Overview
- Temperatures jumped Monday across the eastern U.S., with highs trending into the 60s and 70s and pockets near 80 degrees in some southern areas.
- Multiple outlets expect several rounds of showers to develop from Tuesday into Wednesday, including scattered thunderstorms as a frontal system approaches.
- The Storm Prediction Center highlights a Marginal to Slight risk for severe weather late Tuesday into Tuesday night in parts of the Great Lakes and Midwest, with damaging wind, large hail, heavy rain and an isolated tornado possible.
- A strong cold front is set to push through late week and flip the pattern, dropping highs into the 40s and 50s by Thursday and Friday with lingering showers and some higher‑elevation wintry mix.
- Forecast confidence hinges on the front’s timing Wednesday, which could still allow brief warmth in spots, while coastal areas stay cooler and pollen levels run high during the gusty warm spell; in the UK, the Met Office also points to a milder turn from Tuesday.
