The cold air has prompted frost warnings across a large portion of the upper Midwest into central Ontario. Snow is even in the forecast for far northern Ontario and northwestern Quebec, close to Hudson Bay. The cold air may even produce some flurries across the highest elevations of southern Quebec and northern New England by Sunday morning.
