A strong winter storm system passing through the northern Plains has spared much of southern MB from significant snow or blizzard conditions, but not from bitter cold temperatures and extreme windchills. The storm, centered over southern Minnesota this morning, has brought snow and blizzard conditions to much of North and South Dakota overnight which will continue into today. Areas of southern MB near the ND/MN border from Emerson to Sprague will still see some snow with this system today (perhaps 2-4 cm), with locally poor visibilties in blowing and drifting snow especially in the southern Red River valley, but blizzard conditions are expected to remain south of the border.
The main story over the next few days will be the bitter cold, with strong winds today producing extreme windchills of -40 to -45. At these values, frostbite is possible within 10 minutes. Winds will ease somewhat Monday and Tuesday, but with bitter cold temperatures continuing (-25 to -35C), wind chills will be an issue through much of the week.
