.UPDATE...
Expanded areas of dense fog to encompass the I-75 corridor and
into inland SE GA with this update. A Dense Fog Advisory may be
needed for the I-75 corridor early Saturday morning.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
High pressure ridge will sink to the south through the night. The
position of the ridge will yield a flow from the southwest. This
flow across the Gulf waters will produce the potential for inland
fog Tonight. Lows Tonight in the mid to upper 50s.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/...
High pressure over the Florida peninsula will continue to shift off
to the east as a cold front presses down from out of the north and
slowly stalls over the region by the end of the weekend. Initially
foggy conditions on Saturday morning with a potential for showers
and a slight chance of embedded thunderstorms developing over inland
southeast Georgia in the afternoon and evening, with breezy
southwesterly winds building ahead of the front. High temperatures
for this weekend will be in the upper 70s and lower to mid 80s with
overnight low temperatures dropping down into the lower 60s and 50s
with cooler temps over inland southeast Georgia. Max temps on
Saturday may challenge established record highs for the day.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
An advancing cold front moving in from out of the northwest will
bring showers over the forecast area before the end of the week,
with initially onshore winds shifting to become more out of the
northwest by Thursday. Temperatures will drop down to be below the
seasonal average after midweek as colder air following the frontal
passage settles in over the region.

&&

.AVIATION /00Z SATURDAY THROUGH 00Z SUNDAY/...
Another round of inland fog is anticipated to develop after 06Z
tonight. Areas of dense fog will be possible at GNV and VQQ causing
IFR/LIFR conditions. Some fog may reach JAX and CRG but VSBYs will
likely remain above MVFR. Fog should lift and dissipate by 14Z.
Otherwise, calm winds overnight become WSW 5-10 kts after 15Z.

.MARINE...
.SYNOPSIS...

Weak high pressure ridge will sink south of the area through
Saturday. A weakening and mostly dry frontal boundary will then push
southward through the Georgia waters on Saturday night, with this
boundary pushing across the northeast FL waters early on Sunday
morning. High pressure will build eastward on Sunday towards the Mid-
Atlantic states by Monday afternoon, with breezy onshore winds
developing across our local waters from Sunday afternoon through
Monday afternoon. A stronger cold front may then push eastward
across the southeastern states on Wednesday into Thursday, with
southerly winds expected to develop ahead of this front
beginning on Tuesday evening.

Rip Currents: SE GA Low Saturday
              NE FL Low Saturday

.FIRE WEATHER...
     LOW DISPERSIONS TODAY AT THE COAST AND NORTH-CENTRAL FL..

.DISCUSSION...

Breezy southwesterly winds will continue across inland southeast
Georgia this afternoon ahead of an approaching front. Dispersions
today will range from fair in southeast Georgia to low at the
Atlantic coast and north-central Florida. Breezy southwesterly winds
will spread across the entire area on Saturday as the aforementioned
front pushes southeastward into and through the region overnight
Saturday into Sunday. This will lead to good daytime dispersions
area-wide and an increase in low level moisture. Unfortunately, this
frontal passage will lack any much needed rainfall for the area
suffering from severe/extreme drought conditions. Northeasterly
winds behind the front Sunday will trend easterly by Monday.

FOG POTENTIAL AND OTHER REMARKS...Patchy to areas of fog are likely
Saturday morning. Dense fog will be focused along the I-95 corridor
this morning and I-75 corridor Saturday morning.
