Greater Sudbury wakes up to a frosty -12°C this Monday morning under cloudy skies. A light south wind at 14 km/h adds an extra bite, making it feel like -19°C with the wind chill. The humidity sits at 81%, and the barometric pressure is at 102.0 kPa but falling, hinting at some unsettled weather ahead. Visibility is excellent at 32 km, so no issues on the roads—just a need for some extra layers to fight off the cold.

Throughout the day, expect mostly cloudy skies with a 30% chance of flurries in the morning. The wind will pick up, shifting to the south at 20 km/h and gusting up to 40 km/h, helping to bring in slightly milder air. The high will climb to -2°C, a welcome improvement from this morning’s deep chill. However, the wind chill will still make it feel like -19°C in the morning and around -8°C in the afternoon. The UV index is low at 2, so sun protection isn’t a major concern today.

Tonight: Partly Cloudy with a Milder Low

As the evening progresses, the skies will clear slightly, leaving partly cloudy conditions. The wind will calm down, becoming light early in the evening. The temperature will drop to -4°C, with a wind chill hovering near -9°C. Not too bad for early March in Northern Ontario!

Tuesday: A Mix of Snow, Rain, and Freezing Drizzle

Tuesday brings a bit of a weather rollercoaster. Snow is expected in the morning, accumulating about 2 cm before it changes to a mix of rain showers and flurries around noon. There is also a risk of freezing drizzle in the morning, so be cautious if you’re out on the roads. The wind will stay light at up to 15 km/h, and the high will reach +1°C. The morning will still feel chilly with a wind chill of -8°C, so winter gear is still a must.

By nighttime, periods of snow return, with temperatures dipping slightly to -1°C.

Midweek Outlook: More Rain and Snow
