Synopsis
The area will remain situated between an inland trough and
atlantic high pressure. A cold front is expected to stall over
or close to the region by the middle of next week.

Near term until 6 am Saturday morning
Convection has really struggled to get going across the local
area though we are flanked by scattered to numerous showers and
tstms to the west and south, mainly oriented along the surface
trough. Convection is expected to gradually move into our inland
southeast ga zones late this afternoon. The sea breeze is also
beginning to develop, though we may be beyond the time of
greatest instability by the time it begins advancing inland.

Only weak upper vorticity energy exists across southeast ga and
it's progged by the NAM to shift northwest through mid evening.

We show the greatest pops across inland areas through early
this evening, diminishing below 15% by late this evening.

Isolated convection will be possible over the coastal waters
later tonight as a weak land breeze develops.

Short term 6 am Saturday morning through Monday
Overall, the pattern looks as though it will favor decreasing
thunderstorm coverage through this period with continued warm
temperatures. Upper ridging will prevail this weekend, then
weaken through Monday as longwave troughing spreads into the
eastern half of the conus. At the surface, the pattern will
virtually remain the same through the period featuring an inland
trough and subtropical high pressure to the east. Model precip
fields almost all show less convective coverage each day, with
the lowest perhaps on Sunday. Still with temperatures reaching
the mid to upper 90s each day, it will be hard to not at least
get isolated coverage each afternoon. So the forecast contains
20-30 percent chances each day. While there is no significant
organized severe threat, it is interesting to note that model
soundings each day show dcape values in the 1000-1300 j kg
range. So whatever storms do develop could have an enhanced
ability to produce strong wind gusts. Can't rule out a strong to
marginally severe storm each day. Heat index values are
expected to top out around 105 each day, highest along the
coast, so it does not appear likely that heat advisories will be
needed.

Long term Monday night through Friday
A substantial pattern change for the southeast states with the
summer ridge giving way to broad mid upper level troughing. A
slow moving cold front is forecast to drift from the mountains on
Tuesday, over eastern ga and the coastal carolinas during mid week.

Confidence continues to slowly increase for numerous showers and
tstms across the forecast area during the middle of next week. The
increase in clouds and precip will result in lower temps that
average near or slightly below climo after Tuesday.

Aviation 19z Friday through Wednesday
Vfr conditions will prevail into at least early afternoon.

Thereafter we expect scattered shra tsra at or near the
terminals, with the highest probabilities of flight restrictions
to occur roughly between 20z and 23z. Impacts appear high
enough at ksav to include a tempo group for MVFR conditions, but
just vcts and CB clouds at kchs.

Extended aviation outlook: brief flight restrictions and
gusty shifting winds could occur within near thunderstorms,
especially during the afternoon evening hours. The chance for
thunderstorms associated flight restrictions could be greatest
starting Tuesday as a cold front approaches the region.

Marine
Moderate southwest flow will continue through tonight with seas
2-4 ft.

South to southwest flow will prevail through most of the period.

Wind speeds this weekend and into Monday will be enhanced at
times, surging into the 15-20 knot range. As we get closer to
the middle of next week speeds should be topping out in the
10-15 knot range. Seas should be 2-3 feet through most of the
period, though up to 4 feet around 20 nm and beyond this weekend
and early next week with the stronger periods of winds.

Overall, conditions are expected to remain below small craft
advisory thresholds.
