-
This morning: Dress for wind chill near -28—parka, warm mitts, toque, and a neck warmer/balaclava if you’ll be outside for more than a short time.
-
Today’s snow: Waterproof boots with good traction help—fresh snow can hide slick patches underneath.
-
Thursday: Sunshine helps, but mornings are still cold—layers are best so you can adjust as it warms a bit in the afternoon.
-
Thursday night into Friday: Keep winter gear handy again with snow returning and temperatures staying below freezing.
Weather Trivia
A small snowfall (2–4 cm) can still create big travel issues when temperatures are cold. Snow tends to stay dry and “powdery,” and even light winds can drift it across open stretches—especially along highways and cutlines.
