It happens but after the Blizzard of 77, the criteria for declaring a storm a *blizzard* were set up and conditions have to be almost life threateningly bad. Lots of snow and sustained winds of 35 mph or greater for several hours.
IF these are truly going to be blizzard or near blizzard conditions, they they are fools for not canceling the game. The fans MAY be able to dress for it, but the players will certainly suffer.
Pass out furry mittens and blankies for the players sitting on the bench.
