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.

MESOSCALE FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OKLAHOMA
319 PM CDT SAT MAY 10 2003

AT 3PM THE DRY LINE EXTENDED FROM 15 MILES NORTH OF BARLTESVILLE TO
CHANDLER TO 25 MILES WEST OF ARDMORE.  A COLD FRONT WAS MOVING INTO
NORTHWEST OSAGE COUNTY AND WILL MERGE INTO THE DRY LINE AND CONTINUE
ON TO THE SOUTHEAST.  BY 10 PM THE THE FRONT AND DRY LINE MERGER
SHOULD BE COMPLETE ACROSS OUR AREA WITH THE FRONT AT THAT TIME
EXTENDING FROM NEAR EUREKA SPRINGS TO JUST WEST OF HUGO.

THE THREAT FOR SEVERE WEATHER WILL CONTINUE INTO THE EVENING HOURS A
HEAD OF THE MERGING FRONT AND DRY LINE.  THE LINEAR FORCING IS
EXPECTED TO INCREASE WITH THE ARRIVAL OF THE COLD FRONT AND WILL
CONTRIBUTE TO THE EVOLUTION OF A MORE LINEAR STORM EVENT WITH TIME.
HOWEVER THE MAGNITUDE OF THE SHEAR WILL SUPPORT OCCASSSIONAL
EMBEDDED SUPERCELL STRUCTURES.

STORM-RELATIVE HELICITY ANALYSIS SHOWS THE GREATEST VALUES OVER
PUSHMATAHA AND CHOCTAW COUNTIES.  CELLS THAT MOVE INTO THESE AREAS
WILL HAVE TO BE MONITORED FOR MORE LONG-LIVED SUPERCELL
CHARACTERISTICS.
