Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
924 AM EDT TUE SEP 20 2011

.UPDATE...
A SOUTH TO SOUTHEAST STEERING FLOW HAS LIFTED OLD FRONTAL BOUNDARY
INTO AN EAST-WEST ORIENTATION ACROSS SOUTHEAST GEORGIA AND THIS IS
WHERE MOST OF THE RAINFALL IS EXPECTED TODAY WITH NUMEROUS SHOWERS
AND EMBEDDED TSTMS. FURTHER SOUTH IN THE WARM SECTOR ACROSS
NORTHEAST FLORIDA...DECENT DIURNAL HEATING INTO THE UPPER 80S TO
NEAR 90 SHOULD PROVIDE THE LIFT TO KICK OFF SCATTERED SHOWERS AND
THUNDERSTORMS DURING THE AFTERNOON AND EVENING HOURS. 12Z SOUNDINGS
STILL SHOWED PRECIPITABLE WATER AMOUNTS CLOSE TO 2 INCHES AND THIS
WILL CONTINUE THE THREAT OF LOCALLY HEAVY RAINFALL IN SOME SPOTS
AND IN ADDITION SOME LOCAL LOW LEVEL WIND BACKING TO THE E/SE DUE
TO SEA BREEZE ACTIVITY WILL ALLOW FOR WEAK ROTATION IN SOME OF THE
STORM ACTIVITY AND AN ISOLATED SEVERE TSTM WITH STRONG WINDS OR A
BRIEF TORNADO NOT TOTALLY OUT OF THE QUESTION.

&&

.AVIATION...
WITH OLD FRONTAL BOUNDARY NORTH OF MOST TAF SITES...EXPECT MAINLY VFR
CONDS WITH JUST TEMPO MVFR CIGS/VSBYS THIS AFTERNOON IN DEVELOPING
CUMULUS FIELD AND SCATTERED SHOWER AND TSTM ACTIVITY.

&&

.MARINE...
WINDS HAVE BASICALLY BECOME VARIABLE AT 10 KNOTS OR LESS ACROSS
THE WATERS WITH COMBINED SEAS OF 3-5 FT...MAINLY DUE TO SWELLS. NO
HEADLINES ARE EXPECTED AS MAIN THREAT TODAY WILL BE SCATTERED
SHOWER AND TSTM ACTIVITY WITH GUSTY WINDS AND LIGHTNING.

RIP CURRENTS: LINGERING EASTERLY SWELLS IN THE 2-4FT RANGE WILL
CONTINUE PROVIDE FOR A MODERATE RISK OF RIPS AT LOCAL BEACHES WITH
