THUNDER BAY – WEATHER – The weather in Thunder Bay for mid-October is expected to be cool, with frosty mornings, sunny afternoons, and clear skies throughout much of the forecast period. Temperatures will vary significantly between the crisp mornings and warmer afternoons, with a chance of early flurries on Tuesday.

For those commuting in the mornings or spending time outdoors, it’s important to bundle up as wind chills will make it feel colder than the actual temperature. Walking the dog in the early morning or later evening means gloves for you! Maybe even a hat or toque.

As frost forms at night, road conditions may become slippery, so drivers should take extra precautions.
