Bitter Cold and Flurries to Start the Day
Sudbury faces bitter cold with wind chills near -29°C tonight, but sunny skies midweek will give way to snow on Thursday. Stay bundled up to avoid frostbite!
Sudbury is waking up to a frosty -14°C this morning, with a light snowfall drifting through the city. The northwest wind at 21 km/h is adding an extra chill, making it feel like a numbing -23°C. The humidity sits at 68%, and the barometric pressure is rising at 102.0 kPa, indicating a gradual improvement in conditions. While there’s a 30% chance of flurries early in the day, skies will begin to clear by the afternoon. The wind, however, will pick up to 20 km/h, gusting to 40 km/h, keeping the wind chill at a stubborn -23°C throughout the day. The UV index remains low at 1—not that many are thinking about sunburn when their eyelashes are freezing!
Tonight: A Deep Freeze Sets In
Clear skies will dominate the evening, but with that comes a plummeting temperature. The northwest wind at 20 km/h will gradually ease, but it won’t do much to prevent the night from becoming brutally cold. The low is expected to hit -22°C, with wind chills making it feel closer to -29°C. With temperatures like this, frostbite can develop in minutes, so anyone heading out should be well-prepared with multiple layers, insulated gloves, and a warm hat.
Wednesday: Bright but Bitterly Cold
The midweek forecast brings mainly sunny skies, but don’t let the sunshine fool you—it’s going to be another frigid day. The morning will see a bone-chilling wind chill of -29°C, gradually “warming” to -15°C in the afternoon. A southwest wind at 20 km/h will kick in by morning, offering a bit of a change but not much relief. The daytime high will reach -8°C, making it one of the warmer days this week (if you can call that warm). Frostbite remains a risk, so Sudburians should stay bundled up.
By night, clouds will roll back in, bringing a 40% chance of snow and a slightly less extreme overnight low of -11°C.
Thursday: A Snowy Turn of Events
Thursday will bring a more active weather pattern, with periods of snow expected throughout the day. The high will climb to -4°C—practically tropical compared to the deep freeze earlier in the week. The snow will persist into the night, with temperatures dropping to -15°C. If you’ve been looking for an excuse to stay inside with a hot drink, this might just be it.
Sudbury’s Historic Weather for February 4
On this day in history, Sudbury has seen a wide range of temperatures. The warmest recorded high for February 4 was 6.3°C, while the record low bottomed out at a bone-chilling -36.1°C. So, while today’s cold is unpleasant, at least it’s not historic!
Wardrobe Wisdom: Dress for the Deep Freeze
With wind chills plunging into the -20s and even -30s, full winter gear is a must. A thick parka, insulated boots, thermal layers, and gloves are all essential to prevent frostbite. If you have to be outside for long periods, consider a face covering to protect against the biting cold. By Thursday, the snowier forecast means waterproof boots and outerwear will come in handy.
