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.

Area forecast discussion, Jul 4, 3:21 PM CDT, 3 hours 1 minute before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOBILE AL 321 PM CDT FRI JUL 4 2008 .SHORT TERM TONIGHT AND SATURDAY...UNFORTUNATELY...EVENING BARBECUES MAY HAVE TO CONTEND WITH LINGERING THUNDERSTORM ACTIVITY CARRYING OVER FROM THE AFTERNOON. NOT LOOKING FOR A COMPLETE WASHOUT THOUGH...BUT LATE AFTERNOON/EVENING STORMS WILL BRING ABOUT DELAYS IN THE INDEPENDENCE DAY COOKING PLANS. SOME OF THE EVENING STORMS COULD BE STRONG AT TIMES AND CANNOT RULE OUT AN ISOLATED SEVERE STORM. HOWEVER...FORECASTERS ANTICIPATE COVERAGES OF THUNDERSTORMS TO DECREASE DURING THE COURSE OF THE EVENING DUE TO LOSS OF INSTABILITY. CLOUD DEBRIS FROM DECAYED THUNDERSTORM ACTIVITY IS ANTICIPATED TO BE HIGH ENOUGH AS TO NOT IMPACT FIRE WORKS VIEWING IN MOST AREAS LATER IN THE EVENING. THE GULF COAST REMAINS UNDER THE INFLUENCE OF A WEAK TROF OF LOW PRESSURE IN THE UPPER ATMOSPHERE...WHILE SURFACE HIGH PRESSURE PERSISTS FROM THE SOUTHWEST ATLANTIC INTO THE GULF. WITH DEEP LAYER MOISTURE (PRECIPITABLE WATERS 1.8 TO 2 INCHES) ALONG WITH DAYTIME INSTABILITY...ANOTHER ROUND OF SCATTERED THUNDERSTORMS SHOULD HAVE NO PROBLEM INITIATING ON WEAK MESOSCALE/SEA/BAY BREEZE BOUNDARIES ON SATURDAY. LITTLE CHANGE IN THE TEMPERATURE FORECAST WITH LOWS NEAR 70 INLAND TO MID 70S COAST AND DAYTIME HIGHS NEAR 90. /10 .LONG TERM SUNDAY THROUGH FRIDAY...SUBTROPICAL RIDGE WILL PERSIST FROM THE WESTERN ATLANTIC INTO THE NORTHERN GULF THROUGH THE MEDIUM RANGE. CHANCES FOR SHOWERS AND THUNDERSTORMS WILL BE NEAR CLIMATOLOGICAL NORMALS FOR THIS TIME OF YEAR...ROUGHLY 30 TO 50 PERCENT...PRIMARILY FROM THE LATE MORNING INTO THE EARLY EVENING AND NEAR THE COAST AND COASTAL WATERS LATE NIGHT AND EARLY MORNING. TEMPERATURES ALSO WITHIN A DEGREE OR TWO OF NORMAL. 10/11 && .AVIATION...EXPECT CONVECTIVE ACTIVITY TO BE NORTH OF THE TERMINALS WITH VFR CONDITIONS PREVAILING INTO THE EVENING.
