By Sunday morning, the lake effect snow machine will be on thanks to steady northwesterly winds over relatively warm lake waters. Isolated showers and wet thunderstorms will begin late Saturday afternoon for parts of southern Ontario. Temperatures will drop steadily overnight, allowing most areas to transition into storms. Sunday morning, lake effect zones will become more pronounced over Lake Huron and Georgian Bay as winds align, allowing for steady snowfall for communities southeast of the lake shores. The heaviest snow in these areas is expected to fall early Sunday morning through the afternoon. The hardest hit areas could see locally 10-20+ inches of snow. Conditions will change quickly over short distances under the snow, possibly catching drivers by surprise when visibility drops to near zero in places. It never hurts to take it slow and consider changing non-essential plans in areas expecting heavy snow this weekend. Snow will reduce visibility even in areas where no snow is falling at the time. Some of the rocks could become strong enough to see disturbances push into parts of the Greater Toronto Area and the 400 freeways. While no accumulations are expected here because the ground is still warm, it will be a reminder that winter is indeed on his way.
The cold continues, more snow next week
Widespread cooler-than-seasonal conditions are expected to prevail next week and beyond, with another strengthening picture of arctic air and temperatures more typical of early December at times. This will bring additional lake effect snow to the traditional snow belt areas east and southeast of the Great Lakes starting Wednesday, with more precipitation continuing into next weekend. Local snow totals will be rather impressive. DON’T MISS: Freezing weather is inevitable. Here’s what you need to prepare A chance for the first widespread snow cover of the season Tuesday night and Wednesday for eastern Ontario, and possibly parts of the south.
