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, 2.6 hours before the alert went out and 122 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, Apr 8, 8:01 PM EDT, 2 hours 37 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
801 PM EDT THU APR 8 2010
.SYNOPSIS...
A COLD FRONT WILL APPROACH FROM THE WEST THIS EVENING AND PUSH THROUGH
THE AREA BY FRIDAY MORNING. COOL DRY HIGH PRESSURE WILL THEN BUILD
IN FOR THE WEEKEND AND REMAIN IN PLACE THROUGH THE MIDDLE OF NEXT
WEEK.
&&
.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
SHOWERS AND THUNDERSTORMS CONTINUE TO MOVE INTO THE WESTERN HALF
OF THE FORECAST AREA THIS EVENING AHEAD OF THE PRIMARY COLD FRONT
/NOW ACROSS CENTRAL GA AND PUSHING INTO THE EXTREME WESTERN
UPSTATE OF SC/. WITH THE LOSS OF DAYTIME HEATING...SURFACE
INSTABILITY FIELDS HAVE BEEN ON A DOWNWARD TREND. LATEST SPC
MESOANALYSIS INDICATES AS MUCH AS 500 J/KG OF SURFACE-BASED CAPE
ACROSS INTERIOR SOUTHEAST GA AND INLAND SC. HOWEVER THE SEABREEZE
HAS NOW MADE IT AS FAR INLAND AS ALLENDALE SC AND STATESBORO GA. A
MUCH MORE STABLE AIRMASS NOW EXISTS SOUTH AND EAST OF THIS
BOUNDARY WHICH IS STIFLING ANY CONVECTION THAT BRIEFLY PUSHES
ACROSS IT. THE THREAT FOR ANY SEVERE THUNDERSTORMS IS QUICKLY
DIMINISHING AS CAPES DECREASE AND THE SEABREEZE MOVES FARTHER
INLAND. THE SMALL REMAINING AREA OF OPPORTUNITY IS GENERALLY OUR
FAR INLAND GA COUNTIES WHERE A TORNADO WATCH CONTINUES UNTIL 11
PM.
ONLY MINOR TWEAKS PLANNED TO THE ONGOING FORECAST TO ALIGN WITH
LATEST RADAR TRENDS. CHANCES OF PRECIPITATION WILL QUICKLY
DIMINISH BY DAYBREAK FRIDAY AS THE COLD FRONT SHIFTS WELL OFF THE
ATLANTIC SEABOARD AND A STRONG H5 SHORTWAVE LIFTS NORTHEAST OF THE
REGION.
LAKE WINDS...A LAKE WIND ADVISORY FOR LAKE MOULTRIE IN BERKELEY
COUNTY WILL CONTINUE THIS EVENING AS GUSTY SOUTH SOUTHWEST WINDS ARE
EXPECTED AHEAD OF THE COLD FRONT. GUSTY CONDITIONS MAY EXPAND OVER
OPEN LAKE WATERS FOR A PERIOD THIS EVENING BEFORE SUBSIDING IN THE
FRONTAL TROUGH LATER TONIGHT.
&&
.SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY NIGHT/...
OTHER THAN SOME LINGERING CLOUDINESS AND PERHAPS A LEFTOVER SHOWER
EARLY FRIDAY MORNING ACROSS MAINLY THE TRI COUNTY AREA...SKIES WILL
BE OR QUICKLY BECOME MOSTLY CLEAR. COLD ADVECTION WILL BE OFFSET
SOMEWHAT BY GOOD DOWNSLOPE FLOW WHICH SHOULD ALLOW AFTERNOON HIGHS
TO CLIMB INTO THE LOWER TO MID 70S. WITH DEEP NORTHWESTERLY
FLOW...SEA BREEZE WILL BE PINNED AT THE COAST AND EVEN THE BEACHES
SHOULD REACH THE 70 DEGREE MARK. SURFACE HIGH PRESSURE WILL BUILD
TOWARD THE AREA FRIDAY NIGHT AND SATURDAY BEFORE SHIFTING SLOWLY
OFF THE COAST ON SUNDAY. LIGHT WINDS...CLEAR SKIES AND DEWPOINT
TEMPERATURES MAINLY IN THE UPPER 30S TO NEAR 40 WILL RESULT IN LOW
TEMPERATURES MAINLY IN THE LOWER TO MID 40S FRIDAY NIGHT. FOR
SATURDAY AND SUNDAY...PLENTY OF SUNSHINE WILL ALLOW AFTERNOON
TEMPERATURES TO CLIMB INTO LOWER TO MID 70S AWAY FROM THE COAST.
EXPECT THE SEABREEZE TO MAKE SOME PROGRESS INLAND ON SATURDAY AND
SUNDAY AFTERNOONS...WHICH WILL RESULT IN HIGH TEMPERATURES LIKELY
BEING KEPT IN THE MID TO UPPER 60S AT THE BEACHES.
&&
.LONG TERM /MONDAY THROUGH THURSDAY/...
ANOTHER EXTENDED PERIOD OF MAINLY CLEAR SKIES AND DRY WEATHER WILL
RESULT AS DEEP LAYERED RIDGING RETURNS TO THE AREA THROUGH AT LEAST
THE MIDDLE OF NEXT WEEK. A STRONGER AREA OF SURFACE HIGH PRESSURE
DEVELOPING OVER THE MID ATLANTIC STATES WILL RIDGE INTO THE
SOUTHEASTERN STATES THROUGH THE MIDDLE OF NEXT WEEK. NEAR NORMAL
TEMPERATURES ARE EXPECTED THROUGH THE MIDDLE OF NEXT WEEK WITH
BASICALLY NO CHANCE FOR RAIN.
&&
.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
GUSTY WINDS WILL CONTINUE AT BOTH TERMINALS THROUGH EARLY FRI
MORNING AHEAD OF AN APPROACHING COLD FRONT. ALTHOUGH SOME LIGHT
SHOWERS OUT AHEAD OF THE FRONT MAY FLIRT WITH THE TERMINALS
THROUGH 03Z...THE BRUNT OF THE FRONTAL PRECIPITATION IS EXPECTED
BETWEEN 03 AND 07Z. CONDITIONS ARE NOT FAVORABLE FOR CEILINGS TO
DROP LOWER THAN MVFR WITH THE FRONT...ALTHOUGH VSBY MAY DROP BELOW
3 SM BRIEFLY WITH HEAVIER SHOWERS. BY THE TIME THE ACTIVITY MAKES
IT TO THE TERMINALS WE SHOULD HAVE LOST ENOUGH OF THE AFTERNOON
HEATING TO PROMOTE CLOUD TO GROUND LIGHTNING. ALTHOUGH SOME
ISOLATED STORMS WILL STILL BE POSSIBLE...WE KEPT TSRA OUT OF THE
TAFS AT THIS JUNCTURE AND OPTED FOR A CB MENTION WITH SHRA.
LINGERING MVFR CEILINGS EXPECTED POST-FRONT BUT RAPIDLY DRYING
LOW-LEVELS BY DAYBREAK FRI WILL PROMOTE CLEARING. BREEZY
CONDITIONS AGAIN EXPECTED ON FRI AS THE GRADIENT REMAINS STRONG
BEHIND THE FRONT.
EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL CONTINUE FOR THE
REMAINDER OF THE PERIOD.
&&
.MARINE...
THE PRESSURE GRADIENT WILL CONTINUE TO TIGHTEN THIS EVENING AND
OVERNIGHT AS A COLD FRONT APPROACHES FROM THE WEST. WILL CONTINUE
SCA FOR THE CHS HARBOR AS WINDS INCREASE WITH THE ASSOCIATED
TIGHTENING OF THE PRESSURE GRADIENT. SCA CONDITIONS FOR THE CHS
HARBOR REMAIN FAVORABLE THROUGH EARLY MORNING FRIDAY WHILE 30-40 KT
LOW LVL WINDS SHIFT ALONG THE COAST.
HAVE MAINTAINED A SMALL CRAFT ADVISORY BEGINNING AT 5 PM THIS
EVENING FOR WATERS IN AMZ350 AND AMZ374. DESPITE COOLER
WATERS...A TIGHTENING PRESSURE GRADIENT ALONG WITH A SOUTHERLY
FETCH WILL ALLOW SEAS TO BUILD UP TO 4 TO 6 FEET EARLY
TONIGHT. THE HIGHEST SEAS WILL OCCUR OVER OUR NORTHERN WATERS.
WIND GUSTS WILL LIKELY REACH 25 KNOTS AS STRONG LOW LVL WINDS
SHIFT OVER THE WATERS AHEAD OF A COLD A FRONT.
A DECENT BUT BRIEF SURGE OF POST FRONTAL WINDS FRIDAY MORNING MAY
DELIVER SCA CONDITIONS TO THE GRAYS REEF AREA AND WE EXTENDED THE
SCA IN OUR 20-60 NM OUTER WATERS IN FRI MORNING TO ACCOUNT FOR THE
IMPROVED MIXING PROFILES.
WILL CONTINUE WITH SCA IN OUR 20-60 NM OUTER WATERS THROUGH FRI
MORNING AS GOOD MIXING IS EXPECTED TO OCCUR BEHIND THE DEPARTING
COLD FRONT. WINDS SHOULD SUBSIDE FRIDAY AFTERNOON ACROSS ALL WATERS
AS THE PRESSURE GRADIENT RELAXES AND WINDS ABOVE THE SURFACE WEAKEN.
MARINE CONDITIONS OVER THE WEEKEND INTO EARLY NEXT WEEK WILL BE
DOMINATED BY A LARGE HIGH PRESSURE AREA BUILDING OVER THE EAST COAST.
ONSHORE FLOW SHOULD BE A BIT STRONGER CLOSER TO GRAYS REEF SEAWARD
AND SEAS ALSO WILL BE A BIT ELEVATED CLOSER TO THE ALTAMAHA
RIVER. WE HAVE FORECAST CONDITIONS BELOW SCA CRITERIA IN OUR
SOUTHERN WATERS BUT NEED TO WATCH FOR LOCAL PINCHING AND SURGES.
