The Columbia radar (KCAE), 93 km from the middle of the area, began a volume at 22:56 UTC, the scan nearest the moment this went out.

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, 11.0 hours before the alert went out and 64 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 Columbia, SC wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 5, 5:54 PM EDT, 1 hour 3 minutes earlier.

Area forecast discussion, Aug 5, 5:54 PM EDT, 1 hour 3 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE COLUMBIA SC
554 PM EDT FRI AUG 5 2011

.SYNOPSIS...
A WEAK SURFACE BOUNDARY STRETCHING ACROSS THE AREA IS EXPECTED TO
LINGER THROUGH THE WEEKEND. THIS BOUNDARY COUPLED WITH AN UNSTABLE
AIRMASS AND AMPLE MOISTURE WILL KEEP THE CHANCE FOR MAINLY DIURNAL
THUNDERSTORMS THROUGH THE WEEKEND.

&&

.NEAR TERM /THROUGH SATURDAY/...
WITH STALLED FRONTAL BOUNDARY IN THE NORTHERN PART OF THE FORECAST
AREA...CONVECTIVE ACTIVITY DEVELOPED AND MOVED SOUTHWARD. SHOWERS
AND THUNDERSTORMS WITH VERY HEAVY RAIN AND LIGHTNING DETECTION
SYSTEM SHOWING A LOT OF LIGHTNING. SEVERAL SPS AND FLS STATEMENT '
BECAUSE OF THE HEAVY RAIN AND AN FFW FOR FIVE POINTS SECTIONS OF
COLUMBIA. OUTFLOW BOUNDARIES AND RAIN COOLED TEMPERATURES DOWN
INTO THE UPPER 70S AND LOWER 80S. AS A RESULT...CANCELLED THE
HEAT ADVISORY FOR THIS AFTERNOON AND EVENING. OTHERWISE...WEAK
DEEP LAYER SHEAR CONTINUES. SO EXPECT SLOW MOVING PULSE STORMS
WITH HEAVY RAIN. AIRMASS WILL BE MODERATELY UNSTABLE WITH
PRECIPITABLE WATER BETWEEN 2.0 AND 2.5 INCHES. POPULATED HOURLY
POP GRIDS FROM POPS FROM RADAR TOOL AND EXTRAPOLATED SOUTH AT 10
MPH THROUGH 01Z. THIS GAVE A FEW AREAS OF CATEGORICAL POPS ACROSS
THE REGION.

WITH THE WEAK FRONTAL BOUNDARY DRAPED ACROSS THE AREA SATURDAY...
THINK WE WILL HAVE PRETTY GOOD AERIAL COVERAGE OF CONVECTIVE
ACTIVITY AGAIN SATURDAY AFTERNOON. PLAN ON KEEPING THE GOING POPS
...30 PERCENT IN THE MORNING AND 50 PERCENT IN THE AFTERNOON. ALSO
...DECIDED THAT THE PREVIOUS APPARENT TEMPERATURES GIVING HEAT
INDEX VALUES IN THE 105-109 DEGREE RANGE FOR AN EXTENDED PERIOD OF
2-3 HOURS WOULD BE TOO HIGH, SO LOWERED BOTH TEMPS/DEWPOINTS 1-2
DEGREES FROM 18Z-22Z. THIS SHOULD KEEP THE HEAT INDEX VALUES
GENERALLY BELOW THE 105 DEGREE THRESHOLD. SO HELD OFF ON THE
ISSUANCE OF A HEAT ADVISORY FOR SATURDAY AFTERNOON.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/...
THE SURFACE FRONTAL BOUNDARY WILL LINGER ACROSS THE REGION AGAIN
ON SATURDAY...THEN TRY TO MOVE NORTHWARD AS A WARM FRONT ON
SUNDAY. WEAK SHORTWAVES WILL CONTINUE TO MOVE THROUGH THE UPPER
FLOW THROUGH THE WEEKEND. WITH THE INCREASE IN LOW LEVEL MOISTURE
AND ENHANCED CONVERGENCE ALONG THE SURFACE FRONT AND OUTFLOW
BOUNDARIES...STILL EXPECT A CONTINUED CHANCE OF THUNDERSTORMS
THROUGH THE PERIOD...ESPECIALLY DURING THE TIMES OF MAXIMUM
HEATING. MODEL SOUNDINGS STILL SHOWING HIGH PRECIPITABLE WATER
CONTENT THROUGH THE WEEKEND...SO SLOW STORM MOTIONS MAY LEAD TO
FLOODING IN POOR-DRAINAGE AREAS.

OVERNIGHT LOWS SHOULD BE IN THE MID/UPPER 70S...WITH DAYTIME
HIGHS IN THE MID TO UPPER 90S. ANOTHER HEAT ADVISORY WILL LIKELY
BE NEEDED SATURDAY.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
MEDIUM RANGE MODELS CONTINUE IN GENERAL AGREEMENT FOR THE LONG
TERM...CONTINUE TO RETROGRADE UPPER RIDGE WEST. BIGGEST DIFFERENCE
IS SHALLOW LONG WAVE TROUGH OVER EASTERN US IS EVEN FLATTER TODAY
THAN YESTERDAY WITH NEARLY ZONAL FLOW. FORECAST CHANGES WILL BE
MINIMAL. MAX TEMPS WILL BE IN THE MID TO UPPER 90S AND LOWS IN THE
MID 70S. ONLY SLIGHT CHANCE TO LOW CHANCE POPS FOR MAINLY
DIURNALLY FORCED SCATTERED CONVECTION.

&&

.AVIATION /22Z FRIDAY THROUGH WEDNESDAY/...
VFR CONDITIONS EXPECTED FOR MOST OF THE PERIOD...WITH MVFR
POSSIBLE IN AFTERNOON CONVECTION. WEAK FRONTAL BOUNDARY REMAINS
DRAPED ACROSS THE AREA. THAT FRONT...ALONG WITH CONVECTIVE OUTFLOW
BOUNDARIES...WILL CONTINUE TO BE A FOCUS FOR CONVECTION. EXPECT
SHOWER AND THUNDERSTORM DEVELOPMENT THIS AFTERNOON ACROSS NORTHERN
PORTIONS OF SC...THEN THE ACTIVITY WILL MOVE SOUTHWARD INTO THE
CENTRAL MIDLANDS AND CSRA LATER THIS AFTERNOON AND EVENING. WILL
PLACE CB IN ALL TAFS FOR A TIME DURING THE AFTERNOON...AND WILL
AMEND LATER ONCE CONVECTIVE TRENDS BECOME MORE INTO FOCUS. POTENTIAL
FOR HEAVY RAIN AND GUSTY WINDS FROM AFTERNOON AND EVENING
THUNDERSTORMS. FOG WILL BE POSSIBLE AFTER 06/06Z...HOWEVER
CONFIDENCE REMAINS LOW IN REGARD TO FOG AS MUCH WILL DEPEND ON
RAIN THIS AFTERNOON SO HAVE LEFT OUT OF TAFS ATTM.

EXTENDED AVIATION OUTLOOK...MVFR CONDITIONS POSSIBLE EACH DAY IN
EARLY MORNING FOG AND DURING AFTERNOON SHOWERS OR THUNDERSTORMS.
