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

Birmingham, AL (KBMX), launched 12:00Z, 7.4 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.

.UPDATE...
FOR 18Z AVIATION.

.DISCUSSION...

A COMPLEX FORECAST FOR TODAY AND TONIGHT MAY FINALLY BE COMING
INTO BETTER FOCUS THIS MORNING WITH THE HELP OF SHORT RANGE
MODELS. THOUGH CONVECTION HAS FORMED NEAR THE GULF COAST THIS
MORNING...IT CONTINUES TO MOVE NORTHWARD INSTEAD OF STALLING...
WHICH MEANS IT IS LESS LIKELY TO BLOCK THE NORTHWARD MOVEMENT OF
THE WARM SECTOR. CURRENTLY A WARM FRONT IS LOCATED SOUTH OF THE
CWA ACROSS EXTREME SOUTH ALABAMA AND IS LIKELY TO HAVE TROUBLE
MOVING NORTHWARD...NOT BECAUSE OF COASTAL CONVECTION...BUT INSTEAD
A COOL WEDGE. EASTERLY FLOW ASSOCIATED WITH HIGH PRESSURE TO OUR
EAST IS EXPECTED TO PERSIST LONG ENOUGH TO LIMIT THE NORTHWARD
EXTENT OF THE SEVERE WEATHER POTENTIAL INTO THIS EVENING. THE LAST
FEW RUNS OF THE HRRR INDICATE THE WARM FRONT HAVING TROUBLE MOVING
NORTH OF A LINE FROM DEMOPOLIS TO EUFAULA THROUGH 00Z. MEANWHILE
THE HRRR ALSO SUGGESTS THE FOCUS FOR CONVECTIVE ORGANIZATION WILL
BE A BIT FARTHER WEST THAN PREVIOUSLY THOUGHT...NEAR THE FRONTAL
ZONE ACROSS EASTERN MISSISSIPPI...WHERE A QLCS MAY ORGANIZE THIS
AFTERNOON. IF THE AFOREMENTIONED SCENARIO OCCURS...THE BEST CHANCE
OF DAMAGING WINDS AND A TORNADO OR TWO WILL BE NEAR AND SOUTH THE
INTERSECTION OF THE QLCS AND THE WARM FRONT ACROSS THE SOUTHERN
THIRD OF THE FORECAST AREA STARTING AROUND 20Z IN THE SOUTHWEST.
THE FORWARD SPEED OF THE QLCS REMAINS IN QUESTION WITH MEAN-LAYER
FLOW NEARLY PARALLEL TO THE QLCS AND THE BEST UPPER-LEVEL FORCING
NOT EXPECTED TO DEVELOP UNTIL AFTER 03Z. THIS COULD LEAD TO FLASH
FLOODING TONIGHT IF THE QLCS SLOWS DOWN FOR AN EXTENDED PERIOD OF
TIME. THE QLCS WILL PROBABLY EXIT OUR SOUTHEAST COUNTIES BY 09Z
WEDNESDAY AS THE UPPER-LEVEL TROUGH BEINGS TO SHIFT EASTWARD.

THE FRONTAL PASSAGE WILL BRING AN END TO THE RAIN WEDNESDAY
MORNING AS COLDER AIR MOVES IN. DRY AND COOL CONDITIONS WILL
PERSIST INTO THURSDAY AND FRIDAY BEFORE ANOTHER SYSTEM DEVELOPS
FOR WITH FAIRLY HIGH RAIN CHANCES SATURDAY NIGHT INTO SUNDAY.

.AVIATION...
18Z TAF DISCUSSION.

IFR TO LIFR CONDITIONS WILL PERSIST THROUGH THE TAF PERIOD...WITH
LIMITED PERIODS OF MVFR. THE NEXT 12 TO 18 HOURS WILL BRING
WIDESPREAD SHOWERS AND THUNDERSTORMS ACROSS MOST TERMINAL
LOCATIONS. CEILING AND VISIBILITY CONDITIONS MAY IMPROVE SLIGHTLY
AS SHOWERS PASS OVER TERMINALS...BUT ONLY MARGINAL IMPROVEMENT CAN
BE EXPECTED. A COLD FRONT WILL MOVE THROUGH THE STATE
OVERNIGHT...EXITING ALABAMA WEDNESDAY MORNING. CONDITIONS WILL
IMPROVE AS DRY AIR SINKS INTO THE REGION ON WEDNESDAY.
