Synopsis
Very warm temperatures will develop over the next couple of
days and continue for most of the forecast period. There is very
little chance of rain during this time as well.

Near term through tonight
As of 700 pm Wednesday... Convergence and convection holding s
through W of the forecast area early this evening, with kltx vad
wind profiler showing 10-15 kt ese-e flow in the lowest 3000 ft
at this time. This will help in raising absolute humidity about
the region, up several degrees overnight, washing away the
recent, slight low-level drying. 1-meter wind-speeds in a down
trend mode, dipping to <4 mph sustained at 12z Thursday, with
2-meter rh approaching 90 percent. The richest low-level water
vapor resides across NE sc and here, look for patches of fog
and mist into pre-dawn, mainly clear overnight, TSTM debris ice
clouds may sweep along the i-95 corridor later tonight, due to
the earlier convective blow-up east of athens ga.

As of 400 pm Wednesday... Clouds were a bit stubborn to leave today
across our local area in stiff northeasterly on shore flow. High
pressure will continue to extend down from the north as it shifts
off the mid atlantic coast through thurs. The gusty on shore flow
will shift around to the southeast and then become southerly on
thurs as it diminishes. Tonight will be dry with temps in the lower
60s over northern zones and the mid 60s elsewhere.

Thursday will be a transitional day back to warmer weather as a
warmer and moister return flow begins to develop at the sfc and
ridge builds up through the southeast conus. This will increase the
relative humidity and drive temps back up. Highs should reach back
up to the mid 80s to near 90 inland. Models show a kink in the ridge
for late thurs into early Fri as a shortwave pushes the tail end of
cold front by just north. This should act to shift winds around to a
more SW to W flow into fri. Overnight lows will be back up a few
degrees thurs night as dewpoints creep back up.

Short term Friday through Friday night
As of 400 pm Wednesday... The story for the memorial day weekend
will be the heat as a potent mid level ridge will be meandering
across the southeast. Some guidance is hinting at the feature
becoming more elongated and suppressed to the south which could
at least allow for some convection overnight Saturday into
Sunday morning. Have not included mentionable pops at this time
opting to wait on a little more guidance and consistency. Highs
will be in the lower to middle 90s with overnight lows in the
steamy 70s.

Long term Saturday through Thursday
As of 400 pm Wednesday... No real changes in sight for the extended
forecast as the massive ridge hanging around the southeast will
be the dominant feature. There is a hint of a pattern change
late next week as a stronger trough well to the north attempts
to break down the ridge. In between it will be a hot grind with
daytime highs well into the 90s and steamy overnight lows in the
70s. No pops at this time but a northwest flow MCS is always a
small possibility depending on the configuration of the ridge.

Aviation 06z Thursday through Monday
As of 06z... East to southeast surface winds are bringing in a
shallow layer of moisture from the ocean that is showing up as
scattered stratocumulus clouds 1500-2500 feet agl. These could
merge into a low stratus stratocumulus ceiling inland beginning
as early as 09z, potentially affecting the flo and lbt airports.

The Sun should burn through any low clouds between 13-14z with
vfr conditions expected throughout the area today. No deep
convection is expected due to considerable dry air aloft.

Seabreeze winds could gust to 15-18 knots this afternoon and
early this evening at the myr and cre airports.

Extended outlook... ContinuedVFR conditions are expected through
the weekend as high pressure dominates. There is a slight
chance of MVFR conditions each morning from low stratus and or
fog, and also from isolated afternoon thunderstorms.

Marine
As of 700 pm Wednesday... E waves every 5 seconds presently at
3-4 feet, will drop 1-2 feet overnight , gradually, as winds
abate. No tstms or fog, no showers overnight.

As of 4 pm Wednesday... Seas up between 4 to 5 ft in places with
stiff NE winds this afternoon will begin to diminish and veer
around through tonight into Thursday as high pressure drifts
farther off of the mid atlantic coast. NE winds up around 15 kts
with higher gusts will come around to the E through tonight and
then SE to S on thurs as they diminish some. This will allow
seas to drop less than 3 ft by thurs aftn.

The tail end of cold front moving by to the north of the waters will
push winds around to the SW to W by Fri morning which will kick seas
back up a bit over 3 ft into thurs.

Ilm watches warnings advisories
Sc... None.

Nc... None.

Marine... None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
