A significant weather system is poised to roll across the region tonight and into tomorrow, and we could get 15 to 20 cm of snow by the time it’s over. Snowfall warnings are in effect for areas including Yorkton, Kamsack, Foam Lake, Swan River and Minnedosa. A low pressure system in the U.S moves just south of the border before entering Ontario tomorrow night. The storm will be short-lived, and should be out of the region tomorrow afternoon.
