.DISCUSSION...
KEY MESSAGE 1: Patchy to areas of fog possible across Southeast
South Carolina through daybreak this morning.

Latest satellite imagery and sfc obs indicate visibilities have
lowered below 1 mile in some spots across the Tri-County Area and
Colleton County early this morning, mainly due to shallow fog.
Condensation pressure deficits remain low in areas that experienced
rainfall within the last 12-24 hours while light/calm winds persist
with high pressure filtering into the region. The setup remains
favorable for patchy to areas of fog occurring across the area
previously noted with a few spots possibly experiencing locally
dense fog near low-lying locations through daybreak. A Special
Weather Statement could eventually be needed to address locally
dense fog.

KEY MESSAGE 2: Dry conditions and seasonable temperatures expected
this weekend and into next week.

Dry high pressure will build across the Southeast United States this
weekend and prevail through early next week. Cold air advection post
fropa will set the stage for noticeably cooler temps today and
Sunday, although are expected to remain above normal for afternoon
highs, generally in the mid-upper 70s this afternoon, then low-mid
70s Sunday afternoon. Overnight periods will feature cooler temps as
well while high pressure settles across the area, sfc winds become
rather light, and a fair amount of radiational cooling takes place
under more substantial clearing. In general, temps should dip
into the mid 40s inland to mid-upper 50s near the coast tonight,
then a few degrees cooler Sunday night.

High pressure will reside across the Southeast early into the middle
of next week, setting the stage for rebounding temps as a west flow
becomes more pronounced across the local area. In general, afternoon
highs should return to the mid-upper 70s. However, light winds and
radiational cooling nights will continue to support lows in the low-
mid 40s inland to low-mid 50s near coastal areas into the middle of
next week.

.AVIATION /07Z SATURDAY THROUGH WEDNESDAY/...
Light northwest flow is expected at all terminals tonight while
a cold front shifts further offshore and away from the area.
Recent amendments to the CHS/JZI have been made to address a
patchy to areas of fog developing across the area, some of which
could become dense at times in a rather thin layer. TEMPO groups
with 1/4 to 1/2SM vsbys due to fog have been included at CHS
through 12Z this morning. MVFR conditions continue at JZI
through 12Z as well this morning, although could eventually
experience vsbys below 1SM as well approaching daybreak. Conditions
improve to VFR thereafter with a north-northeast flow setting
up during the day. VFR conditions are expected to prevail at
SAV through 06Z Sunday.

Extended Aviation Outlook: Prevailing VFR conditions are expected at
CHS/JZI/SAV terminals.

.MARINE...
Behind the cold front that pushed through yesterday, west-
northwesterly winds will become north-northeasterly throughout the
morning hours. As this occurs, the winds will become increasingly
breezy with gusts ranging from 15 to 20 knots, highest across the
South Carolina offshore (20-60nm zones) waters, and weakest in the
nearshore Georgia waters. Seas of 3 to 5 feet are expected. Winds
remain intermittently breezy overnight into Sunday, with gusts
increasing back into the 15 to 20 knot range throughout the daytime
hours. Thereafter, winds and seas should gradually diminish into
early next week with generally quiet conditions and no marine
hazards expected.
