Residents in Thunder Bay are waking up to a frigid start on Tuesday, April 7, 2026, as temperatures reached -17 C with a wind chill of -20 C early this morning. While the city has faced significant snowfall recently, Environment Canada reports that there are currently no active weather alerts in effect for the area.
Clear skies throughout the day will allow temperatures to rise to 1 C by this afternoon. However, the mild weather will be short-lived, as snow is expected to return overnight. Residents can expect roughly 2 cm of accumulation Tuesday night, followed by an additional 2 to 4 cm of snow throughout the day on Wednesday, April 8.
A steady warming trend is set to follow the midweek snow. Temperatures are forecast to reach 5 C on Thursday, 6 C on Friday, and 8 C by Saturday, April 11. These temperatures are expected to reach the seasonal normal for early April in Northwestern Ontario.
This recent weather continues a pattern of heavy precipitation for the region. March 2026 recorded approximately 43 cm of snowfall, significantly higher than the typical long-term average of 27 cm for the month. This follows a period earlier in April when the city was impacted by heavy snowfall, which brought significant accumulations to the area.
