Thunder Bay – Weather – Thunder Bay is back in a “quiet snow” pattern this morning: light snow, reduced visibility, and a falling barometer as the next system brushes through. The bigger story is Friday’s quick warm-up to around +3°C, paired with strong winds (gusts up to 70 km/h) that could make roads slick and messy as snow mixes with flurries or rain showers.

Wardrobe Recommendations
-
Today (snow + wind chill near -20): Winter parka, warm mid-layer, insulated boots, and mitts. With steady flakes and 6 km visibility, add a hat + neck warmer for comfort.
-
Friday (milder but windy + mixed precip): Think waterproof and windproof—a shell over layers, waterproof boots, and gloves that can handle wet snow/rain. Secure hats/hoods: gusts could be strong.
-
Friday night into Saturday: Keep the heavy gear handy—temperatures drop fast again after the warm-up.
Weather Trivia
For Thunder Bay (1991–2020 climate normals), the average February high is about -5.2°C and the average February low is about -18.3°C—so Thursday’s forecast high near -5°C is right on brand for late February. And for perspective: February’s extreme minimum in that dataset is -40.6°C (Feb 1, 1996).
