While 2024 has been warm across much of the country, and several records were tied again in Florida on New Year's Eve (see above), big changes are arriving from the north in the coming days as we enter 2025.
The Great Lakes will be one of the first regions of the country to feel the bite of colder air, with high temperatures running well below average by the end of the week.
Although not quite as pronounced initially, the Northeast will also feel temperatures drop into the weekend.
A deep upper-level trough will open the door for colder air to move in from the north. As we head deeper into January, expect further shots of arctic air.
While there is some confidence in above-average temperatures across the Pacific states, there is high confidence in below-average temperatures for the eastern half of the country through January 10th.
