Wardrobe Recommendations
-

-
Tonight into Wednesday: Dress for steady snow and increasing wind—a wind-resistant outer layer, insulated gloves/mitts, warm hat, and a neck warmer will help a lot.
-
If travelling: Pack extra warm layers in the vehicle. Blowing snow can reduce visibility quickly, and delays are more likely during heavier snowfall.
-
Wednesday night: With temperatures dropping to -13°C, expect a colder feel after the snow, and watch for refreeze on roads and sidewalks.
Weather Trivia
Sault Ste. Marie can see rapid “weather flips” in March because temperatures often hover near 0°C. That’s the sweet spot where a storm can start as wet snow, then shift to drier, blowing snow as colder air wraps in behind the low—making visibility worse even after snowfall rates ease.

Special Weather Statement in effect as snow begins tonight and continues through Wednesday/Wednesday night, with 10–20 cm possible and local blowing snow.
