Overview
- A reinforcing surge of Arctic air is dropping temperatures fast, with single-digit and below-zero wind chills spreading into early next week.
- Widespread light snow Saturday is expected to total roughly 1–3 inches for many areas, with higher amounts favored in interior high terrain and rain mixing near some coasts.
- An offshore system late Sunday into Monday could clip the South Coast, Cape and Islands with additional snow, with timing likely after the Patriots game and low confidence on exact track and reach.
- Great Lakes and Midwest forecasts call for additional bursts of snow and slick travel, with reduced visibility reported or expected in parts of Chicago, Wisconsin, Michigan, Ohio and western Pennsylvania.
- Early next week turns sharply colder with lake-effect potential and sub-zero wind chills in spots, while the UK Met Office flags a possible late-month shift to colder, snowier conditions there.
