Get ready for a winter blast! A dramatic shift in weather is about to hit Southern Manitoba, turning the recent Spring-like temperatures into a distant memory.
Environment Canada has issued a Snowfall Warning, with a potential 15-20cm of snow on the way. But here's where it gets tricky: a Freezing Rain Warning is also in effect for specific regions. The Manitou, Pilot Mound, Killarney, Boissevain, and Melita areas should brace for freezing rain on Tuesday afternoon, transitioning to snow later that night. And the Pembina and Red River Valleys might not be spared either, with a risk of freezing rain on Tuesday afternoon.
Chris Sumner, CMOS Accredited Weathercaster, paints a vivid picture: "Old Man Winter isn't done with us yet. After two more days of mild weather, a major winter storm will arrive on Tuesday night." Temperatures will drop significantly, with highs of 0 to +2 degrees on Monday and Tuesday, and the rest of the week feeling like a true winter wonderland.
The storm's origin story is fascinating. A moist airmass from the Pacific, originating off the California coast, is set to collide with colder air over the Prairies. This clash will result in a Montana low-pressure system, bringing a prolonged period of heavy, wet snow.
But there's a twist! Sumner reveals, "The exact path of the low-pressure system is still uncertain." A more northern track could bring warmer air and more rain/freezing rain initially, reducing overall snowfall. Conversely, a southerly track would mean an earlier transition to snow and potentially higher snowfall totals.
So, how much snow can we expect? Sumner predicts the highest accumulations in Western Manitoba and the Parkland region, but the Red River Valley and Southeastern Manitoba won't be spared either. He advises, "Prepare for at least 15cms of heavy, wet snow in the Pembina and Red River Valley by Thursday afternoon." And it could be even more, especially near the Manitoba escarpment, where geography may intensify snowfall rates.
Blowing snow and reduced visibility will further complicate matters, with gusty easterly winds up to 50km/h on Tuesday afternoon and evening. Sumner warns, "Travel conditions will become treacherous as the snow and winds intensify."
The storm is expected to persist through Wednesday and into Thursday morning, with cooler temperatures settling in after its departure.
And this is the part most people miss: despite the challenges, Sumner describes it as a "traditional Spring snowstorm," emphasizing the heavy, wet snow and its extended duration.
