A pre-frontal squall line moved across the local area during the pre-dawn hours. Dynamical forcing was strong including deep layer shear and low level helicity values supportive of strong downburst wind and isolated tornadoes, but instability was overall lacking across the local area to support a widespread severe storm threat.

The episode as NWS JAX wrote it up.
A pre-frontal squall line moved across the local area during the pre-dawn hours. Dynamical forcing was strong including deep layer shear and low level helicity values supportive of strong downburst wind and isolated tornadoes, but instability was overall lacking across the local area to support a widespread severe storm threat. A nose of instability just ahead of the squall line edged inland across portions of the Suwannee River Valley during the early morning hours, which phased with stronger dynamics with the squall lien and produced a few strong to severe storms.
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 Nov 30, 2:03 AM EST, 2 hours 27 minutes earlier.
Area Forecast Discussion
National Weather Service Jacksonville FL
203 AM EST Mon Nov 30 2020
.Near Term...[through Tonight]...
Strong cold front will move east southeast across the region this
morning. Expect it to be east of the area by noon. Continued
potential for strong wind gusts in storms ahead of and along the
boundary, and can not rule out potential for an isolated tornado
due to shear and frontal convergence. Clearing will follow the
front, but wrap around moisture is expected to pivot across SE GA.
The combination of the cloud cover and cold advection will cause
temperatures to fall through the afternoon across SE GA, whereas
the sunshine should help keep temperatures fairly steady through
much of the day time hours over NE FL. In general, highs Today
will be recorded this morning. It will also be fairly breezy
Today.
For Tonight, skies will clear from the northwest, with high pressure
building from the west. The gradient will remain fairly tight
through the night, so winds will continue to stir overnight. The
winds will minimize frost formation despite lows in the 30s.
Low temperatures near or at freezing possible well inland, but
not expecting to be at or below 32 long enough to warrant a freeze
warning at this point.
&&
.SHORT TERM [Tuesday through Wednesday Night]...
...WIDESPREAD INLAND LIGHT FREEZE EVENT EXPECTED TUESDAY NIGHT...
Tuesday...Sunny skies and cold conditions as Meteorological Winter
begins on 12/1 and gusty Northwest winds continue at 15-20 mph
with gusts of 25-30 mph and strong cold air advection will hold
Max Temps around 50 degrees across SE GA and lower/middle 50s for
NE FL.
Tuesday Night...As cold high pressure settles over the region
expect NW winds to decrease to less than 5 mph and along with
mostly clear skies will set up good radiational cooling
conditions and a widespread light freeze is expected over all
inland areas, with lows in the upper 20s across SE GA and near
30 degrees across inland NE FL and Freeze headlines will likely
be required. Some light frost will be possible as well by early
Wednesday morning as winds become near calm in wind sheltered
areas.
Wednesday...High pressure continues to push Northeast of the
region and surface winds become light Northeast and under
Mostly Sunny skies Max Temps will modify slightly into the
middle 50s SE GA and upper 50s/near 60 degrees across NE FL.
Upper level cloud cover increases Wed Night but another night
of widespread low temps in the 30s possible over inland areas
and 40s along the Atlc Coast and another brief light freeze
not out of the question for inland SE GA areas near the
Altamaha River Basin.
&&
.LONG TERM [Thursday Through Sunday]...
Thursday...Mainly dry conditions with increasing high clouds
ahead of next frontal system and expect milder temps with the
onshore flow off the Atlantic as Sfc High pressure builds into
the Carolinas. Max Temps into the 60s across SE GA and near 70
across NE FL.
Friday...Long-range models have backed off the intensity of
next shortwave trof energy/moisture available and now rainfall
chances are mainly in the 20-40% range with the next frontal
passage. Max Temps will likely reach into the 70-75 degree
range and lows falling into the 40s/50s Fri Night.
Sat/Sun...Models struggling to handle the expected mid level
cut-off low feature to push across the SE US over the weekend,
but for now it appears as though it will not phase with moisture
over the Gulf of Mexico and cross the NE FL/SE GA region with
mainly dry conditions and seasonably cool temps with Highs in the
60s and lows in the 40s, but confidence remains low in the model
solutions from the Friday through Sunday time frame.
&&
.FIRE WEATHER...
On Tuesday, much colder and drier airmass will combine with gusty
Northwest winds and humidity values falling into the 30 to 35
percent range to provide for more hazardous fire weather
conditions but for now expect values to stay just above critical
levels.
&&
.Marine...
A strong cold front will move east across area this morning. High
pressure will build from the west this afternoon through Tonight.
The high will build overhead Tuesday through Tuesday night. The high
will then build toward the northeast Wednesday through Thursday. A
wave of low pressure will move northeast out of the gulf, and across
area Thursday night through Friday. The region will be between low
pressure to the northeast and high pressure building from the west
over the weekend.
Rip Currents: SE GA: Moderate through Tuesday
NE FL: Moderate through Tuesday
