.WHAT HAS CHANGED...
The severe weather threat has ended for the entire forecast
area, as a cold front currently pushes off the southeast South
Carolina and southeast Georgia coast. Gusty winds behind the
front will linger through around midnight before subsiding. The
Wind Advisories for Charleston and Tidal Berkeley Counties have
ended. All Gale Warnings have ended.

.KEY MESSAGES...
- 1) Frost/freeze is possible tonight through Wednesday night.

.DISCUSSION...
KEY MESSAGE 1: Frost/freeze is possible tonight through
Wednesday night.

Cold high pressure will spread over the area behind the cold
front tonight. Temps will quickly drop this evening. A brief
advection freeze is expected Tuesday morning, mainly across far
interior GA/SC where temps could dip to 30-32F, where a Freeze
Warning is in effect. We will need to monitor the potential for
an expansion to Dorchester and Berkeley counties.

Tuesday night the high will be centered close to the area,
allowing surface winds to decouple in the evening. Skies should
be clearing out during the evening, so good radiational cooling
will occur overnight. Temps are expected to dip into the upper
20s far inland with lower to middle 30s elsewhere. Even where
temps don`t hit freezing, frost formation seems pretty likely.
We will likely need another round of Frost/Freeze headlines for
Tuesday night.

Wednesday night could also feature some frost issues across the
inland half of the area where temps dip to the low/mid 30s and
skies remain mostly clear.

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
VFR. Gusty winds associated with the passing of a cold front
will subside shortly after midnight tonight.

Extended Aviation Outlook: VFR conditions are expected to
prevail.

&&

.MARINE...
Winds across the coastal waters will continue to abruptly shift
WNW this evening as the cold front sweeps offshore. Small Craft
Advisories are now in place for all marine zones, including the
Charleston Harbor. Gusty winds and elevated seas will subside
by Tuesday morning.

&&
