The Fall Outlook shows temperature patterns experienced this summer should persist with above normal temperatures expected in B.C., parts of Alberta and southern Nova Scotia and below normal temperatures from the eastern Prairies into Quebec. The Weather Network’s meteorologists expect a typical transitional weather pattern over the next three months, but note that some early cold air is already on the map.
“Fall is the season where we usually see the most dramatic temperature and precipitation changes from month to month as we transition towards winter,” said Chris Scott, Chief Meteorologist at The Weather Network. “We’re already seeing that extreme seesaw of temperatures starting to affect southern parts of the country; the wild fall temperature ride is off to an early start.”
B.C.
As was the case in the summer, British Columbia is expected to continue experiencing above normal temperatures this fall and near normal precipitation for most of the province.
The Prairies
Most of Alberta and Saskatchewan will experience near normal temperatures and precipitation. East-central Saskatchewan and Manitoba should expect below normal temperatures, with some of these areas seeing above average precipitation.
Central Canada
In Ontario and Quebec, residents should expect a more or less similar continuation of this summer’s weather pattern, with generally near to below normal temperatures and near to above normal precipitation anticipated this autumn. As is typical for the fall, September into October will have stretches of warm weather nevertheless.
Atlantic Canada
Overall, near normal temperatures are expected for most of the Maritimes and Newfoundland. As the height of Atlantic hurricane season approaches, residents should keep an active lookout for severe weather.
The Weather Network’s Winter Preview
Meteorologists are monitoring developing El Niño conditions in the Pacific Ocean, which generally have an impact on late-fall and early winter weather in North America. While El Niño can often mean a warmer winter for Canada, that’s not necessarily the case this year. The Weather Network meteorologists are favouring a weak El Niño developing, which could result in a continuation of the patterns experienced this past summer and anticipated for this autumn. If a weak El Niño develops as forecasted, the odds favour winter temperatures to be on the lower side of normal from Manitoba east to Quebec, with British Columbia seeing above normal temperatures.
“El Niño doesn’t necessarily equal warm weather for Canada,” said Scott. “History tells us that a weak El Niño centred more across the central Pacific can produce colder than normal winters across central and eastern Canada. The possible weak El Niño developing for this winter is one of the key factors our forecast team is monitoring.”
The Weather Network will release its complete Winter Outlook in late November with additional details and forecasts for each region.
