Other than a few days of below normal weather during the third week of the month, January 2012 has been unseasonably mild over southern Manitoba, running some 7 degrees above normal to date (normal January monthly mean in Winnipeg is -17.8C) The month began with an exceptionally mild start averaging some 15C above normal over the first 10 days of the month, with temperatures soaring to record breaking values of +7C in Winnipeg on the 5th, and +12C over the western RRV. A mini cold snap between the 16th and 21st brought a spell of below normal temperatures in the minus 20s, but the cold snap was short lived as milder weather returned for the last 10 days of the month. As a result, Jan 2012 is on pace to finish with a mean monthly temperature around -10.8C, which would make it the third warmest January in Winnipeg since January records began in 1873. Only Jan 2006 (-7.4C) and Jan 1944 (-10.6C) have been milder in Winnipeg, with January 1942 currently the third warmest at -11.4C. In fact, if milder weather develops as predicted over the last couple of days of the month, January 2012 will challenge Jan 1944 as the second mildest January ever in Winnipeg. This comes off a mild December that was the 9th mildest on record finishing over 6C above normal. This January will also mark the 7th consecutive month of above normal temperatures in Winnipeg, going back to July 2011. And it looks like the above normal temperatures will continue into the beginning of February with well above normal temperatures likely to start the month. It's been quite the ride.. one wonders, how long will it continue?
