'Buffalo is prone to lake-effect winter storms that can dump several inches of snow on the area. That can be dealt with, but if there is a foot of lake-effect snow, that's bad news for the NHL. So would be temperatures of between 45 and 50, since the ice might not hold up. Also, if it's too cold, the ice will crack and chip. If it's a real sunny day the glare off the ice will create difficulty in seeing the puck.'
