|Very cold air will surge into southern Quebec next weekend. Snow flurries are likely, even in Montreal. (AccuWeather)|
As we look ahead to the upcoming weekend, a strong cold front will usher in the lowest temperatures of the season so far. Overnight lows will drop well below freezing in eastern Ontario and southern Quebec, as cold as -6C (21F) by Sunday morning. In addition to the cold, snow flurries are possible, and even some accumulating lake effect snow closer to the Great Lakes. The forecast will need some fine-tuning as we get closer, but expect the coldest weekend of the season so far.
