THUNDER BAY, Ont., Nov. 2, 2026 — Thunder Bay and Kakabeka Falls will see rain develop Monday afternoon, followed by a mild, wet night and lingering showers through Wednesday.

Wet pavement, pooled water and reduced visibility are the main travel concerns. The evening commute may deteriorate as steadier rain arrives.

Weather trivia: One millimetre of rain equals one litre of water spread over each square metre. A 20-millimetre rainfall therefore deposits about 20 litres per square metre.
