COLD SNOWY SECOND HALF.. The dry and mild weather that dominated most of October continued in the first half of November with pleasant fall like conditions. Temperatures were above normal through the 16th, especially during the first 9 days of the month which saw temperatures in the double digits most days along with sunny skies. There was little in the way of weather systems through mid month, with only 1.8 mm of rain and a dusting of snow through the 17th. Things all changed by the 18th however as an Alberta clipper brought the season's first widespread snow over the Red River valley, including about 10-15 cm to Winnipeg on the 18-19th. That essentially marked the start of winter over southern Manitoba heralding the arrival of snowy weather and below normal temperatures for the latter half of the month. The initial snowfall on the 18th was followed three days later by a 12 cm snowfall, then another 23 cm on the 24-25th, ending with a 5 cm snowfall to close out the month on the 29-30th. By the end of the month, some 55.6 cm of snow had fallen on the city.. the heaviest November snowfall since 1996 (62.8 cm) and the 8th snowiest November on record in Winnipeg (since 1872) Normal snowfall for November is 21 cm. The above average snowfall resulted in the 4th consecutive month with above normal precipitation in Winnipeg, and the 5th wetter than normal month in the past 7. Temperature wise, the month finished with an average of -3.3C at YWG airport, about 2C above normal thanks to the mild first half. The early start to winter this year was in sharp contrast to last year which saw only 1.4 cm of snow all of November, and only 68 cm for the entire winter. The early snowpack on top of the saturated ground from the wettest April-October period on record has officials worried about prospects for severe flooding in the Red River valley next spring. All in all.. a fall-like first half followed by a winter-like second half.
