Wax up the snow shovel and fuel that snowblower for Monday – Old Man Winter might be aging as the calendar clicks along, but he is hanging on.

Sunday’s Forecast: Clearing Up, but Windy and Warmer
Periods of snow will continue this morning before clearing out, leaving behind 2 cm of fresh accumulation. However, the wind will quickly shift to the northwest, picking up to 30 km/h with gusts up to 50 km/h—so expect some blowing snow and a bit of a blustery day. Temperatures will rise to +4°C, a nice change from the deep freeze we’ve been used to, but the wind chill will make it feel like -10°C this morning before things warm up.
The UV index is low at 2, so no need to worry too much about sun exposure today.
Tonight, expect partly cloudy skies, but clouds will roll in around midnight, bringing periods of light snow overnight. Winds will start strong from the northwest at 20 km/h, gusting to 40 km/h, but they’ll die down later in the evening. The low will drop to -6°C, with a wind chill making it feel like -8°C.
Looking Ahead: Snowstorm on Monday, Then a Deep Freeze
Monday brings a significant snowfall event, with 10 to 15 cm expected throughout the day. If you have travel plans, be prepared for reduced visibility and slippery roads. The wind will shift again, coming from the north at 20 km/h late in the afternoon, and temperatures will hover around 0°C. However, don’t let that fool you—wind chills will make it feel like -5°C in the morning and -11°C by the afternoon as colder air pushes back in.
Monday night, the snow continues as temperatures drop to -11°C.
Tuesday will be noticeably colder, with a mix of sun and clouds and a high of only -10°C. The night stays cloudy, with a further drop to -13°C.
Wednesday looks mostly cloudy with a 40% chance of flurries and a slightly warmer high of -1°C. The night remains cloudy with periods of clear sky and a low of -9°C.
What to Wear?
Today’s weather calls for layers—you’ll need a warm jacket this morning, but by the afternoon, lighter outerwear might be enough. Don’t forget gloves and a hat, especially with those gusty winds. Monday’s snowstorm will make waterproof, insulated boots a must, and as temperatures drop midweek, full winter gear will be needed once again.
