Northern Ontario: Snowfall Outlook for Thursday, December 9, 2021

Forecast Discussion

A developing system is expected to slide across Northern Ontario throughout the day on Thursday bringing with it the threat of widespread accumulating snowfall. General amounts from this system won’t be that impressive with around 6-12cm before the end of the day on Thursday. This includes locations such as Sioux Lookout, Armstrong, Fort Hope, Geraldton and Kapuskasing. However, locally higher snowfall totals are expected around the Lake Superior shoreline including Thunder Bay, Marathon and Wawa where some lake enhancement could result in accumulation reaching somewhere around 12-20cm. Blowing snow will also be an issue with 50-70km/h wind gusts particularly during the afternoon hours. Be sure to take your time out on the roads if you’re travelling in the affected regions. The heavy snowfall will affect Northeastern Ontario overnight into Friday morning which will be covered in Friday’s outlook.
