Weekly long-range weather pattern update

Excellent consensus for the overall weather pattern across much of North America for the week of Oct. 28 to Nov. 3. There looks to be a fairly amplified jet stream pattern with a ridge near the West Coast and a trough over Ontario, which will send chilly air down through the eastern Prairies. As usual, areas that are east of the mean trough can expect some wet weather.

There is much more uncertainty with the pattern after the 5th with some significant differences in the modeling, which is not surprising due to a lack of strong atmospheric signals.
