A winter storm warning has been issued for parts of southwestern Saskatchewan.
Environment Canada says the storm is expected to bring heavy, wet snow throughout the day Monday.
Accumulations approaching 30 centimetres are anticipated along the Trans-Canada Highway in the area from west of Swift Current to the Alberta border, including the Cypress Hills area.
The snow will combine with northerly winds gusting to 80 kilometres an hour, resulting in white-out conditions at times. Highway closures are likely in the area, and motorists are advised to postpone travel until the storm has passed, the weather agency said.
An additional 15 cm of snow is expected Monday night before the snowfall gradually tapers off Tuesday.
Further east and north, temperatures are expected to remain above zero, with precipitation falling as rain instead of snow.
Significant rainfall accumulations are possible, with 40-50 millimetres forecast in a band stretching between Saskatoon and Regina. Rainfall warnings were in effect for some regions of southern Saskatchewan.
