The main weather highlights over the next five days will be mainly across the United States with the Rockies storm and Karen, leaving Canada with some frontal passages and not much else.
--The storm that will bring significant snow to Wyoming and parts of South Dakota over the next 36 hours will track up toward Lake Superior this weekend, but I do not expect to see any measurable snow over northwestern Ontario with this as the storm will be weakening and the low-level temperatures will not be cold enough.
--However, this same storm will still be capable of producing some heavier thunderstorms over southern Ontario on Sunday with potential downpours into Quebec later Sunday night and Monday. Keep in mind, the main severe weather threat with this front will be over the Midwest U.S. Friday and Saturday.
--Tropical Storm Karen will get drawn northward into the Gulf Coast later this weekend then ride northeast and weaken along that same cold front early next week. The remnants of Karen could enhance rainfall along the front in the Nova Scotia/PEI region around Tuesday next week.
--There will be a quick shot of chilly air during the Monday to Tuesday period from Manitoba to Ontario and Quebec, but temperatures will quickly warm up again by Wednesday.
--Models are at odds on whether or not there will be an early snow event over Alberta and Saskatchewan around Oct. 11 or 12. I will keep you posted on this.
--Overall, temperatures between now and Oct. 15 will average above-normal across eastern and Atlantic Canada.
--After Oct. 15, there are indications of a pattern change, which could bring much cooler air into eastern Canada, while British Columbia turns warmer and drier.
Currently working on the winter forecast for Canada. First indications are that this winter could be very changeable from month to month across the country.
FYI, the AccuWeather winter forecast for Canada will be released to the public on Oct. 16.

Plenty of cold to talk about and a wintry mess late in the weekend and early next week in the East.
Here are the latest unofficial storm snowfall reports out of British Columbia and Alberta
The combination of snow, strong winds and very low temperatures is making for some tough travel across southwestern Canada.
