The Chinook winds have cleared away much of the snow in the Stampede City. But the Arctic front has returned and the forecast calls for a dusting of snow and a wind chill of minus 20 by the time the Optimist Clubs in Calgary and High River launch the 2nd Annual Sir John A's Great Canadian Kilt Skate. Once again, the skate will take place at Olympic Plaza between noon and 4 p.m.
