Synopsis
Dry high pressure will prevail today with a weak upper
disturbance moving through tonight. A stronger storm system
will then impact the area Saturday night and Sunday. Much
colder temperatures will return early next week followed by
increasing temperatures and rain chances into the middle of
next week.

Near term through tonight
No changes with this update.

Rest of today: low pressure is forecasted to track over the
ohio river valley, allowing winds to shift to the south-
southwest. The combination of return flow and at least partly
sunny conditions should allow temperatures to peak in the low to
mid 60s.

Tonight: the center of low pressure will continue to track to the ne
across the mid-atlantic states. The associated cold front is
forecast to sweep across the southern appalachians between 9z to
12z. Within the mid-levels, a weak short wave will ripple across the
forecast area this evening, well ahead of the sfc cold front. High
resolution cam guidance indicates only a few showers will be
possible tonight, supporting only schc pops across the sc
lowcountry. Given thick clouds and continued SW winds, low
temperatures should verify in the mid 40s.

Short term Friday through Sunday
Generally high confidence this period. Surface high pressure will
maintain mainly dry conditions Friday although a few showers cannot
be completely ruled out toward the csra where moisture and
instability will be increasing a bit. A warm front is expected to
develop over or near the area Friday night ahead of low pressure
near texarkana and this could lead to a few showers into Saturday,
mainly well inland, but it looks like the bulk of the rain will hold
off until Saturday night with clearing on Sunday. Still appears
instability will remain low as thus the risk for thunderstorms as
well. Rain amounts still look to average around a half inch with
some locally higher amounts. Temperatures will be well above normal
through Saturday (when it could get near record highs especially at
ksav), then return back to near normal Sunday (although highs are
more likely to occur earlier in the day due to the cold advection
kicking in during the day behind the front). It will also become
breezy Saturday afternoon and continue through Sunday with a lake
wind advisory possible for lake moultrie starting Sunday.

Long term Sunday night through Thursday
High forecast confidence through Monday night before confidence
lowers into mid week. High pressure will be building from the
northwest behind an upper trough pushing offshore to start the
period. The high should be centered near nc va by Tuesday with a
coastal trough developing off the southeast u.S. Coast. Thereafter
the forecast becomes more uncertain as some model guidance is more
progressive with the high shifting offshore than others, but for now
we trended toward the slower ECMWF solution which matches better
with the GFS ensemble mean. So we are indicating small rain chances
returning Tuesday night and increasing Wednesday before diminishing
behind a cold front into Thursday.

Most, if not all, locales should be below freezing Monday morning
with inland areas in the mid to upper 20s and wind chills near 20
degrees. It's not out of the question that coastal areas reach wind
chill advisory levels of 15 degrees, especially near charleston
where the colder temperatures are expected. Highs Monday should only
range from around 40 near the santee river to 50 near the altamaha
river. Temperatures Monday night look a bit milder especially near
the coast due to more onshore winds but interior areas could reach
similar temperatures as Monday morning. Thereafter temperatures will
moderate into mid week to near or above normal levels before
possibly returning back below normal again Thursday behind the cold
front.

Aviation 18z Thursday through Tuesday
18z tafs:VFR.

Extended aviation outlook: restrictions possible as early as Friday
but more likely Saturday night into early Sunday, probably ifr or
worse at times due to low clouds and moderate rain. Also,
breezy gusty conditions are expected later Saturday into
early Monday.

Marine
Today and tonight: broad high pressure will remain centered over fl
as a cold front crosses the southern appalachians late tonight.

Winds are forecast to range between 5 to 10 kts south during the
daylight hours. Winds should shift from the west and increase to 10-
15 kts. Seas are forecast to remain around 1 ft across the near
shore waters and 2 ft beyond 20 nm. Tonight, seas will generally
remain unchanged, possibly occasional 3 ft waves across the outer ga
waters.

Friday through Tuesday: no concerns through Saturday (although there
is a low risk of sea fog developing Saturday Saturday night over the
nearshore waters), but conditions will be deteriorating
significantly Saturday night and Sunday as a strong cold front
affects the area with some heavy showers and possible thunderstorms
(mainly near the gulf stream). Wind could even gust near gale force
across the ga waters beyond 20 nm Saturday night into early Sunday
night. Otherwise, small craft advisories are expected for the entire
area. Should see improving conditions Monday as winds turn offshore
and diminish with the weakening cold air advection.

Tides coastal flooding
Tides coastal flooding... Astronomical tide levels will be high early
next week and strong north northeast winds will help contribute to
even higher levels which could lead to minor saltwater flooding
around high tide, especially starting Monday. Thus, coastal flood
advisories will be possible.
