NEAR TERM /THROUGH TONIGHT/

South to southwest winds of 10 to 15 mph will continue through the rest of the day as a warm front lifts through the area. Temperatures across the area are already in the lower 80s. Some locations could reach near or above record levels by peak heating as daytime highs will range in the lower to mid 80s over inland locations with lower 80s along the coast. Overnight lows will be similar to Monday night, with upper 50s to lower 60s across inland locations and lower 60s along the coast. There will likely be enough low level moisture from the Gulf to bring about fog development over portions of inland SE GA, but predominantly over NE FL during the predawn hours.

Along and ahead of an approaching cold front, showers and isolated storms will look to push into far interior SE GA during the later part of Tonight into Wednesday Morning.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/

Showers with potential embedded thunderstorms will build into the forecast area from out of the northwest on Wednesday, ahead of an advancing cold front with the highest chances for convection occurring over southeast Georgia and into northeast Florida west of Duval County and extending through the Suwannee Valley region. Rainfall amounts are expected to be upwards of 0.1 inches for affected inland areas. Breezy southwesterly-westerly winds will shift to become more out of the north as the front passes. High temperatures will drop significantly between Wednesday and Thursday with max temps in the upper 70s and lower 80s dipping down into the 60s following the frontal passage. Overnight low temperatures will experience a similar drop with min temps in the 40s and 50s dropping into the lower 30s over southeast Georgia and in the lower 40s for inland northeast Florida. Potential for patchy frost developing overnight Thursday and into early Friday morning over inland southeast Georgia.

LONG TERM /FRIDAY THROUGH TUESDAY/

Dry weather conditions will be in place for the Friday and Saturday as high pressure and dry air settle over the region. Chances for showers and possible thunderstorms will return on Sunday as high pressure moves off to the northeast and moist southwesterly flow develops over the region ahead of an advancing frontal boundary building in from out of the northwest. Overnight and early morning frost is forecasted for early Friday and again on Saturday night into Sunday morning, primarily affecting southeast Georgia and inland portions of northeast Florida. Temperatures will experience a warming trend through the weekend and into the beginning of next week with max and min temps rising to be above the seasonal average by Monday.

AVIATION /18Z TUESDAY THROUGH 18Z WEDNESDAY/

VFR conds and South to Southwest winds at 5-10 knots through the afternoon, with a weak SE sea breeze wind shift expected at CRG/SSI/SGJ by 18-20Z time frame. VFR conds continue into the early evening hours. Fog chances are expected after 06Z across inland sites of GNV/VQQ, clearing closer to 12Z. Shower chances remain low during the TAF period, left out any mention for now.

MARINE

Departing high pressure along the eastern seaboard will bring breezy southerly winds across the local waters through the rest of Today. Winds shift to become southwesterly by Wednesday as an approaching cold front begins to press across the waters. By late Wednesday into Thursday, winds shift to become northwesterly to northerly behind the front, with Small Craft Advisory conditions possible by Thursday. Conditions may persist on Friday and possibly into Saturday as winds shift to the northeast and east.

Rip Currents: Moderate risk of rip currents as surf/breakers slowly build into the 2-3 ft range.

FIRE WEATHER

High pressure will continue to move off to the northeast of the region today as a warm front lifts north across the area and winds shift to become southerly. A cold front will approach from the northwest Wednesday morning with increasing breezy southwesterly winds 10-15 mph. Scattered showers will spread into the Suwannee Valley and inland Southeast GA with afternoon isolated thunderstorms, but less chances eastward towards the coast as showers dissipate late in the day along the front, limiting total rainfall amounts. Increasing southwesterly surface and transport winds will produce areas of high daytime dispersions on Wednesday.

Much drier air mass arrives Thursday and persists through Friday as strong high pressure builds from the northwest. Very low dew points into the upper teens/low 20s over inland Southeast GA and into the Suwannee Valley of Northeast FL will create critically low Min RH values 20-25 percent Thursday and Friday afternoons. While winds appear marginal 10-15 mph, gusts may exceed 25 mph at times and support Elevated fire danger conditions Thursday. Southeast Georgia 10 hour fuels appear to not reach thresholds as well, staying well above 6 percent.

FOG POTENTIAL AND OTHER REMARKS..Areas of fog, locally dense, will develop late tonight into early Wednesday morning across the I-75 corridor to near highway 301 over Northeast FL.
