The episode as NWS JAX wrote it up.
A nearly stationary front meandered over NE FL with very high atmospheric moisture with PWATs 2.3-2.6 inches. This forcing and moisture combined with passing short wave troughs aloft and weak mesolows created isolated stronger storms with gusty winds and waves of very heavy, locally flooding rainfall.

Issued at 216 PM EDT Fri Sep 6 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
Numerous showers and embedded thunderstorms will move across
mainly southeast Georgia this afternoon, with coverage later this
evening focusing from the Gulf towards north central Florida to
the Atlantic coast. A bulk of the convection will simmer down
after sunset, although lingering activity is likely through the
night, mainly north of I-10. Confidence in flooding potential
remains the same, with coastal southeast Georgia highlighted as
the main area of concern through this evening. The Flood Watch is
in effect through early Saturday morning, although may be expanded
in time overnight depending on how this evening plays out.
Tonight, north and west of Waycross lows will fall into the upper
60s, with lower to mid 70s elsewhere. As winds calm overnight,
patchy fog will be possible near the I-75 corridor in Marion and
Alachua counties overnight, and where locally heavy rain falls
today.
&&
.SHORT TERM...
(Saturday through Sunday night)
Issued at 216 PM EDT Fri Sep 6 2024
A frontal zone will stretch west to east across northern FL through
Saturday night, with this front moving into central FL Sunday into
Sunday night.
The frontal zone will be the focus for continued rounds of showers
and thunderstorms through the weekend, with a higher than normal
chance for precipitation continuing. The potential will continue for
periods of heavy rainfall with localized flooding. The chance for
severe storms is low, but a few strong storms will be possible.
With the continued cloud cover and position of the frontal zone, day
time temperatures will continue to trend below normal. Lows will
range from a seasonal lower to mid 70s across NE FL, closer to the
frontal zone, to a below normal mid to upper 60s north of the front
across SE GA.
&&
.LONG TERM...
(Monday through next Friday)
Issued at 216 PM EDT Fri Sep 6 2024
The frontal zone will remain stalled over central to southern FL
this period, with high pressure to the north. The proximity of the
frontal zone, along with a moist onshore flow will keep
precipitation chances above seasonal averages.
It is possible with the strengthening onshore flow between the front
and the high, that inverted troughs could develop over the coastal
waters. These troughs would then increase convergence for shower
formation, in addition to adding to gusty wind potential at the
coast.
&&
.AVIATION...(18Z TAFS)
Issued at 201 PM EDT Fri Sep 6 2024
Convection beginning to initiate across north-central FL and TSRA
impacts more likely across KSGJ, KGNV and KSSI. There is less
confidence in TSRA development at the JAX metro airfields but it
cannot be ruled out if cloud cover continues to breakup.
Otherwise, MVFR conditions continue along the stalled front and
degrade to IFR tonight as ceilings lower through the predawn
hours. Passing disturbances will keep shower chances overnight,
but left as vicinity for now. Anticipate ceiling improvements
around 14z Saturday. Winds will remain light (at or below 10 kts)
and favor a W to NW direction.
&&
.MARINE...
Issued at 216 PM EDT Fri Sep 6 2024
A frontal boundary will remain mostly stationary across the
northeast Florida waters through Saturday, with periods of heavy
showers and embedded thunderstorms expected over area waters. A
cold front will then enter the southeast states on Saturday,
pushing across the Georgia waters on Sunday and then stalling near
or just south of the northeast Florida waters by Monday and
Tuesday. High pressure will strengthen over the Mid-Atlantic
region in the wake of this frontal passage early next week,
resulting in strengthening onshore winds and building seas.
Rip Currents: High rip current risk continues through tonight for
NE FL and SE GA beaches, with a moderate risk expected this
weekend.
&&
.HYDROLOGY...
Issued at 216 PM EDT Fri Sep 6 2024
Recent heavy rainfall has saturated grounds and created elevated
stream flow across coastal southeast Georgia and portions of
northeast Florida (Duval and Nassau counties). Bands of heavy
rainfall are expected through tonight which will exacerbate the
flood threat in these areas.
