by Washington, D.C. — After a rough opening to winter that brought persistent Arctic air, record-setting cold, and multiple snowstorms, weather patterns across the United States appear to be shifting. Federal forecasters now say a broad warmup is expected to take hold across much of the Lower 48 as Christmas approaches, potentially melting recent snowfall and lowering the odds of a classic White Christmas for many areas.
New guidance from the Climate Prediction Center (CPC) shows a strong signal for above-average temperatures in late December, signaling a clear departure from the harsh conditions that dominated earlier this month.
Early winter arrived with intensity
The start of winter was anything but quiet. Large portions of the country endured severe cold outbreaks and widespread snowfall, driven by repeated surges of Arctic air linked to disruptions in the polar vortex.
Several locations saw record or near-record low temperatures, while successive snowstorms caused travel headaches, school closures, and disruptions to daily routines. Snow quickly built up across wide areas, raising expectations among many that a snowy holiday season was on the way.
That momentum, however, now appears unlikely to last through Christmas.
Forecasts show a nationwide warming trend
According to the CPC’s latest outlook, most of the Lower 48 is favored to run warmer than average through the final days of December.
Meteorologists attribute this shift to a strong ridge of high pressure over the western United States, which has already led to unusually mild weather in parts of the West, including areas of the Pacific Northwest and the Rockies.
As the atmospheric pattern adjusts in the coming days, forecasters expect this ridge — and the warmer air associated with it — to expand eastward, allowing milder temperatures to overspread the Midwest, Ohio Valley, and Northeast.
Snow cover may fade across central and eastern states
Many regions from the central Plains into the Mid-Atlantic, including states from Iowa to Pennsylvania, are currently dealing with lingering snow from recent storms. But with temperatures forecast to climb above seasonal norms, snowmelt is likely to accelerate as Christmas week nears.
Lower elevations and urban areas are especially vulnerable to losing snow cover, which could leave little to no snow on the ground by Christmas morning in many communities.
Forecasters also note that melting snow could lead to slushy conditions and wet roads, particularly if nighttime temperatures dip back below freezing.
White Christmas prospects becoming limited
For a location to officially record a White Christmas, there must be at least one inch of snow on the ground by 7 a.m. on December 25.
Based on current projections, the best chances of meeting that requirement appear limited to far northern and higher-elevation areas, including:
- The Rocky Mountains
- Far northern Minnesota
- Parts of Wisconsin and Michigan
- Interior and mountainous sections of New England
Outside these regions, sustained snow cover by Christmas Day looks increasingly unlikely.
Big Northeast cities face long odds
For major cities in the Northeast, the forecast does little to revive hopes of a snowy holiday.
Places such as New York City, Philadelphia, and Washington, D.C. have not seen a White Christmas since 2009, and forecasters say this year is trending in the same direction.
Factors such as urban heat retention, lower elevation, and proximity to milder coastal air make it difficult for snow to stick around in these metro areas, even during colder winters.

Why winter patterns are easing
Weather experts explain that winter rarely follows a straight line. Early-season cold does not guarantee a snowy or frigid holiday, as atmospheric patterns frequently shift.
As the polar vortex weakens and retreats northward and the jet stream becomes more west-to-east oriented, milder Pacific air can more easily move across the country. This setup favors temporary moderation in temperatures, even if colder shots still occur later.
Although La Niña conditions remain in place this winter, forecasters note that La Niña does not rule out prolonged mild stretches, especially when reinforced by high-pressure systems.
Holiday travel outlook improves with milder weather
The warmer trend could prove beneficial for millions of holiday travelers. Milder temperatures generally reduce the risk of widespread winter storm disruptions, especially at major airports across the Midwest and Northeast.
While localized weather issues can still develop, forecasters say the overall pattern looks more travel-friendly compared with the stormy start to the month.
Outlook could still change
Meteorologists caution that long-range forecasts are not set in stone, and small shifts in the jet stream could still change conditions for certain regions.
Residents are encouraged to keep an eye on updated forecasts, especially if holiday travel or outdoor plans depend on the weather.
For now, forecasters say the signal is clear: after a fierce start to winter, a milder phase is likely to arrive just before Christmas, reshaping holiday weather expectations for much of the country.
