A more active storm track is expected in November than we saw earlier in the season, with more opportunities for precipitation spreading from coast to coast. It’s likely that the B.C. coast and Atlantic Canada will be the primary targets for fall storms throughout the month.
As a result, folks across portions of southern and northeastern Ontario, as well as the northern half of Quebec, can expect near-seasonal conditions to kick off the month.
Meanwhile, below-seasonal conditions are favoured throughout Atlantic Canada, southern Quebec, and into eastern Ontario.

As November continues, above-seasonal temperatures will spread east, with mild conditions expected into southern Ontario and southern Quebec. Only B.C. and the East Coast are expected to have near-seasonal conditions through the middle and latter half of the month.
However, a big change is on the way towards the end of the month as we make an abrupt transition into early winter.
While the precise timing of this pattern flip remains uncertain, forecasters are eyeing the potential for widespread below-seasonal temperatures to spill across the eastern two-thirds of Canada during the final days of November and into December.
