THUNDER BAY – WEATHER – Thunder Bay woke up to light snow, low visibility, and strengthening southeast winds as an Alberta Clipper pushes through Northwestern Ontario.
Environment Canada has a Yellow Warning – Snowfall in effect, with 15–25 cm possible and blowing snow reducing visibility at times—especially on open stretches of Highway 11 and Highway 17.
Today’s Weather Overview
At 6:18 AM EST (Thunder Bay Airport), conditions were light snow with the temperature at -8.2°C—mild enough to jokingly call Thunder Bay “Ontario’s hot spot” compared to colder inland communities. Winds were SE 27 km/h gusting 44 km/h, pushing the wind chill to -17, and visibility was down to 2 km. Pressure sat at 100.6 kPa and falling, a classic sign the system is still in control.
What happens today (Tuesday)
Environment Canada’s forecast calls for snow at times heavy with local blowing snow, then ending this afternoon, followed by cloud and a 60% chance of flurries. The local amount is about 15 cm, but the warning notes total snowfall of 15–25 cm in the area, with southerly gusts up to 60 km/h capable of creating sudden whiteouts in exposed locations.
Travel impacts: If you’re driving, expect the toughest stretch this morning into early afternoon. Plan extra time, keep your headlights on, and assume conditions can drop fast—especially outside city limits.

Tonight (Tue night): Mainly cloudy with a 60% chance of flurries. Winds turn NW 30 km/h gusting 50, low -13°C(wind chill near -21 overnight).

Wardrobe Recommendations
-
This morning/early afternoon: Full winter kit—insulated parka + windproof outer layer, warm mitts, toque, and a neck warmer. With blowing snow, glasses/goggles help a lot.
-
Driving today: Waterproof boots and traction-friendly footwear (slushy compact snow near intersections gets slick fast). Keep spare gloves/hat in the car.
-
Tonight/Wed: Switch back to warmth-focused layers—winds go northwest and it feels sharper again.
Weather Trivia
Thunder Bay’s seasonal normals for late February are about -3°C (daytime high) and -15°C (overnight low)—so while today’s snow is messy, the temperature is actually close to “typical.” Also, daylight is returning: sunrise 7:48 AM / sunset 6:33 PM today.
