Overview
- Many regions reached the 60s to low 80s on Tuesday, creating unstable air that supports rounds of showers and thunderstorms from Tuesday night into Wednesday.
- The Storm Prediction Center flagged parts of the Midwest and Great Lakes for a slight severe risk, with damaging winds and hail the main hazards and a low chance of an isolated tornado in a few spots.
- A strong cold front late Wednesday into Thursday will drop temperatures quickly and change rain to freezing rain and snow in Minnesota and Wisconsin, bringing a risk of slick roads and slower commutes.
- Chicago, Detroit, Pittsburgh, and Cleveland forecast multiple storm windows with some nighttime activity, so residents are urged to keep warning alerts on and check local NWS guidance for timing.
- In California, weak systems will clip the Bay Area with light showers that end a weeks‑long dry stretch, with most cities likely seeing less than a tenth of an inch before drier weather returns for the weekend.
