Residents of Milton should prepare for a chilly start to the week as Environment Canada forecasts a cold snap moving through the region. Following recent rainfall, temperatures are expected to drop significantly below seasonal averages through Wednesday.
The forecast includes a chance of flurries on Monday night, with temperatures reaching an overnight low of -5 degrees Celsius. Tuesday will bring a mix of sun and clouds with a chance of flurries and a daytime high of 1 degree Celsius. Tuesday night is expected to be the coldest period of the week, with clear skies and temperatures dipping to -6 degrees Celsius.
These temperatures are notably colder than Milton’s usual climate norms for early April, which typically see highs of 10 degrees Celsius and lows of 0 degrees Celsius. According to Environment Canada, residents should take precautions if spending time outdoors, as wind chill values between -10 and -27 present a moderate risk of frostbite and hypothermia without adequate protection.
Meteorologists indicate this unseasonably cool weather is part of a broader trend affecting Southern Ontario this spring. Influenced by lingering La Niña conditions and a split polar vortex that has funnelled Arctic air into the region, the spring season is experiencing more volatility than usual. This outlook matches long-range predictions from the Old Farmer’s Almanac, which had anticipated below-average temperatures and mixed precipitation for the month of April.
