The Columbia radar (KCAE), 122 km from the middle of the area, began a volume at 16:54 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, 4.9 hours before the alert went out and 132 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, Aug 11, 10:35 AM EDT, 2 hours 20 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
1035 AM EDT SAT AUG 11 2012

.SYNOPSIS...
AN APPROACHING COLD FRONT WILL BRING A GOOD CHANCE OF SHOWERS AND
THUNDERSTORMS THROUGH SUNDAY MORNING. THIS FRONT WILL STALL OVER THE
AREA AND DISSIPATE BY MONDAY. DRIER CONDITIONS ARE EXPECTED FOR THE
EARLY PART OF THE WEEK...BEFORE ANOTHER COLD FRONT BRINGS RENEWED
THUNDERSTORM CHANCES LATE TUESDAY AND WEDNESDAY. MORE SEASONABLE
WEATHER IS EXPECTED FOR THE END OF THE WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 10:30 AM SATURDAY...SIGNIFICANT AREA OF HEAVY RAIN AND
THUNDERSTORMS DEVELOPING ACROSS MID STATE SOUTH CAROLINA. WITH THIS
AREA EXPECTED TO PERSIST AND MOVE SLOWLY EAST...NORTHEAST...HAVE
INCREASED POPS TO CATEGORICAL AND ADDED HEAVY RAIN WORDING TO
WESTERN ZONES. THE 1200 UTC NAM HAS THIS AREA CAPTURED QUITE WELL.
TRIMMED BACK HIGH TEMPERATURES IN THESE AREAS AS WELL. NO OTHER
CHANGES. &&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
AS OF 300 AM SATURDAY...COLD FRONT WILL BE CROSSING THE CWA WHILE
DISSIPATING EARLY SUNDAY. ALTHOUGH SOME GUIDANCE HAS THE FRONT
CROSSING BEFORE THE START OF THE SHORT TERM...FAVOR THE SLOWER
SOLUTIONS WHICH SHOW FROPA BY EARLY SUNDAY AFTN DUE TO SOMEWHAT
BOUNDARY-PARALLEL MID LEVEL FLOW. FORECAST SOUNDINGS SUGGEST VERY
DRY AIR WORKING IN FROM WEST TO EAST BEHIND THE FRONT...SO ANY
PRECIP EARLY SUNDAY WILL FADE BY AFTN AND MUCH OF SUNDAY WILL BE
PRETTY NICE WITH INCREASING SUNSHINE. DRY WESTERLY FLOW PERSISTS
SUNDAY NIGHT AND MONDAY WITH PWATS FALLING TO BELOW ONE INCH. THIS
COMBINED WITH A CONVECTIVE LID NEAR 800MB WILL PREVENT ANY
CONVECTION MONDAY...AND WILL DROP INHERITED SCHC TO SILENT. TEMPS
SUNDAY WILL BE AT OR SLIGHTLY BELOW CLIMO WITH SOME WEAK COOL AIR
ADVECTION...BUT AMPLE AUGUST SUNSHINE WILL HELP RAISE TEMPS TO
AROUND 90 DURING THE AFTN...FALLING TO AROUND 70 SUNDAY NIGHT.
SIMILAR ON MONDAY...IF NOT A TOUCH WARMER...WITH LOWS ONCE AGAIN
AROUND 70.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
AS OF 300 AM SATURDAY...BROAD UPPER TROUGHING PERSISTS THROUGH
THURSDAY ACROSS THE SOUTHEAST BEFORE 500MB RIDGE BEGINS TO WORK BACK
INTO THE AREA FOR FRIDAY. UPPER TROUGH AND HENCE SLIGHTLY LOWER
1000-500MB THICKNESSES WOULD GENERALLY SUGGEST MODERATE DIURNAL
CONVECTIVE CHANCES DURING THE SUMMER...BUT OVERALL DO NOT ANTICIPATE
WIDESPREAD STORMS THROUGH MUCH OF THE PERIOD. THE EXCEPTION WILL BE
LATE TUESDAY AND WEDNESDAY AS A SHORTWAVE ROTATES DOWN THROUGH THE
BASE OF THE TROUGH AND DRIVES A COLD FRONT TOWARDS THE ILM CWA.
WINDS AHEAD OF THIS FEATURE FINALLY TURN SW ON TUESDAY...HELPING TO
FORCE THE MID LEVEL THETA-E RIDGE INTO THE MID-ATLANTIC...SERVING AS
THE FUEL FOR STORMS ALONG AND AHEAD OF THE COLD FRONT. TOO EARLY TO
GET VERY SPECIFIC IN THE DETAILS...BUT WILL CARRY CHC POP BEGINNING
LATE TUESDAY AND THROUGH WEDNESDAY FOR TSTMS. FRONT PUSHES OFFSHORE
LATE WEDNESDAY LEADING TO DRIER AND COOLER CONDITIONS
THURSDAY...BEFORE RIDGING DEVELOPS ALOFT FOR THE END OF THE WEEK.
TEMPS WILL BE RIGHT AROUND CLIMO MOST DAYS...POTENTIALLY WARMING TO
ABOVE CLIMO BY FRIDAY DUE TO INCREASING THICKNESSES AND RETURN OF SW
RETURN FLOW.

&&

.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
AS OF 12Z...EXPECT SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS
TO DEVELOP DURING THE PERIOD.  WHILE SHOWERS AND STORMS ARE POSSIBLE
THROUGHOUT THE FORECAST PERIOD...THEY ARE MOST PROBABLE DURING THE
12 HOURS FROM APPROXIMATELY 18Z THROUGH 06Z.  INTERMITTENT STORMS
WILL BE ACCOMPANIED BY MVFR OR SHORT DURATION IFR CONDITIONS.  S TO
SW WINDS OF 10 TO 15 KT THIS AM WILL DIMINISH TO 5 TO 10 KT THIS
AFTERNOON.

EXTENDED OUTLOOK...CHANCE OF MORNING MVFR VSBYS IN BR WITH A CHANCE
OF SHOWERS AND THUNDERSTORMS THROUGH SUNDAY. VFR MONDAY THROUGH
WED...OUTSIDE POSSIBLE SHOWERS AND STORMS TUESDAY NIGHT INTO WED.

&&

.MARINE...
NEAR TERM /THROUGH TONIGHT/...
AS OF 10:30 AM SATURDAY...WINDS AND SEAS ON THE WAY DOWN THIS MORNING
AS EXPECTED. ALL HEADLINES HAVE BEEN DISCONTINUED. COULD STILL SEE
SOME LOCALLY GENERATED HIGHER WINDS VIA CONVECTION BUT THESE WILL BE
ADDRESSED BY MARINE WEATHER STATEMENTS AND SPECIAL MARINE WARNINGS.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
AS OF 300 AM SATURDAY...COLD FRONT WILL BE SLOWLY MOVING ACROSS THE
AREA AT THE START OF THE PERIOD...WHILE AT THE SAME TIME WEAKENING.
SW WINDS OF 10-15 KTS THROUGH SUNDAY WILL GRADUALLY VEER TO THE WEST
AND EASE BY EARLY MONDAY AS FRONT WASHES OUT OVER THE WATERS. THESE
WINDS WILL CREATE 3-4 FT SEAS SUNDAY AS THEY WORK IN TANDEM WITH AN
INCREASING 2FT/9SEC SE SWELL. ALTHOUGH THE SE SWELL WILL PERSIST ON
MONDAY...WAVE HEIGHTS WILL GRADUALLY DECAY DUE TO THE DECREASING
WINDS...FALLING TO 2-3 FT THROUGH MONDAY NIGHT.

LONG TERM /MONDAY THROUGH TUESDAY/...
AS OF 300 AM SATURDAY...BERMUDA HIGH PRESSURE WILL CONTROL THE
SYNOPTIC FLOW TUESDAY...BEFORE A COLD FRONT WORKS THROUGH THE AREA
ON WEDNESDAY. THESE TWO FEATURES COMBINE TO CREATE INCREASING SW
WINDS BY TUESDAY NIGHT...RISING FROM AROUND 10 KTS EARLY
TUESDAY...TO AS MUCH AS 20 KTS BY EARLY WEDNESDAY...THANKS TO THE
TIGHTENING PRESSURE GRADIENT AHEAD OF THE COLD FRONT. THESE WINDS
FORCE RAPIDLY BUILDING WIND-WAVES...BECOMING 3-5 FT TUESDAY NIGHT
AND EARLY WEDNESDAY...AND A SCEC MAY BE NEEDED FOR A TIME. FRONT
WILL CROSS WEDNESDAY WHILE WEAKENING...AND WINDS WILL SLOWLY VEER TO
THE WEST BY LATE WEDNESDAY WHILE EASING TO AROUND 10 KTS. SEAS FALL
IN RESPONSE...BECOMING 2-3 FT BY THE END OF THE PERIOD.
