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.

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 Charleston, SC wrote its last area forecast discussion before this severe thunderstorm warning went out at Feb 21, 11:18 AM EST, 7 minutes earlier.

Area forecast discussion, Feb 21, 11:18 AM EST, 7 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1118 AM EST FRI FEB 21 2014

.SYNOPSIS...
HIGH PRESSURE WILL RETREAT EASTWARD TONIGHT IN ADVANCE OF AN APPROACHING
COLD FRONT. THE COLD FRONT WILL SWEEP THROUGH THE AREA ON
FRIDAY...STALLING JUST OFFSHORE UNTIL STRONGER HIGH PRESSURE
BUILDS INTO THE AREA ON MONDAY. A LOW PRESSURE SYSTEM COULD
DEVELOP OFF THE SOUTHEAST COAST LATE TUESDAY INTO WEDNESDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
QUICK UPDATE TO REMOVE INLAND COUNTIES FROM THE WATCH. WITH THIS
LINE OF STORMS MOVING THROUGH QUICKLY...SE GA WILL BE OUT OF THE
THREAT BY 17Z AND SE SC BY 18Z. RADAR TRENDS HAVE BEEN SHOWING
WEAKENING...BUT DAMAGING WIND GUSTS ARE STILL POSSIBLE OVER THE
NEXT 2 HOURS.

&&

.SHORT TERM /SATURDAY THROUGH MONDAY/...
DRY HIGH PRESSURE WILL SETTLE OVER THE REGION ON SATURDAY. AMPLE
MOISTURE WITHIN A 105 KT JET OVER THE DEEP SOUTH WILL PRODUCE
EXTENSIVE CIRRUS WHICH WILL SLIGHTLY LIMIT INSOLATION. HOWEVER HIGH
TEMPS WILL STILL REACH 70F IN MANY SPOTS.

ON SUNDAY WE START TO SEE SOME CHANNELED VORTICITY ENERGY MOVE INTO
THE EASTERN UNITED STATES. MEANWHILE THE LOW-LEVEL RIDGE OVER THE
WESTERN ATLANTIC STARTS TO SHIFT EAST AS THE FLOW BACKS TO
SOUTHWESTERLY. AS LOW-LEVEL MOISTURE INCREASES...WEAK ISENTROPIC
ASCENT WILL DEVELOP ACROSS SOUTHEAST GA WITH SOME RAIN SHOWERS
POSSIBLE BY SUNDAY AFTERNOON. WE ADDED A SLIGHT CHANCE OF TSTMS
ACROSS FAR SOUTHERN AREAS BECAUSE A POCKET OF ELEVATED INSTABILITY
SHIFTS THROUGH DURING THIS TIME. LOW-LEVEL WARM ADVECTION WILL PUSH
HIGH TEMPS INTO THE LOWER TO MIDDLE 70S.

A BACKDOOR COLD FRONT WILL DROP INTO THE AREA SUNDAY NIGHT AND PUSH
OFFSHORE ON MONDAY. UPPER DYNAMICS ARE NOT VERY IMPRESSIVE
ACCOMPANYING THE FROPA SO WE ONLY HAVE 20-40 POPS SUNDAY NIGHT.

ON MONDAY...SLIGHTLY COOLER HIGH PRESSURE WILL BUILD IN FROM THE
NORTH WHILE THE BACKDOOR FRONT SITS JUST SOUTH OF THE AREA.
EXTENSIVE CLOUD COVER WILL ALSO PERSIST THOUGH THE BEST RAIN CHANCES
WILL BE FAR SOUTH CLOSER TO THE FRONT. WE SHOW HIGH TEMPS IN THE
MID/UPPER 60S.

&&

.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
THE LONG TERM PATTERN WILL MAINLY BE DOMINATED BY A LOBE OF THE
POLAR VORTEX MOVING INTO THE GREAT LAKES REGION LATE WEEK. MONDAY
NIGHT THROUGH WEDNESDAY THE UPPER PATTERN WILL BE TRENDING TOWARD A
BROAD TROUGH REGIME WITH A SERIES OF WEAK FRONTS AND LOW PRESSURE
WAVES AFFECTING THE FORECAST AREA. DUE TO LARGE UNCERTAINTIES IN
TIMING INDIVIDUAL FEATURES WE MAINTAINED A CONSERVATIVE FORECAST
WITH MAINLY SLIGHT CHANCES FOR SHOWERS AND HIGH TEMPS IN THE 60S.

A STRONG COLD FRONT WILL SWEEP THROUGH WEDNESDAY NIGHT... FOLLOWED
BY COOL CANADIAN HIGH PRESSURE THURSDAY AND FRIDAY. THIS WILL BRING
DRY CONDITIONS AND BELOW-NORMAL TEMPERATURES.

&&

.AVIATION /16Z FRIDAY THROUGH TUESDAY/...
PRIOR TO THE RAINS TODAY...GUSTY SW SURFACE WINDS AHEAD OF THE
SQUALL LINE ALONG WITH FAIRLY WIDESPREAD MVFR CIGS. THERE COULD BE
A BRIEF BOUT OF IFR CIGS BUT THE WINDOW LOOKS FAIRLY BRIEF. ADDED
THUNDER TO THE TAFS WITH THE LINE EXPECTED TO BE OVER KSAV AROUND
16Z AND KCHS AT 17Z. THERE IS NOT A LOT OF LIGHTNING WITH THIS
LINE...BUT THAT COULD CHANGE AS INSTABILITY INCREASES. SKIES WILL
BEGIN TO CLEAR OUT THIS EVENING WITH VFR CONDITIONS EXPECTED
TONIGHT IN THE WAKE OF A COLD FRONT.

EXTENDED AVIATION OUTLOOK...MVFR CEILINGS POSSIBLE AT KSAV SATURDAY
NIGHT AND AT BOTH TERMINALS SUNDAY NIGHT INTO MONDAY MORNING.
OTHERWISE VFR.

&&

.MARINE...
A SEVERE TSTM WATCH IS IN EFFECT FOR NEAR SHORE WATERS AND THE
CHARLESTON HARBOR.

OTHERWISE...NOT MUCH MIXING GOING ON OVER CHILLY SHELF WATERS AND IT
IS INTERESTING TO SEE WINDS GUSTS TO 20 KT AT TIMES AT CHARLESTON
AND SAVANNAH WHERE TEMPS HAVE WARMED TO THE UPPER 60S. TEMPS AT
GRAYS REEF NEAR 60 AND WINDS BELOW 10 KT ALL NIGHT WITH 2-3 FT
SEAS...QUITE THE STRONG MARINE INVERSION. SEAS WILL CONTINUE TO BUILD
OFFSHORE AND MAINTAINED A MARGINAL SCA FOR CHARLESTON COUNTY
WATERS MAINLY WELL EAST OF BULLS BAY. MOST NEAR SHORE WATERS TODAY
WILL SEE SW WINDS 15 KT OR SO AND SEAS 3-4 FT TOPS. THERE IS ALSO
A SCA FOR OUR OUTER GEORGIA WATERS WITH OCCASIONALLY GUSTY SW FLOW
AND SEAS 4-7 FT...HIGHEST NEAR THE WEST WALL OF THE GULF STREAM.

THE FRONT MOVES THROUGH THIS EVENING WITH WINDS SHIFTING W OR WNW
TONIGHT WITH COLD AIR ADVECTION MORE GRADUAL THAN SHARP...CONDITIONS
BELOW SCA CRITERIA.

MARINE WINDS/SEAS WILL BE RATHER LIGHT SATURDAY THROUGH SUNDAY
BEFORE A COLD FRONT DROPS INTO THE WATER SUNDAY NIGHT. WINDS WILL
INCREASE ALONG THE FRONT BUT THE STRONGER SURGE COMES MONDAY AS THE
FLOW BECOMES NE. CONDITIONS COULD FLIRT WITH ADVISORY LEVELS...
ESPECIALLY MONDAY NIGHT WHEN SEAS COME UP SOME.

THE NEXT SURGE COMES WEDNESDAY AND WEDNESDAY NIGHT BEHIND A STRONG
COLD FRONT. MODERATE CHANCES FOR SMALL CRAFT ADVISORIES WITH THE
MID-WEEK SYSTEM.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...NONE.
MARINE...SMALL CRAFT ADVISORY UNTIL 6 PM EST THIS EVENING FOR AMZ350-
