A Mild Start with Flurries & Some Sunshine
Thunder Bay weather: Flurries taper off today with a high of +3°C. Freezing drizzle and fog possible overnight. Rain or snow midweek before a cold snap returns
Thunder Bay is waking up to light snow and a temperature of -2°C this morning. The humidity is sitting at 97%, meaning the air is damp and heavy. Winds from the east at 10 km/h are making it feel like -5°C with the wind chill. The barometric pressure is at 100.7 kPa and rising, signaling some shifts in the weather ahead. Visibility is at 13 km, which is decent but could be reduced in lingering snow.
Periods of light snow will taper off early this morning, leaving behind mainly cloudy skies and a 30% chance of flurries. By this afternoon, skies will break into a mix of sun and cloud, and temperatures will climb to +3°C. Winds will stay light, reaching 15 km/h at most. The UV index sits at 1 (low), so while the sun may peek through, it’s nothing to worry about.
Tonight: Flurries, Freezing Drizzle & Fog
Skies will remain partly cloudy, but a 40% chance of flurries develops overnight, along with a risk of freezing drizzle—so icy conditions are possible by morning. To add to the mix, fog patches will develop after midnight, which could reduce visibility on the roads. Winds will remain light, and temperatures will drop to -7°C, with the wind chill making it feel like -10°C.
Midweek: A Balancing Act Between Snow & Rain
Wednesday, February 26, will start off cloudy with a 40% chance of flurries, but by midday, those flurries could switch to rain showers as temperatures rise to +5°C. There’s also a risk of freezing drizzle in the morning, making for potentially slick roads early on. Any fog patches from overnight will dissipate in the morning. Winds will stay light at 15 km/h, and the UV index will be 2 (low).
By Wednesday night, the chance of precipitation increases to 60%, with more flurries or rain showers possible, and temperatures holding at -1°C.
