Majority of daytime convection has weaned, with the exception of a
few showers south of the Okefenokee Swap, one of which has
produced a few lightning strikes. Expect these showers to
dissipate over the next hour or so as they drift eastward.
Remnants of daytime convection could hold together over inland
southeast GA overnight as another weak shortwave passes overhead
aloft. Patchy to areas of fog will also be expected for some
inland areas, especially over far western FL and GA counties where
the most rain fell today.

https://www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf

Early to mid morning convection and cloud cover that pushed across
the region has disrupted the usual diurnal convective cycle and
has delayed the onset of sea breeze circulations this afternoon,
but as enough partial sunshine pushes the temps into the 80s
through the remainder of the afternoon hours, expect a resurgence
of scattered to numerous showers and storms along old outflow
boundaries and inland moving sea breeze through the early evening
hours, with a few isolated strong storms possible over inland
areas with gusty winds, but the overall main impact will be some
locally heavy rainfall due to the slow storm movement and frequent
lightning in some of the activity. With the late start to
convection, expect activity to linger until around midnight as
weakening storms become lingering shower activity and drift back
towards the Atlantic Coast. Partly cloudy skies develop overnight
with patchy fog development over inland areas, with locally dense
fog possible where more significant rainfall fell today, most
likely across inland SE GA towards sunrise Sunday morning. Low
temps generally in the mid/upper 60s inland and lower 70s along
the Atlantic Coast.

.SHORT TERM...
(Sunday through Monday night)
Issued at 110 PM EDT Sat May 4 2024

Upper level high pressure ridge will build over the forecast area
Sunday. Latest guidance indicates potential for scattered to
numerous showers and t-storms along sea breezes during the
afternoon. A weak shortwave trough passes N of forecast area
Monday, leading to greater coverage of showers N of forecast area
extending S across our s-ctrl GA counties, with lesser coverage
further S. Temperatures during this period are expected to be
slightly above normal, with highs in the mid-upper 80s inland,
lower 80s immediate coast, with morning lows in the mid-upper 60s
inland, near 70 coast.

&&

.LONG TERM...
(Tuesday through next Saturday)
Issued at 110 PM EDT Sat May 4 2024

A more substantial upper ridge builds over the forecast area
during this period in response to an intense storm system over
the central U.S. The latest guidance suggests this will be a drier
and warmer period for forecast area, with well-above normal
temperatures. By Wed-Fri, high temperatures will be in the lower-
mid 90s, with morning lows in the upper 60s to around 70. Late
Friday a cold front will move over s-ctrl GA introducing a chance
of showers with slightly cooler temperatures there.

.AVIATION...
(00Z TAFS)
Issued at 733 PM EDT Sat May 4 2024

VFR is prevailing at all terminals at this time. Lingering
convection remains generally between GNV and VQQ which will remain
near the general vicinity of these terminals over the next few
hours. However, only SHRA is currently expected with very low
chance of TSRA. Some fog/lower ceilings will likely develop
overnight and into Sunday morning, especially at more inland sites
at VQQ/JAX/GNV. Convection will be expected once again Sunday
afternoon, with confidence high enough for TS to include TSRA at
only JAX/VQQ/GNV at this time.

.MARINE...
Issued at 110 PM EDT Sat May 4 2024

High pressure will remain anchored northeast of the local waters
through the weekend. Afternoon sea breeze development will
continue each afternoon for the next several days as high pressure
re-positions further south, shifting winds toward a southerly
direction early next week. Winds should trend offshore toward the
end of next week as a cold front approaches from the northwest. No
headlines are expected through the period.

Rip Currents: Moderate risk of rip currents will continue through
early next week as local sea breezes dominate the surf zone with
breakers generally in the 1-2 ft range.
