The current snow storm in parts of Saskatchewan will reach it’s full potential tomorrow.

Environment Canada has upgraded the Winter Storm Watch to a Snowfall Warning – covering a large portion of the south, southeast, and east-central areas of the province.

The federal weather agency says up to 10 to 20 cm of snow and periods of blowing snow will begin tomorrow morning. The snowfall will continue into Thursday.

Environment Canada Meteorologist Terri Lang says the rain-snow mixture we received earlier today was just a sample size of what’s to come.

“Because the temperature is so close to freezing, we are getting this flow up from the south, which we know is a warmer airmass and can hold a lot more moisture,” Lang said. “The system itself is really unstable, meaning there’s a lot of movement in the clouds, so we are expecting heavier amounts with this wet, heavy snow. Add in winds gusting as high as 70 to 80 kilometres per hour, and you’re looking for a real messy system.”

Lang says the largest snowfall amounts will be located in the southeast, especially around Weyburn, Estevan and Carlyle of up to 40cm, but admitted it can be hard to track accumulation due to the temperature close to zero.

Environment Canada says the rapid snowfall may make travel difficult and reduce visibility in some areas.
