Warmer-than-normal temperatures in Ontario are expected to dominate the heart of the fall season, with extended periods of fair weather and warmer-than-normal temperatures during the second half of September and October, said The Weather Network in its fall forecast.
However, a pattern change during late fall should bring an earlier arrival to winter weather, and more winter weather leading up to the holidays than we have often seen over the past 20 years.
This period of colder weather should also bring an abundance of lake effect snow to the traditional snowbelts east and southeast of the Great Lakes.
“We have become accustomed to very mild Decembers, but this year should bring more typical amounts of winter weather during the weeks leading up to and through the holidays,” said The Weather Network in its forecast.
Nationally, while most of Canada has seen an early arrival of cooler early fall weather, warm weather is not finished with much of Canada just yet. Late September and October will feature extended periods of pleasant fall weather with near seasonal or above seasonal temperatures.
Most of Canada should see near normal or above normal temperatures, with the warmest weather relative to normal extending from Ontario to Newfoundland.
Across most of Canada, the forecast calls for near normal precipitation totals for the fall season. However, for most of B.C., the forecast calls for above normal precipitation. Most of Atlantic Canada could also end up wetter than normal as the tropical season continues to be very active.
