Synopsis
Above normal temperatures will prevail much of the upcoming
week as high pressure offshore brings southerly winds. A series
of low pressure systems will bring a chance of rain Monday into
Tuesday, and again late next week. A cooling trend is expected
into next weekend.

Near term /through tonight/
As of 4 am Sunday... Much the same as previous day as an
expansive area of strato CU remains over off shore waters and
plenty of cirrus streaming over the carolinas in SW flow aloft.

The SE return flow around the ridge of high pressure over the
atlantic will push some of these clouds on shore through the day
and should see any stray showers stay mainly over the waters.

There may be some patchy fog around just around sunrise. The
cloud cover along with plenty of WAA have helped to keep
overnight temps close to 60. This will give a jump start to warm
day ahead. The WAA will battle the cloud cover allowing temps
to reach into the mid to upper 70s this aftn.

Low pressure tracking up the mississippi valley will increase
the chc of pcp into the mountains and although this will not
directly affect our area, there will be increased moisture
advection in SW flow aloft. Pcp water values near .65 inches
will increase over an inch through late Sun aftn. This may help
to trigger some showers over the central carolinas and may see a
stray shower reach farther east... Mainly west of i-95 late
Sunday, as well as increasing mid level clouds.

Short term /Monday through Tuesday night/
As of 4 am Sunday... Chief headline this period "warm and balmy"
and an offering of the best rain chances until late in the
week, in particular on Tuesday as a short-wave whisks overhead.

Dryish mid-level air will limit rainfall amounts and QPF output
far from stellar. The low-level heating and dewpoint fields
will continue to warrant a slight chance of a TSTM however, and
a few lucky folks may see higher local rainfall dumps from
convection. Pronounced drying in the mid-levels in wake of the
cold frontal passage late Tuesday night will curtail showers by
daybreak Wednesday, but no cold air follows the front.

Long term /Wednesday through Sunday/
As of 4 am Sunday... Brief high pressure intrusion via a back-
door cold front will bring a slightly cooler day on Thursday
with a lag of cooler air on Wednesday in wake of a frontal
crossing of the coast. Thursday morning lows may end up being
the coolest portion of the week, before warm air advection
cranks up again by Thursday night ahead of a potent southern
stream impulse. This system will offer the best rain chance of
late, and potentially a good soaking. Right now the amplified
nature of the shot-wave suggest a few strong to severe storms
cannot be ruled out late Thursday night into Friday. A few
showers may linger into Saturday beneath the cold pool of the
amplified trough, with drying and cooling through the day with
a cool morning lows in the 40s Sunday.

Aviation /08z Sunday through Thursday/
As of 06z... Expect mainlyVFR conditions through the TAF period
in a mild and moist weak southerly return flow. Winds will
generally be SE to S up to 10 kts in the aftn but otherwise 5
kts or less. An expansive CU field just off shore may get pushed
on shore in SE flow and therefore included period of sct to bkn
deck around 3 to 5 k ft... Mainly affecting the coastal
terminals. Expect some CU to affect inland TAF sites Sun aftn
also. The mid levels will continue dry but SW flow in the mid to
upper levels will continue to feed cirrus over the area. A few
shra possible late Sunday inland, but not enough in areal
coverage to warrant inclusion in the tafs as of yet.

Extended outlook... Flight category restrictions are possible in a
few bouts of showers and thunderstorms Mon through Tue and again
thurs night. ExpectVFR conditions after cold front moves through on
wed lasting into thurs.

Marine
Near term /through tonight/...

as of 4 am Sunday... Southeasterly return flow will continue
around atlantic high through the period. Winds will fluctuate
slightly from SE to S remaining 10 kts or less. Winds near shore
Sunday afternoon will be a little bit higher, in the 10 to 15
kt range, and gustier as the afternoon sea breeze circulation
sets up. The persistent southerly flow will push seas gradually
but overall will remain in the 2 to 4 ft range. Seas will remain
right around the 3 ft range through the period.

Short term /Monday through Tuesday night/...

as of 4 am Sunday... No advisories expected this period, but se
swell waves will keep sea heights relatively elevated given the
15 kt or less wind- speeds. Wave periods of around 10 seconds
will prevent steepness, and this will be co-joined by light to
moderate s-sw chop this period. A cold front will cross the
waters late Tuesday night accompanied by showers and isolated
tstms. Patchy marine fog or mist is possible on Tuesday. A
hearty sea breeze will produce gusts to 19 kt near shore in the
afternoons. Both mon/tue s-sw winds 15 kt or less sustained.

Long term /Wednesday through Friday/...

as of 4 am Sunday... Light winds Wednesday in wake of a cold
front can be expected, followed by a wind-shift to the n_ne
Wednesday night as a back door cold front pushes across the 0-20
nm waters. Briefly this intrusion will transition to light wind
as the high moves overhead Thursday afternoon. A strong and
progressive southern system will bring increasing se-s winds
late Thursday and an advisory may very well be needed for 25 kt
gusts late Thursday night ahead of its cold front. Strong storms
and numerous showers appear likely on the water Friday.
