Residents of Thunder Bay can expect cool and damp conditions to continue throughout the remainder of the week as temperatures remain slightly below seasonal norms. According to Environment Canada, the city is experiencing a stretch of cloudy weather with high humidity and fog, though conditions are forecast to improve significantly by early next week.
Recent data from the Thunder Bay Airport shows temperatures hovering between -1°C and 6°C over the past 24 hours. While there are currently no active weather alerts for the city, officials are advising caution for Thursday morning. As overnight temperatures drop to the freezing mark, there is a risk of freezing drizzle, which can create a thin, difficult-to-see layer of ice on roads, sidewalks, bridges, and parking lots.
Drivers and pedestrians are encouraged to remain aware of potentially slippery surfaces during the early morning hours on Thursday. While the immediate outlook involves damp and grey weather, relief is on the way. Forecasts indicate a warming trend, with temperatures expected to reach a sunny high of 13°C by Tuesday, April 21, 2026.
Additionally, the Lakehead Region Conservation Authority has issued a flood outlook for the broader area. This advisory remains in place due to recent rainfall, the ongoing spring thaw, and frozen ground conditions which can increase the risk of water runoff.
