Major Cold Snap To End 2025

Much colder air is expected to arrive next week (late December 2025) in the central and eastern U.S. after some unseasonably warm days leading up to Christmas, bringing a return to colder, more seasonal winter conditions with potential for gusty winds and light snow/freezing temps, particularly in the Appalachians, with a strong Arctic blast possibly building into January. 

What to Expect:

  • Warm-up then Cool Down: Enjoy mild temperatures now, but expect a shift as a cold front brings colder, below-average temps by early to mid-next week.
  • Arctic Air: A significant cold air mass from northern Canada is moving in, bringing the coldest air so far this season.
  • Snow Potential: The cold air, combined with warmer lake waters, could trigger lake-effect snow (especially near Great Lakes) and even some slushy snow in the Appalachians (NC, TN, WV) from Sunday into Monday.
  • Hazardous Travel: Sudden drops in visibility from snow squalls could create dangerous driving conditions.
  • Beyond Christmas: Some forecasts hint at even colder air and more winter weather opportunities extending into January. 

Where to Watch:

Midwest, Northeast, and Appalachians are key areas for this cold snap and potential snow.
