Special weather statement in effect for:

  • Greater Sudbury and vicinity

Becoming wet and mild for Northeastern Ontario. A wintery mix of precipitation for areas north and west of Lake Superior.

An intensifying weather system currently over Kansas will track towards Lake Michigan tonight and cross Northeastern Ontario on Monday. This system will bring significant weather to much of Northern Ontario.

Northeastern Ontario: rain, at times rather heavy, will arrive tonight and continue for much of Monday. A general rainfall of 20 to 30 mm is expected before it changes to snow Monday night. The rainfall may have some impact on snow melt for any parts of Northeastern Ontario which have considerable snow pack. Some localized minor flooding is possible in some locales.

North and west of superior: periods of rain will spread across most regions adjacent to Lake Superior tonight except for regions closer to Lake Nipigon which should see primarily snow. The rain will likely transition to some freezing rain after midnight for the Lake Superior regions then change to snow Monday morning. A significant snowfall of around 10 centimetres is likely in most of the area from Lake Superior towards Nipigon. Freezing rain or snowfall warnings may be required. Travellers should give themselves extra time due to potentially icy roads tonight and accumulating snow and lower visibility on Monday.
