Frigid and Dry November Closes 18th Driest Fall
November actually began fairly mild... Our first accumulative snowfall of the season actually occurred on November 10, tying 14th latest first snowfall accumulation of fall since 1872. The latest was on November 21, 1963. 1981-2010 normal is October 18.
The dramatic turn to winter mid-month was by far the main story of November this year. The cold snap was unusually prolonged and lasted through to the end of the month. Lows dipped into the -20's on many occasions. The coldest low was -29.6°C on the 26th, the coldest temperature in November since 1996. Temperatures only topped out at -19.3°C on the 26th and 30th, the coldest highs in November since 1985.
In the end, November finished with an average of -8.8°C (4.2°C below normal), the 22nd coldest November on record since 1872. It was also the coldest since 1996 and the 9th coldest in the last century.
Looking at the future, luckily a warmup is in store for mid December. Models are in very high agreement that above normal temperatures will be dominant beginning next week, and this warmth may last more than just a few days. Questions still remain about how long the warmup will last however, as there has been talk of cooling down later in the month. Nonetheless, after the ridiculous cold of November, this warmup will be very welcomed.
November was also dry with just around 14 or 15 mm of precipitation recorded in Winnipeg. This came on the heels of a 3rd driest October. With only around 60 mm of precipitation this fall, it was the 18th driest fall since 1872.
