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 flash flood 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

Norman, OK (KOUN), launched 00:00Z, 9.1 hours before the alert went out and 254 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
NATIONAL WEATHER SERVICE TULSA OK
238 AM CDT SAT JUN 14 2008

.DISCUSSION...
WATCH #526 FOR MUCH OF EASTERN OKLAHOMA AND WATCH #527 FOR PARTS OF
WEST CENTRAL ARKANSAS ARE BOTH EFFECTIVE UNTIL 10Z. STRONG TO SEVERE
ELEVATED CONVECTION CONTINUES TO SLOWLY SHIFT SOUTH SOUTHEAST WITH
TIME AS AN 850 MB BOUNDARY CONTINUES PROVIDE THE FOCUS. MAY OPT TO
ADD PATCHY FOG TO NE OK AND NW AR ZONES AS SKIES CLEAR...BUT WILL
GAGE TRENDS JUST UP TO ZONE ISSUANCE. WILL TAILOR HIGHEST POPS
ACROSS SOUTHEAST OKLAHOMA THIS MORNING LARGELY BASED ON RADAR
TRENDS...THOUGH MODELS DISSIPATE CONVECTION BETWEEN 12 AND 18Z.
WILL PROCEED WITH CAUTION AND LEAVE POPS OUT FOR THIS AFTERNOON.
WEAKER CONVECTION MAY DEVELOP ACROSS SRN KANSAS LATE TONIGHT. SO
WILL GO AHEAD WITH LOW POPS ACROSS NE OK. BETTER CHANCES FOR AN
ORGANIZED MCS COME SUNDAY NIGHT AND MONDAY MORNING ACROSS FAR ERN
OK AND NW AR. OVERALL PATTERN HASNT CHANGED MUCH FOR THE
EXTENDED... AS NW UPPER FLOW...UPSLOPE SURFACE FLOW AND
UNACCOUNTED FOR SURFACE BOUNDARIES WILL ALL AID IN ADDITIONAL MCS
DEVELOPMENT FOR MUCH OF THE UPCOMING WEEK. BEST CHANCE FOR A DRY
DAY ACROSS ALL OF THE FA MAY BE WEDNESDAY...HOWEVER CONFIDENCE
REMAINS TOO LOW TO REMOVE POPS...SO WILL KEEP SLIGHT CHANCE
AREAWIDE. OTHERWISE...CHANCE POPS WILL BE THE RULE FOR THE
REMAINDER OF THE EXTENDED FORECAST. DIDNT STRAY TOO FAR FROM MOS
AS DEPICTING RAIN COOLED/DEBRIS CLOUDED AREAS REMAIN A CHALLENGE.
