Long-range pattern update into mid-December

By Brett Anderson, AccuWeather senior meteorologist

Published Nov 18, 2022 11:29 AM EDT | Updated Nov 18, 2022 11:29 AM EDT

Copied

Unseasonably cold air continues to cover a significant portion of North America as a large, broad trough continues to sit over the continent. This trough will finally begin to lift out next week, which will allow milder air to initially surge back into the Plains and Prairies. Farther east, the trough will hang out for a bit over Atlantic Canada, which will keep much of northeastern Canada and Quebec in the cold air before things start to modify back to normal.

This upcoming pattern may also favor more northwestern Atlantic coastal storms, which may bring some snow opportunities to Atlantic Canada.
