Wardrobe

Use waterproof footwear and a rain shell through Wednesday, especially from Armstrong to Nipigon. Drivers should keep an extra dry layer in the vehicle. Add gloves and a warmer layer Thursday as temperatures drop and rain may mix with snow.

Weather trivia

Fog forms when air cools to its dew point and water vapour condenses into tiny suspended droplets. That is why visibility can stay poor even after steady rain ends.
