Overview
- A fast-moving system brings widespread light snow of roughly 1 to 3 inches to parts of the I-95 corridor on Saturday, creating slick travel in spots from Washington, D.C., to Boston.
- Lake-effect bands continue to hammer the Great Lakes snowbelts, with more than 26 inches reported near Buffalo and additional localized heavy bursts expected.
- Several clippers keep snow chances going through MLK Day, and a quick coastal system late Sunday into Monday remains track-dependent with outcomes ranging from a dusting to plowable amounts along parts of coastal New England.
- An incoming Arctic surge early next week is forecast to produce the coldest readings of the season, including single-digit highs in parts of the Great Lakes and sub-zero wind chills that could prompt advisories.
- Farther south and along some coastal areas, precipitation may mix with rain or stay minimal, and recent warmth in places like the Gulf Coast and southern Colorado will give way to a sharp cooldown.
