Key Highlights
- Lancaster County is expected to receive up to 30 inches of snow this winter season.
- The winter weather forecast predicts a period of severe cold beginning around the Christmas holiday due to a weak stratospheric polar vortex.
- This forecast suggests Lancaster County may see its first significant snowfall since four consecutive below-average seasons.
- Expert predictions indicate that while temperatures will remain several degrees above average through February 2026, there could be wild temperature swings during the winter season.
Lancaster County’s Winter Outlook: Snow and Chilly Weather
Kyle Elliott, a meteorologist from Millersville University, has released his winter weather forecast for Lancaster County. The forecast outlines a potential snowfall of up to 30 inches this season, along with bone-chilling cold temperatures that could begin around the Christmas holiday.
Expectations for Snowfall
The county is likely to see between 20 and 30 inches of snow during the winter season from October through April. This prediction contrasts sharply with recent years where Lancaster County experienced four consecutive seasons of below-average snowfall: 16.5 inches in 2024-25, 18 inches in 2023-24, 0.9 inches in 2022-23, and 15 inches in 2021-22.
The long-term seasonal average snowfall is 27.5 inches, according to the weather center. This year’s forecast suggests that while it may feel like a lot more than recent years due to an extended “snow drought,” the actual amount of snow is predicted to be only average for December and January.
Temperature Projections
Elliott predicts wild temperature swings at times this winter. A multiweek period of severe cold from mid-December through early January, as a result of a weak stratospheric polar vortex, will bring frigid temperatures to the region. However, February 2026 is expected to see mild temperatures return.
The last five days of February in previous years have seen temperatures reach into the 50s and 60s.
Normal high temperatures for those dates are mid-40s. These higher-than-average temperatures will lead to many rain showers and “changeover storms,” where precipitation starts as snow but transitions to rain or a wintry mix.
Expert’s Perspective
Elliott, in his forecast, warns that the region is likely to see at least one moderate snowstorm of 6 to 10 inches during mid-December into January. While it remains difficult to determine how much cold and snow the region will see in March, there is a possibility of significant cold snaps.
According to Elliott, “Get ready for a wild ride this winter, especially in terms of temperature.” This prediction suggests that residents should prepare for both snow accumulation and extreme changes in weather patterns during the upcoming season.
