SHAWANO, Wis. -- A late-afternoon thunderstorm that drenched Shawano Speedway was ultimately too much to overcome, forcing the postponement of Wednesday night's World of Outlaws Late Model Series event.

The national tour's third annual visit to the half-mile oval 45 minutes Northwest of Green Bay has been rescheduled for Tues., Aug. 7. All tickets and pit bands purchased for Wednesday night's program will be good for admission on the race's new date.

While the skies cleared following the burst of rain and a large crowd filed into the speedway, all efforts to dry the clay surface for competition were unsuccessful. Shawano and WoO LMS officials jointly decided to postpone the event around 8:30 p.m. after it became apparent that the work would take an extended period of time to produce a surface suitable for safe racing.

'We certainly wish we could have run tonight's racing program as scheduled for all the fans and competitors who turned out,' said WoO LMS director Tim Christman. 'Unfortunately, Mother Nature just dealt us a tough hand tonight. Everyone made a great effort to get the track ready for racing ' we had packer trucks, IMCA Sport Mods and the track grader all attempt to bring the surface around, but racing tonight just wasn't in the cards.'

Thirty-eight cars were in Shawano's pit area for Wednesday night's program.

Shawano's rescheduled event will now close a stretch of WoO LMS racing in the Upper Midwest. The circuit will headline the 25th annual USA Nationals on Aug. 2-4 at Cedar Lake Speedway in New Richmond, Wis., and compete on Mon., Aug. 6, at Independence (Iowa) Motor Speedway.
