Sunday The warmest day of the outlook

The dry forecast supports outdoor plans, but shaded surfaces can still be slick early Friday where residual moisture froze overnight. The large day-to-night range at Kakabeka Falls also makes layered clothing more useful than a single heavy coat.
Wardrobe and travel
Wear a toque, gloves and a warm jacket for Friday morning, especially around Kakabeka Falls. A lighter mid-layer may be enough Saturday and Sunday afternoon in direct sun, but keep a wind-resistant outer layer for the evening. Drivers should watch for isolated frost on bridges and shaded rural roads during sub-zero mornings.
Weather trivia
Clear nights often cool faster than cloudy nights because the ground can lose more heat by infrared radiation. That helps explain why Kakabeka Falls can fall well below zero even as the following afternoon turns mild.
