Overview
- Winter storm warnings and advisories span multiple states, with National Weather Service guidance and local forecasts pointing to localized totals up to 14 inches between Monday and Wednesday.
- Chicago-area officials highlight increasing confidence in freezing rain during Tuesday’s commute before a rapid switch to wind‑whipped snow and possible squalls Wednesday, with gusts topping 40 mph.
- Metro Detroit faces two rounds: a light morning snow/freezing drizzle, then a stronger late‑evening system bringing a rain/snow mix; the Thumb is under a winter weather advisory with 3–5 inches and a refreeze risk Wednesday.
- Across southeast Wisconsin and along I‑94, a transition zone will produce a messy mix with icy surfaces as temperatures briefly rise then fall Wednesday, followed by single‑digit to teens lows and subzero wind chills in spots this weekend.
- In the Northeast, coastal cities like Boston are forecast to see mainly rain as higher terrain in central and western New England holds snow, while Rochester expects a slushy inch or two before a changeover and late‑week lake‑effect bands.
