Weather patterns in the United States are set to undergo a significant transformation following an incoming snowstorm. Forecasters anticipate a drastic shift from bitter cold to warmer temperatures across much of the country.
Upcoming Weather Changes
Beginning on the weekend of December 13, a winter storm will bring light to moderate snowfall to central and northeastern regions. Some areas may receive up to six inches of snow. This storm coincides with a wave of arctic air moving through the country.
Arctic Blast and Its Exit
The prolonged cold snap is expected to last just over 24 hours. AccuWeather Senior Meteorologist Brett Anderson noted that despite the quick onset of harsh conditions, a significant warmup will follow, affecting central and eastern parts of the U.S. next week.
Warm Temperatures on the Horizon
On the western side, regions are already experiencing temperatures 15 to 25 degrees above average, as reported by the National Weather Service. This warm trend is projected to advance eastward, reaching many areas by December 18.
Regional Temperature Forecasts
- High Plains: Temperatures may reach the 60s in western Nebraska and South Dakota.
- Texas: Highs could approach 80 degrees.
- Midwest and Northeast: Daytime temperatures may climb as much as 30 degrees, moving from the 20s to the 50s between December 15 and December 18.
Implications for a White Christmas
As temperatures rise, the likelihood of a white Christmas, defined as having at least one inch of snow cover on December 25, is uncertain. The increasing warmth could melt existing snow, potentially impacting winter sports conditions. Forecasters continue to monitor future cold fronts that may follow the warmup.
Historical Context
Historically, the best chances for a white Christmas are found in areas such as Alaska, Minnesota, Maine, upstate New York, Idaho, and specific mountain regions. This data, compiled by the National Oceanic and Atmospheric Administration, offers insights based on climate trends from 1991 to 2020.
As the weather evolves, residents are encouraged to stay informed about local forecasts and potential changes in winter conditions.
