.DISCUSSION...
KEY MESSAGE 1: Quiet weather and warming temperatures through
the weekend.

Sfc high pressure continues to prevail across the region
heading into the weekend, allowing dry conditions to persist. In
regard to temperatures, expect highs in the low to mid 70s
Friday to gradually warm back into the lower 80s by Saturday.
Temperatures continue to soar into the mid to upper 80s by
Sunday and Monday with the aid of mostly sunny skies and
southwesterly flow. May even see a few locations across our
interior Georgia counties take a shot at 90 degrees.

A strong backdoor cold front will then push south Monday
night/early Tuesday morning, resulting in breezy winds and
cooler, more seasonal temperatures for Tuesday and Wednesday. As
noted in the previous discussion, rain chances continue to
diminish, with latest guidance struggling to produce any
meaningful PoPs across the area. Otherwise, look for above
normal temperatures to return Thursday.

.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
VFR conditions will prevail at KCHS, KJZI, and KSAV through 06z
Saturday.

Extended Aviation Outlook: There are no high confidence
concerns.

&&

.MARINE...
Today through Tuesday: Conditions across the local waters are
expected to remain below Small Craft Advisory thresholds through
the weekend. Southwest flow will build a bit beginning early
Saturday morning and continue into Monday. There will likely be
periods of time with speeds getting into the 15-20 knot range.
The biggest impact for the waters will come Monday night and
into Tuesday in the wake of a backdoor cold front. The arrival
of some cooler air behind the front and a pinching of the
gradient will yield a notable northeasterly surge. Solid Small
Craft Advisory conditions appear likely for all of the waters,
with frequent gusts up to around 30 knots. There is even some
support for a period of gusts possibly up to around gale force,
meaning that Gale Watches and Warnings could eventually be
needed.
