The winter storm warning issued for much of southern Alberta Saturday is now upgraded to a blizzard warning, according to Environment Canada.

Blizzard conditions will develop Sunday evening and into Monday as an intense storm moves through Alberta. Parts of northern Alberta have already seen heavy snow begin to fall, and that is expected to spread to southeastern Alberta by Monday afternoon.

While most areas are expecting 10 to 20 centimetres of snow, some could get walloped with as much as 30 centimetres by Tuesday morning.

"It will be the biggest snowstorm of the season," said CBC's weather specialist, Jodi Hughes. "What we're watching for is an Arctic cold front that's developing [and] going to track down across the province and it's bringing with it an incredible amount of snow."

Environment Canada says the storm system will bring cold Arctic air on Monday, and winds gusting above 60 kilometres per hour will produce blizzard conditions in areas east of the Foothills.

Ahead of the storm, some areas may also see freezing rain Sunday afternoon.

The areas currently under a blizzard warning are:

- Airdrie - Cochrane - Olds - Sundre

- Brooks - Strathmore - Vulcan

- City of Calgary

- Cypress Hills Provincial Park - Foremost

- Drumheller - Three Hills

- Hanna - Coronation - Oyen

- Lethbridge - Taber - Milk River

- Medicine Hat - Bow Island - Suffield

- Okotoks - High River - Claresholm

- Red Deer - Ponoka - Innisfail - Stettler
