Thunder Bay – Weather Desk – The Dryden–Vermilion Bay corridor is starting Monday under a blanket of cloud and cold air, but the bigger story arrives tonight: snow moves in this evening (2–4 cm) with a risk of freezing drizzle overnight, and west winds gusting to 50 km/h may create areas of drifting and reduced visibility. If you’re travelling Highway 17 later today or Tuesday morning, plan for winter driving conditions.

Today’s Weather Overview

A light ENE wind at 11 km/h is enough to make it feel colder, with a wind chill of -22. Pressure sits at 102.3 kPa, and visibility is 16 km.

Today (Monday, Dec. 22)

Tonight

• Tonight into Tuesday: Add water-resistant outer layers and make sure boots have solid tread—snow plus freezing drizzle can mean slippery footing and slick roads.

• Windy overnight: A snug hood or windproof hat helps when gusts ramp up—cold air sneaks in fast around ears and neck.
