Overview
- Winter storm warnings and advisories span nine states, with the National Weather Service citing localized totals up to 14 inches through Wednesday as multiple Alberta clippers and 40–50 mph gusts sweep the northern tier.
- Chicago forecasters report increasing confidence in travel impacts starting Tuesday evening from freezing rain, with wind-whipped snow and squalls likely Wednesday as temperatures briefly rise then fall sharply.
- Across the Great Lakes, a messy rain–snow–ice transition is expected Tuesday night into Wednesday; metro Detroit faces two rounds (about 1–2 inches early, then roughly 2–5 inches north of the city with mixing south) and a refreeze risk by Thursday morning.
- Southeast Wisconsin sits near a rain–snow line with up to about 3 inches north of I-94 and icy spots where rain falls on frozen ground, while northern Pennsylvania is under advisories for 3–6 inches in the higher terrain and New England’s hills may see 1–3 inches as lower elevations turn to rain.
- The NWS issued a Freeze Warning for parts of south-central Texas with lows near 30°F, as fresh Arctic air pushes south and additional clipper disturbances are forecast to reinforce the cold into the weekend.
