The episode as NWS JAX wrote it up.
Inverted surface trough lifted slowly across north Florida as the area was under the base of a mid/upper level trough axis. An anomalously moist airmass (PWATs near 2.2 inches) remained over the area. The sea breezes developed and slowly shifted inland through the day before colliding near the I-75 corridor in the evening. Weak steering flow, abundant tropical moisture, and forcing from the trough helped bring over 3 inches of rain to Suwannee county falling within 90 minutes.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Jacksonville, FL wrote its last area forecast discussion before the first event at Aug 29, 6:55 PM EST, 1 hour 20 minutes earlier.

.NEAR TERM...
(Through Tuesday)
Issued at 340 PM EDT Mon Aug 29 2022
Surface high pressure will be east northeast of the region this
afternoon into Tonight. An inverted trough is expected to develop
over the northeastern Gulf this evening, which will extend northeast
across the region Tonight into Tuesday morning. The moist airmass
remains in place. The flow at the surface is light from the east,
with a light southerly flow at the mid levels. Due to the light
flow, showers and storms will move slowly again this afternoon and
evening, with only a gradual inland push from the Atlantic sea
breeze. The development of the inverted trough will cause convective
activity to hang on a little longer this evening, and re develop a
little earlier Tuesday morning.
The high will build more to the east Tuesday afternoon. The surface
flow will be from the south Tuesday, continuing to bring ample
moisture into region. Numerous showers with embedded thunderstorms
anticipated once again Tuesday afternoon and evening.
Flood Watch in place across portions of NE FL will continue through
Tonight, as this area has become fairly saturated by recent rains,
so flooding potential is heightened. This Watch may need to be
expanded/extended Tonight depending on coverage and intensity
of Todays activity.
Patchy fog will be possible toward dawn, especially in areas that
receive heavy rains this afternoon and evening.
Temperatures this period will be near seasonal levels.

.SHORT TERM...
(Tuesday night through Friday)
Issued at 340 PM EDT Mon Aug 29 2022
High pressure will build more toward the southeast Tuesday night
into Wednesday, as a cold front slides into the southeastern US.
This front will then stall through the Carolinas into Southern GA
through Thursday. Moisture will remain in place across the region
this period, with this front providing a source of convergence to
enhance daily potential for showers and storms.
The front will dissipate into Thursday night, with high pressure
building to the northeast Friday. Friday will again be a wet day,
but with the flow becoming more onshore the best chance for showers
and storms will move inland through the afternoon.
Temperatures this period will trend near to a little above normal.
&&
.LONG TERM...
(Friday night through next Monday)
Issued at 340 PM EDT Mon Aug 29 2022
High pressure will be northeast of the region through Saturday.
With this pattern the onshore flow will continue. While
precipitation chances will be above seasonal levels across the area,
the greatest chance will be inland due to the sea breeze and onshore
flow.
The high is expected to move more toward the north Sunday into
Monday, as potential tropical system may be over western Atlantic.
There is a great deal of uncertainty as to movement and strength of
this low though at this time. With high more toward the north, the
flow over region will trend more from the northeast helping to focus
greatest diurnal convective chances over inland NE FL counties.
Temperatures will trend near normal this period.
