Verified. The Iowa Environmental Mesonet's Cow matched 3 storm reports to this severe thunderstorm warning; the first came 6 minutes after it went out.

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 12:00Z, 9.0 hours before the alert went out and 191 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, Jul 13, 3:18 PM CDT, 43 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
318 PM CDT THU JUL 13 2006

.DISCUSSION...
MAIN ISSUE WILL BE HEAT THROUGH MOST OF THE 7 DAY PERIOD...BUT
WILL NEED TO KEEP A CLOSE EYE ON MCS DEVELOPMENT TO OUR NORTH
LATER TONIGHT.

AT PRESENT AN MCV CONTINUES TO SLED ACROSS EASTERN OK AND HAS BEEN
GENERATING SHOWERS AND STORMS MAINLY ALONG ITS SOUTHERN PERIPHERY.
AS THIS FEATURE CONTINUES TO TRACK EAST IT MAY RESULT IN A FEW
STORMS OVER NW ARKANSAS EARLY THIS EVENING AND HAVE INCLUDED SOME
MINIMAL EVENING POPS THERE. ALSO...STRONG STORMS DEVELOPING ACROSS
EASTERN NEBRASKA WILL EVENTUALLY DEVELOP INTO A FORWARD PROPAGATING
MCS WHICH WILL MAKE A RUN AT PORTIONS OF NE OKLAHOMA AND NW
ARKANSAS LATE TONIGHT. WHILE THE MCS WILL WEAKEN AS IT MOVES TO
THE SOUTH...IT LOOKS ALMOST CERTAIN THAT AREAS ALONG KS BORDER
WILL SEE SOME RAINFALL AND HAVE GONE ABOVE MAV POPS FROM ABOUT
TULSA NORTH.

TEMPERATURES FOR FRIDAY WILL BE HIGHLY DEPENDANT ON EVENTUAL
PROGRESS OF MCS AND CLOUD COVER MAY INHIBIT AFTERNOON HIGHS SOME TO
THE NORTH OF I-40...OR NOT IF IT CLEARS EARLY ENOUGH. RECENT RAINS
WILL ALSO KEEP HIGH TEMPS DOWN SLIGHTLY THE NEXT DAY OR TWO IN AND
AROUND TULSA. HEAT INDICES OF 105+ CERTAIN TO THE SOUTH THE NEXT
FEW DAYS AND HAVE GONE AHEAD AND ISSUED AN EXCESSIVE HEAT WARNING
DUE TO THE EXPECTED DURATION. OVERNIGHT LOW CRITERIA WILL BE
MARGINAL. OPTED FOR A WATCH FOR NE OKLAHOMA DUE TO UNCERTAINTY
OF TEMPS FRIDAY...BUT BY THE WEEKEND THE UPPER RIDGE WILL BE
CENTERED OVERHEAD AND DAYTIME HEAT INDICES SHOULD MEET CRITERIA.

RIDGE AXIS SHIFTS FARTHER NORTH BY TUESDAY AND UPPER WINDS TAKE
IN A MORE EASTERLY COMPONENT. TEMPS SHOULD MODIFY SLIGHTLY AS A
RESULT AND TREND BELOW EXCESSIVE HEAT VALUES. THIS ALSO COULD OPEN
THE DOOR FOR ISOLATED AFTERNOON CONVECTION OVER THE TERRAIN AREAS
WITH COOLER MID LEVEL TEMPS...BUT WILL KEEP EXTENDED DRY FOR NOW.
