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.
