While November ends on a warm note in the eastern US, there are changes unfolding across the Northern Hemisphere that will likely bring a widespread very cold air mass into the US next week. The cold air mass is first going to arrive in Alaska this upcoming weekend with some spots in that state plunging to 40 degrees below zero. After that, the cold air dives into the western US during the first half of next week, and then it will likely blast into the eastern US late next week. By the time December 10th rolls around, there may be colder-than-normal conditions all the way from Alaska to the southeastern US.
Record cold coming to almost entire USA
