Special weather statement in effect for:

  • Greater Sudbury and vicinity

A wintery mix of precipitation for much of Northern Ontario.

A deepening low pressure system from the Southern States will reach Lake Michigan overnight then track across Northeastern Ontario on Monday. This system will bring significant weather to much of Northern Ontario.

Northeastern Ontario: temperatures will remain mild tonight through Monday. Patchy drizzle and fog will give way to rain, at times rather heavy, later tonight, and a general rainfall of 20 to 30 mm is expected by Monday night. The rain is then forecast to change to snow Monday evening, as temperatures drop below zero. Most areas will receive around 5 cm or so of snowfall on Monday night, and gusty northerly winds will result in some blowing snow as well.

Near the northern and Western Lake Superior shore: patchy drizzle and fog will change to periods of rain tonight. The rain will likely change over to freezing rain or ice pellets overnight then change to snow Monday morning. Freezing rain warnings are in effect for these regions. Snowfall up to around 10 cm is possible by Monday night.

Around Lake Nipigon: snow will begin tonight, with a risk of freezing rain or ice pellets overnight. The snow will continue Monday, then taper off late in the day. Total snowfall amounts in the 10 to 15 cm range are possible.

Travellers should give themselves extra time due to potentially slippery roads due to freezing rain or accumulating snow. Low visibilities may also occur in snow and blowing snow.

Please refer to your public forecast for further details.

The public is advised to monitor future forecasts and warnings as warnings may be required or extended.
