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 00:00Z, 0.9 hours before the alert went out and 85 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, Jun 19, 6:52 PM EDT, 2 hours 2 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 652 PM EDT FRI JUN 19 2015 .SYNOPSIS... THROUGH NEXT WEEK...ATLANTIC HIGH PRESSURE WILL PREVAIL WHILE A TROUGH OF LOW PRESSURE PERSISTS INLAND. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... THE HEAT ADVISORY EXPIRES AS SCHEDULED AT 7 PM. FOCUS FOR EARLY FRIDAY EVENING CONVECTION CONTINUED BETWEEN LAKE MOULTRIE AND THE SANTEE RIVER...NEAR THE MOUTH OF THE ALTAMAHA RIVER AND ACROSS INTERIOR SE GA JUST NORTH OF I-16. ADDITIONAL ISOLATED TO SCATTERED THUNDERSTORMS WILL CONTINUE TO DEVELOP AND DISSIPATE ALONG THE SEA BREEZE AND ALONG COMPLEX OUTFLOW BOUNDARIES FOR THE NEXT FEW HOURS. EVENTUALLY...DIURNAL STABILIZATION SHOULD TRANSLATE TO A GRADUAL DISSIPATION OF CONVECTION...WELL AFTER DARK...ALTHOUGH NON-ZERO POPS PERSIST THROUGH THE NIGHT. UNTIL AFTER SUNSET...A LOW PROBABILITY FOR BOUNDARY INTERACTIONS SUPPORTING BRIEF/PULSE STRONG TO SEVERE THUNDERSTORMS WITH FREQUENT LIGHTNING...STRONG WIND GUSTS AND VERY HEAVY RAIN WILL EXIST. OVERNIGHT...EXPECT ANOTHER VERY WARM AND HUMID NIGHT WITH LOWS ONLY IN THE MID 70S TO LOWER 80S. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/... ON SATURDAY...THE UPPER RIDGE OVER FLORIDA/SE GEORGIA AND SOUTHERN SOUTH CAROLINA WILL CONTINUE TO STEER THE SHORTWAVE TROUGH AND IT/S ASSOCIATED DEEP TROPICAL MOISTURE TO THE NW ACROSS THE TENNESSEE VALLEY REACHING THE MID ATLC COAST BY MID MORNING SUNDAY. A SLIGHTLY DRIER 1000-500 MB LAYER IS FORECAST TO MOVE INTO THE FORECAST AREA DURING THE DAY SATURDAY AND WE THINK THE DAY WILL REMAIN MAINLY CAPPED AND DRY. HOT TEMPS WILL PERSIST BUT IT LOOKS SURFACE DEW POINTS HAVE A CHANCE TO MIX OUT SLIGHTLY BETTER...ESPECIALLY INLAND AREAS. AFTERNOON HEAT INDICES WILL BE IN THE 102-105 DEGREE RANGE WITH THE SEA BREEZE CORRIDOR EXPECTED TO SEE THE HIGHEST APPARENT TEMPS BETWEEN 105 AND 108. WE THINK AFTERNOON CONVECTION WILL BE VERY SPOTTY AND WE MAINTAINED POPS BELOW 20 PERCENT. SATURDAY NIGHT...WE EXPANDED SOME LOW END CHANCES FOR SHOWERS AND TSTMS IN N-NW TIER OF ZONES AS THE BASE OF THE MID ATLC SHORT WAVE BRUSHES BY. LOWS WILL ONCE AGAIN BE IN THE MID 70S WITH UPPER 70S ALONG THE COAST. SUNDAY AND MONDAY...HOT AND MOSTLY DRY WEATHER WILL CONTINUE AS THE OVERALL WEATHER PATTERN CHANGES VERY LITTLE THROUGH THE PERIOD. SURFACE HIGH PRESSURE WILL PERSIST OVER THE ATLANTIC WHILE A TROUGH OF LOW PRESSURE SITS INLAND. ALOFT...THE RIDGE WILL STRENGTHEN LATE THIS WEEKEND INTO MONDAY ENSURING THE LONG DURATION SPELL OF HEAT GOES ON. ADDITIONAL HEAT ADVISORIES LIKELY BOTH DAYS AS HIGH TEMPS REACH THE MID/UPPER 90S. LARGE SCALE SUBSIDENCE WILL KEEP DIURNAL SHOWER/THUNDERSTORM COVERAGE ISOLATED AND MAINLY AS A RESULT OF THE SEA BREEZE AND/OR CONVERGENCE ALONG THE INLAND TROUGH. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... MID/UPPER LEVEL RIDGE WILL REMAIN ANCHORED OVER THE SOUTHEASTERN UNITED STATES THROUGH THE PERIOD...MAINTAINING TEMPERATURES WELL ABOVE NORMAL AND ONLY SLIGHT CHANCES POPS FOR AFTERNOON CONVECTION. AT THE SURFACE...ATLANTIC HIGH PRESSURE WILL PREVAIL WHILE A TROUGH OF LOW PRESSURE PERSISTS INLAND. MAIN CONCERN WILL BE THE CONTINUING HEAT. HIGH TEMPERATURES OF UPPER 90S TO NEAR 100 WILL COMBINE WITH MODERATE HUMIDITY TO PRODUCE HEAT INDICES UPWARDS OF 105 DEGREES EACH AFTERNOON. HEAT ADVISORIES WILL LIKELY BE NEEDED. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... THUNDERSTORMS COULD PERSIST NEAR KSAV TO START THE 00Z TAF PERIOD. OTHERWISE...VFR. THE PROBABILITY FOR THUNDERSTORMS NEAR THE TERMINALS WILL REMAIN TOO LOW SATURDAY AFTERNOON TO JUSTIFY ANY MENTION WITHIN 00Z TAFS. EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL PREVAIL. && .MARINE... ATLANTIC HIGH PRESSURE WILL REMAIN THE DOMINANT FEATURE OVER THE WATERS WHILE A TROUGH OF LOW PRESSURE PERSISTS INLAND. A FAIRLY ROBUST SSW SURGE IS EXPECTED TO DEVELOP OVER THE WATERS SATURDAY EVENING AS LOW PRES WELL TO THE NORTH ENHANCES THE PRES GRADIENT A BIT. WIND SPEEDS SHOULD INCREASE TO 15 TO 20 KT WITH SEAS BUILDING TO 4 FT OUTSIDE THE PILOT BUOYS DOWN TO GRAYS REEF. ADDITIONAL NOCTURNAL SURGES ARE LIKELY SUNDAY AND MONDAY EVENINGS WITH 15G20 KT AT TIMES. WINDS WILL BE LIGHTEST DURING THE POST-DAWN MORNING HOURS AS IS TYPICAL WITH THIS SYNOPTIC PATTERN.
