Synopsis
Low pressure will move up the coast Wednesday into Thursday
spreading rain across the region. High pressure will bring sunny
and warm weather through the weekend. Low pressure system will
spread clouds and rain into the carolinas Monday into Tuesday.

Near term through Wednesday night
As of 300 pm Tuesday... Tricky forecast on tap for the near term
period. First off, with temps mainly just getting down into the
upr 30s tonight (mid 30s though in coldest spots), not
expecting much in the way of frost with ~5 kt wind and dewpoints
down in the upr 20s. Exception may be over far western areas
where patchy frost is possible. Surface high pressure north of
the area this aftn slides offshore tonight. Meanwhile, coastal
low pressure gradually develops just offshore through Wednesday
as a mid-level shortwave trough approaches from the west. Result
will be increasing chances of rain from east to west through
the day Wednesday, continuing into Wednesday night, in response
to increasing low-level convergence and isentropic upglide. Pops
increased to 60-70% for eastern areas where the rain may be
moderate to possibly heavy at times. As for temps, expect only
highs in the 50s Wednesday due to NE flow and a cloudy sky. Lows
temps Wednesday night mainly 40-45. &&

Short term Thursday through Thursday night
As of 300 pm Tuesday... Surface low will lift off to the
north as potent shortwave crosses the carolinas on Thursday. Any
lingering pcp from sfc low will move out of the area Thursday
morning. Dry air will wrap around the back end with some
clearing through the day, but mid to upper shortwave will ride
through later in the day with mainly clouds, but may see some
light pcp mainly to the north of local area over nc. Deep nw
flow will develop through thurs night on back end of shortwave
moving out of area. This will give a little punch of caa.

Overall, expect some clouds mixing with Sun and low end pcp chc
on thurs, but weather improving through thurs night. Temps
should be near seasonable through the period with overnight lows
in the 40s and

Long term Friday through Tuesday
As of 300 pm Tuesday... High pressure will build in slowly from
the west and will migrate eastward through the weekend at the
same time as mid to upper ridge builds over the area. Overall,
expect a dry weekend with plenty of sunshine and warming temps.

The dry air mass in place will allow for some large diurnal
temp swings with afternoon highs just above normal and overnight
lows just below.

The center of the high will shift off shore Sunday night into
Monday. This will produce a southerly return flow which will
help to increase the temps and moisture, leading to some clouds
mixing with the sunshine on Monday, but temps warming into the
70s. By Mon night into tues, mid to upper trough will dig down
over the southeast. This will help to deepen sfc low as it
tracks east toward the coast while at the same time, a cold
front will drop down from the north. This will help to spread
clouds and pcp into the carolinas Mon night into midweek. Cooler
air behind the front will drop temps quite a bit for tues.

Aviation 18z Tuesday through Sunday
As of 18z... .Vfr conditions prevail through tomorrow morning.

Scattered cirrus from the southwest, more abundant along the coast,
will continue to move out of the area. Meanwhile, low cloud deck
will be moving in late tonight. Expect ceilings to lower to MVFR at
coastal sites sometime tomorrow morning, and inland terminals either
at end of TAF period or soon after. Rain chances also increase from
the east in the last few hours of the TAF at all terminals except
flo. Northeast winds to continue through tomorrow, weakening some
this evening before becoming gusty again overnight at coastal sites
and tomorrow morning at inland terminals.

Extended outlook... Likely MVFR late Wednesday through Thursday
with storm system.VFR returns Friday into weekend.

Marine
As of 3 pm Tuesday... Small craft advisory continues over all waters
for a prolonged period of 15-25 kt NE winds with gusts up to 30 kt.

This as strong high pressure anchors off to the NE and surface low
pressure develops just offshore late Wednesday. Winds may diminish
as the center of low pressure moves directly over the local waters
Wednesday night, but continued high seas may warrant an extension to
the current small craft advisory end time (midnight Wednesday
night).

Offshore flow will develop as high pressure begins to
build in behind departing low on Thursday. The diminishing off
shore flow will allow seas to subside from advisory levels thurs
morning down to 3 to 5 ft by end of the day. Gradient will
remain a bit tight, though, as high pressure builds down and
low strengthens off the coast of new england into fri. Therefore
winds may increase again thurs night into early fri, with seas
slower to drop, especially in the outer waters fri.

By the weekend, winds will lighten as high pressure migrates
slowly eastward reaching overhead by Sunday. This will produce
improving marine conditions over the weekend with seas 2 to 4 ft
on Sat and down less than 2 ft on Sunday.

Nc... None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
