Saturday might have been the last unusually warm day for this time of year, as the snowing and blowing begins Sunday.
The high temperature Saturday, as recorded at CFB Trenton, was 15 Celsius.
That was close to the record high for a November 19.
But the 1985 high of 16.2C still stands.
Meanwhile, 10 to 20 cm of snow is expected, starting Sunday and continuing into Monday.
