Some people may have had thoughts about camping in Saskatchewan's beautiful Cypress Hills. Those people may very well be scrambling to change their plans.

A snowfall warning is in effect for the Shaunavon-Maple Creek-Val Marie-Cypress Hills region; specifically, for the higher elevations.

"We're sort of a bulletin board these days; we're getting darts thrown at us," says Environment Canada meteorologist Bill McMurtry about the weather pattern that has forced temperatures in five of the last six months below normal.

McMurtry says the high elevations in the Cypress Hills of southwestern Saskatchewan could get 10 to 20 centimetres, or 4 to 8 inches, of snow starting Friday night and into Saturday. The Waterton park area of southern Alberta could double that.

"There's quite an active low pressure system that's moving through Idaho and Montana right now," explains McMurtry, "and it's combining with some very cold air that's moving from Alberta and northern portions of Saskatchewan."

Frost warnings are also out for several regions in east-central Saskatchewan.

Early Friday morning, Regina and Saskatoon were among ten communities that set new record lows. McMurtry says it will remain unseasonably cold for the rest of the weekend.
