Synopsis
A weak area of low pressure will track northeast along the
carolina coast tonight and then push off the outer banks and
virginia capes Sunday. Weak high pressure builds into the area
Monday and settles off the coast Tuesday.

Near term through Sunday
As of 350 pm edt Saturday...

current WV imagery depicts a moist frontal band along the
carolina coast, with the rap model analysis showing a mid-level
trough near the sc coast, and surface observations and analysis
showing weak low pressure beneath the upper level feature.

Locally, a surface trough still lingers over central and
s-central va, with a sea-breeze boundary over the ERN shore.

Iso-sct showers tstms have developed over the piedmont to the w
of the surface trough where surface heating has been stronger,
with additional activity along the sea-breeze over the ern
shore. Coverage of showers tstms will remain limited through the
late aftn early evening, and then quickly dissipate later this
evening. Temperatures this aftn are generally in the mid 80s to
around 90f, with dewpoints in the mid 70s for many locations
resulting in some heat indices of 95-100f. Warm and humid
conditions will continue through tonight with lows of 70-75f.

Fog and stratus are expected to develop late tonight into early
Sunday morning primarily for the piedmont, central and s-central
va, interior NE nc, and the md ERN shore.

The system along the sc coast tonight will slowly drift newd
along the coast tonight and push off the outer banks and va
capes later tonight into Sunday. Guidance is mixed with regard
to how far N showers will extend, but the 17 12z href does
depict a decent signal for showers and perhaps a few embedded
tstms pushing into far SE va and NE nc primarily late tonight
into Sunday morning. Pops are highest (60-70%) along the coast
and adjacent to the albemarle sound and tapering off to 20-40%
from the peninsula to the lower ERN shore. There is a potential
for locally heavy rain with decent forcing for ascent combined
with pw value upwards of 2.25" and a deep warm cloud layer.

Pops gradually diminish through the aftn as the wave pulls off
the coast. However, some showers tstms could drift off the blue
ridge into the piedmont later in the aftn. Continued humid with
high temperatures ranging from the low mid 80s along the coast,
with low 90s from the i-95 corridor W where heat indices could
approach 100f.

Short term Sunday night through Tuesday
As of 350 pm edt Saturday...

Sunday night through Tuesday will largely be dominated by mid
and upper level ridging and weak high pressure at the surface,
as the frontal boundary finally pushes well off the coast. Hot
and humid conditions develop as 850mb temperatures rise to 19-
21c Monday and Tuesday, and this should support high
temperatures in the low mid 90s (upper 80s at the coast) both
days. Dewpoints potentially remain 70-75f during peak heating
resulting in heat indices of 100-105f. Morning lows will
generally be 70-75f. Pops are mainly 20% or less Monday, and
15-30% Tuesday.

Long term Tuesday night through Saturday
As of 350 pm Saturday...

large scale pattern at the beginning of the extended period
will feature ridging over the WRN atlantic southwest us, with a
strong upper low just S of the hudson bay. Weak troughing over
the southeast us (between the two ridges) will allow for
isolated- scattered aftn evening convection to develop on wed
(pops mainly 20- 40%). Ridging over the WRN atlantic slowly
retreats to the SE on Thu fri. This happens as the area low low
pressure (sfc-aloft) over the hudson bay moves eastward and the
trailing cold front slowly approaches the region from the nw. As
the cold front approaches the region by late thu, more
organized convection could develop (especially north west) late
thu and persist through the first part of Thu night. As a
result, have high-end chc pops from 18z thu-06z fri. The cold
front potentially stalls over the SRN part of the CWA from fri-
next weekend as the western atlantic ridge tries to build back
westward. If the front stalls, this would lead to continued
chances of scattered showers tstms (highest during the
aftn evening).

Highs mainly in the low 90s on wed-thu, cooling into the mid
80s for most areas by fri-sat. Forecast lows are mainly in the
low 70s on Wed thu, with mid-upper 60s inland around 70f near
the coast from Fri through next weekend.

Aviation 00z Sunday through Thursday
As of 745 pm edt Saturday...

showers tstms across SRN va NE nc earlier this evening have
weakened, leaving behind mid-high clouds. A weak area of low
pressure continues to develop along a stationary frontal
boundary near the sc coast. The aforementioned area of low
pressure will track NE along the boundary late tonight into
Sunday morning, bringing the potential for showers and embedded
tstms to ecg, and potentially orf. Latest hi-res guidance shows
that the best chc of pcpn will be from 11-18z at ecg 13-20z at
orf. While prevailing vsbys likely remainVFR MVFR, brief ifr
vsbys will be possible in the heavier showers tstms Sunday
morning. In addition, prevailing MVFR CIGS are likely at ecg orf
for much of the day on Sunday. Ifr fog stratus could once again
develop late tonight into Sunday morning, with the best
potential at ric (with lesser chances at phf sby). The low
gradually pulls away from the coast during the aftn, with a low
probability (15-20%) of an aftn shower or tstm.

Outlook... MainlyVFR conditions are expected to prevail Monday
through Thursday. A low probability of aftn evening showers tstms
will continue Monday and Tuesday. A higher chc of showers tstms
arrives by Wednesday and Thursday as a trough moves through the
area.

Marine
As of 350 pm edt Saturday...

high pressure off the coast is leading to 5-10 knot winds from
the east and southeast this afternoon. Waves are around 1 ft and
seas range from around 2 ft S to 2-3 ft n.

Winds will slowly become more southerly tonight but remain 5-10
knots. Global and high-res models have come into better
agreement regarding the expected track of low pressure currently
located off the sc coast. This low will move rather quickly
northeastward overnight and is expected to clip the area during
the day on Sunday. Will show increasing southeasterly flow of
10-15 knots from the southern ches bay southward into the
coastal waters through early afternoon as the low tracks
northeastward from the albemarle sound tomorrow afternoon. Winds
will quickly switch from onshore to offshore as the low passes
a given latitude. Southerly flow resumes by early Monday into
the mid week period. Waves will build to 1-2 ft (highest at the
mouth of the bay) on Sunday while seas will briefly build to 2-4
ft S and ~3 ft N as the low passes. Seas subside to 2-3 ft s
and closer to 3 ft N through mid week.
