Looks like another pattern shift as we head into November. A ridge of high pressure is projected to build over the Gulf of Alaska in early November which should force colder air down into the Prairies and perhaps BC for a time, while a wetter pattern takes over farther to the east.
This pattern could also produce some snow opportunities for the Prairies and into northwestern Ontario.
