Thunder Bay

Spring snow storm hitting Thunder Bay Sunday evening

The heavy snowfall and blowing snow could cause reduced visibility. Snow will likely be heaviest on Monday and Tuesday, said Environment Canada. 

Environment Canada says Thunder Bay could get up to 45 centimetres of snow by Wednesday evening

A spring snow storm is expected to hit Thunder Bay Sunday evening. The city could get 25 to 45 centimetres of snow between Sunday and Wednesday evening, according to an Environment Canada snowfall warning released Sunday morning.

"Expect the heaviest snowfall amounts to be between Monday and Tuesday," said Danielle Feghali, a meteorologist at Environment Canada. "Tuesday evening, things should start tapering off."

Blowing snow could impact visibility as northeasterly winds will start picking up on Monday, she said. 

Environment Canada said road closures are possible and recommended postponing non-essential travel until after the storm. 

Feghali said the storm will be moving northeast toward Lake Superior and will continue north over northern Ontario. 

This storm was caused by a Colorado low, which is a low pressure system that forms in the rocky mountains. 

"It's going to extend kind of all the way toward James Bay, so it's going to be a pretty large system," said Feghali.

"What's unique about it is how slow the low (pressure) is moving," she said. "It's going to be extending over multiple days."
