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.

Area forecast discussion, Mar 9, 4:34 AM CST, 22 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
434 AM CST THU MAR 9 2006

.MESOSCALE UPDATE...
A SURFACE BOUNDARY REMAINS STALLED FROM NORTHEAST TEXAS INTO EXTREME
SOUTHEAST OKLAHOMA.  SMALL CONVECTIVE CELLS HAVE INCREASED SLOWLY
OVER NORTH-CENTRAL TEXAS AHEAD OF THE MAIN UPPER TROUGH WHICH IS
SWINGING ACROSS THE SOUTHERN PLAINS.  OVER THE LAST SEVERAL HOURS
THE ATMOSPHERE NEAR AND JUST SOUTH OF THE BOUNDARY HAS STABLIZED
SOME AS SURFACE DEW POINTS HAVE FALLEN SEVERAL DEGREES.  THIS
OFFSETS THE VERY FAVORABLE WIND FIELDS IN PLACE AHEAD OF THE
CONVECTIVE CELLS AND ULTIMATELY PLACES DOUBT ABOUT HOW STRONG
THESE STORMS CAN BECOME.  GIVEN THE SLOW INCREASE IN ACTIVITY
AND STRONG WIND FIELDS AS NOTED BY THE 500 TO 700 M2/S2 OF HELCITY
THE EVOLUTION OF THE SITUATION WILL HAVE TO BE MONITORED CLOSELY.

FURTHER NORTH THE LATEST IN LINE SEGMENTS TO MOVE TOWARD FORT SMITH
APPEARS TO BE NEAR SEVERE LEVELS.  WE HAVE JUST RECEIVED A REPORT OF
HAIL FROM ROLAND OK AND A SEVERE THUNDERSTORM WARNING IS BEING ISSUED
ON THE CELL FOR THE FORT SMITH AND VAN BUREN AREAS.
