Synopsis
A frontal boundary will stall across the carolinas today. Strong
high pressure remains anchored over new england through Monday
night. The front returns north as a warm front Tuesday. Low
pressure approaches the mid atlantic coast from the southeast
Tuesday night.

Near term until 6 pm this evening
As of 1000 am edt Sunday...

current regional radar mosaic depicts steady rain from the nrn
neck to the md ERN shore, with intermittent light rain or
drizzle from the piedmont across central va. The latest visible
satellite imagery shows thick cloud cover across most of the
area, with partly to mostly sunny conditions across far SE va ne
nc. Temperatures range from the upper 50s to mid 60s under cloud
cover and an in situ wedge, and are rising into the upper
70s around 80f under more Sun despite light onshore flow.

Latest high res data suggests rain persists for the NE portion
of the area, with sct showers potentially concentrating from the
wrn shore of the bay across to the va ERN shore. Pops will be
highest NE today (60-80%), tapering to chc for central portions,
then 20-30% for SRN va NE nc. Temperatures likely remain steady
nw n, and rise to the upper 70s low 80s SE under more sun, with
locally some mid 80s.

Short term 6 pm this evening through Tuesday
As of 400 am edt Sunday...

latest models keep the frontal boundary S of the local area tonight
with the best support for steady pcpn shifting north as well.

Despite a lack of a trigger, plenty of low level moisture noted
across the entire area of some light rain drizzle and fog. Lows 60
nw to 70 sern coastal areas. The weak cad wedge lingers Monday. The
difference Monday versus today will be the available moisture and
resulting cloud coverage as the tctsns show the potential for some
afternoon breaks of sunshine in the afternoon across the east. This
will likely lead to pcpn becoming more convection in nature (with
any thunder limited to sern third of the fa) after morning light
rain drizzle fog. Likely pops north, chc pops south. Another tricky
temp forecast with the nwrn zones remaining in the wedge with highs
65-70, upr 70s-lwr 80s across the se.

Latest guidance has the front remaining to the south Monday night.

Thus expect anther night with shwr chcs (highest pops north). The
airmass begins to modify as the wedge slowly washes out. Lows mid
60s NW to lwr 70s se.

Said front begins to lift back north as a warm front tue. Meanwhile,
both the gfs ECMWF show low pressure offshore approaching the mid
atlantic coast from the SE late Tue throwing some tropical moisture
towards the coast. This will enhance thunder chcs Tue afternoon
given a warmer and more humid airmass. Highs Tue upr 70s to mid 80s.

Long term Tuesday night through Saturday
As of 400 pm edt Saturday...

unsettled conditions through much of the medium range with multiple
low pressure systems impacting the region. We start the period
mainly dry Tuesday night with the area in the warm sector ahead of
the next front. This cold front approaches the region during the day
on Wednesday before slowly crossing the region late Wednesday night
into Thursday morning. Showers and thunderstorms will increase in
coverage from northwest to southeast Wednesday afternoon and become
more numerous by Wednesday evening. Both the GFS and ECMWF have this
front lingering across southeastern portions of the area during the
day Thursday into Friday allowing for the continued threat of
showers and thunderstorms. A secondary cold front makes its way
through the area on Friday with high pressure building back north of
the area Friday night into Saturday. It will be feeling more like
mid-august rather than fall on Wednesday with highs ranging from the
mid to upper 80s and dewpoints in the lower 70s. Highs on Thursday
could see a big range depending on the frontal timing position, will
go similar to the previous forecast with highs ranging from the mid
70s across the northwest to the mid 80s across the southeast. Highs
in the upper 70s to lower 80s Friday and mid 70s to lower 80s
Saturday. Lows in the 60s to near 70 Wednesday Thursday night, upper
50s to upper 60s Friday night.

Aviation 18z Sunday through Friday
As of 200 pm edt Sunday...

the current surface analysis shows high pressure over ny as of
18z and ridging swd through the piedmont. Meanwhile, a trough is
located over the carolina coastal plain into SE va, with an
attendant cold front extending back into nc. Stratus is located
n of the front with ric lifr as of 18z.VFR conditions prevail
along the coast in vicinity of the trough. Occasional -ra dz
continues at ric, and -shra have become concentrated on the wrn
shore of the bay, and could potentially impact phf this aftn.

The cold front will gradually push sewd overnight into Monday
morning. Ric is expected to remain ifr lifr through the taf
period, with CIGS dropping to ifr at sby overnight, and phf
toward Monday morning, while orf ecg generally remainVFR. Vsby
at ric is expected to remain 3-5sm this aftn evening, and then
deteriorate to AOB 2sm late tonight into Monday morning. Vsby at
sby phf is expected to drop to 2-5sm later tonight into Monday
morning. Stratus will be slow to lift Monday aftn from ric-sby.

An ene wind will increase to 10-15kt along the coast later
Monday morning into the aftn.

The potential for stratus reduced vsby continues Monday night
into Tuesday morning, with conditions improving Tuesday as the
front gradually lifts N through the region. The front remains n
of the area Wednesday, with another cold front approaching from
the NW Thursday and into the area Friday.

Marine
As of 400 am edt Sunday...

frontal boundary sits INVOF nc ocean waters ATTM W sfc hi pres
situated the ERN great lakes to NRN new england. Ene winds N of that
boundary expected to increase today to marginal SCA levels... While
waves seas build. A bit more uncertain is across the nc waters where
the boundary likely to linger or be slow to settle S today. While
wind speeds likely will remain marginal (at best) early this
week... Prolonged onshore fetch will likely result in seas AOA 5 ft
into midweek. Winds expected to become more SE Tue W speeds
generally AOB 15 kt.

increase by later today into Mon as strong sfc hi pres becomes

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.
