Weekend rain expected for the city, North Shore

THUNDER BAY - Residents in Thunder Bay and along the North Shore should be prepared for unsettled weather heading into the weekend. 

Environment Canada meteorologist Steve Flisfeder said the forecast shows periods of spotty rain, potential thunderstorms, possible hail, and a gradual cool-down by early next week.

“Friday, there will be some shower activity through most of the afternoon,” said Flisfeder. “Thunderstorms will develop through the day, reaching the North Shore later in the afternoon.”

Thunder Bay can expect showers and isolated thunderstorms by early afternoon, as the system pushes east toward the North Shore. Heavy downpours are likely, with Flisfeder noting that “torrential rain is looking pretty likely,” especially through Friday afternoon and evening.

Small hail is also possible in Thunder Bay, though that threat lessens as the storm moves further east.

Temperatures in Thunder Bay and inland from the North Shore will climb into the mid to high 20s.

“For Saturday, that low-pressure system is still going to be kind of lingering through the Northeast,” Flisfeder said, adding that Thunder Bay will see spotty showers.

“It’s not going to be quite as impactful or significant as Friday, but you will still need an umbrella just in case.”

Temperatures will dip slightly, with Thunder Bay and inland areas reaching the low 20s. Shoreline communities along Lake Superior will stay cooler, likely in the high teens.

By Sunday, the weather is expected to improve.

“It’s looking like it should be pretty clear throughout the entire day,” Flisfeder said.

A few spotty showers are possible late Sunday night into Monday, but they're not expected to be significant.

Temperatures will rebound across much of the region, returning to the mid to high 20s. As usual, lakeshore areas will remain cooler, likely in the high teens to low 20s.

Beyond the wekeend, inland temperatures on Monday will hold steady in the mid-20s around “24 to 26 C kind of range.” However, a cooling trend begins Tuesday and continues through Wednesday and Thursday.

“Once we get to Tuesday, that’s when you do start to get into a bit of a cooler stretch,” said Flisfeder, noting that those closer to the lake will feel the drop more noticeably.
