Some people in southwest Saskatchewan may want to dig out the snow shovel again.

Environment Canada has issued a snowfall warning saying a low-pressure system over Montana will bring heavy snow to the region with 25 centimeters possible by Friday morning.

Along with heavy snowfall, there will be a risk of freezing rain with this system Thursday into Friday.

While that warning is in effect for the Shaunavon, Maple Creek, Val Marie and Cypress Hills region, a special weather statement is in effect for Swift Current, Gull Lake, Leader, Herbert and Lucky Lake regions.

A cool, northerly flow will cause temperatures to drop rapidly Wednesday night. Precipitation will start as rain overnight on Wednesday, but as temperatures drop to just below zero by Thursday morning, the rain will transition to wet snow. At the onset of the snow, most will melt once it hits the ground. However, snow may be coming down quite heavy on Thursday, allowing snow to accumulate quickly. Current guidance on how much snow will accumulate on the ground is highly variable.

There is also a risk of freezing rain Thursday afternoon and overnight, specifically from Shaunavon to Swift Current and eastward.
