Northern Ontario: Fall Weather Hazards Outlook for Wednesday, October 20, 2021

Forecast Discussion

Colder air is expected to flow into the extreme northern part of Northern Ontario around Hudson Bay during the early part of Wednesday with temperatures remaining near the freezing mark throughout the day. Combined with a weak low-pressure over Hudson Bay will provide the potential for some flurries and wet snow beginning Wednesday morning and continuing through the day. Limited accumulation if anything at all is expected with at most around 5cm of accumulation for locations such as Fort Severn and Winisk. This may linger into early Thursday and reach even further south into Northeastern Ontario, but this will be covered in Thursday’s outlook.
