Thunder Bay – Weather – Thunder Bay is in cleanup mode this Thursday morning after the Alberta Clipper pushed through the region. With the mix of wet snow and freezing rain there will be slippery sections on many area roads and sidewalks.
The city is not under an active weather alert, but the forecast still carries a few leftover hazards, including a 40 percent chance of flurries, a risk of freezing rain early this morning, and northwest winds gusting to 50 km/h.

Today’s Weather Overview
As of the 6:00 AM EDT observation you provided, Thunder Bay was sitting at 0.8°C under cloudy skies, with west winds at 21 km/h, 90 percent humidity, and 24 km visibility. That is a much milder start than the last couple of mornings, but it is still unsettled enough to keep conditions feeling raw and changeable.
Environment Canada’s current forecast says a few rain showers or flurries will end early this morning, then the city will stay mainly cloudy with a 40 percent chance of flurries. There is also a risk of freezing rain early this morning, while northwest winds increase to 30 km/h gusting to 50. The daytime high is expected to reach 3°C.
Tonight and the Next Three Days
Tonight turns quieter but colder. Thunder Bay is expected to stay mainly cloudy, with northwest wind at 20 km/h becoming light this evening and a low of -5°C. The overnight wind chill will be near -9.
Friday looks like the best day in the short-term forecast. Environment Canada is calling for a mix of sun and cloud, light winds, and a high of 5°C. Friday night turns clear, with the temperature dropping to -7°C.
The weekend starts well enough with sunny skies and 8°C on Saturday, but the pattern turns more unsettled again after that. Saturday night brings a 40 percent chance of rain showers or flurries, Sunday shifts to periods of rain with a high of 6°C, and Monday turns milder but wetter with cloudy skies and a 60 percent chance of rain and a high of 11°C.
Travel and Wardrobe Outlook
The bigger highway problems from Wednesday are easing, but Thursday morning is still a day for caution, especially with gusty winds and the lingering risk of a little freezing rain or flurry activity early on. With no active city alert in place, this is more of a nuisance-weather day than a major storm day, but exposed areas and untreated surfaces could still be slippery for a time.
A medium-weight winter jacket, gloves for the morning, and waterproof footwear are still a good idea today. By Friday afternoon, the weather should feel much more manageable, though the cold nights mean spring is not fully settled in yet. This clothing advice is an inference based on the official temperature, wind, and precipitation forecast.
Weather Trivia
Thunder Bay’s spring weather often works in fits and starts. Lake Superior and lingering cold air can keep the region bouncing between flurries, rain, sunshine, and sharp overnight freezes well into April. This week’s pattern — snow one day, gusty flurries the next, and a better Friday in between — is a textbook example. This is an inference based on the current multi-day forecast pattern.
Weather Overview
Thunder Bay weather update for April 9, 2026: no active alert, but flurries, gusty northwest winds, and an early freezing rain risk linger before a brighter Friday.
