Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles.. A summer-like pattern to develop into the weekend as high pressure becomes anchored offshore. A weakening cold front may bring a few showers late Thursday and Friday. A stronger frontal system will bring rain and rougher seas early next week. Gusts to 20 kt can be expected each afternoon inshore due to a strong sea breeze.

Synopsis
A cold front will approach the mountains from the west late this
afternoon and evening, then stall out and dissipate over the mid-
atlantic tonight. A moist southerly return flow on the western
periphery of a strengthening bermuda high will prevail Friday
through the weekend.

Near term /through tonight/
As of 910 pm edt Wednesday...

the skies had cleared across nc this evening. High pressure will be
overhead tonight with light winds. There may be a bit more patch fog
around sunrise that currently forecast due to the saturated ground
under clear skies and light winds. We may have to add some patchy
ground fog for later tonight, especially in the fog prone and soaked
valley areas near the lakes, rivers, and even smaller creeks. The
temperature / dew point spreads were already 5 degrees or less in
many areas. Lows should fall into the 60-65 range, except upper 50s
over the northern piedmont.

Short term /Thursday and Thursday night/
As of 335 pm edt Wednesday...

skies will be generally sunny for much of Thu morning, with the mid
level ridge axis sliding to our east, although high clouds will be
increasing as the weakening line of convection approaches from the
west, along with a weakening surface trough that brushes our W and n
sections late Thu through Thu night before lifting up into the mid
atlantic region. Warm and stable 850-600 mb air will inhibit
convection in our area through early afternoon, despite surface
dewpoints within a few degrees of 60, and this is further supported
by the latest hi-res wrf-arw/nmm runs which stay dry in our area
through 18z. By mid afternoon, however, a weakened version of the
convective line will be moving into the western cwa, accompanying a
30-40 kt 850 mb ssw jetlet, weaker than its previous state but still
enough to support low level mass convergence over central nc, mainly
from very late afternoon until shortly after midnight. Forecast
soundings show mostly elevated instability increasing by evening,
peaking in the 800-1200 j/kg range, and deep layer shear ranging
from around 40 kts west to around 20 kts east, with column
moistening as high pw values of 1.5-1.75" advect in from the sw.

Detrimental to maintenance of this convection will be the lack of
dynamic forcing for ascent, as any weak dpva will track well to our
nw, although models do indicate a pocket of enhanced upper
divergence tracking NE through the area Thu evening, which may
support greater storm coverage. For now, will hold onto low-end
likely pops west, with lower chances through the central CWA and
just small chances east, where deep layer shear and dynamic forcing
for lift will be weaker closer to the departing ridge. With
thicknesses higher than yesterday tempered by the increase in
clouds, expect highs from near 80 NW to the mid 80s se. Lows thu
night ranging from the low 60s NW to the upper 60s se. -gih

Long term /Friday through Tuesday/
As of 325 pm edt Wednesday...

a weak surface tough associated with dying overnight convection is
forecast to stall over the coastal plain and then retreat back to
the west on Friday as the subtropical ridge amplifies off the
southeast coast. The ridge, and associated rising thicknesses will
peak on Saturday (thicknesses of 1410-1420m), with highs accordingly
peaking in the upper 80s to lower 90s, just short of record highs.

Convection each day should mainly be tied to the seabreeze and higher
terrain in southwesterly flow and no strong forcing. However, with
strong instability forecast, owing to a plume of steep mid-level
lapse rates off the mexican plateau, there could be a large hail and
damaging wind threat, more so on Saturday when models suggest a
shallow tropopause disturbance/jet moving lifting through the deep
south that could aid in triggering storms. Confidence in this
feature and whether or not storms will be able to develop is still
low at this point.

The ridge will hold on Sunday and then give a little to a strong
upper low forecast to lift from the southern plains to the great
lake by Monday. Pops will increase on Monday as the associated cold
front advances east across the mountains. Shear looks favorable for
severe weather, but instability is questionable on Monday. Temps
will accordingly be knocked back toward normal for the middle of
next week.

Aviation /06z Thursday through Monday/
As of 145 am edt Thursday...

24 hour TAF period:VFR conditions associated with a dry/capped
airmass will prevail through mid to late afternoon. Scattered
convection (remnants of a squall line expected to cross the
mountains this afternoon) will be possible 20-00z at int/gso
terminals and 00-04z at eastern terminals, with the relative best
chance at int/gso terminals given an increasingly dry/hostile
airmass with eastern extent. Sw/wsw wind gusts as high as 20g35kt
will be possible in assoc/w any convection. Otherwise, calm or light
ssw winds early this morning will increase to 10-15 knots a few
hours after sunrise, with gusts as high as 20-25 knots this
afternoon (after ~15z), highest at the int/gso terminals.

Outlook: thoughVFR conditions will prevail through the majority of
the upcoming weekend, adverse aviation conditions are periodically
expected. Examples include ifr/lifr ceilings expected to develop
each morning sat/sun/mon between 08-12z, lifting/scattering out to
vfr by 12-15z. Additionally, isolated to scattered afternoon/evening
(21-03z) convection will be possible fri/sat. Should convection
develop and/or propagate into the region fri/sat, environmental
conditions would strongly support severe weather. Otherwise, expect
the best overall potential for convection Monday evening/night in
assoc/w a cold front /squall line/ progged to track eastward through
the carolinas. -vincent
