January 2010 ended up 4C warmer than normal in Winnipeg with a monthly mean temperature of -13.7C, compared to the 30 year average of -17.8C. The above normal temperatures were mainly due to a 2 week warm spell from the 10th to the 25th when temperatures were some 10-15C above normal. The mild spell included a record high of +4C on the 16th, the warmest reading of the month. There were only 2 days with temperatures of -30C or lower, occurring on the first two days of the month with a minimum of -34C on the 1st. Other than that, temperatures were quite tolerable for January.
Snowfall for the month was close to average with about 23 cm for the month. Much of it however fell during a storm system that affected southern Manitoba from the 22nd to the 25th with two waves of snow. The first wave brought 10-15 cm of heavy wet snow on the 22nd-23rd, which was followed by another 5-10 cm on the 24th-25th that was accompanied by strong winds and blizzard conditions. This led to severe travel disruptions throughout southern MB on the 25th with road and school closures due to the poor visibility. Other than that, precipitation was meager during January with little in the way of weather systems.
All in all.. a pleasant winter month with one major storm system.
