Decemeber 2010 was a fairly benign month with little in the way of major storm systems or extreme weather affecting Winnipeg. Most storms this month tracked to the west, south and east of the Red River valley, bringing heavier snow to southwest MB, North Dakota and NW Ontario. As a result, only meager snowfalls affected Winnipeg through the month, with only 16 cm for the month at my site.. welcome news after a snowy end to November. Temperatures for the month were a little above normal, with generally below normal temperatures in the first half of the month, and milder than normal conditions for the second half. Temperatures for the month at Winnipeg airport ranged from a low of -30.9C on the 13th to -2.4C on the 28th.
