlantic coast as of 06z.

The wind is light (aob 5kt) out of the SE under sct mid and high
clouds. An area of bkn-ovc CIGS ~4-5kft over the piedmont will
push ewd through the morning, but will generally lift to
8-10kft, before scattering later this morning. Surface high
pressure will push farther offshore today with the wind becoming
sw, and increasing to 8-12kt with gusts of 15-20kt by this aftn.

Sct CU are expected to develop by this aftn, with a 20-30% chc
of showers tstms (primarily from ric-sby and n) after 20z and
continuing through 04z Friday as a trough pushes across the
region in NW flow aloft. Tstms could produce locally stronger
wind gusts along with reduced vsby in brief heavy rain.

Mainly dry conditions are expected Friday through the weekend
and into memorial day as weak high pressure prevails over the
region. There is a low probability of showers tstms Sunday
night along and N of a line from ric-sby.

Marine
As of 345 pm edt Wednesday...

high pressure will move off shore tonight. Winds overnight will
be 5-10 kt and seas will come down to around 1 ft in the bay
and 2-3 ft in the atlantic. As a cold front approaches from the
north, southwesterly winds will increase tomorrow afternoon. Not
going with any SCA for tomorrow afternoon because conditions
will be marginal. Gust may exceed 25 kt for a short period of
time and waves will touch 5 ft off the eastern shore's atlantic
coast(mostly far offshore edge of our zones). Farther south in
the atlantic, winds will between 15-20 kt with waves 3-4 ft. In
the chesepeake bay and rivers, winds Thursday afternoon will be
10-15 kt and waves will be around 1-2 ft.

Behind the cold front on Friday, high pressure will build back
into the area for the holiday weekend. Looks like winds and seas
will stay below SCA criteria through Monday.
