After two cool, wet summers, 2010 saw a return to a more “traditional“ Canadian summer with warm temperatures and near normal precipitation. The Arctic saw higher than normal temperatures, part of a growing trend for that area. Eastern Manitoba and parts of the Arctic experienced higher than normal precipitation. The rest of Canada may have experienced periods of hot temperatures and wet weather, but in the end, the summer averaged out to be fairly normal.
Nice start to fall
Most of Canada should expect a slow start to fall with summer weather extending well into September. The El Niño conditions experienced across Canada last winter have shifted over the summer towards La Niña but the momentum of the warm summer pattern we've had is forecast to continue; at least initially. This trend continues through the fall leading to a more “traditional” cold Canadian winter than was experienced last year. Through October and November, a west to east cooling trend is expected with more pronounced effect in southern parts of Ontario and Quebec where November may be colder than normal. See below for provincial and regional breakdowns.
Temperatures for the fall period are expected to be near normal with the exception of the north coast of BC where temperatures are expected to be below normal. The north coast will also experience lower than normal precipitation while the south coast will see higher than normal precipitation. The rest of the province can expect near normal precipitation.
Alberta and Saskatchewan
Both provinces can expect a very typical fall season with near normal temperatures and precipitation.
The southeast part of the province including the city of Winnipeg will experience higher than normal temperatures and precipitation during the fall. The rest of Manitoba will see near normal fall conditions.
Northern Ontario can expect higher than normal temperatures and precipitation this autumn. The rest of the province will see near normal temperatures and precipitation.
The extreme north of the province will experience warmer than normal temperatures and near normal precipitation. The rest of Quebec can expect near normal fall conditions.
Temperatures across the Maritimes and Newfoundland will be near normal this fall. Nova Scotia and central and eastern Newfoundland will experience higher than normal precipitation. This is in part due 2010 Atlantic hurricane season which is heating up with the increased potential for tropical storms to move north along the Eastern Seaboard towards Atlantic Canada rather than moving into the Gulf of Mexico. Precipitation amounts will be near normal for the rest of Atlantic Canada.
Southern Nunavut will experience above normal temperatures with higher than normal precipitation for central Nunavut. The Yukon and Northwest territories will experience a near normal autumn season.
