Sunshine rules today through Wednesday, but the mornings bite
THUNDER BAY – At 8:00 a.m. EST, it’s a clear and cold start at –6.6°C (call it –7°C) at the airport. The pressure is 101.9 kPa and rising, humidity 70%, with a light west wind near 12 km/h and 32 km visibility. It feels like –12 with the breeze, but blue sky is the theme.
Today – Sunny and seasonably cold
Sunshine holds from start to finish with winds up to 15 km/h. The afternoon reaches +1°C, though the wind chill near –13 this morning will linger in shaded spots. The UV index is 1 (low). It’s a day where the sun looks warm and the air reminds you it’s November.
Tonight – Clear and sharply colder
Skies remain clear with only a light breeze. The temperature dips to –12°C. Expect a wind chill near –6 in the evening, falling to about –15 overnight. Any damp patches will refreeze, so watch bridges and side streets early.
Tuesday – Bright copy-and-paste of today, a tick cooler
Another sunny day with winds up to 15 km/h and a high near 0°C. The morning wind chill near –18 will get your attention before the sun softens the edge. Tuesday night stays clear with a low near –10°C.
Wednesday – Still sunny, slightly milder, clouds return at night
The midweek “warm-up” nudges the high to +3°C under sunny skies. Wednesday night brings increasing cloudiness with a low near –3°C as the next weak system approaches.
What to wear & getting around
Dress in layers: a thermal base, a warm mid-layer, and a wind-resistant jacket. Add a toque and insulated gloves for the morning commute; you may peel a layer by mid-afternoon. Choose grippy, waterproof footwear for frosty sidewalks and any evening refreeze. Drivers should plan for black ice late tonight and early mornings, and a few light crosswinds on open stretches.
Lakehead weather trivia
On cold, dry days like these, radiational cooling does the heavy lifting at night—clear skies let heat escape, so dawn often feels much colder than midnight.
