LONG TERM /MONDAY THROUGH FRIDAY/

Main Highlights This Period: mon-thu

- Seasonably Cool and Dry Weather into Early Next Week. - Increasing Coastal and Marine Hazards Forecast Next Week.

Chances for showers will increase by Tuesday and through next week as high pressure drifts more towards the northeast and upper level short waves cross over the region, followed by a potential low pressure formation southeast of the forecast area, situated over nearby Atlantic waters by the end of the week. Initially cool temperatures will experience a warming trend through next week with temps rising to be near and above the seasonal average by the end of the forecast period.

AVIATION /00Z SATURDAY THROUGH 00Z SUNDAY/

SKC VFR conditions prevail amid light WNW winds at or below 10 knots through tonight. Winds shift NW and then north through Saturday with wind around 8-12 knots and occasional gusts to 15-18 knots during the afternoon while a bout of scattered high cirrus passes during the late morning hours.

MARINE

High pressure will be located to the northwest through the weekend. The high will build more to the north early next week, with weak troughing developing over area coastal waters. Small Craft Advisory conditions are expected Tonight, and again Monday night and continue through at least the middle of next week.

Rip Currents: Strong offshore winds developing Today and remaining in place through Saturday should yield a low risk of rip currents. Northeasterly winds developing by Sunday and into early next week will lead to a return to an elevated risk of rip currents.

FIRE WEATHER

- High Daytime Dispersions For Se Ga And Inland Ne Fl Today ELEVATED NIGHTTIME DISPERSION VALUES AT COASTAL LOCATIONS - Tonight

A much cooler and drier air mass will overspread our area today and into the weekend. Breezy northwesterly surface and transport winds today will yield high daytime dispersions for southeast Georgia and much of inland northeast Florida. Min RHs will be in the 30s today and Saturday. Breezy transport speeds persist tonight at coastal locations, where elevated nighttime dispersion values are forecast. Surface and transport winds will then shift to northerly on Saturday bringing very good dispersions. Winds decrease and shift to northeasterly by Sunday gradually increasing moisture to the area. Fair to good daytime dispersions are expected region-wide on Sunday.

FOG POTENTIAL AND OTHER WEATHER REMARKS: Significant fog is not expected through the weekend. Patchy to areas of frost formation are possible late Saturday night and early Sunday morning across inland portions of southeast GA, the Suwannee Valley, and portions of inland northeast Florida.
