The weather models were able to successfully predict last week’s snowstorm that brought this season’s first significant snowfall. Originally, the weather models had most of the snow falling to our south and east, but a bit of a northward shift in the trough of low pressure resulted in winter moving in and us receiving some much-needed moisture. The big questions now are whether winter is here to stay — and will we see more snow?
This forecast period will begin with an area of low pressure lifting northeastward out of north-central Manitoba, which may allow for some wraparound flurries to push southward on Wednesday into Thursday. As the low pulls off toward Hudson Bay, cool arctic air will push southward. After a bit of a warm-up ahead of this low early in the week, expect daytime highs to cool down to the -5 C range, with overnight lows falling to around -12 C. The cooler conditions will last until the weekend as weak arctic highs drift south-eastward in the northwesterly flow. Over the weekend an area of low pressure is forecast to track by to our south, with a trough of low pressure stretching northward. This low could bring a little light snow on Saturday and Sunday. Current indications are for only light accumulations.
To start the week of Nov. 22, the weather models are showing the cool air that pushed in behind the weekend low quickly being replaced by milder air being pulled northward by an area of low pressure forecast to develop over Alberta on Tuesday. This Alberta clipper should track quickly through our region, bringing with it another shot of snow. Due to the quick nature of this forecasted low, accumulations should be light. Temperatures will cool down a little bit behind the low, but there are still no indications of any big outbreaks of cold air at this time.
