Overview
- Across much of the U.S., a midweek warm-up is underway, with Thursday forecasts calling for highs from the 60s to 80s and mostly dry days before a shift to more unsettled weather.
- The U.K.’s brief mini‑heatwave near the mid‑20s C is fading as cooler Atlantic air moves in, with the Met Office flagging a thundery, windier spell and a notable drop in temperatures by the weekend.
- California forecasters cite a slow‑moving cut‑off low, which can drift away from the jet stream and linger, bringing rounds of showers and isolated thunderstorms through Sunday and a localized flooding risk where storms train.
- Great Lakes and Midwest cities such as Chicago, Detroit and Milwaukee warm into the 60s Thursday, face gusts up to 30–45 mph, then see showers return Thursday night into Friday before a drier, much warmer Sunday.
- New England rebounds into the 60s Friday, cools slightly over the weekend, and could surge again early next week, while the Storm Prediction Center highlights a 15% severe risk on Tuesday for parts of the central U.S.
