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.

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

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.
