WINSTON-SALEM, N.C. (AP) — NASCAR has adjusted the schedule for this weekend’s exhibition race at Bowman Gray Stadium in Winston-Salem in anticipation of more ice and snow blanketing the Winston-Salem area of North Carolina. The Clash was supposed to be a two-day event beginning Saturday with the main event held Sunday evening. To adjust, NASCAR has postponed all of Saturday’s on-track activity and will run the Clash as a one-day program Sunday. NASCAR believes even with cold temperatures, its Goodyear tires will produce enough grip on the quarter-mile Bowman Gray Stadium track to run Sunday at 6 p.m. If The Clash can’t run Sunday, NASCAR seems prepared to run the event on the next possible clear day; teams head to Daytona Beach, Florida, around Feb. 9 to begin preparations for the season-opening Daytona 500.
