NCEI Storm Data entries that began inside the alert's area while it was in force. Before 2003 the local storm report archive is thin, so this is the record of what happened rather than what was phoned in.
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
Little Rock, AR (KLZK), launched 12:00Z, 6.5 hours before the alert went out and 209 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 22, 2:40 AM CDT, 10 hours 50 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 240 AM CDT MON JUL 22 2002 CONCERNS THIS FORECAST WILL BE WITH TSRA CHANCES THIS AFTERNOON... FOCUSING ON THE SW ZONES. FOR TODAY...BEST RAIN CHANCES LOOK TO BE ACROSS MY LA PARISHES AND SW MS...AS THIS AREA WAS BARELY TOUCHED BY SUNDAYS CONVECTION. REST OF THE FORECAST AREA WAS WORKED OVER BY STRONG CONVECTION...AND I FEEL THAT GUIDANCE IS A LITTLE ON THE AGGRESSIVE SIDE FOR POPS. WEST/SW AREAS CURRENTLY HAVE THE HIGHEST SFC MOISTURE AND THEY WILL RESIDE IN THE 850 THETA E AXIS TODAY. SFC HEATING WILL NOT BE A PROBLEM TODAY AND STORMS WILL FIRE WITHIN OUR MID/UPPER LEVEL TROUGH/SHEAR AXIS. THE AXIS OF THE TROUGH WILL BE MORE DISTINCT OVER THE W/SW AREAS WITH A BROAD AXIS ALONG AND SOUTH OF I-20. WILL GO LIKELY POPS SW ZONES AND SCT I-20 AND SOUTH. CONVECTION WILL DIMINISH AS THE SUN SETS AND WILL WORD ISOLATED POPS FOR TONIGHT. SFC TEMPS WILL RANGE BETWEEN 90-95 WITH SFC DEW PTS BETWEEN 70-75. THIS WILL RESULT IN HEAT INDICES BETWEEN 100-105. THIS IS A LITTLE LOWER THAN PREVIOUS DAYS AND WILL NOT MENTION IN ZONES. FOR TUE...SHEAR AXIS BECOMES MORE OF A CIRCULATION...WHICH WILL BE LOCATED TO THE EAST OF MS. THE AFFECT ON OUR WEATHER WILL BE LESS THUNDERSTORMS IN THE AFTERNOON...WITH THE TRADE OFF BEING HIGHER TEMPS. THE BEST RAIN CHANCES WILL BE OVER THE EAST...AS THEY WILL BE CLOSER TO THE CIRCULATION. INTO TUE NIGHT...GUIDANCE STILL INDICATING A WEAK FRONT MOVING INTO THE AREA. AVN IS STILL THE MOST AGGRESSIVE AS IT BRINGS THE FRONT TO MY SOUTHERN COUNTIES. I PREFER THE ETA...AS IT HAS THE FRONT ACROSS MY NORTHERN COUNTIES BY WED MORNING. THIS SFC BOUNDARY SHOULD REMAIN IN THIS GENERAL LOCATION THROUGH THE WEEK...PROVIDING SCT ACTIVITY. NO CHANGES TO THE EXTENDED. JAN 93/72/94/73/92 4222 MEI 93/71/94/73/91 3142 .JAN... AR...NONE. LA...NONE. MS...NONE. 36
