Snowfall of up to 20 centimetres is in the forecast for Calgary as Environment and Climate Change Canada issued a weather warning for several areas in Alberta.
Snowfall is expected to start Tuesday morning along the Rockies and spread eastward throughout the day.
Environment Canada has put a snowfall warning in effect for:
Airdrie - Cochrane - Olds - Sundre.
City of Calgary.
Crowsnest Pass - Pincher Creek - Waterton Lakes National Park.
High Level - Rainbow Lake - Fort Vermilion - Mackenzie Hwy.
Kananaskis - Canmore.
Okotoks - High River - Claresholm.
Between 10 and 20 centimetres of snow is expected in those areas by Wednesday evening, with the potential for more than 30 centimetres in mountain areas.
Kyle Fougere, meteorologist with Environment Canada, said there is still likely to be a little bit of melting because the ground is still warm, but that won't last for long as colder temperatures are in store over the next couple of days.
"We are expecting another system to move through in the weekend and that's going to drag in some substantially colder air from the north so that by the time we're looking at Monday morning, we could have temperatures of –19 degrees in the city of Calgary," he said.
Environment Canada cautioned that visibility may be suddenly reduced at times in heavy snow, and poor weather conditions may contribute to transportation delays.
The weather agency also warned to take frequent breaks and avoid strain when clearing snow.
