Spinglike weather finally made an appearance over southern MB this week with the first double digit temperatures of the season in Winnipeg Wednesday (high of +10.4C), and almost 20C temperatures over the southwest RRV (19.3C in snowfree Morden) The mild temperatures have made a significant dent in the snowpack across southern MB, with most areas west of the Red River valley and south of the TransCanada now snow free. Here in Winnipeg, snowdepth at my location has dropped to 14 cm this morning after being at 40 cm just last weekend. Snowcover should continue to go down over the next couple of days as daytime temperatures remain above freezing.
But don't put away the snowshovels and boots just yet! Believe it or not, indications are that Winnipeg and much of southern MB will be seeing more of the white stuff this weekend, especially Saturday as a couple of disturbances track across the southern Prairies, while colder air flows in from the north. The first wave of snow is expected to spread over SW MB and along the US border Friday night into early Saturday, before another disturbance from central Saskatchewan brings a second wave of snow across the western Parklands into the Red River valley through Saturday, including Winnipeg. There is still a lot of uncertainty about how much snow will fall with these systems due to temperatures hovering near the freezing mark, but it's possible Winnipeg and the RRV could see 5-10 cm of snow Saturday, while some higher elevations of western MB may see 15 cm of snow or more. Colder air will follow in the wake of these systems with daytime highs remaining below freezing early next week, well below normal for this time of year (normal highs now +9c). Temperatures are expected to moderate by the end of next week with near normal temperatures again by next weekend. Until then, get ready for another taste of winter.. hopefully the last parting shot of the season!
