A light dusting of snow set for much of Southern Ontario starting Sunday night is forecast to be followed by another cold snap.
Environment Canada says the region should see two to four centimetres of snow, though areas northeast of Lake Huron and Georgian Bay may get up to 10 cm.
But that taste of winter is expected to be accompanied by strong winds of up to 70 kilometres an hour along the Great Lakes.
They could gust up to 90 km/h on the northeast shore of Lake Erie and Picton-Sandbanks Park.
Forecasters say wind combined with blowing snow could drop visibility down to 200 metres or less at times.
And it says the snow should be followed by an Arctic cold front resulting in wind chills ranging from -25 to -35 by Tuesday morning.
Flurries and snow squalls are forecast for Monday in the snow belt southeast of Lake Huron and Georgian Bay.
