While those in southern Ontario can look forward to a milder winter season, the more immanent forecast will look quite different.
What will start out as rain on Monday will begin to transition to a "thick, wet snow that will really come down with intensity" according to The Weather Network meteorologist Tyler Hamilton.
Hamilton goes on to say that areas at a higher terrain will start to see this change first, from Bancroft towards the Huron shores.
But on Monday evening, that rain and snow will head "right across the GTA to downtown Toronto and Hamilton" with "accumulating wet snow" into Tuesday morning, says Hamilton.
He goes on to say that some totals could see an excess of 30 cm with "blowing snow a concern [for] any regions near the shores of Lake Huron and Lake Ontario."
Just west of Barrie could see 30-40 cm of snowfall which is "almost 15-20% of Blue Mountain's total natural snowfall through the entire winter season."
London could also see a great deal of snow, getting up to 20 cm, while areas around Milton and Brampton possibly seeing up to 15 cm.
Downtown Toronto will fare better, however, only seeing about 5 cm of snowfall.
