Cold Now, but a Rollercoaster of Weather Incoming

Sudbury is waking up to clear skies and a frigid -13.1°C this Monday morning, with a wind chill making it feel like -19°C. The wind is coming from the north-northwest at 10 km/h, and the humidity is sitting at 85%. The barometric pressure is at 101.9 kPa and rising, indicating stable conditions—for now. Visibility is excellent at 24 km, so at least the cold comes with a bright, clear start to the day!

Monday: Sunny, But Don’t Let That Fool You

While the sun will dominate the skies today, the morning chill is no joke, with wind chills near -16°C. Winds will stay light, reaching up to 15 km/h, and the temperature will crawl up to a high of 1°C by the afternoon. The UV index is moderate at 3, so despite the cold, sunglasses might still be useful.

By evening, things start to shift—clouds will roll in early, bringing a 60% chance of flurries late tonight and overnight. Winds remain light at 15 km/h, and temperatures will drop to -5°C, with the wind chill making it feel like -9°C.

Tuesday: A Mixed Bag of Flurries, Rain, and a Warm-Up

Tuesday morning will be cloudy with a 40% chance of flurries, but as temperatures rise to 6°C, those snowflakes might turn into rain showers by the afternoon. The wind will pick up from the south at 30 km/h, making for a breezy and unpredictable day. The morning will still feel quite cold with a wind chill of -12°C, so don’t let the afternoon warmth fool you.

The night will remain cloudy, with temperatures staying above freezing at 1°C.

Midweek Brings More Cloud, Rain, and Then… Snowstorm?

Wednesday will be another cloudy day with a high of 6°C, but don’t get too comfortable—rain moves in by the evening, with temperatures hovering around 1°C overnight.

Thursday could bring a true taste of spring and winter, with rain or snow and strong winds making things messy. The high will struggle to reach 0°C. By nightfall, expect periods of snow, local blowing snow, and gusty winds. The temperature will plunge to -13°C, reminding Sudburians that winter isn’t ready to pack up just yet.

What to Wear?

For today, bundle up with layers, a warm coat, gloves, and a hat—especially for the chilly morning. By Tuesday afternoon, a lighter jacket might do, but keep rain gear handy. And by Thursday? Get ready for full-on winter conditions again.
