“Weather that is decidedly more like winter than summer,” says Environment Canada. (Even though it is technically still summer for another 10 days.)
12 Sep 2018 – Snow has begun to blanket parts of northern Alberta, including in Fort McMurray and Grande Prairie.
Environment Canada issued a special weather statement on Monday, saying a cool air mass will invade much of Alberta this week.
That statement was later upgraded to a snowfall warning for parts of northern Alberta, where between 10 and 15 centimetres of snow could fall.
