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

Springfield, MO (KSGF), launched 12:00Z, 11.5 hours before the alert went out and 102 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.

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 Tulsa, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 11, 3:30 PM CDT, 2 hours 58 minutes earlier.

Area forecast discussion, Jun 11, 3:30 PM CDT, 2 hours 58 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
330 PM CDT SAT JUN 11 2011

.DISCUSSION...

THE MAIN FORECAST CHALLENGE WILL BE CONVECTIVE CHANCES OVER THE
NEXT 24 HOURS.

A STALLED OUT FRONTAL BOUNDARY LIES FROM NEAR OR JUST SOUTH OF
THE I-40 CORRIDOR IN OKLAHOMA...ARCING BACK TO THE NORTHWEST INTO
THE CENTRAL HI PLAINS...AND TO THE NORTHEAST ACROSS AR INTO SE
MISSOURI.  SCATTERED SFC BASED THUNDERSTORMS HAVE DEVELOPED OVER
THE PAST HOUR ALONG AND SOUTH OF THE BOUNDARY...AND A FEW WIDELY
SCATTERED MAINLY ELEVATED SHOWERS AND THUNDERSTORMS EXIST NORTH
OF THE BOUNDARY. THE CAP IS WEAKER TODAY COMPARED TO
YESTERDAY...AND MID LEVEL WINDS ARE WEAKER AS WELL. THUS...EXPECT
SCATTERED MOSTLY DISORGANIZED PULSE TYPE CONVECTION THROUGH SUNSET
ACROSS MUCH OF THE REGION. A STRONG JET ALOFT WILL HELP VENTILATE
THE STORMS...SO A FEW SEVERE STORMS ARE POSSIBLE WITH DAMAGING
WINDS AND LARGE HAIL.

FOCUS THEN TURNS TO THE WEST FOR TONIGHT. STORMS ARE EXPECTED TO
FORM IN THE UPSLOPE FLOW REGIME ON THE HI PLAINS THIS AFTERNOON
AND EVENTUALLY GROW UPSCALE INTO AN MCS /STORM COMPLEX/ TONIGHT AND
MOVE GENERALLY EAST. THE TRACK OF THE SYSTEM IS STILL A BIT
UNCERTAIN...AND REALLY DEPENDS ON HOW FAR NORTH THE BOUNDARY
RETREATS. THE COMPLEX WILL LIKELY TRAVEL ALONG OR TO THE NORTH OF
THE FRONT TONIGHT...AND AFTER PERUSING ALL OF THE AVAILABLE MODEL
DATA THIS IS MOST LIKELY TO BE NEAR THE KS/OK BORDER. BY SUNDAY
MORNING...STORMS MAY DEVELOP TO THE SOUTHEAST INTO NW AR AS THEY
ROUND THE EDGE OF THE CAPPING EML. DAMAGING WINDS WILL BE THE
PRIMARY HAZARD.

UPPER HEIGHTS WILL RISE DURING THE DAY ON SUNDAY AND THE EML WILL
SPREAD NORTHEAST ACROSS THE FORECAST AREA AS THE FRONT RETREATS
BACK TO THE NORTH. THUS...PRECIP CHANCES WILL TAPER OFF FROM
SOUTHWEST TO NORTHEAST WITH TIME. BY MONDAY...MODELS SHOW
SOUTHWEST SFC WINDS AND HOT TEMPERATURES...WITH HIGHS IN THE UPPER
90S AND POSSIBLY NEAR 100 DEGREES TO THE WEST OF TULSA.

THE RIDGING ALOFT WILL BE FAIRLY SHORT-LIVED...AS MODELS FORECAST
A STRONG UPPER TROUGH OVER THE CENTRAL AND NORTHERN PLAINS BY
WEDNESDAY. THIS SYSTEM WILL PUSH A FRONT INTO OUR REGION LATE
TUESDAY INTO WEDNESDAY...AND AT LEAST SOME CHANCE FOR
THUNDERSTORMS CAN BE EXPECTED WITH IT.

THE GFS AND ECMWF CONTINUE TO DISAGREE WITH THE DETAILS IN THE
LATER PERIODS. THE GFS SHOWS MORE RIDGING ALOFT OVER THE FORECAST
AREA WITH THE RETREATING FRONT LIFTING NORTH INTO KS/MO BY FRIDAY.
THE ECMWF KEEPS THE FRONT FARTHER SOUTH AND IS MORE ZONAL WITH THE
PATTERN ALOFT. THE CANADIAN ENSEMBLES TEND TO FAVOR THE GFS
SOLUTION...HOWEVER GIVEN THE PERSISTENCE OF THE ECMWF...SLIGHT
CHANCE POPS ACROSS THE NORTH ARE WARRANTED FOR FRIDAY.

...DAMAGING WINDS POSSIBLE WITH STORMS THIS AFTERNOON AND EVENING...

THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

SEVERE THUNDERSTORM.
	RISK...SIGNIFICANT.
	AREA...EASTERN OKLAHOMA AND NORTHWEST ARKANSAS.
	ONSET...ONGOING.

        AREA AT GREATEST RISK...INTERSTATE 40 CORRIDOR.

DISCUSSION...
THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON ALONG A STATIONARY
FRONT ALIGNED ALONG INTERSTATE 40. ORGANIZED SEVERE WEATHER IS NOT
ANTICIPATED...BUT THE HOT AND DRY ATMOSPHERE WILL SUPPORT DAMAGING
WIND GUSTS...ESPECIALLY WITH STORMS THAT RAPIDLY COLLAPSE. SMALL
HAIL AND HEAVY RAIN WILL ALSO BE POSSIBLE. THUNDERSTORM ACTIVITY
AND THE SEVERE THREAT SHOULD DIMINISH WITH THE LOSS OF DAYTIME
HEATING.

LATE TONIGHT...A THUNDERSTORM COMPLEX THAT IS EXPECTED TO DEVELOP
THIS EVENING OVER THE HIGH PLAINS OF EASTERN COLORADO WILL
APPROACH PORTIONS OF NORTHEAST OKLAHOMA NEAR DAYBREAK. AREAS NEAR
THE KANSAS BORDER WILL BE MOST LIKELY TO BE AFFECTED BY THIS
COMPLEX...ALTHOUGH IT COULD REACH AREAS AS FAR SOUTH AS THE
HIGHWAY 412 CORRIDOR.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
ACTIVATION OF THE REGIONAL SPOTTER NETWORK WILL BE POSSIBLE.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
SUNDAY...THUNDERSTORM POTENTIAL.
MONDAY...HIGH WIND POTENTIAL.
TUESDAY AND WEDNESDAY...THUNDERSTORM POTENTIAL.
THURSDAY...NO HAZARDS.
FRIDAY...THUNDERSTORM POTENTIAL...DANGEROUS HEAT POTENTIAL.

EXTENDED DISCUSSION...
THUNDERSTORMS FROM THE AFOREMENTIONED COMPLEX MAY BE ONGOING
TOMORROW MORNING ACROSS PORTIONS OF NORTHEAST OKLAHOMA AND
NORTHWEST ARKANSAS. SMALL THUNDERSTORM CHANCES WILL BE BACK IN
THE FORECAST TUESDAY NIGHT AND INTO WEDNESDAY...AS A WEAK FRONT
MOVES INTO THE AREA. UPPER LEVEL RIDGING WILL AGAIN BUILD INTO THE
AREA LATE IN THE WEEK...WHICH WILL KEEP ABOVE NORMAL TEMPERATURES
AND HUMID CONDITIONS IN THE FORECAST.
