A spring storm system developing over southern Saskatchewan on Monday night is forecast to spread a messy mix of wintery precipitation across much of southern Saskatchewan overnight into Tuesday. Precipitation will start off as rain tonight over southwest Saskatchewan spreading east overnight. As it does, it will encounter colder air over Manitoba, causing rain to change to freezing rain from the Quill Lakes area to Yorkton. Freezing rain will then change to snow Tuesday morning as colder air is drawn into this system, with 5 to 10 cm possible by Tuesday evening over east central regions of Saskatchewan.
In the southwestern corner of the province, precipitation will start off as rain as the system moves over southwest Saskatchewan tonight . As the system tracks east Tuesday, winds will shift into the north behind the system Tuesday morning and become quite strong with gusts to 80 km/h over southwest Saskatchewan, and possibly 90 km/h over the Cypress Hills. These winds will draw in colder air causing rain to change to snow Tuesday morning with poor visibilities at times. Snowfall amounts of 5 cm are possible for most areas with 10 cm or more possible over the Cypress Hills. Conditions are expected to improve by late Tuesday afternoon as the storm system moves into North Dakota.
