The Pembina and western Red River Valley are waking up Monday to yet another snowy, icy and slushy mess to contend with after 10 to 15 cm's of snow fell throughout Easter Sunday. Periods of light snow are expected to end Monday morning, with sunshine returning by early afternoon.
"Many of these areas received between 15 and 35cms of snow, already, during last week's Colorado low, with clean up still happening in some communities," said CMOS Accredited Weathercaster Chris Sumner. "This Montana clipper is just adding insult to injury for many Southern Manitobans who have had more than their fill of Old Man Winter this season."
As of 6:30 a.m. Monday, highways throughout the region are snow and ice covered, with some blowing and drifting snow. Northerly winds are expected to top out in the 30 km/h range Monday, so significant blowing snow and reduced visibility should not be a concern.

According to Sumner, the general trend of it feeling more like mid-January than mid- April will continue this week.
"Unsettled conditions, and the likelihood of another taste of winter or two, are showing up in the forecast models," he explained. "After high pressure builds in Monday, giving us a brief return to sunshine for the afternoon and part of Tuesday, an Alberta clipper will quickly move across the southern Prairies Tuesday night and Wednesday. We're not expecting this low pressure system to be a significant precipitation maker, but we can expect the classic clipper characteristics of breezy conditions and a bit of snow. At this point, it's looking like up to 5cms of snow possibly, with southeasterly winds between 40 and 50km/h likely. This fast moving system will be out of our region by Wednesday night, with a partly sunny day expected Thursday."
Sumner added, what has his attention is set to arrive later this week, another Colorado low which is appearing in the forecast for this coming weekend.
"Similar to what we saw last week, we're seeing agreement at a relatively early stage across a number of forecast models that a potentially significant system will move through the Dakotas and Minnesota toward northwestern Ontario during the Friday through Monday (April 22nd to 25th) timeframe," said Sumner. "At this point, it's way too early to say what the exact track will be, and therefore which parts of the province may be most impacted. What I can say, is this system has the potential to be moisture packed, just like last week's storm, and that may mean another round of significant precipitation depending on how exactly this storm forms and then moves across the northern U.S. plains. At this point, it's safe to say much of Southern Manitoba will see snow or rain, at some point, over the course of those four days. How much, for how long and exactly where is still to be determined. I would encourage you to keep an eye on the forecast as this Colorado low develops, because it's quite likely it will bring impactful conditions to the region."
Meanwhile, temperatures will continue to be well below average this week, with highs between +2 and +4 for the next several days. Averages for this point in April are 13 daytime and 0 overnight.
