Northern Ontario: Snowfall Outlook for Tuesday, February 22 - Wednesday, February 23, 2022

Forecast Discussion

A snowstorm is set to take aim at Northeastern Ontario starting early Tuesday morning and continuing into Wednesday. Sleet and freezing rain are possible around the Georgian Bay shoreline including Sudbury and North Bay which would help reduce the potential snowfall totals.

A fairly expansive zone that includes Thunder Bay through much of Northeastern Ontario like Maraton, Chapleau, Timmins and Cochrane will see around 20-30cm of snow from this storm. Locally higher totals closer to 35cm or even 40cm can’t be ruled out either. Accumulation will drop off further to the north where less moisture will be present and to the south where mixing is possible. The Sudbury and Kapuskasing region can expect between 10-20cm of snow. While North Bay should see around 5 -15cm of snow along with several hours of heavy sleet or freezing rain.

Blowing snow will also be an issue with wind gusts ranging from 40-60km/h making for difficult driving conditions. We should see an improvement after Wednesday morning as the system moves out of the region. If possible, try to avoid travel until Wednesday as it’s quite possible that this storm will lead to highway and road closures through Northeastern Ontario.
