Winter’s Grip Loosens as Temperatures Rise
Thunder Bay starts cold at -13°C but warms to +1°C today. Monday brings sunshine and 7°C before snow returns midweek. A mix of winter and early spring ahead!
Thunder Bay wakes up to a mostly cloudy morning with a current temperature of -13.3°C. The humidity sits at 67%, and with calm winds, it may not feel too harsh—until you factor in this morning’s wind chill of -26°C. The barometric pressure is at 102.3 kPa but falling, hinting that a shift in weather is on the way. Visibility remains excellent at 32 km, making for a clear view despite the clouds.
Sunday: Cloudy Skies But Warmer Air Arrives
Today will stay mainly cloudy, but with light winds up to 15 km/h, the temperature will climb to +1°C—a welcome improvement from the bitter morning chill. The UV index is 2 (low), so while sunglasses might not be essential, the bright sky could still cause some glare off the snow.
Tonight, partly cloudy conditions will give way to clearing skies late this evening. The wind will stay light at up to 15 km/h, and temperatures will drop to -11°C. Wind chills will make it feel like -4°C this evening and -16°C overnight, so it’ll be another cold night, but not nearly as frigid as earlier in the week.
Monday: A Beautiful Break from Winter
Monday brings plenty of sunshine and another bump in temperatures. With light winds staying at 15 km/h, the high will reach a surprisingly warm 7°C—a definite sign that March is teasing spring. However, the morning will still be cold, with a wind chill of -14°C before things warm up. The UV index rises slightly to 3 (moderate), so some sun protection might be needed for those spending time outdoors.
Monday night sees increasing cloudiness with a low of -5°C, setting up for a return to wintry conditions later in the week.
Tuesday & Beyond: A Snowy Pattern Returns
Tuesday will be cloudy with a 40% chance of snow, and temperatures will still manage to reach +1°C. By nighttime, periods of snow are expected, with temperatures dropping to -6°C.
Wednesday continues the snowy trend, with periods of snow and a high of -2°C, before cooling down further at night with cloudy periods and a 30% chance of flurries, along with a low of -13°C.
Wardrobe Advice: Layers for the Changing Weather
For today, a warm coat, gloves, and a hat are still a must, especially in the morning when the wind chill is severe. By Monday afternoon, a lighter jacket might be enough, though you’ll want to keep winter gear handy for the chilly mornings. As snow returns by midweek, waterproof boots and warm layers will once again be essential.
