Forecast on track for more typical sea breeze t'storm activity this afternoon and evening as full sunshine this morning across NE FL/SE GA will push max temps into the upper 80s/near 90 over inland areas and lower/middle 80s at the Atlantic beaches. This heating will push East Coast sea breeze inland to merge with the Gulf Coast sea breeze across inland NE FL and with PWATs around 1.5 inches, we should see scattered showers/storms this afternoon over most areas with numerous showers/storms over portions of inland NE FL where merger takes place. Slow and erratic storm motion around 10 mph or less will lead to locally heavy rainfall as the main storm impact, but still expect a few strong storms with gusty winds to 50 mph, hail and frequent lightning over inland areas where mergers take place. Activity will fade after sunset and end by midnight with fair skies overnight with lows in the mid/upper 60s inland and lower 70s along the coast with patchy fog in some inland locations by sunrise Monday morning.

NEAR TERM
(Today and Tonight)

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

Current satellite imagery indicates gradually dispersing leftover cloud cover from last evening's convection. Once this cloud cover erodes and shifts east, areas of fog area likely to develop across interior regions of southeast GA, generally northwestward from Waycross. This region will be closely monitored for a Dense Fog headlines through the morning.

Stagnant low level ridging remains dominant today with very light southerly flow. Strong daytime heating will promote sea breezes from both coasts to march inland this afternoon. Diurnal instability should support scattered showers and thunderstorms along each respective sea breeze front through the afternoon hours. Increasing coverage likely along the I-75 corridor during the early evening as sea breezes collide. The overall threat for significant convection is fairly low given marginal lapse rates aloft and unimpressive flow throughout the column. The primary impact today will be the potential for localized, most likely nuisance, flooding from slow and chaotic storm motions along the sea breeze merger. HRRR guidance does indicate pockets of 2-3" amounts sprinkled along a line from Ocala FL northward to Folkston GA.

Tonight, convection will wane after sunset and fizzle out completely before midnight with associated debris clouds slowly fading afterward. This will set the stage for another night of patchy, and potentially areas, of inland fog again Sunday night and early Monday morning.

Temps will rise quickly under mostly sunny conditions this morning, reaching the upper 80s across the area today. Little change in the dewpoints, keeping lows generally in the mid/upper 60s once again tonight.

SHORT TERM
(Monday through Tuesday night)

A weak shortwave will pass over the region on Monday leading to increased chances for showers and storms for the beginning of the week with convection becoming more inhibited by Tuesday as high pressure ridging increases over the forecast area. Storm developments will be more numerous along the diurnal sea breeze boundaries and along areas of convergence. Temperatures will experience a warming trend next week with max temps rising into the lower 90s by Tuesday with overnight low temperatures dropping down into the mid 60s over inland areas and in the upper 60s and lower 70s along the coast.

LONG TERM
(Wednesday through Saturday)

Predominantly dry weather through the rest of the week as high pressure ridging strengthens over the region. Potential for convection will increase by the end of the week ahead of an approaching cold front pressing in from out of the west.
Temperatures will rise into the mid 90s as the week progresses with temps potentially reaching record seasonal levels before the weekend.

AVIATION
(12Z TAFS)
Issued at 640 AM EDT Sun May 5 2024

More normal sea breeze activity expected today with morning sunshine and VFR conditions which will bring in East Coast sea breeze past coastal TAF sites and will continue brief TEMPO groups during the afternoon hours 19-23Z at JAX/VQQ/GNV for MVFR TSRA activity with possible gusty winds to 25 knots. Activity ends by sunset (00Z) then mainly VFR overnight with the usual patchy MVFR fog at VQQ after 06Z.

MARINE

High pressure will remain anchored northeast of the local waters through Monday allowing afternoon sea breeze development each day. As high pressure repositions further south Tuesday, winds trend southerly and then turn offshore toward as the ridge axis slides farther south toward the end of the upcoming week. Offshore winds will increase Friday ahead of a frontal passage Friday night into Saturday.

Rip Currents: Low risk at area beaches today with surf around 1-2 feet. Risk will increase to Moderate as surf grows to about 2-3 feet on Monday.
