Major Arctic blast moving in Sunday....
Another Alberta clipper gave us more snow today with 5-6 cm reported across much of Winnipeg and southern MB. But Mother Nature is saving her worst for the weekend, as a bitterly cold Arctic blast will be moving in by Sunday on the heels of another snow bearing system. This system will be moving into Montana on Saturday then into the Dakotas on Sunday spreading another area of snow across southern MB over the weekend. Another 5-10 cm of fresh snow is expected Saturday into Sunday with this system, on top of the 10 cm that has fallen this week. The problem will be Sunday afternoon and evening behind this sytem as increasing northerly winds gusting to 60 or 70 km/h drives in bitterly cold Arctic air producing poor visilities in blowing and drifting snow. In fact, blizzard conditions are possible over southern MB Sunday afternoon through Sunday night especially over the Red River valley. In addition, temperatures will be plunging into the minus 25 to minus 30 range, with wind chills in the minus 40s. All in all..a nasty end to the weekend with a very cold start to the week ahead.
