Interesting looking at the last 5 Novembers.
2005 - AH (6.1c) AL (-5.5c) ADT (-0.4c)
2006 - AH (-0.9c) AL (-4.8c) ADT (-6.3c)
2007 - AH (4.7c) AL (-7.9c) ADT (-1.6c)
2008 - AH (7.1c) AL (-2.8c) ADT (2.2c)
2008 - AH (9.1c) AL (-4.3c) ADT (2.4c)
AH = Average high
AL = Average Low
ADT = Average Daily Temperature
Looking farther back when they started keeping records.
From years 1893 to 2005 Calgarys temperatures were: AH (2.8c) AL (-8.9c) ADT (-3.1c)
In that time there has been 14 years in the plus side for ADT.
8/14 came since 1980, 4 of those came in the 2000,s.
