The episode as NWS JAX wrote it up.
A fast moving pre-frontal squall line with isolated thunderstorms moved across northeast Florida during the morning. Instability was limited, but a strong low level jet of 50-60 knots between 1-1.5 kft produced isolated wind damage in thunderstorm activity.
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 Dec 26, 3:15 AM EST, 5 hours 25 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
315 AM EST WED DEC 26 2012
...SLIGHT RISK OF SEVERE WEATHER TODAY...
.SHORT TERM (WED-FRI)...PROGRESSIVE PATTERN CONTINUES ACROSS THE
U.S. WITH ACTIVE SOUTHERN STREAM FROM THE SW TO SE U.S. MAIN
CONCERN FOR THE SHORT TERM IS A DEEPENING STORM SYSTEM ACROSS
SOUTH CENTRAL TENN WITH A PRE-FRONTAL SQUALL LINE EXTENDING
FROM THE EASTERN FL PANHANDLE AND BEGINNING TO MOVE INTO
EXTREME SW GA. STORM SYSTEM RACES NE TODAY AND SQUALL LINE
PUSHES THROUGH THE REGION THIS MORNING AND THEN MOVES OFFSHORE
THIS AFTERNOON AND EVE. USED A BLEND OF THE GFS AND NAM FOR TIMING
OF SQUALL LINE AND HAVE IT MOVING THROUGH SE GA AND UPPER SUWANNEE
VALLEY REGION AT AROUND DAWN...THE REST OF NE FL DURING MID
MORNING...AND THE FAR SE ZONES LATE MORNING INTO EARLY AFTERNOON.
JET DYNAMICS ARE STRONG BUT INSTABILITY IS WEAK. ALSO...AS THE
STORM SYSTEM MOVES NE...A LOT OF THE STRONG LIFT AND DYNAMICS
WILL ALSO LIFT TO THE NORTH OF THE AREA. SPC DOES CONTINUE TO
HAVE A SLIGHT RISK OF SEVERE WX WITH DAMAGING WINDS AND ISOLATED
TORNADOES. THE MAIN CONCERN IS THAT THE WEAK INSTABILITY MAY BE
SUFFICIENT ENOUGH FOR A FEW OF THE STORMS TO BECOME SEVERE WITH
DAMAGING WINDS AND POSSIBLY BRIEF SPIN UPS. TIGHT PRESSURE GRADIENT
WITH APPROACH OF COLD FRONT WARRANTS A CONTINUATION OF CURRENT
LAKE WIND ADVISORY THROUGH EARLY THIS EVE. CLOUDS/POPS RAPIDLY
DECREASE LATE THIS AFTERNOON AND EVE AS DRY SLOT AND COLD FRONT
MOVES INTO THE AREA. HIGH PRESSURE WILL BUILD IN BEHIND SYSTEM
THU-FR BRINGING IN A COOLER AND DRIER AIR MASS. NO WIDESPREAD
FREEZES ARE EXPECTED BUT WILL PROBABLY HAVE PATCHY FROST ACROSS THE
INLAND AREAS THURSDAY NIGHT.
.LONG TERM (FRI NIGHT-TUE)...
FRIDAY NIGHT/SAT...LOW PRESSURE IS EXPECTED TO MOVE ACROSS THE GULF
COAST WITH ENOUGH LIFT IN ADVANCE OF IT FOR NUMEROUS SHOWERS AREA
WIDE...WITH A FEW EMBEDDED TSTMS ACROSS NE FL.
SAT NIGHT-MON...THE COLD FRONT WILL PUSH THROUGH SAT NIGHT WITH HIGH
PRESSURE BUILDING IN BEHIND THE FRONT. TEMPS WILL BE NEAR NORMAL
EARLY THEN RISE TO SLIGHTLY ABOVE NORMAL TUE AS THE AIR MASS
MODIFIES. NO FREEZES ARE EXPECTED.
TUE...THE GFS TRACKS A LOW IN FROM THE GULF ACROSS GA WHEREAS
THE ECMWF KEEPS CONDITIONS DRY. WILL PUT IN LOW POPS FOR GA
FOR NOW. TEMPS AVERAGING SLIGHTLY ABOVE NORMAL.
&&
.AVIATION...
VFR CONDS CONTINUE THIS MORNING WITH RAPID DECREASE TO MVFR/IFR
VSBYS/CIGS WITH THE SQUALL LINE AND TIMING STILL EXPECTED IN THE
14-17Z RANGE. HAVE KEPT WORDING OF VRB30G45KT IN THE CURRENT TAF
SUITE FOR SQUALL LINE ALTHOUGH IT MAY END UP BEING WORST CASE
SCENARIO BASED ON CURRENT TRENDS. AFTER 18Z...TAF LOCATIONS SHOULD
SEE GUSTY SW WINDS CONTINUE BUT VFR CONDS RETURN WITH JUST HIGH
CLOUDS REMAINING. AFTER 00Z WINDS WILL START TO WEAKEN WITH WLY
WINDS AT 10-15 KNOTS THROUGH THE EVENING HOURS.
&&
.MARINE...
FREQUENT GUSTS TO GALE FORCE STILL EXPECTED WITH STRONG S/SW FLOW
TODAY WITH PEAK GUSTS IN THE 40-45 KNOT RANGE...STRONGEST EXPECTED
RIGHT ALONG THE SQUALL LINE. HEADLINES WILL REMAIN INTACT THROUGH
TONIGHT WHEN DECREASING WINDS/SEAS TREND DEVELOPS. HIGH PRESSURE
BUILDS IN ON THU/FRI WITH LIGHTER WINDS/SEAS DEVELOPING. NEXT LOW
PRESSURE SYSTEM TO DEVELOP IN GOMEX FRI NIGHT THEN TRACK ACROSS THE
WATERS ON SATURDAY WITH NEXT SMALL CRAFT ADVISORY EVENT WITH STRONG
NORTH FLOW CONTINUING ON SUNDAY IN THE WAKE OF LOW PRESSURE.
RIP CURRENTS: LOW RISK WITH THE OFFSHORE FLOW.
&&
.FIRE WEATHER...
HIGH PRESSURE AND DRIER AIRMASS WILL ALLOW FOR MIN RH VALUES INTO
THE 30-35% RANGE ACROSS NE FL ON THU/FRI AFTERNOONS BUT WITH LIGHTER
WINDS AND MOIST GROUND CONDITIONS...DO NOT EXPECT ANY RED FLAG
HEADLINES.
