NEAR TERM
Issued at 343 AM EDT Wed May 8 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

High pressure ridging extending outward from over the Florida peninsula will dominate the weather pattern today for the southeastern US with mostly clear skies and overhead subsidence inhibiting the development of diurnal sea breeze showers. Patchy to dense early morning fog developments will become dispersed by midmorning. High temperatures over inland areas today will reach up into the lower to mid 90s and into the upper 80s and lower 90s along the coastline.

SHORT TERM
(Thursday through Friday night)
Issued at 343 AM EDT Wed May 8 2024

The forecast Thursday afternoon and evening is fairly complex and contains an unusually high degree of uncertainty. HiRes CAMs have latched onto reinvigorating an MCS as it tracks across SE GA.
With the MCS arriving around the time of peak heating, instability will build to sufficient levels as deep shear increases to around to 30- 40 kts. These ingredients should support the chance for a few more intense storms that may reach severe limits and be capable of straight-line winds 50-60 mph, hail, and possibly an isolated tornado. Uncertainty is quite high as the MCS timing and track will be crucial to how far south the severe threat will extend. The SPC has extended the Slight Risk (Level 2 of 5) to the I-10 corridor and a Marginal risk farther south into north- central FL. The severe threat will wane Thursday evening as activity moves offshore.

After a brief lull in the storms Thursday night, a second MCS feature will push in from the west and is a bit slower in it's arrival compared to 24 hrs ago. Now this MCS appears to reach inland areas of SE GA and Suwannee Valley around daybreak Friday at the earliest, though there is still a fair amount of discrepancies regarding the timing. This will bring another potential for scattered strong to severe storms capable of all hazards once again. The cold front will finally push through Friday night and continue the chance for scattered storms across northeast and north-central FL through about midnight. Before the storms arrive in NE FL, tightening gradients will lead to breezy southwest winds during the afternoon with gusts around 25-30 mph south of I-10.

In addition to severe storm potential, hot temperatures with near triple-digit heat index values are expected Thursday before convection arrives. High temps will push into the mid 90s and challenge daily records across the region. Increasing cloud cover and the potential for storms earlier in the day will cap heating to to mid 80s in SE GA and upper 80s to 90 in NE FL on Friday.|

LONG TERM
(Saturday through Tuesday)
Issued at 343 AM EDT Wed May 8 2024

Cooling temps and lowering humidity will lead to comfortable conditions this weekend as high pressure builds from the north. A wet, stormy and unsettled weather returns again next week as southerly flow attempts to lift the old frontal boundary northward. As it does so, several shortwave disturbance are expected to lift across the region leading to scattered to numerous showers and storms Monday through Wednesday. Temperatures will trend cooler but hover near normal through the weekend. Next week temperature forecasts are much trickier as cloud cover and several waves of rain/storms appear likely. That said, heating should be hampered and diurnal ranges should be compressed, keeping afternoon highs below normal and lows above normal.

AVIATION
(12Z TAFS)
Issued at 629 AM EDT Wed May 8 2024

Southwest flow off the Gulf bringing in low cloud decks and MVFR/IFR fog at GNV/VQQ is expected to disperse before 13z. Winds will build from out of the SW this afternoon with the SE diurnal sea breeze remaining pinned close to the coast. Winds will become more mild for sites during the overnight hours and into early Thursday morning.

MARINE
Issued at 343 AM EDT Wed May 8 2024

High pressure ridge will continue to shift across the area through Thursday, with breezy south winds expected at times.
Offshore winds develop by Thursday night as a cold front approaches the region. Evening southerly wind surges may lead to cautionary conditions for small craft each night until the cold front arrives by Friday night. Offshore winds will increase Friday ahead of a frontal passage. Brief period of strong northerly winds possible in the wake of the front Friday night into Saturday.

Rip Currents: Moderate risk for area beaches through Thursday.

FIRE WEATHER
Issued at 343 AM EDT Wed May 8 2024

Isolated showers and perhaps a storm or two inspired by the sea breeze are possible this afternoon. After today, hotter and drier conditions prevail under a building ridge of high pressure Wednesday and Thursday before a late season cold front arrives Friday. Strengthening surface and transport winds from the southwest ahead of the front will build dispersion each day through Friday. High dispersions are expected areawide by Thursday and likely again Friday. A wetter pattern will kickoff with the frontal passage this weekend and should continue into next week.
