Thunder Bay – Weather – Light snow is drifting through Thunder Bay this Wednesday morning, with a brisk west-northwest wind keeping it feeling colder than the thermometer suggests.

The good news: skies brighten later today as conditions trend sunnier this afternoon. The not-so-good news: the cold hangs on, and wind chills dip back into the -30s overnight, keeping frostbite risk in the picture.

Wardrobe Recommendations

• Dress in layers (thermal base layer + warm mid-layer + windproof outer layer)

• Mitts, a warm toque, and a face covering help a lot when wind chills slide into the -20s and -30s

• Insulated boots with traction—light snow plus cold often means polished ice on sidewalks and parking lots

• If you’re driving outside the city: keep a winter kit (blanket, charger, booster cables) because cold is hard on batteries

Weather Trivia

Thunder Bay’s winter weather can flip fast when winds shift. Even light lake-influenced moisture can squeeze out flurries, and a small increase in wind speed can make the same temperature feel 10 degrees colder in a hurry.
