This is my preliminary forecast for the winter 2010/2011.
It appears that the coldest part of the winter relative to normal from the Prairies through most of eastern Canada will be the first half. The second half is looking progressively milder compared to normal in terms of temperature.
I have backed off on the extreme cold over western Canada and shifted it farther north and up into Alaska as I think the La Nina will be stronger rather than moderate.
Should be plenty of snow in the BC mountains this season. I also expect an active storm track from the Midwestern U.S. through the Great Lakes and into New England. Despite the milder look, it looks like a lot of snow this season from the Upper Midwest through most of Ontario, Quebec, northern New England and perhaps New Brunswick.
Southern Ontario should be fairly stormy, but milder temperatures could bring more mixed precipitation and rain compared to normal.
Lake-effect snow farther inland away from the lakes should get off to a strong start early in the winter due to the above-normal lake temperatures, but then I expect below-normal lake-effect for January and February, especially off the eastern Great Lakes.
I am pretty confident that the winter as a whole will be a balmy one over the southern U.S. and into the Middle Atlantic, esp. January through February.
I will post my final (official) winter outlook during the third week of October. Things could easily change
