Northern Ontario: Fall Weather Hazards Outlook for Thursday, October 21, 2021

Forecast Discussion

UPDATE (Wed. PM): There are no changes to our initial forecast although the rain/snow mix for Northeastern Ontario doesn’t appear as widespread in the latest data so locations like Sudbury and Elliot Lake might not see any snow.

Scattered flurries over regions near Hudson Bay will spread further south on Thursday to include locations like Sandy Lake, Fort Hope, Kapuskasing and Cochrane. Limited accumulation is expected with at most a few centimetres of accumulation. In addition to this, a system will track through the Great Lakes bringing heavy precipitation mostly in the form of rain. However, during the early morning hours on Thursday, there might be some snow that mixes in with the rain on the far northern edge of the system as it affects the Elliot Lake, Temiskaming Shores and Sudbury area. With temperatures near the freezing mark, we don’t expect any significant accumulation although it could result in some slushy road conditions.
