According to the latest forecast from Environment Canada, the day will begin with mainly sunny skies. However, this pleasant start will be short-lived as increasing cloudiness is expected to move in around noon.
Afternoon Snow and Evening Chill
The forecast calls for light snow to begin late in the afternoon. This snowfall is expected to continue into the evening before tapering off and ending near midnight. Following the snow, skies will become mainly cloudy overnight.
During the day, the temperature will hold steady near minus 10 degrees Celsius. The wind will make it feel significantly colder, with a wind chill value near minus 15. The UV index for the day is rated at 1, which is considered low.
Overnight Low and Accumulation
The mercury will drop overnight to a low of minus 14 degrees Celsius. Environment Canada predicts about 2 centimetres of snow accumulation from this system. Winds are expected to be around 15 km/h, contributing to harsh wind chills.
Wind chills will plummet to minus 15 in the evening and a biting minus 22 overnight, creating potentially dangerous conditions for anyone spending extended time outdoors without proper protection.
