Synopsis -
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.
Gulf stream -

East Coast/Gulf Coast sea breeze merger taking place along the US 17 corridor/St. Johns River Basin at the moment and just expect a few brief light showers/sprinkles through 10pm, otherwise skies becoming mostly clear for all NE FL/SE GA locations by the overnight hours. Low level SW flow will increase moisture enough to develop low clouds and patchy fog across inland NE FL, mainly along the I-75 corridor towards sunrise Wednesday morning. Lows generally in the upper 60s inland and lower 70s along the coast.
Mid level ridge axis holds in place across the region on Wednesday with enough subsidence to suppress convection for the most part and rainfall chances remain at 10% or less. The Southwest flow will pin the East Coast sea breeze to the I-95 corridor and the heat will build throughout the day reaching the middle 90s from the I-95 to US 301 corridors with Heat Indices (HI) peaking around 100 degrees, while the Atlantic Coastal Beaches should top out around 90 degrees.

Mostly dry conditions with only an isolated shower offshore near midday. The inland push of the sea breeze will be limited today as high pressure builds into the region, chances of isolated showers and storms will mainly be confined along the I-95 corridor in NE FL. Main threat concerns for any isolated t'storm would be occasional to frequent lightning, gusty winds, and brief heavy rainfall. By early evening, any shower/storm activity should clear out leading to skies becoming mostly clear across the area.
Patchy fog will be possible along the western edges of our area past midnight and clear out by sunrise. Overnight lows are expected to dip to the mid 60s over inland areas and in the low 70s along the coast.
SHORT TERM
(Wednesday through Thursday night)
Issued at 301 PM EDT Tue May 7 2024
The overall pattern Wed and Thu shows an upper level ridge across most of the forecast area and into the Gulf of Mexico, with some mid level troughing moving in Thursday afternoon, with the upper level ridge axis beginning to shift east of the area Thursday night. At the sfc, high pressure ridge is over the central FL peninsula and will move a bit southward by Thu to southern FL, as a cold front marches east to southeast from the TN and MS valley to Appalachians. The airmass will remain dry and hot for Wed and partly on Thu with 850 mb temps rising to about 19C and thicknesses that support mid 90s over the eastern zones. Hottest temps look to be over the eastern zones as the southwest winds, breezy at times, near 15 mph gusting to 25 mph, push the hot air all the way to the coast. In other words, the east coast sea breeze is going to be hard pressed to move inland, especially on Thursday. Heat indices likely to top out around 100-103 or so.
Record highs are possible. Not heat advisory criteria but if not used to heat since it's a bit early in the year for it, it will be sensitive to more vulnerable people or those working outdoors.
Models show a decent shot of some showers and storm coming in from the west, mainly affecting southeast GA, Thursday afternoon and night, with the ECMWF developing convection faster than the GFS. GFS eventually brings in a batch of showers and potential storms (MCS type feature) by early Friday morning. Latest trend in the GFS is for somewhat better chances of precip Thu night compared to prior runs. Latest forecast shows a slight uptick in chances
LONG TERM
(Friday through next Tuesday)
Issued at 301 PM EDT Tue May 7 2024
Cold frontal boundary will sag southward over the region Friday as mid to upper level trough moves through the region. Uncertainty on how things evolve early Friday and through the afternoon.
Current forecast shows showers and storms widespread over the north half of the area and more scattered to numerous further south. Latest model output suggests we may need to shift the higher POPs further south into northeast FL but will wait on further model agreement. The mid level trough moves east of the area by Friday evening and helps to push the cold front through our forecast area. Lingering precip will be possible Friday evening but the front should end up over central FL late Friday night into Saturday morning. Drier and cooler conditions Saturday and Sunday with the front well to the south and weak high pressure around 1016 mb over the TN valley. The southern stream flow is progressive so we expect the sfc high pressure to work northeast of the area Sunday night, and on Monday we see low pressure developing along a frontal boundary over the western Gulf of Mexico, and a warm front lifting up over parts of the north Gulf of Mexico. Thus, we ramp up rain chances again Monday from southwest to northeast, especially going into Monday night as well. Temperatures generally trend downward and fall below normal through at least Monday before warming up once again.
AVIATION
(00Z TAFS)
Issued at 713 PM EDT Tue May 7 2024
Isolated convection still possible along the NE FL Coastal Counties through 02Z, so have kept VCSH at JAX/CRG/VQQ/SGJ for now with the low chances of a brief shower. VFR conds through the evening then SW flow off the NE Gulf will provide enough moisture for low clouds (LIFR CIGS) and some MVFR/IFR fog at GNV/VQQ in the 08-12Z time frame, with lower chances at the other TAF sites.
Conds VFR after sunrise on Wednesday at all TAF sites with SW winds increasing to 10G15 knots, while SE sea breeze expected at 12G18 knots at SSI/SGJ during the afternoon hours.
