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 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.

The nearest sounding before it

Tampa Bay, FL (KTBW), launched 00:00Z, 9.9 hours before the alert went out and 128 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.

EMBEDDED THUNDERSTORMS JUST AHEAD OF A COLD FRONT IS PUSHING INTO
THE AREA THIS MORNING. THIS LINE WILL CONTINUE TO PUSH THROUGH THE
AREA THROUGH THE MORNING AND EXIT THE AREA TO THE SOUTH THIS
AFTERNOON. WINDS ARE STILL STRONG AND BREEZY AHEAD OF THE FRONT
WITH GUSTS OF 20-30 MPH. HAVE RAISED A LAKE WIND ADVISORY FOR
TODAY BECAUSE OF THIS. THERE IS ALSO STILL THE POTENTIAL FOR
ISOLATED STRONG GUSTY TO POSSIBLY DAMAGING WINDS WITH AN EMBEDDED
STORM IN THE SQUALL LINE. HIGHS TODAY WILL LIKELY OCCUR THIS
MORNING AS TEMPERATURES ARE STILL IN THE LOWER TO MID 70S
CURRENTLY. TEMPERATURES ARE EXPECTED TO SLOWLY FALL THROUGH THE
DAY AND GENERALLY REMAIN IN THE UPPER 60S TO LOWER 70S. CLOUDS AND
CONVECTION SHOULD CLEAR OUT OF THE AREA TONIGHT AS HIGH PRESSURE
BUILDS ACROSS THE AREA FROM THE WEST. WINDS WILL QUICKLY DIMINISH
THIS EVENING AND AS COOLER AND DRIER AIR MOVES INTO THE
REGION...LOWS ARE EXPECTED TO FALL INTO THE UPPER 30S NORTH TO
THE LOWER 40S-AROUND 50 CENTRAL AND SOUTH. COOLER AND DRIER HIGH
PRESSURE WILL REMAIN ACROSS THE AREA THROUGH WEDNESDAY WITH HIGHS

SOUTHEAST U.S. COAST WEDNESDAY NIGHT AND TEMPS BEGIN TO INCREASE
AGAIN WITH FLOW BECOMING MORE SOUTHEASTERLY. THE ECMWF CONTINUES
TO BE QUITE A BIT SLOWER WITH THE NEXT SYSTEM MOVING INTO THE GULF
COAST STATES ON FRIDAY. THE GFS MOVES IT TO THE PANHANDLE BY
FRIDAY MORNING WHEREAS THE ECMWF STILL KEEPS IT BACK IN LOUISIANA
AT THE SAME TIME. BASED ON THE TRENDS FROM THE PAST FEW SYSTEMS
MOVING THROUGH THE AREA...WILL STICK CLOSER TO ECMWF
TIMING...MEANING HIGHEST POPS FOR OUR AREA DURING THE DAY ON
SATURDAY. HAVE GONE AHEAD AND INCREASED POPS TO 40 PERCENT FOR
THIS TIME PERIOD.

INTO SUNDAY.

&&

.AVIATION...LOW CEILINGS HAVE BEEN IN AND OUT OF THE TAF SITES
THIS MORNING AHEAD OF THE FRONT/CONVECTION. SHOULD SEE CLOUDS

QUICKLY...BUT BASED ON SATELLITE IMAGES...THE CLOUDS WILL LIKELY
LINGER THROUGH THE EARLY AFTERNOON HOURS (LATER OVER FMY/RSW).
WINDS WILL REMAIN GUSTY THROUGH SUNSET...SWITCHING TO THE
WEST/NORTHWEST AFTER THE FRONT MOVES THROUGH THIS MORNING.

&&

.MARINE...WINDS ARE GENERALLY 20-25 KNOTS WITH GUSTS UP TO 30
KNOTS ACROSS THE WATERS THIS MORNING. SEAS ARE UP TO 8 FEET
OFFSHORE. WILL KEEP THE SCA IN PLACE ACROSS THE WATERS THROUGH
