Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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.

NWS Tulsa, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 16, 3:12 PM CDT, 5 minutes earlier.

Area forecast discussion, Jun 16, 3:12 PM CDT, 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
312 PM CDT THU JUN 16 2011

.DISCUSSION...
CONVECTIVE COMPLEX CONTINUES TO MOVE ACROSS NORTHEAST OKLAHOMA
THIS AFTERNOON WITH AN OVERALL WEAKENING TREND NOTED OVER PAST
HOUR OR SO. THIS WILL HELP TO REINFORCE SFC BOUNDARY EXTENDING
FROM WEST CENTRAL KANSAS THROUGH EASTERN OKLAHOMA AND THE ARKANSAS
RIVER VALLEY. STORMS HAVE BEGUN TO DEVELOP OVER THE HIGH PLAINS
AGAIN THIS AFTERNOON AND SOME ADDITIONAL DEVELOPMENT MAY OCCUR
ALIGN ABOVE MENTIONED BOUNDARY THROUGH THE NIGHT. MID LEVEL TEMPS
WILL CONTINUE TO WARM AND BOUNDARY MAY DRIFT A LITTLE NORTH DURING
THE NIGHT. HOWEVER ITS PRESENCE DOES WARRANT AT LEAST SMALL
CHANCES OF ADDITIONAL STORMS THROUGH TONIGHT ACROSS NORTHERN
AREAS. PRE FIRST PERIOD WILL BE ADDED TO ZFP TO ACCOUNT FOR HIGH
POPS THROUGH THE LATE AFTERNOON...BUT MAJORITY OF CURRENT ACTIVITY
SHOULD BE OUT OF THE AREA BY 00Z.

SFC BOUNDARY WILL ULTIMATELY MOVE NORTH OF THE AREA FRIDAY...
THOUGH NOT BY MUCH AND THUS THERE REMAINS A NON-ZERO CHANCE OF
THUNDERSTORMS EACH OF THE NEXT FEW DAYS ACROSS NORTHEASTERN AREAS.
DOES APPEAR THAT A MORE EXTENSIVE CAP WILL SPREAD OVER THE REGION
AS UPPER RIDGE BUILDS SO THE CONFIDENCE LEVEL IS LOW IN ANY
ACTIVITY THIS FAR SOUTH...THUS WILL KEEP FORECAST DRY FRIDAY
THROUGH SUNDAY WITH HOTTER TEMPS DURING THAT TIME. SOME TRIPLE
DIGIT HIGHS POSSIBLE OVER WESTERN SECTIONS WITH HEAT ADVISORY
LEVELS MET LOCALLY.

STRONGER UPPER LEVEL LOW WILL MOVE ACROSS THE NORTHERN AND CENTRAL
PLAINS NEXT WEEK AND PUSH FRONT BACK TOWARD THE AREA BY TUESDAY.
THIS BOUNDARY WILL LIKELY BE PRESENT MUCH OF NEXT WEEK SOMEWHERE
IN THE VICINITY WITH INCREASING CHANCES OF SHOWERS AND
THUNDERSTORMS TUE/WED. INCREASED CLOUDS AND PRECIP WILL ALSO BRING
TEMPS BACK MORE TO NORMAL LEVELS FOR FOR JUNE...MAYBE EVEN BELOW
NORMAL FOR A CHANGE.

EVENING...WHICH RAISES THE RISK OF LOCALIZED FLASH FLOODING
ESPECIALLY FOR AREAS WHICH RECEIVED HEAVY RAINFALL THIS MORNING.

STRONG GUSTY WINDS ACROSS FAR NORTHWEST ARKANSAS WILL SUBSIDE
THIS AFTERNOON...WITH ANY ADDITIONAL STRONG WINDS BEING
THE RESULT OF THUNDERSTORMS.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...

MONDAY...THUNDERSTORM POTENTIAL...DANGEROUS HEAT POTENTIAL.

EXTENDED DISCUSSION...

WITH TEMPERATURES WARMING WELL ABOVE NORMAL.  THIS WILL
PRODUCE HIGH HEAT INDEX VALUES AND CAUTION SHOULD BE
EXERCISED IF OUTDOOR ACTIVITIES ARE EXPECTED. THE DANGEROUS
HEAT WILL CONTINUE INTO NEXT WEEK.  THUNDERSTORM
CHANCES WILL INCREASE FOR THE FIRST PART OF NEXT WEEK
AS THE NEXT FRONTAL BOUNDARY APPROACHES.
