Accumulating snow , gusty winds, and chilly air will make this second week of April feel more like a January afternoon for a wide swath of Ontario. DON’T MISS: Canada’s weather map looks broken: Arctic heat meets southern chill Temperatures falling 10-15 degrees below seasonal will allow snow to build across parts of the province on Monday. Cold, gusty winds blowing behind that system will give rise to bands of lake-effect snow into Tuesday, as well.
In parts of northern Ontario, snowfall warnings are in effect for as much as 25 cm expected to fall. Be sure to monitor local weather alerts and check highway conditions before heading out to start the week. Heavy snow piles up across northeastern Ontario Monday A developing low-pressure system moving across the Great Lakes will slide across Ontario to start the week, bringing accumulating snow to the northeast and portions of cottage country.
Heavy bursts of snow are in the forecast across Georgian Bay and northeastern Ontario, pushing east toward the Ottawa region by Monday night. Sudbury is the place to be this week if you’re pining for a healthy dollop of snow. The region is on track to see 15-25 cm of snow through Tuesday.
Peak snowfall rates of 3 to 5 cm per hour are possible across the area at times, bringing reduced visibility and periods of blowing snow. Strong winds whip through on Tuesday We’ll see snow continue across eastern Ontario by Tuesday morning as the second round of snow builds over the lakes. Strong northwesterly winds along the shores of Lake Huron and Georgian Bay could reach 60-80 km/h at times, while Prince Edward County could see westerly winds of 60-80 km/h as the system departs the region.
Folks across the Greater Toronto Area will escape the strongest winds, but widespread gusts of 40-60 km/h are possible, with an occasional gust as strong as 70 km/h. Temperatures will plunge 10-15 degrees below seasonal across southern and eastern Ontario during the day Tuesday. We’re likely to see wind chill values in the minus double digits with the combination of cold air and gusty winds.
Very cold air aloft—so cold, in fact, that it’s reminiscent of the winter months—will help trigger lake-effect snow off of Lake Huron and Georgian Bay through Monday evening into Tuesday. Stay aware of rapidly changing conditions if you’re planning to travel across the snowbelt regions while these bands of snow are active.
