.DISCUSSION...
KEY MESSAGE 1: Frost/freeze conditions through daybreak today
and again tonight.

Winds have gone light to calm across the region, a result of the
prevailing high pressure at the surface. Combined with clear skies,
a very chilly night is underway across the region. Several sites are
already reporting 32 degrees as of midnight. A Freeze Warning
remains in effect for a bulk of the SC Lowcountry and southeastern
GA. A Frost Advisory is in effect along the SC coastal counties,
where frost is forecast away from the immediate coastline. These
products are in effect through 9 AM.

If widespread freezing temperatures occur early this morning, then
this will end the local growing season and Frost/Freeze products
will not be issued for tonight/early Monday morning. However, if
only some areas observe freezing temperatures, then the growing
season continues and we will likely need Frost/Freeze products
tonight/early Monday morning. Regardless of the outcome, overnight
temperatures will range from low to mid 30s across the inland
counties and upper 30s to low 40s across the coastal counties.

.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
VFR through the 12Z TAF period at KCHS/KJZI/KSAV.

Extended Aviation Outlook: Expect VFR conditions to prevail.

&&

.MARINE...
Today and Tonight: High pressure will dominate over the marine
waters through tonight, yielding N winds 10 to 15 knots and seas
2 to 3 ft.

Monday through Thursday: As slowly high pressure expands across the
region and then eventually into the Atlantic, expect northeasterly
flow to take hold of the forecast and gradually ramp up throughout
the period. Wind speeds will generally range from 15 to 20 kt with
gusts up to 25 kts (even 30 kts possible across the offshore
waters). East-northeasterly swell will be on tap through the period
as well with seas ranging from 4 to 6 ft across the nearshore
waters, then 5 to 8 ft across the offshore waters. Small Craft
Advisories will likely be needed on Monday evening for the offshore
Georgia waters, and then eventually for the nearshore South Carolina
waters as well on Tuesday through the rest of the period. Mariners
should stay up to date with latest marine forecast before heading
offshore.
