Thunder Bay – Weather – After a day where Thunder Bay was the warmest spot in Ontario and then plunged into a deep freeze, we now have a Saturday that calls for mittens for the little ones.
It’s a chilly and calm start this morning under clear skies with high pressure. The air feels crisp and cold, and the wind makes it feel like frostbite is a real concern.
Cloud cover will increase later today as light snow is expected to arrive late tonight into tomorrow morning.
Clouds will thicken, bringing light snow starting late this evening. Winds may reach up to 15 km/h. Expect lows around -16°C (3°F) with wind chill close to -22 tonight. Sunday, Feb 8:
It’ll be cloudy with a 40% chance of flurries and winds up to 15 km/h. The high will be around -6°C (21°F). Wind chills are expected near -19 in the morning and improve slightly to about -10 in the afternoon. Sunday night will remain cloudy with a 60% chance of flurries, lows close to -9°C (16°F). Monday, Feb 9:
Expect more cloudiness with a 60% chance of flurries; highs near -2°C (28°F). Monday night looks less active: there’s only a 30% chance of flurries, lows around -7°C (19°F). Note on trends: Temperatures should warm up from today’s deep cold towards “near-freezing during the day,” but we can still expect clouds and flurries hanging around.

Wardrobe Recommendations
This morning (with wind chills between -31 and -32): wear an insulated parka along with thermal base layers plus fleece mid-layers; lined snow pants are recommended if you’ll be outside longer than just running errands. Take care of your skin: use mitts instead of gloves for warmth; wear a toque or hat along with either neck gaiters or scarves; consider wearing something over your face if you’re waiting for public transport or walking your dog since frostbite risk increases quickly when skin is exposed. Footwear should include insulated boots paired with wool socks; think about adding traction cleats if sidewalks get icy after tonight’s snowfall. As we move into tonight and Sunday: keep an ice scraper handy along with some windproof clothing because light snowflakes can sting when there’s even just a slight breeze.Weather Trivia
