Northern Ontario: Snow Squall Outlook for Saturday, December 4, 2021

Forecast Discussion

Snow squalls are expected to develop early Saturday morning east of Lake Superior and continue throughout the day. This will bring rapid snowfall accumulation and near-zero visibility to the Wawa and Sault Ste. Marie area. Accumulation by the end of Saturday could locally approach the 20-25cm mark with more general amounts between 10-20cm. The snow squall activity will come to an end late Saturday as an approaching winter storm shuts off the lake effect snow. More details on that winter storm are coming soon.
