Synopsis
A cold front will remain stalled well to our south through
tonight. High pressure will become centered over new england
early Monday through Tuesday as low pressure is slow to lift
northeast well off the carolina coast.

Near term until 6 am Monday morning
As of 320 pm edt Sunday...

latest weather analysis reveals 1028mb surface high pressure
centered over atlantic canada and northern new england wedging
down east of the appalachians into the mid-atlantic. To the
south, sfc cold front remains well south of the region, draped
across S ga fl panhandle and extending out offshore of the
carolina coast.

Visible Sat imagery shows sct CU have developed mainly along
and north of us-460 over central and eastern va and the lower
eastern shore, with bkn-sct mid-level cloudiness closer to the
front along the va nc coast and into NE nc along the albemarle
sound, where low level moisture remains the highest. Have
allowed for some iso to widely sct showers in the grids as
modest convergence offshore of the S nj de coast nudges toward
the sby oxb area from late aftn into this evening.

Clouds briefly diminish with loss of heating this evening, but
expect re-development, W at least partial coverage of low
stratus toward morning. A few sprinkles or some patchy dz also
possible toward daybreak along the bay and over the eastern
shore. Lows in the 60s, though some mid to upper 50s again
possible inland.

Short term 6 am Monday morning through Wednesday
As of 320 pm edt Sunday...

model preference continued to follow a wpc (gfs ecmwf) blend.

Models are slowly coming into better agreement with weak sfc
low NE off the ga north fl coast late tonight, with the system
sliding slowly NE well off the carolina coast through the day on
Tuesday.

Onshore flow increases a bit tomorrow, which allows for a
greater coverage of clouds and also a bit more in the way of
isolated to widely sct showers (especially east of i-95). Sfc
high stays parked over new england, with resultant E to NE low
level onshore flow lingering over the local area. Deeper
moisture looks to stay offshore, but will see a gradual increase
in dewpts and precipitable water values through midweek. Have
maintained mostly chance pops for both Tue wed, primarily due
to the moisture overrunning the wedging high rather than the sfc
low itself (as it will be well offshore).

At this time, given a farther offshore track, weak shear and
rather ragged appearance, trends are slightly less bullish
regarding further development in the short term. That said, we
will need to continue monitoring potential further tropical
development evolution with this system through midweek. Highs
will be mainly in the upper 70s lower 80s mon, and 80-85f tue,
with lows in the 60s Sun night Mon am and mid 60s to lower 70s
mon night Tue am. Skies will be partly to mostly cloudy.

Long term Wednesday night through Sunday
As of 345 pm edt Sunday...

cold front will be moving off our coast early Thursday with sfc
high pressure building into the area. Pops were kept in (mainly
east of i-95) Thursday. Downslope flow will keep most of the
area dry through the extended forecast period. However, the
front stalls along the carolina coast, which may bring a few
showers to NE nc and va beach. Temperature won't drop too much
behind the front. High will be mainly in the low-mid 80 and lows
in the 60s inland to 70 near the ocean and bay thur-fri.

Temperatures then begin to climb once again ahead of another
cold front next weekend. Temperatures may reach the low 90s
along the i-95 corridor Saturday and Sunday. The beaches will be
slightly cooler with temperatures reaching the mid 80s. Chance
of showers and thunderstorms return for Sunday afternoon with
the font.

Aviation 20z Sunday through Friday
As of 310 pm edt Sunday...

vfr conditions at all TAF sites continue through this evening.

High pressure to the north will let CU field scatter out
somewhat through early this evening, especially to the north and
west of ric-phf line. Low level moisture lingers closer to the
coast thus skies will remain sct- bkn across the south east
(mainly orf ecg). In addition, a very low ran chance for
isolated to scattered rain showers cannot be ruled at eastern
taf sites late this afternoon and evening (mainly sby). Gusty
northeast wind of 15 to 20 knots at orf ecg continue today and
tonight, around 10 knots elsewhere. Low stratus looks to develop
after 05-07z Monday, potentially creating sub-VFR conditions
at all TAF periods for a period of time Monday morning (most
likely kric kphf).

Outlook: low pressure developing along a stalled front and high
pressure centered to our N NE will keep an easterly flow across
the region through tue, allowing for increasing low-level
moisture, a chance for showers, and the potential for sub-vfr
ceilings from time to time (especially at eastern TAF locations)
mon-tue.

Marine
As of 410 pm edt Sunday...

late this aftn, sfc high pressure was centered over NRN new
england, with a frontal boundary well S and E off the coastal
carolinas. NE winds were 10-20 kt with gusts to 25 kt over the
marine waters. Waves were 1-3 ft, with seas 4-7 ft.

The high will remain over NRN new england tonight into early
tue, as an inverted trough develops along the dissipated frontal
boundary. Weak low pressure will lift NE well offshore along
this boundary late tonight into wed. This will result in strong
ne winds over most of the waters into Mon night, before
weakening and becoming NE or E late Mon night into early wed
morning.

Sca flags will continue into tonight for the lower james and the
currituck snd, thru Mon aftn evening for the ches bay, and thru
tue for the entire coastal waters. By Tue night and wed, the
wind will be ne-se less than 10 kt.

Equipment
As of 330 pm edt Sunday...

kdox radar is offline this afternoon due to an equipment issue.

Technicians are awaiting additional parts to complete repairs.

There is also a separate communications issue that is
preventing updates through usual free text message (ftm)

become available.
