A map from the National Weather Service (NWS) Climate Prediction Center shows that every single state is expecting above-average temperatures for the eight- to 14-day outlook, which goes through December 22, the Sunday before Christmas.
Warmer-than-average winter temperatures are expected to begin across the U.S. over the next week. Outlooks show that all states are expecting at least a 33 percent chance of warmer temperatures between December 14 and December 18, with that chance jumping to 70 percent chance across the western U.S. from December 16 to 22. The weeks-long warming trend has already started, with several cities across the U.S. experiencing above-average temperatures on Monday.
"Well above average temperatures will overspread the central and eastern U.S. as cold air surges into the western and then central U.S.," the NWS Weather Prediction Center said in its Monday forecast.

Although it's too early for meteorologists to issue accurate Christmas Day weather forecasts, the climate trend implies that temperatures will be above average, meaning that precipitation that does fall could be rain rather than snow, depending on the location.
Based on the outlooks, much of the U.S. expects to be dry for the week ending on December 22, except for the far Northeast, the Pacific Northwest and some Southern states, including Texas and parts of Florida.
NWS Climate Prediction Center meteorologists are anticipating the warm temperatures as the NWS shared historical data that shows the chances of states with a White Christmas last week. However, should temperatures continue trending warm, states that typically see a White Christmas might not this year.

The warming trend that begins this week follows a bout of cold, high pressure that will move through the Northeast. Once that system moves off the coast over the weekend, NWS Weather Prediction Center meteorologist Brian Hurley told Newsweek that warm, southerly flow will move in, bringing higher temperatures.
The warmer temperatures will begin in the western U.S. and southern Plains by later this week.
"By Sunday, much of the nation from west to east will be near normal or above normal with temperatures, with the highest departures above normal in the central U.S.," Hurley said.
One of the states with the greatest deviation from average temperatures this time of year is Alaska. As of Monday, Anchorage, Alaska, is seeing the highest temperature for December 9 since 2019 with a high of 42 degrees, according to data from Processed Webdata by Pricing Culture sourced from the National Weather Service (NWS) and provided to Newsweek.
At one point last week, colder-than-average temperatures in New York meant that New York City was the same temperature as Anchorage.
"The current weather situation in Anchorage, AK is characterized by unseasonably warm temperatures, with a deviation of 14.5°F from the 5-year historical average," a statement with the data said. "This deviation represents a significant 70.73% increase from the average temperature on December 9th."
