The radar

The Columbia radar (KCAE), 110 km from the middle of the area, began a volume at 22:44 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, 10.7 hours before the alert went out and 61 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.

Temperature in red, dew point in green, the mixed-layer parcel dashed.

Area forecast discussion, Jun 25, 4:23 PM EDT, 2 hours 21 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
423 PM EDT TUE JUN 25 2013

.SYNOPSIS...
BERMUDA HIGH PRESSURE WILL PREVAIL THIS WEEK...WHILE A WEAK TROUGH
OF LOW PRESSURE LINGERS INLAND. A COLD FRONT WILL APPROACH AND
POSSIBLY STALL NEAR THE AREA EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
INTO THIS EVENING...SCATTERED/NUMEROUS THUNDERSTORMS WILL CONTINUE TO
DEVELOP WHERE MESOSCALE BOUNDARY INTERACTIONS OCCUR ON THE PERIPHERY
OF A MID LEVEL SHORTWAVE TROUGH ADVANCING OFFSHORE. LOCALLY EXCESSIVE
RAINFALL AND BRIEF/PULSE SEVERE THUNDERSTORMS ARE POSSIBLE WHERE
BOUNDARY INTERACTIONS/CELL MERGERS OCCUR...ESPECIALLY ALONG/WEST
OF I-95.

THE FAVORED THUNDERSTORM REGIME ACROSS COASTAL SOUTH CAROLINA
SHOULD CONTINUE TO GRADUALLY SHIFT INLAND INTO AREAS ALONG/WEST
OF I-95 FOLLOWING THE SEA BREEZE AND OUTFLOW BOUNDARIES.
MEANWHILE...RADAR TRENDS SUGGEST THAT A BROAD PIVOT
POINT...ASSOCIATED WITH THE SHORTWAVE...EXISTS ACROSS CENTRAL
COUNTIES CLOSE TO I-95/THE KCLX RDA...AND MULTICELL CLUSTERS OF
THUNDERSTORMS SOUTH/WEST OF THIS AREA WILL TEND TO PUSH E/SE.
AS THE SHORTWAVE PUSHES FARTHER OFFSHORE...THE STEERING FLOW
AND/OR OUTFLOW BOUNDARIES WILL CONTINUE TO PUSH INLAND CONVECTION
BACK TOWARD THE GA COAST AND COULD ALSO PUSH THUNDERSTORMS BACK
TOWARD THE SC COAST THIS EVENING.

AS THE EVENING PROGRESSES...DIURNAL CONVECTION WILL EVENTUALLY
WANE/DISSIPATE. THEN...LOW LEVEL CONVERGENCE SHOULD SUPPORT
ISOLATED/SCATTERED CONVECTION ACROSS THE COASTAL WATERS AND
EVENTUALLY ACROSS COASTAL COUNTIES...ESPECIALLY LATE TONIGHT.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
ANOTHER TYPICAL SUMMER TIME WEATHER REGIME IS IN STORE FOR WEDNESDAY.
SURFACE HIGH PRESSURE WILL REMAIN CENTERED OVER THE ATLANTIC AND A
WEAK TROUGH WILL BE SITUATED INLAND. EXPECT COVERAGE OF SHOWERS AND
THUNDERSTORMS TO PEAK IN THE AFTERNOON AND GRADUALLY WANE AFTER
SUNSET. ON THURSDAY AND FRIDAY...AN UPPER LEVEL TROUGH AND
ASSOCIATED SURFACE LOW IS FORECAST TO SHIFT EAST TOWARDS THE REGION.
WITH DEEP MOISTURE IN PLACE AND BETTER DYNAMICS...CHANCES FOR
SHOWERS AND THUNDERSTORMS WILL REMAIN NON-ZERO THROUGH MUCH OF THE
REMAINING PERIOD. CANNOT RULE OUT A FEW SEVERE STORMS GIVEN THE
UPPER LEVEL SUPPORT AND MORE IMPRESSIVE INSTABILITY...SBCAPE
VALUES BETWEEN 2000-2500 J/KG.

TEMPERATURES ARE FORECAST TO BE AROUND NORMAL. THURSDAY LOOKS TO
BE A BIT WARMER WITH HIGHS IN THE LOW TO MIDDLE 90S AS MODEL
SOUNDINGS INDICATE MORE OF A WESTERLY/DOWNSLOPE COMPONENT. LOW
TEMPERATURES WILL BE IN THE LOWER TO MIDDLE 70S...CLOSE TO NORMAL
FOR THIS TIME OF YEAR.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
IT LOOKS LIKE A RELATIVELY ACTIVE EXTENDED PATTERN IS SETTING UP.
ALL OF THE GLOBAL MODELS DEPICT AN UNSEASONABLY STRONG LONGWAVE
UPPER TROUGH TAKING HOLD OF THE EASTERN UNITED STATES. A VERY MOIST
AIRMASS WILL BE IN PLACE WHILE A SERIES OF DISTURBANCES MOVE THROUGH
FROM SW TO NE. WE ARE SHOWING MOSTLY CLOUDY SKIES MUCH OF THE PERIOD
WITH 40 POPS DURING THE DAY AND 20-30 AT NIGHT.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
THUNDERSTORMS WILL DEVELOP INTO THE KSAV FROM INLAND THIS AFTERNOON...
AND ADDITIONAL INLAND THUNDERSTORMS COULD PUSH INTO THIS TERMINALS
INTO THE EVENING. ON THE OTHER HAND...THUNDERSTORMS WILL INITIALLY
PUSH INLAND AND AWAY FROM KCHS THIS AFTERNOON...BUT INLAND
THUNDERSTORMS COULD PUSH BACK INTO THIS AREA THIS EVENING.

OUTSIDE ANY FLIGHT RESTRICTIONS THAT OCCUR IN SHOWERS/THUNDERSTORMS...VFR
CONDITIONS SHOULD PREVAIL. LOW CHANCE FOR BRIEF FLIGHT RESTRICTIONS
DUE TO LOW LEVEL MOISTURE...ESPECIALLY LOWERING CEILINGS... LATE
TONIGHT INTO WEDNESDAY MORNING.

EXPECT AMENDMENTS THROUGH THE AFTERNOON TO FINE TUNE NEAR TERM
CONVECTIVE IMPACTS/TRENDS.

EXTENDED AVIATION...SCATTERED SHOWERS AND TSTMS EXPECTED EACH
AFTERNOON/EVENING WITH BRIEF REDUCTIONS IN VSBY/CIG POSSIBLE.

&&

.MARINE...
THE SEA BREEZE CIRCULATION WILL GIVE WAY TO SYNOPTIC S/SW WINDS UP
TO 15 KT THIS EVENING. ANY SHOWERS/THUNDERSTORMS THAT DEVELOP OVER THE
WATERS LATER TONIGHT COULD PRODUCE BRIEF WATERSPOUTS AND COULD
ALTER LOCAL WINDS. SEAS WILL AVERAGE 2 TO 3 FT NEARSHORE AND 3 TO
4 FT BEYOND 20 NM THROUGH TONIGHT.

FAIRLY QUIET MARINE CONDITIONS EXPECTED ON WEDNESDAY AS HIGH
PRESSURE REMAINS CENTERED EAST OF THE WATERS. SURFACE LOW PRESSURE
WILL APPROACH FROM THE WEST THURSDAY INTO FRIDAY...RESULTING IN A
TIGHTENED PRESSURE GRADIENT. SCA WILL BE POSSIBLE LATE THIS WEEK
INTO THE WEEKEND MAINLY IN THE NEARSHORE SC WATERS AS WINDS APPROACH
ADVISORY CRITERIA. GENERALLY EXPECT SEAS 2 TO 3 FEET ON
WEDNESDAY...BUILDING TO 4 TO 6 FEET BY THE WEEKEND...HIGHEST IN THE
OUTER WATERS.
