Snow wraps up early today, but more light snow returns tonight, and then Friday flips colder in a hurry with temperatures falling through the afternoon.
Roads crews will be out, however as of 7:00 am in the Waterfront District roads and sidewalks are very slippery.

Wardrobe Recommendations
-
This morning (freezing drizzle): waterproof outer layer + boots with strong tread (or ice grips). If you’re walking, take it slow—this is “surprise ice” weather.
-
Tonight (light snow): add a warm mid-layer and keep gloves/mitts dry—wet snow + wind makes the cold feel sharper.
-
Friday night’s -26°C: upgrade to full winter gear—parka, insulated boots, warm base layer, and face coverage if you’ll be out for more than a few minutes.
