March 12–14, 2026 Traveller’s Forecast

March 12, 2026

Kenora → Dryden → Ignace → Thunder Bay → Nipigon → Wawa → Sault Ste. Marie → Sudbury

Plus: Timmins → Sudbury

A fast-moving winter system will push west-to-east Thursday night into Friday, bringing snow, gusty winds, and pockets of blowing snow—especially along the Lake Superior shoreline and east toward Algoma/Sudbury. Plan for the best travel window Thursday daytime (before snow spreads in), with slower travel Friday, then improving conditions Saturday (still cold).

Key weather hazards by day

Thursday, March 12

West (Kenora–Dryden–Ignace):

Kenora: Mix of sun/cloud, SE wind gusting 40 km/h, high -3°C. Snow begins this evening with 2–4 cm expected overnight.
Dryden: Mainly sunny, high -4°C; snow tonight with low near -11°C.
Ignace: Sunny, high -4°C; periods of snow tonight, low near -12°C.

Thunder Bay–Nipigon:

Thunder Bay: Mainly sunny today, but snow begins late tonight. EC calls for 10–15 cm region-wide (heaviest toward the Ontario–Minnesota border) with E/SE gusts 50–60 km/h creating local blowing snow.
Nipigon: Daytime quieter (chance of flurries), with cloud increasing later; travel conditions trend worse overnight as the system arrives.

Wawa–Sault–Sudbury:

Wawa: Mix of sun/cloud, high -6°C (winds light most of the day).
Sault Ste. Marie: Mix of sun/cloud with a 30% chance of flurries, high near -4°C; winds increase overnight.
Sudbury: Mainly cloudy with 40% chance of flurries, high -5°C.

Timmins → Sudbury corridor:

Timmins: Mainly cloudy with 60% chance of flurries, high -8°C; cold night near -20°C.

Best bet Thursday: If you can, do the long haul in daylight Thursday and aim to be parked before late evening, especially west-to-east into Thunder Bay.

Friday, March 13

This is the most weather-impacted travel day.

Kenora/Dryden/Ignace: Snow continues (daytime snow noted for all three).
Thunder Bay: Snow through the day with about 5 cm in the city forecast, plus gusty winds (NE gusting 50 km/h) and reduced visibility at times.
Sault Ste. Marie: Snow + local blowing snow, about 5 cm, with strong easterlies gusting up to 70 km/h before winds turn north.
Sudbury: Snow and local blowing snow starts in the morning with 5–10 cm possible and E winds gusting 50 km/h.

Travel advice Friday: Expect whiteouts in bursts, especially in open stretches and along Superior/Algoma highlands. Build in major buffer time, and be ready to stop if visibility collapses.
