FORECAST UPDATE - FEB. 25 @ 9:30 AM
The Prairies will finish the weekend with some fresh snow, courtesy of a fast-moving Clipper that will begin to move into Alberta overnight tonight. The snow will spread eastward throughout Sunday and most of Monday before making its way into Northern Ontario.
A large swath of Alberta can expect 10-20cm of snow by Monday afternoon with Edmonton and areas to the west being hit the hardest. This region will see snowfall totals approaching 20cm and possibly exceeding that amount locally. Most of this accumulation will occur in the late evening and overnight Sunday before starting to taper off Monday morning. Around Edmonton, the snow is expected to begin in the mid-afternoon and continue until mid- to late-morning on Monday.
The snow will cross into Saskatchewan Sunday evening and will spread across Central and Southern portions of the province through the overnight and early morning hours Monday. The heaviest snow will be concentrated to a line across Central Saskatchewan with a drop in snowfall accumulations moving northward and southward. Locations from Lloydminster, though Saskatoon to the Manitoba border can expect 10-15cm of snow throughout the day on Monday.
Things don’t start in Manitoba until early Monday and with the heaviest snow expected for Southern Manitoba as the Clipper continues its east-southeastward trajectory. The swath of 10-15cm will continue into the province from Saskatchewan but will only reach as far as across the Interlake Region because the back half of the storm starts to fall apart, and the snow begins to dissipate through Monday afternoon. Winnipeg, in particular, can expect the snow to be fairly short-lived and last less than 12 hours beginning after midnight Monday and continuing until mid-morning, resulting in less than 10cm of snow.
Temperatures ahead of the snowfall will be quite mild, with most of the Prairies reaching highs approaching or surpassing 0°, but they will rapidly plummet down to the negative double digits with the passage of the Clipper. Some areas could even see temperatures as low as -30° Tuesday night. This short blast of cold is expected to last for a couple of days before we return to more seasonal temperatures mid-week.
