Chilly Morning in Thunder Bay with Snow on the Horizon
Thunder Bay starts off sunny but frigid today before snow moves in tonight. Winds will pick up Thursday, bringing a blustery chill. Stay warm and bundled up!
Thunder Bay wakes up to a crisp and cold morning, with the temperature sitting at -22°C as of 7:00 AM at the Thunder Bay Airport.
A west-northwest wind at 8 km/h makes it feel even colder, bringing the wind chill down to a frosty -29.
The humidity sits at 71%, and the barometric pressure is at 103.3 kPa, though it’s on a downward trend. Visibility is excellent at 24 km, but the cold is no joke—bundle up, as frostbite is a real risk this morning.
Today’s Forecast: Sun with a Side of Frostbite
Expect a bright start to the day with sunshine giving way to a mix of sun and cloud as the morning progresses. Winds will remain light, reaching up to 15 km/h.
The high for today will be a relatively “warm” -9°C, though wind chills will keep things feeling much colder, especially this morning at -28. By the afternoon, the wind chill will ease slightly to -12. The UV index remains low at 1, so while sunglasses might be handy for the glare, sunscreen won’t be a top priority.
Tonight: Snow Moves In
Clouds will take over tonight, and snowfall is expected to begin late in the evening, with an accumulation of 5 to 10 cm by morning. Winds will shift to the south at 20 km/h before dawn, and temperatures will hold steady at a low of -10°C. Wind chills will make it feel closer to -14, so if you’re heading out late, expect a snowy and chilly night.
Thursday: Windy with More Snow
Thursday will bring more snowfall, though lighter than tonight, with around 2 cm expected. The bigger story will be the wind, as a south wind at 20 km/h in the morning will shift to a gusty northwest wind of 30 km/h, gusting up to 70 km/h. That wind shift will drive temperatures downward, dropping to -13°C by the afternoon. The wind chill will make it feel like -13 in the morning and a bitter -23 by the afternoon. Hold onto your hats—it’s going to be blustery!
Thursday Night: Chilly with a Chance of Flurries
The night will see cloudy periods with a 40% chance of flurries. The low will dip to -14°C, so another cold night ahead.
Friday and Beyond: A Brighter, Colder Outlook
Friday brings a mix of sun and cloud with a high of -9°C, a relatively milder day compared to Thursday. By nighttime, the skies will clear, but with clear skies comes a sharp drop in temperature, plunging to -22°C.
Wardrobe Recommendations
Layers are your best friend today! A thick winter coat, thermal base layers, gloves, a hat, and a scarf are essential to protect against the wind chill. If you’re out for extended periods, frostbite is a real concern, so cover up as much as possible. If you’re heading out tonight, snow boots will be a must as the snowfall begins to accumulate.
