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
Charleston AFB, SC (KCHS), launched 12:00Z, 7.5 hours before the alert went out and 140 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 8, 2:02 PM EDT, 1 hour 26 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE COLUMBIA SC 202 PM EDT MON JUL 8 2013 .SYNOPSIS... HIGH PRESSURE CENTERED OFF THE SOUTHEAST COAST WILL CIRCULATE A MOIST SOUTHERLY FLOW INTO THE FORECAST AREA THROUGH WEDNESDAY. A COLD FRONT WILL MOVE INTO THE REGION AND STALL LATE THURSDAY. && .NEAR TERM /THROUGH TONIGHT/... SURFACE ANALYSIS SHOWS A WEAK TROUGH OR AREA OF SURFACE CONVERGENCE FROM NORTHERN GA EAST-NORTHEAST ACROSS THE UPSTATE INTO EASTERN NC. 88D REGIONAL COMPOSITE ALREADY SHOWS SCATTERED SHRA/TSRA HAVE ALREADY DEVELOPED ALONG THE LINE. ADDITIONAL SHRA/TSRA ACTIVITY HAS ALSO DEVELOPED ACROSS THE CENTRAL MIDLANDS/CSRA. SPC MESOANALYSIS SHOWS THE CENTRAL MIDLANDS IN A VERY MOIST ATMOSPHERE WITH PW VALUES NEAR/AROUND 2.0 INCHES. THE AIRMASS HAS ALREADY BECOME UNSTABLE AND EXPECT THIS TO CONTINUE FOR THE REMAINDER OF THE AFTERNOON/EVENING. THE SINKING CONVERGENCE LINE...HIGH PW VALUES AND MODERATE INSTABILITY WILL HELP BE THE FOCUS OF ADDITIONAL SHRA/TSRA DEVELOPMENT. BELIEVE THE THREAT OF SEVERE WEATHER IS LOW. IF A STRONG STORM WOULD DEVELOP THE MAIN THREAT WOULD BE STRONG WINDS. HOWEVER...HAS IN RECENT DAYS THE MAIN THREAT WILL BE LOCALLY HEAVY RAIN. THIS IS BASED ON LOCAL HEAVY RAIN POTENTIAL WORKSHEET AND STORM MOTION AROUND 10 TO 12 MPH. CONVECTION EXPECTED TO DIMINISH DURING THE LATE EVENING AND OVERNIGHT PERIOD AS FORCING WEAKENS. HOWEVER...LOCAL MODEL SUGGESTS LINGERING SHOWERS ESPECIALLY ACROSS THE PIEDMONT/CSRA. OVERNIGHT TEMPERATURES HAVE BEEN IN THE LOWER TO MID 70S AND THIS WILL CONTINUE TONIGHT. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... HIGH PRESSURE CENTERED WELL OFF THE SOUTHEAST COAST WILL CONTINUE TO CIRCULATE MOIST AIR INTO THE FORECAST AREA. AIR MASS WILL LIKELY BE MODERATELY UNSTABLE EACH AFTERNOON AND EVENING. THE MODELS SHOW A WEAKNESS IN THE MID-LEVEL RIDGING AND SHORT WAVES MAY PROVIDE ENHANCED LIFT ACROSS THE AREA. FORECAST PRECIPITABLE WATER VALUES REMAIN ELEVATED AT 1.8 TO NEARLY 2 INCHES. GUIDANCE POPS SUGGEST SCATTERED THUNDERSTORMS MAINLY DIURNAL. USED THE GUIDANCE CONSENSUS FOR THE TEMPERATURE FORECAST. && .LONG TERM /THURSDAY THROUGH MONDAY/... THE GFS AND ECMWF CONTINUE TO SHOW A MOIST LOW-LEVEL ONSHORE FLOW DURING THE MEDIUM-RANGE PERIOD. DEEPENING UPPER TROUGHING IS FORECAST TO OCCUR ALONG THE EAST COAST WITH A CUT-OFF LOW DEVELOPING OVER THE SOUTHEAST STATES. COLD FRONT WILL MOVE INTO THE AREA LATE THURSDAY AND FRIDAY AND WILL PROVIDE FORECAST FOR CONVECTION. TROPICAL CONNECTION MAY ALSO ENHANCE PRECIPITATION. THIS PATTERN SHOULD RESULT IN SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS. TEMPERATURES SHOULD BE COOLER THAN CLIMATOLOGY. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... CONDITIONS CURRENTLY VFR ACROSS THE REGION. 88D REGIONAL COMPOSITE SHOWS WIDELY SCATTERED SHRA/TSRA DEVELOPING ACROSS THE CENTRAL MIDLANDS/CSRA AND ALSO ACROSS THE UPSTATE NC/SC BORDER. BASED ON RADAR TRENDS HAVE INCLUDED A TEMPO GROUP FROM 18Z THRU 20Z AT CAE/CUB FOR MVFR CONDITIONS. BEYOND THAT TIME PERIOD HAVE INCLUDED A VCSH FOR THE REMAINDER OF THE TAFS THROUGH 00Z. OVERNIGHT...MODELS NOT HANDLING THE POSSIBILITY OF LOW CLOUDS/FOG DEVELOPING OVERNIGHT. HAVE DECIDED TO MENTION A PERIOD OF MVFR FOG...BUT HAVE KEPT LOW CLOUDS SCATTERED WITH BROKEN MID CLOUDS. PLENTY OF LOW LEVEL MOISTURE OVERNIGHT...BUT RELATIVELY LIGHT WINDS. THIS WOULD TREND TOWARD A BETTER CHANCE OF FOG RATHER THAN STRATUS. EXTENDED AVIATION OUTLOOK...RESTRICTIONS POSSIBLE EACH DAY IN LATE NIGHT/EARLY MORNING FOG OR STRATUS AS WELL AS SCATTERED MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS. && .CAE WATCHES/WARNINGS/ADVISORIES...
