Thunder Bay – WEATHER DESK – Thunder Bay is starting Friday in misty, damp air, with a falling barometer signalling an active pattern.
The big story today is a messy mix: freezing drizzle risk this morning and early afternoon, followed by rain later today, then a switch to snow overnight. That changeover can make roads go from wet to slick quickly—especially late tonight and early Saturday.

Wardrobe Recommendations
-
This morning: Dress for -8°C and misty air—a warm coat, hat, and gloves are still needed. The dampness makes the cold feel sharper.
-
Freezing drizzle risk: Choose boots with good traction. Sidewalks and parking lots can glaze over quickly even if drizzle is light.
-
This afternoon: With rain and temps near +2°C, a water-resistant outer layer helps (and keep a dry layer in your bag/car if you’ll be out long).
-
Tonight into Saturday morning: Plan for the wet-to-snow switch and possible refreeze. If you’re driving late, slow down and watch for slick patches on bridges and untreated roads.
Weather Trivia
Freezing drizzle is sneaky because it often falls lightly, but the droplets are supercooled and can freeze the instant they hit pavement. That thin glaze can be harder to see than fresh snow—one reason it causes so many slips and minor collisions.
