The weather for January in Calgary has been so nice, usually in the +10° range, overnight lows rarely dipping much below zero. How things have changed, the forecast high for tomorrow is -25°, going down to -30° Tuesday night. And snow, tons of ugly, white snow. The streets have been perfectly dry lately, great for riding. Not any more, riding in this snow is going to be hell. The only bright spot is that the high for Thursday is forecast at -1°, so this cold snap might not last that long. Then again, they usually change the forecast day by day.
