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, 8.0 hours before the alert went out and 130 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.

What 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 Birmingham, AL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 1, 12:30 PM CDT, 2 hours 32 minutes earlier.
Area forecast discussion, Jul 1, 12:30 PM CDT, 2 hours 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BIRMINGHAM AL 1230 PM CDT SUN JUL 1 2012 .UPDATE...AVIATION DISCUSSION. && .DISCUSSION... THE OVERALL PATTERN HAS NOT CHANGED MUCH SINCE YESTERDAY. PRECIPITABLE WATER VALUES ARE UP SLIGHTLY AS CENTER OF RIDGE HAS PUSHED OFF TO THE EAST AND ALLOWED SOUTHERLY MID LEVEL FLOW TO SPREAD ACROSS ALABAMA. WITH THE AREA ON THE PERIPHERY OF THE UPPER HIGH...TEMPERATURES WILL BE SLIGHTLY COOLER TODAY. HOWEVER...SURFACE DEWPOINTS WILL ALSO BE HIGHER...SO HEAT INDICES WILL STILL BE NEAR 110 DEGREES OR HIGHER...AND THE EXCESSIVE HEAT WARNING CRITERIA WILL LIKELY BE MET IN SEVERAL AREAS. TOUGH CALL ON RAIN CHANCES TODAY. THE BETTER CHANCES SHOULD BE SOUTH OF I-20 WHERE PRECIPITABLE WATER VALUES ARE HIGHEST. ALSO...MODELS SHOW A LOW LEVEL CONVERGENCE ZONE SETTING BETWEEN BIRMINGHAM AND MONTGOMERY...WHICH COULD BE FOCUS FOR DEVELOPMENT. IF ACTIVITY CAN GET GOING...ANY STORM THAT DEVELOPS WILL HAVE THE POTENTIAL FOR DAMAGING WINDS...AND THE STORM PREDICTION CENTER HAS PLACED MOST OF THE AREA UNDER A SLIGHT RISK FOR SEVERE STORMS. THE HAZARDOUS WEATHER OUTLOOK WILL BE UPDATED TO INCLUDE ISOLATED DAMAGING WINDS. && .AVIATION... 18Z TAF DISCUSSION. HAZE AND ISOLD TSTMS WILL BE THE MAIN AVIATION HAZARDS THIS FORECAST PERIOD. A WEAK SFC TROF BETWEEN KEET AND KMGM WILL LIKELY BE THE FOCUS FOR ISOLD TSTMS FROM 20Z THRU 02Z. CONFIDENCE NOT ENOUGH FOR INCLUSION OF TSTMS AT ANY TAF SITE. HAZE WILL SETTLE OVER THE AREA AGAIN TONIGHT WITH MVFR VSBYS FROM 10Z THRU 14Z. 58/ROSE && .PREV DISCUSSION... /ISSUED 638 AM CDT SUN JUL 1 2012/ ANOTHER HOT DAY WITH TEMPERATURES AT OR ABOVE 100. HEAT INDICES APPROACHING 110 TO 112 IN A FEW AREAS AS DEWPOINTS HAVE CREPT UPWARDS OVER THE PAST 24 HRS. CURRENTLY...THE UPPER RIDGE IS CENTERED OVER GEORGIA WITH HOTTEST TEMPERATURES EXPECTED TO BE IN THE EASTERN COUNTIES THIS AFTERNOON. CURRENT PLAN IS TO LET THE HEAT WARNING CONTINUE DUE TO THE POCKETS OF HIGHER INDICES SPREAD OUT OVER THE CWA. ONE THING WHICH MIGHT IMPACT TEMPERATURES IS THE CLOUD COVER. IF IT REMAINS HIGH OVERCAST THEN THESE FORECAST TEMPERATURES COULD BE A COUPLE OF DEGREES TOO HIGH. SATELLITE AND SURFACE ANALYSIS SHOWING THE PLACEMENT OF A WEAK SURFACE TROUGH FROM THE CAROLINAS THROUGH GEORGIA AND INTO SOUTHERN ALABAMA. SOME ISOLATED CONVECTION COULD INITIATE OFF THIS BOUNDARY AS TEMPERATURES CLIMB INTO THE 100S...BUT ITS AROUND THE WESTERN PERIPHERY OF THE RIDGE WHERE THE BEST CHANCES OF ISOLATED OR EVEN SCATTERED CONVECTION POTENTIAL LIES. FORECAST SOUNDINGS REMAIN IMPRESSIVELY UNSTABLE SO IF ANY SIGNIFICANT UPDRAFTS CAN DEVELOP THEN SOME STRONG WIND GUSTS WOULD CERTAINLY BE POSSIBLE. THROUGH THE UPCOMING WEEK...THE RIDGE GRADUALLY WEAKENS AND ALLOWS FOR MORE CLIMATOLOGICAL RAIN CHANCES EACH AFTERNOON AND EARLY EVENING. TEMPERATURES BACK DOWN INTO THE MID 90S BY THE SECOND HALF OF THE WEEK. && .CLIMATE... SELECTED HEAT RELATED CLIMATE INFORMATION FOR THE NEXT FEW DAYS.
