NEAR TERM
Issued at 303 PM EDT Sun May 19 2024

For the latest NE FL and SE GA Daily Key Messages please visit: https:// www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf

Line of showers and storms are currently skirting the Altamaha River Basin in SE GA along the cold front. Showers and storms will begin to develop across SE GA and eventually towards NE FL once the cold front begins to meander south during the late afternoon.
Main concern for any storms which do develop will be damaging wind gusts up to 60 mph, as DCAPE values hover around the 1000 J/kg range. Activity will shift towards the coast during the early evening hours. Coastal showers will linger through the overnight hours over the SE GA coast, with some activity possible during the early morning hours along the coast in NE FL. A northeasterly flow will become established during the overnight hours as the cold front clears the area and high pressure begins to build down from the northeast. Overnight lows in the mid to upper 60s for inland locations, with coastal locations hovering near the 70 mark.

SHORT TERM
(Monday through Tuesday night)
Issued at 303 PM EDT Sun May 19 2024

High pressure wedges down the east coast Monday with an upper level trough in place. Onshore flow will allow the sea-breeze to make itself well inland, pulling some PWAT values of 1-1.4" along with it. Rain and storm potential will be between 25-45% in the morning along the coast and inland to the 301 corridor, increasing inland for NE FL to 50-60%. Chances drop below 10% after sunset. Partly cloudy skies and onshore winds will keep high temperatures in the low to mid 80s area wide with temperatures in the upper 70s to low 80s along the coast. Winds will die down in the evening hours, with skies becoming mostly clear inland.
Overnight temperatures will be in the low to mid 60's staying in the upper 60s to low 70s along the coast. Tuesday, weather will be similar to monday just a bit drier, causing lower chances of 20-40% for storms and precipitation for NE FL in the morning and afternoon.

LONG TERM
(Wednesday through next Sunday)
Issued at 303 PM EDT Sun May 19 2024

High pressure continues to build into the area Wednesday with an upper level ridge moving in from the west. Expect mostly clear skies for the rest of the week, becoming partly cloudy Friday afternoon. Models show the next best chance for rain will be over the weekend in the afternoon and evening hours as PWAT values increase to 1.5"+ and an upper level trough moves into the area.
Temperatures will slowly climb into the 90s by Thursday and stay through the weekend with overnight temperatures will be in the upper 60s to low 70s.

AVIATION
(18Z TAFS)
Issued at 140 PM EDT Sun May 19 2024

VFR clouds around at this time with scattered to broken cumulus around 3500-4500 ft. First signs of convection so far over inland southeast GA, but deepening cumulus field will result in chance of showers and storms rest of the aftn with TEMPO groups in place, with lowest confidence for SGJ and GNV at this time. Could be strong gusty winds that accompany storms around SSI and then near JAX by 22z and 00z, respectively. Showers and storms expected to diminish in coverage and intensity after 02z-04z time frame as frontal boundary sags southward. Low clouds will begin to develop overnight into Monday morning that may be close to IFR but mainly MVFR. Sfc winds prevail from the west about 8-12 kt and will shift to northerly and northeast by Monday morning.

MARINE
Issued at 303 PM EDT Sun May 19 2024

Some of these storms may contain strong gusty winds and heavy downpours at times. Breezy flow from the north- northeast overnight into Monday behind the cold front. Wind speeds will be near small craft advisory levels over the southeast Georgia waters Monday morning. High pressure builds directly over the waters during the middle part of next week.
