AVIATION
(06Z TAFS)
Issued at 151 AM EDT Thu Apr 25 2024

MVFR visibilities are expected to develop overnight at VQQ, with brief periods of IFR conditions possible through the predawn hours. Confidence was not high enough to indicate a sustained period of IFR conditions at VQQ at this time. A brief period of fog may also materialize around sunrise at GNV, but confidence in sub-VFR visibilities was too low to include restrictions at GNV at this time. Otherwise, VFR conditions will prevail at the regional terminals, with periods of broken ceilings around 6,000 feet possible at SSI during the predawn and morning hours, with this cloud cover then expanding southward to the northeast FL terminals after sunrise. Light southwesterly surface winds overnight will shift to westerly after sunrise, with speeds at the regional terminals increasing to 5-10 knots before 15Z. The Atlantic and Gulf coast sea breezes will then develop towards noon and will push more quickly inland than prior days, resulting in surface winds shifting to westerly at GNV following the passage of the Gulf coast sea breeze, with sustained speeds increasing to around 10 knots. Surface winds will shift to easterly at SGJ following the passage of the Atlantic sea breeze boundary shortly after noon, with sustained speeds increasing to 10-15 knots during the early to mid afternoon hours. Surface winds elsewhere will shift to easterly or southeasterly during the early to mid afternoon hours, with speeds increasing to around 10 knots, except at GNV, where this wind shift will likely not occur until around sunset as the Atlantic and Gulf sea breeze boundaries collide around U.S.
Highway 301. Surface winds will then shift to southeasterly or southerly by the mid-evening hours at the regional terminals, with speeds diminishing to 5-10 knots.

UPDATE
Issued at 827 PM EDT Wed Apr 24 2024

Forecast on track with mainly seasonable temps on track under mainly clear skies tonight. Lows in the 50s inland and near 60 along the Atlantic Coast. Enough boundary layer cooling across inland NE FL along the Suwannee River Basin will lead to some patchy fog formation around sunrise Thursday morning, but significant fog is not expected at this time.

SHORT TERM
(Thursday through Friday night)

A weak cold front approaches SE GA Thursday morning and slowly pushes south to the FL/GA line by the evening hours. Conditions look to be too dry to produce any precipitation. Expect clear skies in the morning with increasing cloud coverage in the afternoon. Temperatures will be in the mid to upper 80s inland with coastal temperatures staying slightly cooler.

Friday, the weak cold front shifts north and east a bit so that it drapes across SE GA once again and will dissipate by the evening.
Conditions are still too dry to produce any precipitation. Winds will begin to increase in the afternoon as pressure gradients begin to tighten up between a low pressure out west and the high pressure off the northeast coast. Temperatures inland will be in the mid 80s with temperatures in the low to mid 80s closer to the coast.

LONG TERM
(Saturday through next Wednesday)

Predominantly dry conditions are expected for the forecast period as high pressure ridging at the surface dominate the region.
Winds will be breezy Saturday and Sunday due to tightening pressure gradients and easterly winds. Monday to Thursday, as the high pressure makes its way down the east coast and settles off the coast of the Carolinas, it will allow the seabreeze to make its way well inland each afternoon.

Temperatures for the weekend will be in the low to mid 80s, staying slightly cooler at the coast. Temperatures will steadily increase into the 90s by mid week.

MARINE

High pressure will dominate the waters through tonight with a sea breeze developing near shore during the afternoon and evening hours.
A weak trough/front will approach the waters on Thursday with high pressure building back in through the remainder of the forecast period. Onshore flow will strengthen Friday and build seas through the weekend.

Rip Currents: Moderate risk of rip currents will be present through the end of the week with risk increasing to High this weekend as onshore winds and surf increase.

FIRE WEATHER

A high pressure ridge across northeast FL will push southward as a weak frontal boundary begins to move into southeast GA Thursday morning. The front will stall Thursday evening just north of the FL/GA line and dissipate by Friday. Today, minRH values range from 30-35% inland with higher values along the coast. West to southwest winds expected around 5 mph, but breezier southeast winds of 10-15 mph are expected along the coast due to the sea breeze. Thursday, calm variable winds expected with the sea breeze making its way in at the coast from the east to southeast near 10 mph in the afternoon. Friday through the weekend, most locations will see prevailing east to southeast winds at 10-15 mph with patchy high dispersions area wide.
