The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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.

The nearest sounding before it

Jacksonville, FL (KJAX), launched 12:00Z, 11.5 hours before the alert went out and 5 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jul 7, 2:09 PM EDT, 5 hours 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
209 PM EDT SAT JUL 7 2012

.SHORT TERM...
SATELLITE SHOWS A SEA BREEZE PUSHING INLAND ALONG THE BIG BEND TO
TAMPA AND ALSO ON THE EAST COAST SOUTH OF ST. AUGUSTINE. A FEW
SHOWERS ARE POPPING ALONG THE SEA BREEZE FRONT. CUMULUS IS MORE
SPARSE OVER SE GA. BLENDED TOTAL PRECIPITABLE WATER (PWAT) PRODUCT
INDICATES PWATS ARE AROUND 1.8 INCHES AND 2 INCHES ALONG THE EAST
COAST. STRONG RIDGE ALOFT TO OUR NORTH WILL HELP LIMIT CONVECTION
OVER SE GA THIS AFTN WHILE SCATTERED STORMS WILL DEVELOP OVER
INTERIOR NE FL DUE TO SEA BREEZE AND OUTFLOW BOUNDARY COLLISIONS.

ON SUNDAY THE MID LEVEL HIGH PRESSURE WILL BUILD OVER THE GEORGIA
AND THE CAROLINAS ACTING TO SUPPRESS CONVECTION AND HAVE LOWERED
POPS TO NEAR 10% FOR SE GA WITH 20-30% FOR INTERIOR NE FL. BEST
CHANCE WILL BE BETWEEN HWY 301 AND I-95 AFTER 5 PM. THEN ON MONDAY
THE HIGH WILL DRIFT INTO THE ATLANTIC IN RESPONSE TO AN
APPROACHING SHORTWAVE TROUGH. CONDITIONS WILL REMAIN SIMILAR WITH
SCATTERED AFTN/EVENING SHOWERS/STORMS LAUNCHED ALONG THE SEA
BREEZES IN NE FL AND ISOLATED ACTIVITY OAVER THE SUWANNEE RIVER
VALLEY INTO SE GA. TEMPERATURES WILL REMAIN IN THE MID 90S
PRODUCING HEAT INDICES OF 100 TO 105.

.LONG TERM /TUESDAY THROUGH SATURDAY/...
HIGH PRESSURE RIDGE SOUTH OF THE FORECAST AREA WILL SLOWLY WEAKEN
MID TO LATE WEEK AS A TROUGH AMPLIFIES OVER THE SOUTHEAST U.S. A
DEEP AND MOIST SOUTH TO SOUTHWESTERLY FLOW WILL SET UP WITH
PRECIPITABLE WATER INCREASING TO 2 INCHES OR MORE. THIS
CORRESPONDS TO INCREASING RAIN CHANCES LATE IN THE WEEK. POPS
WILL BE NEAR 30% TUE/WED AND INCREASE TO 50% OR HIGHER THU- SAT.
TEMPERATURES WILL BE NEAR CLIMO THROUGH THE WEEK.

&&

.AVIATION...
THE COMBINATION OF CONVERGENCE ASSOCIATED WITH THE SURFACE TROUGH
AND LIFT PROVIDED BY SEA BREEZE BOUNDARIES WILL LEAD TO ISOLATED
TO SCATTERED THUNDERSTORMS ACROSS SOUTHEAST GEORGIA AND NORTHEAST
FLORIDA THIS AFTERNOON AND EARLY EVENING.
