The plan was to cover a hill in a Cary park with about 10 inches of snow. The town sold 600 tickets at $10 each for Saturday and Sunday.
But town officials say it didn't seem fair to keep the money if everybody in the area gets snow for free.
If the snow does fall, Cary plans to refund the tickets and cancel the event. But if forecasters are wrong, the town will announce a new date for the event next week.
