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 Jun 5, 1:30 PM EDT, 1 hour 51 minutes earlier.

Area forecast discussion, Jun 5, 1:30 PM EDT, 1 hour 51 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
130 PM EDT TUE JUN 5 2012

.SYNOPSIS...
A COLD FRONT WILL PUSH INTO THE AREA TODAY...THEN STALL AND WAVER
OVER OR NEAR THE REGION INTO THURSDAY NIGHT. HIGH PRESSURE WILL
BUILD OVER THE AREA INTO EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
LATEST SURFACE OBSERVATIONS SUGGEST A BACKDOOR FRONT IS BISECTING
THE FORECAST AREA BY MID MORNING. THE LARGE SWATH OF SHOWER
ACTIVITY BEHIND THE DESCENDING FRONT HAS GENERALLY REMAINED JUST
NORTH OF THE SANTEE RIVER DURING THE PAST FEW HOURS...WHILE MORE
CELLULAR CONVECTION HAS DEVELOPED SOUTH OF THE FRONT IN FAR
SOUTHEAST GEORGIA ZONES. MESOANALYSIS INDICATES THAT LOW TO
MODERATE INSTABILITY IS CURRENTLY CONFINED MAINLY SOUTH OF
INTERSTATE 16...WITH FORECAST MODEL SOLUTIONS KEEPING THE BEST
FORCING AND INSTABILITY ACROSS THIS SAME AREA THROUGH THE AFTERNOON
HOURS.

ABUNDANT SHORTWAVE ENERGY WILL CONTINUE TO STREAM INTO THE
SOUTHEAST STATES...TRAVERSING ALONG THE BASE OF A LONGWAVE TROUGH
ACROSS THE EASTERN UNITED STATES. ASSOCIATED DEEP MOISTURE AND
FORCING FOR ASCENT...AS WELL AS CONVERGENCE ALONG THE LINGERING
SURFACE FRONT...IS EXPECTED TO SUPPORT SCATTERED TO NUMEROUS
SHOWERS/THUNDERSTORMS FOR PORTIONS OF THE FORECAST AREA THIS
AFTERNOON. THE PRIMARY FORECAST CONCERN REMAINS THE POTENTIAL FOR
SEVERE WEATHER TODAY. STORM PREDICTION CENTER HAS MAINTAINED A
SLIGHT RISK FOR SEVERE THUNDERSTORMS OVER NEARLY THE ENTIRE
FORECAST AREA. HOWEVER THE TIMING...COVERAGE AND INTENSITY OF
CONVECTION COULD DIFFER QUITE A BIT DEPENDING UPON FRONTAL
LOCATION...MESOSCALE BOUNDARIES AND EFFECTS OF EARLIER CONVECTION.

CONSIDERING SOME STABILIZATION ACROSS FAR NORTHERN COUNTIES BEHIND
THE DESCENDING FRONT...INCLUDING THE CHARLESTON TRI-COUNTY
REGION...ORGANIZED SEVERE STORM DEVELOPMENT APPEARS LESS LIKELY AT
THIS TIME. AS THE COLD FRONT PUSHES SOUTH/SOUTHWEST THROUGH THE
LATE MORNING AND EARLY AFTERNOON HOURS...SEVERE WEATHER POTENTIAL
COULD BE MAXIMIZED ALONG/SOUTH OF INTERSTATE 16...WHERE A LONGER
PERIOD OF WARMING/DESTABILIZATION COULD OCCUR WELL AHEAD OF THE
SURFACE FRONT. THE SEVERE WEATHER THREAT WILL ARISE FROM A
COMBINATION OF ORGANIZED THUNDERSTORMS AND ASSOCIATED OUTFLOW
PUSHING INTO THE REGION FROM UPSTREAM CONVECTION...AS WELL AS
ADDITIONAL THUNDERSTORMS DEVELOPING ALONG BOUNDARIES OVER THE
AREA. DEEP LAYER SHEAR WILL SUPPORT MULTICELL THUNDERSTORMS WITH
OCCASIONAL SUPERCELL FEATURES. WILL CONTINUE TO ADDRESS THE SEVERE
POTENTIAL WITHIN THE HAZARDOUS WEATHER OUTLOOK AND MAINTAIN
LARGE HAIL AND DAMAGING WIND WORDING IN THE SPECIFIC FORECAST.

IT SHOULD BE NOTED THAT THERE ARE SEVERAL FACTORS THAT COULD LIMIT
THE SEVERE WEATHER POTENTIAL TODAY. EARLIER SHOWERS AND THUNDERSTORMS
ACROSS THE CHARLESTON TRI COUNTY REGION...AS WELL AS ONGOING WEAK
CONVECTION SOUTH OF INTERSTATE 16...COULD TEMPORARILY WORK OVER
THESE LOCATIONS. IF SHOWERS/THUNDERSTORMS BECOME MORE WIDESPREAD
THAN EXPECTED BEFORE THE PERIOD OF MAX HEATING...THAN SEVERE
WEATHER THREAT WOULD BE REDUCED. IN ADDITION...AREAS FALLING
BEHIND THE DESCENDING FRONT COULD SEE LESS HEATING AND
INSTABILITY...ESPECIALLY WHERE SKY COVER IS THICKEST.

DEPENDING ON PROGRESSION OF THE FRONT AND ANY BREAKS IN THE SKY
COVER...A DECENT TEMPERATURE GRADIENT COULD SET UP THIS AFTERNOON.
HIGHS COULD REMAIN IN THE 70S NORTH...WHILE LOCATIONS ALONG THE
ALTAMAHA RIVER COULD REACH 90 DEGREES BEFORE CONVECTION DROPS
TEMPERATURES QUICKLY THROUGH THE 70S THIS AFTERNOON.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
THE COLD FRONT WILL STALL OVER OR CLOSE TO SOUTHERN COUNTIES
TONIGHT...AND WITHIN AN ENVIRONMENT FEATURING DEEP LAYER FORCING
FOR ASCENT...INCLUDING UPPER LEVEL DIVERGENCE...SURFACE LOW
PRESSURE IS PROGGED TO DEVELOP WITHIN THE BAROCLINIC ZONE AND
TRACK EAST ALONG THIS BOUNDARY. THIS WILL HOLD MOISTURE AND THE
CHANCE FOR SHOWERS OVER THE REGION...WITH POPS GRADUATED FROM
CHANCE N/W TO LIKELY S. ALSO...AREAS OF STRATUS/FOG COULD
DEVELOP...BUT FORECAST CONFIDENCE REGARDING THE FOG IMPACT REMAINS
INSUFFICIENT TO JUSTIFY ANY MENTION WITHIN FORECASTS. WILL
CONTINUE TO ASSESS.

A STATIONARY FRONT WILL BE SITUATED ACROSS THE AREA EARLY WEDNESDAY
WITH AN AREA OF LOW PRESSURE DEVELOPING ALONG IT OFFSHORE. THE
COMBINATION OF THE FRONT...AREA OF LOW PRESSURE...UPPER TROUGH AND
SOME UPPER DIVERGENCE WILL YIELD A GOOD CHANCE FOR RAIN...ESPECIALLY
ACROSS SOUTHEAST GEORGIA. THE AREA OF LOW PRESSURE SHOULD MOVE
FARTHER OFFSHORE WEDNESDAY NIGHT AS THE UPPER TROUGH OVER THE EAST
COAST BEGINS TO SHIFT EASTWARD. THIS WILL ALLOW DRIER AIR AND HIGHER
PRESSURE TO MOVE IN AND THUS EXPECT LOWER RAIN CHANCES
THURSDAY...ALTHOUGH TEMPERATURES WILL BE BELOW NORMAL. HIGH PRESSURE
WILL BUILD IN EVEN MORE FRIDAY AND THIS SHOULD KEEP RAIN CHANCES
NON-EXISTENT EXCEPT FOR A FEW ISOLATED SHOWERS POSSIBLE ALONG THE
SEA BREEZE.

&&

.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
DEEP HIGH PRESSURE WILL MOVE IN THROUGH THE WEEKEND KEEPING RAIN
CHANCES VERY LOW. COULD SEE A SLIGHT INCREASE IN RAIN CHANCES EARLY
NEXT WEEK DEPENDING ON HOW QUICKLY THE UPPER RIDGE BREAKS
DOWN...WITH THE 00Z/05 ECMWF MORE AGGRESSIVE IN DOING SO COMPARED TO
THE 00Z/05 GFS. TEMPERATURES WILL BE NEAR NORMAL.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
VFR/MVFR CONDITIONS ARE SPORADIC AROUND THE CWA WITH THE STATIONARY
BOUNDARY. KCHS IS IN THE STABLE REGION AND INDICES SUPPORT MODERATE
SHOWER ACTIVITY THROUGH THE AFTERNOON AND EARLY EVENING. UPSTREAM
OBSERVATIONS ARE CARRYING CEILINGS AROUND 3KFT AND HIGHER. KSAV
HOWEVER IS IN THE UNSTABLE REGION AND THUNDERSTORMS ARE CURRENTLY
BUILDING FROM THE WEST AS A SERIES OF SHORTWAVES MOVE DOWN THE BASE
OF THE MID LEVEL TROUGH. THE HIGHER SURFACE TEMPS ARE KEEPING KSAV
IN VFR RIGHT NOW...BUT MVFR IS LIKELY WITH ANY THUNDERSTORMS THAT DO
FORM OVER THE TERMINAL. MODELS ARE SHOWING A SECOND ROUND OF SHOWERS
AND THUNDERSTORMS AFTER 00Z AND WITH THE ADDED LOW LEVEL MOISTURE...
WITH THE INCREASED LOW LEVEL MOISTURE AND COOLER TEMPS ON THE NORTH
SIDE OF THE FRONT...BOTH TERMINALS COULD SEE MVFR/IFR CONDITIONS IN
THE EARLY MORNING.

EXTENDED AVIATION OUTLOOK...LOW PROBABILITIES FOR SUB-VFR CONDITIONS
THROUGH EARLY THURSDAY...ESPECIALLY AT KSAV...AS A STALLED FRONT
LINGERS OVER/NEAR THE AREA.

&&

.MARINE...
A BACKDOOR COLD FRONT WILL STEADILY ADVANCE SOUTHWARD THROUGH THE
MARINE ZONES TODAY AND TONIGHT. WINDS WILL SHIFT TO THE
NORTH/NORTHEAST INITIALLY ACROSS SOUTH CAROLINA WATERS DURING THE
AFTERNOON HOURS. AS THE FRONT STALLS OVERNIGHT...WINDS COULD
BECOME LIGHT/VARIABLE OVER THE GEORGIA WATERS. SURFACE LOW
PRESSURE IS EXPECTED TO DEVELOP AND TRACK EAST ALONG THE
STATIONARY FRONT...AND THE TRACK/STRENGTH OF THIS LOW WILL
DETERMINE WIND DIRECTION/SPEED TONIGHT.

OVERALL...WINDS WILL REMAIN 15 KT OR LESS...WITH SEAS GENERALLY 3
FT OR LESS TODAY INTO TONIGHT. SEAS COULD BUILD TO 4 TO 5 FT
ACROSS OUTER GEORGIA WATERS LATE...BUT THAT WILL DEPEND ON THE
INFLUENCE OF THE SURFACE LOW.

WEDNESDAY THROUGH SUNDAY...A STATIONARY FRONT WILL REMAIN ACROSS THE
AREA THROUGH AT LEAST THURSDAY...BEFORE HIGH PRESSURE BUILDS IN FROM
THE NORTHWEST BY THE END OF THE WEEK. WIND SPEEDS AND DIRECTIONS
WILL BE A BIT DIFFICULT TO PIN DOWN...AS MUCH DEPENDS ON THE EXACT
LOCATION OF THE LINGERING FRONT. ALTHOUGH THERE WILL BE SOME
PERIODIC WIND/WAVE INCREASES THROUGH THE PERIOD...DO NOT ANTICIPATE
ANY ADVISORIES AT THIS TIME.

&&

.TIDES/COASTAL FLOODING...
PERIGEAN SPRING TIDES COULD PRODUCE MINOR SALT WATER FLOODING
DURING THE EVENING HIGH TIDE TONIGHT AND AGAIN WEDNESDAY NIGHT.
COASTAL FLOOD ADVISORIES COULD EVENTUALLY BE ISSUED.
