November 5th warmest, 2nd driest on record

After a rather chilly October, the weather pattern flipped in November to produce one of the mildest and driest Novembers on record in Winnipeg and southern Manitoba. Temperatures rose to above normal values on the 6th and stayed above normal every day through the end of the month. Winnipeg airport finished with a monthly mean temperature of +0.8C, the mildest November since 2001 (+0.9C) and the 5th mildest November since records began in 1872. Temperatures reached double digits on 10 days during the month, twice as many as October, and tying 1981 with the second most double digit days in November. In fact, the average daily high of +7.1C in November was just about the same as October (+7.3C) Combined with the warmest September on record, the 3 month fall period of Sep, Oct and Nov ended up tied with 1953 as the 4th mildest fall on record in Winnipeg with an average temperature of +7.3C. (Winnipeg's warmest fall was 1963 at 8.6C)

The big story however was the dryness of the month. Total precipitation at Winnipeg airport was only 1.5 mm .. tying 1901 and 1939 as the second driest November on record in Winnipeg (driest was 0.8 mm in 1976) All of the precipitation fell as melted snow with no rain during the month. The month was dominated by almost daily sunshine and mild temperature from the 4th to the 24th.. making it feel more like October than November. The extended fall weather and lack of snow allowed farmers to continue burning their fields well beyond the usual end date of Nov 15th.. requiring the province to extend the requirement for burning permits into December.

All in all.. a fabulous fall month.

  1. That snow to the north of the city appears to be just dancing in place. It intensifies and then fades back out but doesn't seem to be moving much.

  2. Did you remember back in 2002 we didn't have snow at the beginning of December until the middle of that month?

    In 1982, did you know that we had an above normal temps in early December?
