Special weather statement in effect for:

      • City of Thunder Bay

Becoming wet and mild for Northeastern Ontario – a wintery mix for northwest of superior.

A rapidly intensifying disturbance brewing in Kansas is setting its sights on Ontario. It will track towards Lake Michigan tonight and cross Northeastern Ontario on Monday.

Northeastern Ontario: some patchy freezing drizzle is affecting parts of the region this morning especially in Chapleau and Kapuskasing. Roads and sidewalks may be rather slippery until temperatures moderate during the day. Some roads have been reported to be rather slippery with some fog in and around St Joseph Island early this morning.

Rain, at times rather heavy, will arrive later this afternoon for the whole area and continue tonight and 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.

Northwest of superior: periods of rain will settle in 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 a little later tonight 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.

Travellers should give themselves extra time due to potentially icy roads tonight and accumulating snow and lower visibility on Monday.
