A progressive weather pattern shaping up will bring more variable weather conditions to southern MB over the next week, with a roller coaster pattern of temperature swings. After another frigid cold snap this week, it looks like we'll have a significant, albeit brief, warmup for Winnipeg and southern MB on Saturday as a low pressure system crosses just north of Winnipeg through the interlake area. This system will bring in some snow, with 2 to 5 cm possible generally south of the TransCanada, and higher amounts of 5 to 10 cm north of Winnipeg through the Interlake areas. Gusty south winds accompanying the snow will also produce blowing and drifting snow especially through the Red River valley with poor visibilities at times. As a result, be prepared for poor travelling conditions Saturday.
As for temperatures.. don't let that forecast high of 0C for Saturday fool you. Gusty southerly winds will make it feel considerably colder, especially in the morning when temperatures will still be in the minus teens, and snow and blowing snow will make it blustery. Temperatures will gradually moderate in the afternoon reaching minus 5 or so by late day. In the evening, winds will shift into the northwest, and we will briefly tap some milder air from the west with temperatures climbing towards the freezing mark Saturday evening, before cooling off again Saturday night. Temperatures are expected to drop to below normal values again for Sunday and Monday, but not as cold as the current cold snap. Another Alberta clipper is expected to bring moderating temperatures and some snowfall on Tuesday, before a trend towards milder temperatures (near to above normal) moves in by the end of the week. A roller coaster week coming up!
