Get ready for more Arctic air and numbing wind chills.

Environment Canada has issued a cold weather alert for the region.

A cold front is sweeping across southern Ontario today and tonight.

It will sweep south across southern Ontario reaching southern Georgian Bay to just south of Algonquin Park by early this evening and the 401 corridor overnight. The front is expected to bring two to four centimetres of snowfall to the region however areas northeast of Lake Huron and Georgian Bay could see local snowfall amounts up to 10 centimetres.

Strong and gusty southwesterly winds are expected to develop ahead of the front. As snow associated with the front moves in, local blowing snow reducing visibility to 200 metres or less at times will be possible especially over exposed areas. The strongest winds are likely near the shores of the Great Lakes where gusts between 50 and 70 kilometres per hour are possible.
