Environment Canada has issued a winter storm warning for the eastern part of the province including Yorkton, Melville, Moosomin, Grenfell and Kamsack regions.
A low pressure system moving eastward along the international border in Saskatchewan will rapidly intensify as it tracks into Manitoba Monday. Snow, heavy at times, will begin Monday morning and continue through Wednesday. Total amounts of 15 to 30 cm is expected over the warned area, with the highest amounts most likely over the Parkland Region. Meanwhile, northerly winds gusting to 50 or 60 km/h will develop Monday night or Tuesday over most areas. Visibilities will be significantly reduced at times in snow and blowing snow for most of Tuesday and into Wednesday as well.
This will be followed by cold arctic air sweeping in with lows below -20 degrees Celsius expected by the end of the week accompanied by wind chill values in the -30 to -35 range.
Meanwhile, the rest of southern Saskatchewan is under a blowing snow advisory.
Blowing snow will begin Sunday night and last through Monday across much of southern Saskatchewan including Regina.
A low pressure system developing in the southwestern corner of the province will track eastward along the international border tonight. Many areas along and south of the Trans-Canada corridor can expect to see 5 to 10 cm of fresh snow through Monday as the system passes over. In its wake, northwesterly winds of 40 gusting to 60 km/h develop as a cold arctic airmass floods over the province.
Visibilities will be reduced in snow and blowing snow beginning this evening in the southwest expanding eastward to the Manitoba border by Monday morning. The winds and blowing snow are expected to last through the day Monday before the wind gradually begins to ease on Tuesday.
