Messy system to complicate travel in northern Ontario with ice moving in

Wintry weather is making a comeback in parts of northern Ontario as a new low-pressure system will kick off the final days in April with snow, freezing rain and ice.

Special weather statements are in place, urging residents and travellers to prepare for potential disruptions to commuting plans and power outages due to ice buildup.

Expect issues where freezing rain could slicken roads, bridges, and sidewalks. In areas that see straight snow or mixing, similar slippery conditions on surfaces are anticipated, so brace for slower commutes.

Icy conditions possible Sunday night into Monday

Another low-pressure system will cross the border late Sunday and into the day Monday. This new storm will have more cold air to work with as it pushes into northern Ontario.

Rain will begin Monday morning across northern Ontario, quickly changing over to mixed precipitation for communities north of Thunder Bay. The changeover will arrive for the Lake Superior shores through the afternoon.

We’ll see rain transition to snow farther north across portions of northwestern Ontario by Monday morning.

A period of freezing rain is possible between Timmins and Sudbury and areas northeast through Monday morning. Rising temperatures will force a changeover to rain here by the late afternoon hours.

Temperatures in the north and northwest will hover right around the freezing mark, making it difficult to know if precipitation will remain freezing rain or change back over to plain old rain.

Some areas could see up to 5 mm of ice accretion, while others that see snow could accumulate 5-15 cm.

Communities that see prolonged freezing rain or snow will have to contend with slippery roads, bridges, and sidewalks on Monday morning. Allow for extra time heading to work or school on Monday.

Conditions should improve as the storm exits the region Monday night and Tuesday morning.
