THUNDER BAY – WEATHER DESK – A deep Arctic chill is locked over Northern Ontario this Monday morning, keeping temperatures well into the minus 20s and pushing wind chills into the -30s (and colder at times). Snow isn’t widespread everywhere at once, but light snow, flurries, and pockets of blowing snow will cycle through the region—enough to create slick travel and reduced visibility in bursts.

Wardrobe Recommendations

This is serious cold across all four communities:

Wear thermal base layers, an insulating mid-layer (fleece/wool), and a windproof parka.
Mitts beat gloves for warmth; add hand/foot warmers if you’ll be outside for more than a few minutes.
Protect your face: balaclava/neck gaiter + toque, and consider ski goggles if snow picks up.
For travel between communities: pack an emergency kit (blanket, food, charger, booster cables) and keep fuel topped up—cold drains batteries fast.
