The episode as NWS JAX wrote it up.
A tight pressure gradient was over southeast Georgia and northeast Florida early Thursday morning through afternoon due to high pressure to the east and an approaching squall line to the west. A low level jet ahead of the front also moved across inland southeast Georgia Thursday morning into early afternoon. The combination of a tight gradient and a low level jet produced gusty winds ahead of the squall line. A Wind Advisory was in effect for all of southeast Georgia and northeast Florida. A tree fell across a road in Jeff Davis county. Wind gusts between 40 and 50 mph were observed across the area through the day ahead of the squall line.

Area Forecast Discussion
National Weather Service Jacksonville FL
307 AM EDT Thu Mar 31 2022
...ISOLATED TO SCATTERED SEVERE STORMS TODAY...
.NEAR TERM [Through Tonight]...
Cirrus cloud cover will continue to overspread and thicken across
the area downstream of a squall line that was traversing the FL
panhandle and southeast AL/southwest GA. Breezy southerly winds
have remained overnight due to a tight pressure gradient.
Temperatures this morning were warm in the mid 60s to lower 70s,
which were 10-20 degrees above normal.
A jet streak along the northern Gulf coast will pivot northeastward
across the Deep South today, becoming aligned across the
Carolinas and the Mid-Atlantic coast by late tonight and Friday
morning. This feature will strengthen diffluent west-
southwesterly flow aloft across the region as a potent shortwave
trough pivots eastward across the Southern Plains states and then
pushes east northeastward across the lower Mississippi and
Tennessee Valleys this afternoon and evening. The local pressure
gradient will tighten further this morning ahead of the squall
line, and a Wind Advisory is in effect across the entire area
through the late afternoon hour with south southwesterly wind
gusts of 35 to 45 mph expected.
Model soundings indicate that a 50-60 knot low level jet at 850
millibars (around 5,000 feet) will traverse inland southeast GA
this morning and early afternoon, which will increase the threat
for severe weather for locations from the northern Suwannee Valley
northward across inland southeast GA. Damaging wind gusts of
50-70 mph and isolated tornadoes will be the primary threats
through early afternoon. The squall line should then become broken
as it approaches the I-95 corridor during the afternoon hours,
but ML CAPE values increasing to around 1,500 j/kg will keep a
threat of strong to isolated severe thunderstorms in place through
late afternoon. Rainfall amounts around 1 inch are expected, with
locally higher amounts possible. Highs will soar to the mid and
upper 80s along the I-95 corridor, while the earlier arrival of
the squall line keeps highs in the mid to upper 70s across inland
southeast GA and the northern Suwannee Valley.
The frontal boundary will slow down as it moves across northeast
Florida tonight, moving into central Florida by Friday morning.
Scattered showers and isolated storms will continue overnight
from a line south of St. Augustine to Gainesville. Cooler air will
move in behind the front, with overnight lows in the low to mid
50s across interior southeast Georgia and the Suwannee Valley,
near 60 to the lower 60s across coastal southeast Georgia and
much of interior northeast Florida, and the mid to upper 60s south
and southwest of St. Augustine.
.SHORT TERM [Friday Through Saturday]...
The frontal boundary will stall just to the south of the forecast
area on Friday with reduced chances for precipitation over the
southernmost portion of the forecast area for the end of the week.
A passing upper level shortwave may lead to increased chances for
showers and possible thunderstorms, primarily over northeast
Florida, this weekend as upper level shortwaves move through the
eastern US. High temperatures for this period will be in the upper
70s and lower 80s with overnight low temperatures dropping down
into the 40s and 50s.
.LONG TERM [Sunday Through Thursday]...
Drier weather associated with high pressure conditions will be in
place on Sunday and Monday with high pressure moving off to the
east leading to a shift in the prevailing flow shifting from out
of the west and northwest to a more moist flow from out of the
southwest by Tuesday, resulting in another bout of showers and
thunderstorms moving through the region by midweek. Temperatures
will go through a gradual warming trend thru midweek, with high
temperatures rising into the mid to upper 80s by Wednesday.
&&
.AVIATION...
[Through 06Z Friday]
Southerly winds around 10 knots with higher gusts will continue
the rest of the night. Wind shear is possible at the TAF sites
through this morning due a strong low level jet. Southerly winds
will increase to 15-25 knots with higher gusts by the late morning
hours. A squall line will move into the area this morning, and
then impact the TAF sites this afternoon. Rain is expected to end
this evening, with ceilings lowering to low MVFR overnight. Winds
will diminish to 10 knots or less overnight.
&&
.MARINE...
Gale Warning remains in effect for the offshore waters through
this evening for frequent gale force gusts. A Small Craft Advisory
continues through this evening for the nearshore waters, and a few
gusts to gale force are possible. A Small Craft Advisory will be
in effect tonight for the offshore waters for seas 5-7 feet and
winds around 20 knots.
Rip Currents: High Risk of Rip currents for all of the beaches
of NE FL and SE GA today. A Moderate Risk of rip currents is
expected for all of the regional beaches on Friday.
&&
.FIRE WEATHER...
High daytime dispersion values today. Low dispersion values over
the Suwannee Valley region on Friday. Showers and thunderstorms
will move across the forecast area today, with the squall line
expected to reach SE GA in the morning and NE FL in the afternoon,
with the front reaching north central Florida in the late
afternoon and evening hours. Gusty winds will build today from out
of the SW with speeds reaching up to 20-25 mph with gusts of
35-45 mph possible. Winds will become more calm on Friday and
shift about to be out of the NW as the cold air mass settles in
over the region after the frontal passage.
