- National Weather Service offices have posted frost advisories and freeze warnings into parts of Florida, with colder conditions expanding across the Southeast this weekend into early next week.
- Chicago forecasts call for subzero lows Saturday night with wind chills of minus 15 to minus 25, and daytime highs near 10 on Sunday as dangerous cold peaks in the Midwest.
- Multiple quick‑hitting clipper systems and lake‑effect bands are bringing intermittent light snow and flurries to the Great Lakes, Midwest and Northeast, with localized travel impacts.
- A brief late‑week warm spell in the Deep South ends as a strong cold front pushes through Sunday, dropping temperatures rapidly and introducing freeze risk into early Monday.
- Forecasts signal a quick moderation by midweek next week, with many areas rebounding toward seasonable or milder temperatures after the Arctic surge.
