Winter Weather Update

A Snowy Morning in Greater Sudbury

The winter wonderland continues in the Greater Sudbury region this morning, with light snow falling as of 7:00 AM EST. Temperatures sit at a chilly -10.3°C, and a west wind blowing at 13 km/h is making it feel more like -17. Humidity is at 85%, adding an extra crispness to the air, and the barometric pressure is rising at 101.2 kPa, signaling some clearing later today. Visibility is reduced to 4 kilometers due to the ongoing snowfall, so drivers should exercise caution during the morning commute.


Tuesday’s Forecast: Snow Tapers Off, Cloudy Skies Persist

Periods of light snow are expected to end this afternoon, leaving behind mainly cloudy skies with a 40% chance of flurries lingering into the evening. Snowfall accumulations will amount to about 2 cm, enough to keep things slippery. Winds will shift to the north this morning, increasing to 20 km/h, and temperatures will climb to a high of -7°C. However, the wind chill will make it feel like -16 for most of the day, so don’t let the thermometer fool you—it’s still a cold one out there.


Tonight: Frosty Conditions Settle In

As the sun sets, the clouds will remain, bringing a continued 40% chance of flurries. Winds from the northwest at 20 km/h will ease in the evening, but the temperature will drop significantly to a low of -18°C. With the wind chill, it will feel more like -21 overnight, making frostbite a concern for anyone outdoors for an extended period.


Midweek Outlook: A Snowy Trend

Wednesday will stay mainly cloudy, with light winds of up to 15 km/h and a high of -9°C. Wind chills will be biting early in the day, starting at -22 in the morning and moderating to -14 in the afternoon.

Snow returns Wednesday night, with periods of light accumulation and a low of -9°C.

Thursday brings continued snow, with temperatures rising to a high of -4°C, making it one of the milder days of the week. Thursday night will feature cloudy periods and a 40% chance of flurries, with a low of -10°C.

Friday will bring yet more snowfall, with a high of -2°C. By Friday night, snow will persist, and the low will dip to -8°C, keeping the wintry trend alive into the weekend.


What to Wear

Today’s snowy and cold weather calls for full winter armor. Layer up with thermal underlayers, a warm fleece or sweater, and a windproof parka. Insulated gloves, a toque, and a scarf are essential, along with waterproof boots to navigate the slippery snow accumulation. Frostbite risks are present, so make sure all exposed skin is covered when braving the outdoors.


Weather Trivia: Sudbury’s Snowy Legacy

Did you know that Sudbury has an average annual snowfall of about 274 cm? That’s more than enough to fill a hockey rink with snow every year! With its proximity to Lake Huron and its elevation, Sudbury is no stranger to heavy snowfalls, making today’s 2 cm look like a flurry in comparison.


In a nutshell

Greater Sudbury sees light snow tapering to flurries this afternoon, with wind chills near -16°C. More snow expected Wednesday night and into the rest of the week.
