What to Wear (Wardrobe Coach)
Go full November kit: a thermal base layer, insulating mid-layer, and a wind-resistant jacket. Add a toque and insulated gloves—you’ll feel the difference at bus stops and on dog walks. Waterproof, grippy footwear helps on frosty sidewalks and any flurry bursts. Sunglasses are smart for bright snow glare.
Heads-Up for Travel
Early and late day, expect slick patches on bridges, ramps and side streets. Give extra stopping distance and clear all windows—scraping will be needed tonight and Sunday morning.
Lakehead Weather Trivia
Cold, dry nights under clear skies let heat escape fast—radiational cooling. That’s why Thunder Bay can plunge to double-digit wind chills overnight, even with calmer winds and sunshine due the next day.
