Some of these storms may contain strong gusty winds and heavy downpours. Westerly winds will turn southerly this afternoon due to the atlantic seabreeze and then become breezy from the north and northeast overnight into Monday as a secondary cold front pushes south of the waters and high pressure Wedges down from the mid atlantic coast against a low pressure over the western atlantic waters through early next week. High pressure builds directly over the waters during the middle part of next week.

...STRONG TO ISOLATED SEVERE THUNDERSTORMS WILL DEVELOP OVER THE AREA THIS AFTERNOON INTO EARLY EVENING...
NEAR TERM
Issued at 355 AM 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
A wave of showers and thunderstorms ahead of a slow moving, nearly stalled cold frontal boundary from the west has brought some late night and early morning rainfall to portions of eastern SE GA along and south of US highway 84 to areas over NE FL from Gainesville northeast to the Jax Beaches. These showers and storms will end by sunrise.
Cold front will stall near NE FL today with partly cloudy skies late this morning through afternoon and west to southwesterly winds 8-12 mph, a bit breezier across north central FL towards the Gulf coast 10-15 mph. Strong heating due to the high sun angle for mid to late May (nearly one month before the upcoming summer solstice) will raise high temperatures into the upper 80s with isolated 90 degree readings along the St Johns river basin and I-95 corridor over NE FL as the Atlantic seabreeze stays pinned near the immediate coast. A positively tilted mid level trough currently over northern GA will shift southeast into the area through this afternoon with shortwave energy rounding the base of the trough that will become closed with southeast extent. This will cool mid level lapse rates over the area with thunderstorms developing over north central Fl this afternoon with a secondary focus over SE GA north of Waycross late this afternoon that will move southeast into the Jacksonville area by around sunset and then shift off the NE FL coast before midnight. Dewpoints around 70 along the coast and upper 60s inland will create strong CAPE values over 2,000 J/KG while the closed trough will cool mid level temperatures to -11 to -13 C which will steepen mid level lapse rates. Strong 0-6km shear of 30-40 knots will also be present and the Storm Prediction Center has a Marginal threat of Isolated Severe T'storms for most of the area as the ingredients mentioned will support large Hail and isolated strong to severe wind gusts up to 60 mph. Not expected widespread heavy rainfall today, but pockets of 1 inch totals will occur closer to the coast where best focus for storms will be with a few higher isolated amounts to 2 inches possible.
Storms should exit into the Atlantic by midnight and the cold front will clear southeast of the area overnight with northerly to northeasterly winds winds turning northerly 5-10 mph inland and breezier at the coast 10-15 as high pressure builds down from the Mid Atlantic and northeast coastline. Low stratus clouds will sink south along the Southeast coast into SE GA with lows in the mid 60s over SE GA and the upper 60s over NE FL.
SHORT TERM
(Monday through Tuesday night)
Issued at 355 AM EDT Sun May 19 2024
Upper trough will move over forecast area Monday, then gradually shift just S of forecast area Monday night, continuing further S Tuesday. Latest consensus guidance suggests continued potential for scattered showers/ t-storms Monday with onshore flow pattern.
Guidance suggests showers mainly offshore Monday night, but potential for coastal showers moving onshore ne FL Tuesday with continued onshore flow.
Onshore flow pattern will result in somewhat lower high temperatures eastern counties with upper 70s/lower 80s coast and I-95 corridor, a little warmer further inland.
LONG TERM
(Wednesday through Saturday)
Issued at 355 AM EDT Sun May 19 2024
Upper ridge of high pressure will build over the forecast area during this period, resulting in mainly dry and warm conditions.
An exception could be on Saturday when a weak shortwave passes over the area, which consensus guidance suggests could lead to scattered showers/t-storms. Near normal temperatures are expected on Wednesday, with highs lower 80s coast, mid-upper 80s inland.
Slightly above normal temperatures are expected Thursday through Saturday with high temperatures upper 80s coast, lower 90s inland ...with low temperatures through the period in the 65-70 range.
AVIATION
(06Z TAFS)
Issued at 152 AM EDT Sun May 19 2024
A round of showers and embedded thunderstorms streaming in from the Gulf of Mexico will press east through SSI, GNV, VQQ, JAX, and CRG over the next 3 hours, ending by 09Z with VCSH posted for a couple of hours before showers end early this morning. Ceilings will be MVFR around 2.0 kft through sunrise during and in the wake of the showers and thunderstorms with variable light winds as the storms will be elevated.
Another round of showers and thunderstorms will commence late this afternoon as the cold front stall over northeast florida before a secondary cold front swings south from the Georgia coast with strong thunderstorms that may produce gusty winds to 30 knots and MVFR restrictions after 20Z for SSI and duval terminals and around 00Z for SGJ while GNV coverage should remain VCTS through sunset.
WInds this afternoon will be west to west southwesterly with southerly winds at SSI and SGJ this afternoon from the pinned Atlantic seabreeze, then winds shift this evening after 00Z to north and northwest in the wake of the secondary cold front with showers and storms ending after 03-04Z for all sites with lingering mid level clouds and scattered low ceilings. Confidence too low in MVFR ceilings to end the 06Z TAF period.
