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 Thursday morning
As of 330 pm edt Wednesday...

winds will become sse though this evening, as sfc high over the
region nudges offshore, and remains near the coast through
early Thursday. Becoming mostly clear with an increase in mid
and high clouds western sections late. Small chance of some
very light rain sprinkles over the i-85 corridor towards morning
in association with some very shallow overrunning moisture.

Chances of measuring pcpn are very low over this area through
12z, so have pulled out rain chances and just showed increasing
clouds in grids. One more cool, comfortable night... As temperatures
fall quickly (especially coastal sections) then stabilize
overnight, with early morning low temperatures to range from the
mid 50s over the interior ERN shore and interior SE va NE nc,
to the upper 50s around 60f elsewhere.

Short term 6 am Thursday 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. Weak frontal boundary crosses
the area Sun evening-sun night, but only isolated tstms are expected
attm (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 20z Wednesday through Monday
As of 145 pm edt Wednesday...

high pressure centered N of the region will slide offshore
through this evening. Light nne winds become sse 5-10kt at
ric sby by late this aftn, and ese 5-10kt and phf orf ecg under
a mostly sunny sky (sct-bkn high clouds over eastern shore
around ksby terminal). By tonight, a light SE wind will become
sw under a mostly clear sky.

Outlook: there is a 20-30% chc of showers tstms (primarily ric-
sby and points n) after 20z 4pm later Thursday aftn evening as
a trough slides across the region in NW flow aloft. Mainly dry
conditions are expected Friday through the weekend as weak high
pressure prevails over the region.

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.
