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.

Jackson, MS (KJAN), launched 12:00Z, 10.6 hours before the alert went out and 92 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 20, 3:49 PM CDT, 1 hour 45 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 349 PM CDT FRI JUL 20 2012 .SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT WENT CLOSE TO MAV NUMBERS FOR TEMPS THROUGH MONDAY WHILE BLENDING THE NAM MOS INTO HIGHS FOR SATURDAY. SHORTWAVE MOVING THROUGH ARKANSAS ON THE EASTERN SIDE OF THE RIDGE TO THE NORTHWEST WILL BE THE FOCUS TO MOVE A FRONTAL BOUNDARY INTO THE REGION SATURDAY AND INTO SUNDAY. TWEAKED MAV POPS SLIGHTLY FOR THE NEXT FEW DAYS WHILE TWEAKING POPS TONIGHT AND SATURDAY NIGHT UPWARD DUE TO THE CHANCES FOR NOCTURNAL CONVECTION. SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE AS THE FRONTAL BOUNDARY DRIFTS SOUTH. DRIER AIR...PWATS OF 1.5 TO 2.0 INCHES..WILL BEGIN TO FILTER IN THE NORTH TOMORROW EVENING INTO SUNDAY. CHANCES OF RAIN WILL INCREASE SUNDAY IN ADVANCE OF AN APPROACHING UPPER LOW THAT WILL DEVELOP OVER THE GULF COAST AND PROPAGATE TO THE NORTHWEST UNDER THE BASE OF THE RIDGE BUILDING TO THE EAST OVER THE CENTRAL GREAT PLAINS. FORECAST SOUNDINGS INDICATE TEMPS WILL DECREASE SLIGHTLY OVER THE NEXT FEW DAYS AS DRIER AIR AND COOLER TEMPS ALOFT WILL FILTER IN THE REGION. DID NOT MAKE ANY CHANCES PAST SUNDAY NIGHT SO PREVIOUS DISCUSSION FOLLOWS. /DC/ .LONG TERM...MONDAY INTO LATE WEEK... THE MID/UPPER HIGH WILL SHIFT POSITION AND BECOME MORE ORIENTED OVER OUR REGION. THIS WILL RESULT IN GENERALLY LESS PRECIP POTENTIAL EACH DAY AND TEMPS STEADILY WARMING DURING THE WEEK. GFS GUID TEMPS INDICATED THIS AND STEADILY WARMED INTO THE MID 90S FOR HIGHS. MOST OF THIS WAS ACCEPTED WITH JUST A COUPLE SMALL TWEAKS UPWARD AT SELECT SITES. THE LOW LEVEL FLOW WILL MAINLY HAVE A SW COMPONENT AND THIS SHOULD HELP READINGS FROM GETTING TOO HOT...MID 90S SEEMS TO FIT. AS FOR PRECIP POTENTIAL...THE GFS STILL IS THE MOST AGGRESSIVE AND INDICATES 30-40% CHANCES EACH AFTERNOON. THIS SEEMS A BIT OVER DONE AND POPS WERE LOWERED TO THE 20% RANGE (SLGHT CHC). ONE CONCERN FOR NEXT WEEK (ESP TUE-FRI) WILL BE THE HEAT INDEX. GOING FORECAST SHOWS A DECENT LIKELIHOOD OF VALUES NEAR 105 DEGREES DURING THIS TIME. ADVISORIES MAY BE NEEDED IF MID 90S OCCUR AND HUMIDITY HOLDS. /CME/ && .AVIATION... VFR CONDS MOSTLY PREVAIL MINUS BRIEF MVFR AT KHBG. TSRA HAS DVLPD BTW KHBG AND KMCB WITH TOPS AOA FL500.
