Winter Weather in Southern Berkshire, Massachusetts

Sub-freezing temperatures ahead of an approaching warm front resulted in a period of accumulating freezing rain for all of western Massachusetts during the late afternoon and evening hours on December 28, 2025 into the overnight or morning hours on December 29, 2025. As temperatures rose above freezing, precipitation eventually changed to plain rain for many areas. Flat ice accumulations of a light glaze to 0.25 inches occurred which resulted in some slippery travel conditions and isolated power outages.
