Cool and Cloudy Start to Saturday in Thunder Bay
Thunder Bay faces a cold and mostly cloudy weekend, with wind chills as low as -27°C. Expect a mix of sun and flurries, with bitterly cold nights ahead
Thunder Bay is waking up to a mostly cloudy morning, with a temperature of -15°C at the airport. The humidity sits at 84%, giving the air a crisp, wintery feel, while a west wind at 11 km/h is driving the wind chill down to -21°C. The barometric pressure is at 102.3 kPa, suggesting stable but chilly conditions ahead. If you’re heading out early, don’t be fooled by the cloud cover—it’s still bone-chillingly cold!
Saturday: Cloudy and Cold with Increasing Winds
The sky remains mainly cloudy throughout the day, with winds shifting to northwest 20 km/h by early afternoon. The high will reach -8°C, but the wind chill will make it feel like -24°C this morning and -14°C this afternoon. While the UV index remains low at 1, it’s still a good idea to wear sunglasses if the sun peeks through the clouds.
Tonight, skies will partly clear, but temperatures will plunge to -20°C. With light winds up to 15 km/h, the wind chill will feel like -27°C overnight. If you’re venturing out, make sure to bundle up—exposed skin can freeze in minutes!
Sunday: Brighter Skies, but a Bitter Morning
Sunday will bring a mix of sun and cloud, offering a bit of brightness to break up the wintry gloom. However, the wind chill will be brutal in the morning, dipping as low as -27°C. By the afternoon, the high will reach -10°C, with the wind chill improving slightly to -15°C. Light winds up to 15 km/h won’t provide much relief from the cold, so dress warmly.
Sunday night will be clear, with a low of -21°C. A perfect night for stargazing—if you can stand the cold!
Monday & Tuesday: A Mix of Sun, Flurries, and Frigid Nights
Monday brings another mix of sun and cloud, along with a 30% chance of flurries. The high will be -10°C, so still cold, but manageable. Monday night looks cloudy with a continued 30% chance of flurries, with a low of -22°C.
Tuesday is shaping up to be sunny but significantly colder, with a high of only -15°C. The real story? Tuesday night’s deep freeze, with clear skies and a low of -28°C. That’s “car battery won’t start” kind of cold, so prepare accordingly!
What to Wear? Bundle Up or Stay Indoors!
With wind chills dropping to -27°C, proper winter gear is essential. A thermal base layer, an insulated mid-layer, and a windproof outer shell will help keep the cold at bay. Don’t forget a thick toque, insulated gloves, a scarf, and warm winter boots—frostbite can happen quickly in these conditions. If you’re out in the evenings, hand and foot warmers are a great way to keep extremities from turning into icicles.
