What happened

The episode as NWS JAX wrote it up.

A line of showers and thunderstorms moved inland from the Gulf of Mexico during the afternoon and evening hours. A meso low formed within one storm with a strong hook echo signature and velocity signature noted over western Marion county, just west of Ocala and NW of the Ocala Regional Airport during the afternoon. The low level rotation weakened within a 15 minutes, but a tornado warning was issued as the strong was tracking eastward along a small scale warm front and continued to show very favorable radar signatures of rotation. The parent storm did some wind damage, but it eventually morph into a mesolow feature, with a trailing WSW squall line of storms that produced additional wind and hail damage just south of the rotating meso low over southern Marion county.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
903 AM EDT TUE SEP 24 2013

...FLOOD WATCH FOR MUCH OF NORTHEAST FLORIDA AND COASTAL SOUTHEAST
GEORGIA THROUGH THIS EVE...

.UPDATE...MSAS ANALYSIS WAS SHOWING A STATIONARY FRONT EXTENDING
FROM SOUTH OF THE I-10 CORRIDOR TO A BROAD AREA OF LOW PRESSURE
IN THE NE GULF. THIS LOW IS FORECAST TO TRACK TO THE EAST AND RIDE
ALONG THE FRONT TODAY AND THEN MOVE OFFSHORE TONIGHT. SHORT WAVE
ENERGY WILL COMBINE WITH ISENTROPIC LIFT AND TROPICAL MOISTURE
WHICH WILL LEAD TO NUMEROUS SHOWERS WITH A FEW EMBEDDED STORMS
POSSIBLE. TOTAL RAINFALL AMOUNTS OF 1 TO 3 INCHES IS VERY POSSIBLE
BY TONIGHT AND WITH THE GROUNDS ALREADY SATURATED IN MANY AREAS...
ANY ADDITIONAL HEAVY RAINFALL AMOUNTS COULD CAUSE LOCALIZED FLOODING.
A MAIN CONCERN IS THAT ALREADY NEARLY 3 INCHES OF RAIN HAS FALLEN
OVERNITE IN THE ST SIMONS ISLAND/BRUNSWICK AREA AND THIS AREA WILL
NEED TO BE CLOSELY MONITORED AS WELL FOR TODAY. HAVE EXPANDED THE
FLOOD WATCH TO INCLUDE COASTAL SE GA AS MORE BANDS OF HEAVY RAIN
COULD MOVE ACROSS THERE AGAIN INTO THIS EVE AS THE LOW TRACKS OFFSHORE.

&&

.AVIATION...BROAD LOW PRESSURE WILL TRACK ALONG A STATIONARY FRONT
ACROSS INTO NE FL BY LATE THIS AFTERNOON AND EVE. ISENTROPIC LIFT
AND TROPICAL MOISTURE WILL LEAD TO NUMEROUS SHOWERS AND POSSIBLY A
FEW EMBEDDED STORMS. PREVAILING MVFR CONDITIONS ARE EXPECTED TO
LINGER TODAY ACROSS ALL TERMINALS WITH OCNL IFR AND ISOLATED TS
POSSIBLE.

&&

.MARINE...A FRONT WILL REMAIN NEARLY STATIONARY ACROSS THE NE FL
WATERS THRU WED. LOW PRESSURE WILL TRACK ACROSS THE NE FL WATERS BY
THIS EVE AND MOVE WELL OFFSHORE TONIGHT. STRONG NE FLOW NORTH OF THE
FRONT WILL RESULT IN SCEC FOR THE GA WATERS INTO TONIGHT WITH WINDS
DECREASING SOME ON WED AS THE LOW MOVES WELL OFFSHORE. SOUTH OF THE
FRONT ACROSS THE NE FL WATERS WINDS EXPECTED TO REMAIN UNDER
HEADLINE CRITERIA WITH EAST WINDS 10 TO 15 KNOTS BECOMING SOUTHEAST
TONIGHT SHIFTING TO NORTHWEST LATER TONIGHT. WILL HAVE NUMEROUS
SHOWERS AND ISOLATED STORMS.

RIP CURRENTS: MODERATE RISK.

...FLOOD WATCH IN EFFECT FOR MUCH OF NORTHEAST FLORIDA AND
COASTAL SOUTHEAST GEORGIA THROUGH THIS EVENING...

...MODERATE RISK OF RIP CURRENTS AT AREA BEACHES...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST FLORIDA...
SOUTHEAST GEORGIA AND THE ADJACENT COASTAL WATERS.

.DAY ONE...TODAY AND TONIGHT...

A FRONTAL BOUNDARY POSITIONED ALONG THE INTERSTATE 10
CORRIDOR...IN COMBINATION WITH DEEP MOISTURE STREAMING
NORTHEASTWARD FROM THE GULF OF MEXICO...WILL CREATE PERIODS OF
HEAVY RAINFALL AND EMBEDDED THUNDERSTORMS ACROSS NORTHEAST AND NORTH
CENTRAL FLORIDA AS WELL AS COASTAL SOUTHEAST GEORGIA THROUGH
TONIGHT. WIDESPREAD RAINFALL AMOUNTS OF 1 TO 3 INCHES ARE EXPECTED
FOR THE WATCH AREA THROUGH TONIGHT...WITH LOCALLY HEAVIER TOTALS
POSSIBLE. THESE RAINFALL AMOUNTS MAY PRODUCE LOCALIZED FLOODING.
SCATTERED SHOWERS AND THUNDERSTORMS WILL GRADUALLY INCREASE IN
COVERAGE OVER INTERIOR PORTIONS OF SOUTHEAST GEORGIA THIS AFTERNOON
AND TONIGHT. THIS WILL BE IN ADDITION TO THE NEARLY 3 INCHES THAT
OCCURRED THERE.

A MODERATE RISK OF RIP CURRENTS IS EXPECTED AT AREA BEACHES DUE TO
A GROUNDSWELL AND ONSHORE FLOW.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY...

A DISTURBANCE ALOFT WILL ROTATE THROUGH THE EASTERN UNITED STATES
ON WEDNESDAY. ANOTHER PERIOD OF HEAVY RAINFALL ACCOMPANIED BY
STRONG THUNDERSTORMS WILL BE POSSIBLE REGION-WIDE ON WEDNESDAY AND
WEDNESDAY NIGHT. FLOOD WATCHES MAY BE EXTENDED IF WIDESPREAD
DOWNPOURS OCCUR. STRONGER THUNDERSTORMS WILL BE CAPABLE OF
PRODUCING GUSTY WINDS AND FREQUENT LIGHTNING STRIKES...IN ADDITION
TO LOCALIZED FLOODING. THE THREAT FOR HEAVY RAINFALL WILL DIMINISH
BY THURSDAY AS A DRIER AIR MASS GRADUALLY PUSHES SOUTHWARD INTO
OUR REGION.

HIGH PRESSURE WILL STRENGTHEN OVER NEW ENGLAND BY FRIDAY AND WILL
EXPAND SOUTHWARD DURING THE WEEKEND. THIS WILL CREATE AN EXTENDED
PERIOD OF STRONG NORTHEASTERLY WINDS OVER THE SOUTHEAST GEORGIA
AND NORTHEAST FLORIDA COASTAL WATERS...LIKELY BEGINNING ON
THURSDAY NIGHT OR FRIDAY MORNING. SMALL CRAFT ADVISORY CONDITIONS
ARE EXPECTED DURING MOST OF THE WEEKEND OVER THESE COASTAL WATERS.
BUILDING SEAS WILL CREATE AN ELEVATED RISK OF RIP CURRENTS AT AREA
BEACHES FROM FRIDAY THROUGH THE WEEKEND.

SPOTTER ACTIVATION IS NOT REQUESTED AT THIS TIME.
