6099

Thunder Bay – Weather – Current (6:00 a.m. EST, Fri Nov 14): It’s mostly cloudy and –2.8°C at the airport (feels like –4). Pressure 101.6 kPa (falling), humidity 88%, wind WNW 3 km/h, visibility 24 km

Today — Bright breaks, breezier and milder

A mix of sun and cloud with winds becoming southeast 20 km/h, gusting to 40 this morning. After a wind chill near –9 early, we climb to a high of 7°C (UV 1 – low). It’ll feel like a small November bonus, but the breeze will add some bite on open stretches.

Tonight — Clouds thicken, rain risk late

Mainly cloudy with a 60% chance of rain overnight. Winds SE 20 km/h gusting to 40 then becoming light early this evening. Low +2°C. Most roads stay wet, but watch cooler side streets toward dawn.

Saturday — Two seasons in one day

A mix of sun and cloud with a 60% chance of rain in the morning changing to a 30% chance of flurries in the afternoon as colder air sweeps in. Winds flip NW 30 km/h, gusting to 60—it’ll turn raw despite a high near 6°C earlier.
Saturday night: Cloudy, low –2°C—wet surfaces can refreeze late.

Sunday — Calmer and decent

A mix of sun and cloud, lighter winds, and a high near +5°C. Sunday night: Cloudy periods, low –4°C.

Monday — Seasonable

Another mix of sun and cloud, high +1°C. Monday night: Cloudy periods, low –4°C.

What to wear

Start with a long-sleeve base, add a light fleece, and a wind-resistant jacket for today’s southeast gusts. Keep a compact rain shell handy for tonight and Saturday morning, and switch to hat and gloves for Saturday afternoon once the northwest wind bites.

Travel notes

  • Today/Tonight: Crosswinds on exposed roads as winds turn SE; evening rain makes for slick leaves and puddles.

  • Saturday: Expect gusty NW crosswinds and a rain-to-flurry transition—traction can change fast.

  • Late Sat night: Watch for black ice as temperatures dip below freezing.
