Highs near 10 C arrive Saturday in the west, while Nipigon, Greenstone and Armstrong face a windier, wetter Sunday

Sun first, showers later

THUNDER BAY, Ont. — Issued Friday, Nov. 6, 2026, at 6:11 a.m. EST – WEATHER –A ridge of high pressure will give Northwestern Ontario a dry, bright Friday and Saturday before cloud and scattered showers arrive in the eastern part of the region Sunday. Environment and Climate Change Canada issued the short-range and extended bulletins at 5:30 a.m. EST Friday.

Cold morning wind chills and the Sunday return of showers are the main practical concerns.  It is a morning for walkers to grab a pair of gloves. Motorists heading out might be scrapping the first frost off the windshields.

Nipigon also has a 60 per cent chance of showers, will be windy and reaches 7 C. Wet roads and gusts may make travel less comfortable along Highway 11 and Highway 17, though Environment Canada did not specify rainfall totals in the morning bulletin.

Wardrobe and travel

Travellers heading through Armstrong, Greenstone or Nipigon on Sunday should add waterproof footwear and a rain shell and allow for wet pavement.

Weather trivia

A ridge is an elongated area of relatively high atmospheric pressure. It often brings sinking air and fewer clouds, which fits the sunnier first half of this forecast before the next system approaches.
