It may have been a little warmer in the city as the record low was recorded at the airport... it was cold enough that my rear hub started to get a little skippy over the last km of a 7 km commute.
This was not as bad as spending a week commuting when the temperatures were consistently -35C to -42C during a nasty cold spell.
This is routine weather in Winnipeg and a little rarer for us, despite being a little farther north we do enjoy slightly better weather.
