Winter arrives in a big way this week. An early winter storm combined with snow squalls could bring over 30cm of snow by the time we head into this weekend. The wildcard is that temperatures will be a degree or two above freezing each day, and the ground still isn't frozen - so how much, if any, will melt? It's likely a good bet to have the snowblower ready to go.
Monday will be cloudy, with snow starting early afternoon as temperatures max out near 1°C. The snow intensifies in the evening and continues overnight, bringing 10-15cm of accumulation by Tuesday morning.
We will see some breaks in the clouds on Tuesday as daytime highs climb to 3°C. Later in the day, northwest winds will bring scattered snow squalls that could bring 2-5cm of new snow.
Wednesday will be mostly cloudy with the ongoing risk of a light flurry as temperatures struggle to reach 2°C. Thursday will be overcast with a chance of flurries and daytime highs near 1°C.
Heavier snow squalls may arrive on Friday, bringing another round of accumulating snow that could continue through the weekend.
