Thunder Bay, Ont., and surrounding areas welcomed its first true dump of snow in 2025 over the weekend.

Environment Canada estimates 12 to 15 centimetres of snow fell between Sunday morning and Monday.

Areas east of Thunder Bay likely received more snow than the city, according to radar estimates. However, the agency could not provide a specific snowfall amount for the north shore.

"So we have an Alberta Clipper moving through the area and it's bringing along with it some snow, at times heavy," said Lucas Alexopoulos, an operational meteorologist with Environment Canada.

"There is some lake enhancement with this Alberta Clipper, which is what is producing those heavier snowfall totals locally. The heaviest snow looks to be east of the Thunder Bay city proper, maybe more toward Nipigon, on the shore of Lake Superior," he added.

Weather alerts in the northwest have ended as of Monday morning, however Environment Canada warns that road conditions may still be hazardous in some areas.

"Some gusty northerly winds could develop which could [cause] local blowing snow as well," said Alexopoulos.

The snow did impact some school transportation in the region, with routes cancelled for the Superior-Greenstone District School Board.

In Thunder Bay, student transportation is expected to run through the day, however Student Transportation Services of Thunder Bay said some rural routes may experience delays due to road conditions.

Road clearing expected to be complete by mid week

In a media release issued Monday morning, the City of Thunder Bay said all priority routes had been cleared, and residential street plowing is expected to be complete by Wednesday.

"Plowing on arterial, collector, and core area street sidewalks started at 3:00 a.m. and should be completed shortly. Residential sidewalk and trail plowing will begin once priority routes are done, with an estimated completion by Thursday," reads the media release from the City of Thunder Bay.

Sanding and salting equipment is expected on city roads and sidewalks through the week, according to the City of Thunder Bay.
