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
Jackson, MS (KJAN), launched 12:00Z, 7.6 hours before the alert went out and 60 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.

JAWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Jackson, MS wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 21, 1:52 PM CDT, 46 minutes earlier.
Area forecast discussion, Jun 21, 1:52 PM CDT, 46 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 152 PM CDT SAT JUN 21 2014 .SHORT TERM...A MORE ACTIVE DAY FOR STORMS IS IN PROGRESS DUE TO THE LESSENING INFLUENCE OF MID LEVEL HIGH PRESSURE. THIS ACTIVITY WHILE A LITTLE MORE ORGANIZED THAN FRIDAY IS STILL RATHER SCATTERED AND WILL POSE ONLY A SMALL SEVERE RISK. THE STORMS SHOULD LAST WELL INTO THE EVENING AND LIKELY DISSIPATE BY AROUND MIDNIGHT. AN ACTIVE CONVECTIVE DAY IS EXPECTED ON SUNDAY AS THE RIDGE WILL BE REPLACED BY A WEAK TROF IN THE MID LEVELS OF THE ATMOSPHERE. THIS SHOULD LEAD TO MORE WIDESPRED AND ORGANIZED STORMS FROM LATE MORNING INTO THE EVENING HOURS. DESPITE THE INCREASED ORGANIZATION...FLOW THROUGHOUT THE ATMOSPHERE WILL BE WEAK LIMITING THE STRENGTH OF THE STORMS. LOCALLY HEAVY RAIN WILL BE POSSIBLE DUE TO THE SLOW MOTION AND AROUND 2 INCH PRECIPITABLE WATER VALUES. POPS WILL RANGE FROM HIGH CHANCE TO LIKELY ON SUNDAY. EXPECT MONDAY TO BE LESS ACTIVE THAN SUNDAY BUT TO CONTINUE TO FEATURE SCATTERED AFTERNOON STORMS AS A BROAD MID LEVEL TROF REMAINS IN PLACE ACROSS THE REGION. /SW/ .LONG TERM...TUESDAY THROUGH SATURDAY...IT SHOULD BE A BIT MORE OF AN ACTIVE WEEK ACROSS THE REGION AS COMPARED TO THIS PAST WEEK. HIGH PRESSURE WILL NOT BE OCCUPYING OUR WEATHER BUT WE WILL INSTEAD BE LOCATED UNDER GENERAL TROUGHING WITH SOME DISTURBANCES MOVING ACROSS THE REGION. THIS WILL BRING GREATER COVERAGE OF CONVECTION THROUGH THE EARLY TO MIDDLE PORTIONS OF THE WORK WEEK. WITH PW VALUES AROUND 1.9-2 INCHES...HEAVY AND EFFICIENT RAINFALL WILL OCCUR. THERE WILL BE THE POTENTIAL FOR STRONG TO SEVERE STORMS ALMOST EVERY DAY AS COOL 500MB TEMPS WILL LEAD TO VERTICAL TOTALS AROUND 25-27C AND SBCAPES WILL BE SUFFICIENT AOA 3000 J/KG...ESPECIALLY IF WE CAN REACH INTO THE LOWER 90S. TEMPERATURES THROUGH THE PERIOD WILL GENERALLY BE IN THE LOWER 90S TO START OFF BUT CLOUDS...RAIN AND WET GROUNDS WILL LIKELY IMPACT HIGHS SLIGHTLY INTO THE MIDDLE/UPPER 80S FOR THE REST OF THE WEEK. OVERNIGHT LOWS WONT PROVIDE MUCH RELIEF WITH READINGS EXPECTED TO BE IN THE 70S AND PERHAPS SOME UPPER 60S. /28/ && .AVIATION...HRRR FORECAST VERIFYING WELL AT THE MOMENT WITH QUITE A BIT OF CONVECTION AROUND. MOST TAF SITES WILL BE IMPACTED WITH MAINLY VICINTY THUNDERSTORMS...BUT KJAN/KHKS/KHBG MAY ACTUALLY HAVE SOME THUNDERSTORMS WITH BRIEF IFR RESTRICTIONS TO VISIBILITY. THE CONVECTIVE POTENTIAL WILL LINGER ONCE AGAIN UNTIL AROUND 02Z WITH MVFR VISIBILITY RESTRICTIONS IN FOG DEVELOPING THEREAFTER...
