A few eastern flurries linger Thursday, but Kenora, Dryden and Fort Frances lead a broad turn toward sunshine through Saturday

THUNDER BAY, Ont. — Nov. 12, 2026 – Weather – High pressure is building into Northwestern Ontario, clearing the west first while clouds and flurries linger around Lake Nipigon and Greenstone. The main travel concern is patchy early flurries and refreezing on untreated surfaces, followed by cold Friday-morning wind chills.

No active warning banner appeared on the Environment and Climate Change Canada pages checked for Kenora, Red Lake, Dryden, Fort Frances, Sioux Lookout, Nipigon, Greenstone, Armstrong or Ignace at issue time.

Thursday: West turns sunny, eastern districts keep cloud

Fort Frances is mainly sunny at 1 C, followed by a low near -9. Ignace clears after an early 30 per cent chance of flurries, reaches -1 and drops to -10 with a wind chill near -15 overnight.

Red Lake and Sioux Lookout remain cooler and cloudier early, with highs near -1 to 0 before clearer skies tonight. Sioux Lookout falls near -8 to -9, while Red Lake drops into the upper minus single digits.

Overnight lows across Nipigon, Greenstone and Armstrong are generally near -5, locally colder around Armstrong.

Friday: Sunshine dominates the west

Kenora reaches 1 C in sunshine; Dryden, Fort Frances, Red Lake, Sioux Lookout and Ignace are mainly sunny with highs close to -1 to 1 C. Clear Friday-night lows range from about -8 to -13, with the coldest pocket around Fort Frances.

Farther east, Nipigon, Greenstone and Armstrong hold on to more cloud and a 30 per cent chance of flurries in places. Highs sit near -1 to 0, with lows near -4 to -6.

Saturday: Bright and milder

Sunshine becomes widespread. Kenora and Dryden reach about 4 C; Fort Frances, Red Lake, Sioux Lookout and Ignace reach 2 to 4 C. Nipigon, Greenstone and Armstrong are cooler at roughly 1 to 2 C but trend sunnier. Saturday-night lows range from about -5 to -8.

Wardrobe guidance

Dress for the morning wind chill rather than the afternoon high: a warm mid-layer, insulated jacket, toque and gloves are appropriate. Use footwear with traction where early flurries or refrozen moisture leave slick sidewalks and secondary roads. Sunglasses will be useful as sunshine reflects from patchy snow.

Weather trivia

Clear nights often cool faster than cloudy nights because the ground can radiate heat more efficiently to space. That helps explain why several sunny Friday forecasts are followed by overnight lows near or below -10 C.
