B.C. Fall Weather Outlook
Moving into the transitional fall months of September, October and November, Canadians can expect the developing El Niño conditions in the Pacific Ocean to have an impact on the North American weather patterns for the next six to twelve months. The jet stream is forecast to take on more of a zonal west to east pattern this fall, meaning a more rapid flow of systems across the country. Overall, the jet stream will trend further north for the beginning of the season, however as the season progresses, expect it to move south as fall comes to a close. Overall, Canadians can anticipate temperatures from British Columbia to Ontario to be above normal. Near normal precipitation is expected for most of the country with a few pockets of above normal precipitation. Normal temperatures or precipitation are an average based on 30 years of data.
'The jet stream pattern we saw throughout the summer months is gradually transitioning, and our seasonal forecast team is predicting above average temperatures this fall for nearly all of Western Canada,' said Chris Scott, Forecast Operations Manager with The Weather Network. 'Many Canadians in Eastern Canada have been hoping the cooler than normal summer temperatures means that summer has been delayed into the fall months – while temperatures are forecast to be close to normal, there is an opportunity for some stretches of warm weather in the first half of the season.'
British Columbia: Coastal areas of British Columbia can expect near normal temperatures for the next few months. Interior and eastern portions of the province will see above normal temperatures for the season. Pacific storms moving from the coast through the central Interior will bring above normal precipitation.
