Another day with a mix of sun and clouds is underway as the east coast seabreeze progresses further inland. The breeze is getting hung up a bit near the St. Johns River breezes and building some taller cumulus, though just not quite enough layer moisture for any showers or storms to come out of this as of now. A few isolated showers cannot be ruled out between about I-75 and I-95 through the next few hours, though the main focus area will be in the vicinity of and west of I-75 and into southwestern GA counties this evening where the sea breeze collides with the Gulf breeze.
There is also a surge of higher PWATs further west ahead of a shortwave impulse aloft, which should also aid in the formation of some showers and a few t'storms. Not expecting anything at severe criteria, as instability will not be significant and the flow aloft is generally weak. Most areas have risen into the mid to upper 80s, with maybe just a few degrees more to rise inland before the arrival of the sea breeze. Closer to the coast, likely have already topped out in the low 80s.
The aforementioned shortwave pushes closer overnight tonight, which will be enough for some showers and isolated t'storms to persist overnight. Especially in areas inland to the west and north of I-10, away from strongest surface ridging and where there will be greater available moisture. With the lingering convection overnight and more cloud cover in the area, not expecting as much in the way of fog Saturday Morning as compared to this morning.
Though some patchy areas cannot be ruled out, especially over northeast FL. Lows will be mild, in the 60s to low 70s by the coast.
SHORT TERM
(Saturday through Sunday night)
Issued at 219 PM EDT Fri May 3 2024
Saturday...Rather messy/complex forecast as mid level trough/surface frontal boundary over the SE US and any ongoing leftover convection across inland SE GA and the Suwannee River Valley during the morning hours with abundant clouds will disrupt the usual diurnal sea breeze convective cycle. This will lead to unbalanced afternoon scattered to numerous showers and storms along both leftover boundaries over inland areas and weaker than normal inland moving sea breeze fronts from both the Gulf/Atlantic, which should still lead to decent afternoon/evening convective coverage, mainly over inland areas, but timing and strength of any convection will depend on how much insolation occurs through the daytime hours. Models have trended slightly downward with Max temps in the lower/middle 80s across SE GA and along the Atlantic Coast, while mid/upper 80s still expected over inland NE FL south of the I-10 corridor where the most sun is expected through the day and will likely be the location for any of the isolated stronger storms with gusty winds 40-50mph, lightning and heavy downpours, but widespread severe storms are not expected at this time.
Saturday Night...Mid level trough aloft is expected to weaken with a more normal downward diurnal trend in convection after sunset, with more quiet conditions expected during the overnight hours under fair skies. Low temps expected in the mid/upper 60s inland, with lower 70s along the Atlantic Coast. Some patchy fog is possible inland but will depend on amount/coverage of rainfall on Saturday and potential clearing skies during the overnight hours, so have not included in forecast/grids this far in advance.
Sunday...Lingering moisture from decaying trough aloft and more normal diurnal sea breeze circulation should lead to scattered afternoon storms, which may be numerous where sea breeze activity meets between the I-75 and US 301 corridors over inland areas, along with continued potential for widely scattered strong storms with gusty winds to 50 mph, small hail, lightning and heavy downpours. Max temps expected to reach the widespread upper 80s with isolated near 90 degree readings over inland areas, while the Atlantic Coast tops out in the lower/middle 80s.
Sunday Night...Weak ridging aloft begins to build into the region and expect an earlier end to most diurnal convection by sunset with partly/mostly clear skies developing overnight with lows in the mid/upper 60s inland and lower 70s along the Atlantic Coast.
Typical patchy fog possible over inland areas, but significant dense fog not expected at this time.
LONG TERM
(Monday through next Friday)
Issued at 219 PM EDT Fri May 3 2024
Monday...Weak mid level trough passage through the SE US region and associated lingering moisture should continue the early summer-like sea breeze convective pattern with scattered to numerous showers and storms by the afternoon hours, with best chances across inland SE GA where deepest moisture remains. Max temps generally in the upper 80s/near 90 over inland areas, with lower/middle 80s along the Atlantic Coast and the threat for widely scattered strong storms will continue.
Tuesday through Friday...Not much change to the ongoing forecast of hot and mainly dry weather still on track as mid level ridging builds into the Gulf of Mexico and surface ridge axis builds south of the local region and this will trap the East Coast sea breeze along the Atlantic beaches and build the daytime highs into the lower to middle 90s with near record highs possible in the Wednesday through Friday time frame. Diurnal convection will be suppressed but isolated storms will still be possible on Tuesday, and again by the late Friday time frame as some long range models are pushing a frontal boundary into the local region by the following weekend. Dew points mixing down into the mid/upper 60s during the afternoon hours will keep the heat indices likely below any Heat Advisory levels, but peak Heat Indices into the 100-105 range will be possible in the Wednesday through Friday time frame.

VFR is currently prevailing at all sites. The east coast sea breeze will continue to progress inland through this evening, with a change in wind direction and speed for JAX/VQQ/GNV over the next few hours. Chances for any SHRA are very low (less than 10%) at area sites through this evening, with the best chance being at GNV. However, probability and confidence remains too low to include in the forecast. FG is expected to be limited Saturday Morning, though did include a tempo for reduced vis at VQQ.
