Overview
- After a milder Tuesday, a fast-moving system arrives Tuesday night into Wednesday with rain, freezing rain and snow, shifting by elevation and track.
- Chicago forecasters highlight increasing risk for freezing rain Tuesday evening, with gusts near 40 mph and a change to wind-whipped snow by Wednesday morning.
- The NWS has winter alerts across multiple states, with some locations projected to see significant accumulations through Wednesday and dangerous commutes in spots.
- Regional impacts will vary sharply: Detroit’s Thumb may see 3–5 inches, southeast Wisconsin faces icy conditions on frozen ground, and New England trends rain near the coast with snow in higher terrain.
- A reinforcing Arctic blast late week will drop temperatures sharply, bring sub-zero wind chills in parts of the Upper Midwest, and sustain additional lake-effect and clipper snow chances.
