There is an increased threat for tropical systems to impact Atlantic Canada during fall 2012.
"With the warmer water off Atlantic Canada, any tropical systems will have a greater chance of maintaining strength compared to normal as they move northward. Look for at least one named storm to threaten coastal Nova Scotia or Newfoundland," AccuWeather Expert Senior Meteorologist Brett Anderson said.
More storms are expected to recurve, passing the U.S. and heading toward Atlantic Canada, especially during the middle of fall, Anderson added.
Above-normal precipitation is forecast for Nova Scotia and Newfoundland for the season with tropical impacts factored in. Rough, battering surf and damaging winds may be other threats.
The unusually warm ocean water off the coast of Atlantic Canada will influence warmer temperatures and humid conditions for the region.
Temperatures should also run above normal across much of Ontario and southern Quebec, including the major cities of Montreal, Quebec City, Ottawa and Toronto.
Less rain than usual is predicted for the Ottawa, Toronto and Windsor areas, following a dry summer across parts of Ontario.
Anderson is forecasting a later-than-normal frost or freeze for eastern Canada.
However, with above-normal water temperatures of the Great Lakes, there is a greater potential for more intense lake-effect snow outbreaks if enough cold air arrives.
Farther north, dry, mild weather may mean a slow start to winter sports such as skiing and snowmobiling across northern and central portions of Ontario and Quebec.
A predominantly northwesterly flow will promote a fairly calm and quiet fall for the Canadian Prairies. Near-normal temperatures and precipitation are expected.
"Winnipeg, Manitoba, and Saskatoon and Regina, Saskatchewan, will have a pleasant fall," Anderson said. After very wet weather recently, the dry and mild fall may be welcomed by residents.
Dry weather should also dominate southwestern British Columbia with below-normal temperatures across western Canada.
"Large highs coming down from Yukon will bring quick shots of chilly air into British Columbia this fall," Anderson explained. Departures of 1-2 degrees C (2-4 degrees F) below normal are possible for the season. Interior British Columbia may have an early frost or freeze as well.
Vancouver will be drier and slightly cooler than normal.
The latter part of the fall should please avid skiers and winter sports enthusiasts that frequent resorts in the western mountains as the British Columbia snow base should get established on schedule.
The weather threatens to interfere with search, rescue and cleanup operations in the wake of the major 7.8-magnitude earthquake that has killed thousands of people with the death toll mounting.
Damaging wind and hail as large as softballs have been the main threats, and will continue to be throughout the overnight hours.
Sunny skies and cooler conditions will be the rule this week in Chicago.
In wake of a chilly Monday with spotty showers, warmer and drier weather will settle in for much of the week ahead.
Temperatures will have their ups and downs across the Northeast this week, starting off on a cool note before milder air moves in for the middle of the week.
