Residents of Calgary and southwestern Alberta were greeted by a significant accumulation of snow on Saturday morning following 20 centimetres of snowfall in a 24 hour period.

According to CTV Meteorologist Steve Rothfels, the bulk of the snowfall has already landed in Calgary, Lower elevations within the city limits received approximately 15 cm of snow between Friday night and Saturday afternoon, while higher elevations are reporting roughly 25 cm. Rothfels predicts less than 5cm of snow will arrive in Calgary between Saturday afternoon and Sunday.

Snow and ice have made for slippery driving conditions around Calgary and in the mountain parks.
