CALGARY - Bundle up for the Grey Cup.

While a high of 9 C and mostly sunny skies are expected Sunday in Calgary, the sun will be setting and the temperature dropping to a low of -3 C when the Saskatchewan Roughriders and Montreal Alouettes meet at McMahon Stadium for the 4:30 p.m. MT kickoff.

Wind shouldn't be a major factor for kickers with a projected 10-kilometre breeze out of the west.

Both teams practised in extreme conditions this week. After two days of warm breezes, players and coaches dealt with snow on Friday. Things are expected to settle by Sunday.
