Parts of Alberta and southern Saskatchewan will get an early taste of winter on Tuesday as temperatures drop towards the freezing mark.

The snow has already made its debut in Alberta back in October, but this could be the first snowfall event of the season for southern Saskatchewan.

DON’T MISS: Look up! What’s going on in the November night sky?

Chilly northwesterly air will sink into Alberta on Tuesday, following a low-pressure system sweeping across the province throughout the day.

As temperatures drop to the freezing mark, a messy mixture of rain and flurries are forecast to impact travel between Edmonton and Medicine Hat. The ratio of rain to snow, as well as temperature, will ultimately determine how much snow stays on the ground. Up to 3 cm of snow accumulation is possible if temperatures drop to or below 0°C.

The snowy potential will be greater along the Alberta-Saskatchewan border on Tuesday morning and evening, when the temperatures will be at their chilliest.

10-15 cm of snowfall is possible along the Trans-Canada Highway between Medicine Hat and Swift Current, Sask. While rainfall will remain limited in this region, the heavy snow will still make the major highway slick, so travellers should prepare for winter driving conditions.
