A depression in Montana brings a wide band of winter precipitation to parts of Ontario and Quebec. Many areas in both provinces could receive 15 to 30 cm of snow through Monday. Winter storm, freezing rain, snowfall and warnings, as well as special weather reports, are in effect.

After the snowfall that started in Ontario and Quebec on Sunday afternoon, there will be freezing rain across the region as a warm front begins to lift over southwestern Ontario. Slightly higher terrain areas, such as Kitchener-Waterloo, can experience several hours of ice storm and difficult travel conditions are expected.

The precipitation will start as snow in eastern Ontario and southern Quebec before changing to freezing rain early Monday morning and then to rain in the afternoon. Total snowfall in cottage country could vary between 10 and 20cm before the precipitation turns to rain on Monday morning.

“Consider postponing non-essential travel until conditions improve. The rapid accumulation of snow could make it difficult to travel in some places. Surfaces such as highways, roads, driveways and parking lots can become icy and slippery, ”says Environment Canada and Climate Change (ECCC) in the winter storm warning for Parry Sound – Muskoka.

Precipitation totals will not be extreme, but 10-25mm for these areas will create slippery driving conditions and help melt snow that touches the ground. The rain will continue until early afternoon over southern and eastern Ontario, persisting in the evening over western Quebec.


Strong wind gusts will persist through Monday throughout the day, strengthening further in the evening as the cold front moves and the gusts return to southern Ontario behind the system. Gusts of 50 to 70 km / h are expected as the cold air descends towards the south, which will lead to a blustery start to the week.
