Overview
- An official Met Office yellow warning flags a swathe of heavy rain from Wednesday night into Thursday with 20–50 mm possible in places and a chance of gales, bringing travel disruption and localized flooding risks.
- A colder northerly flow is expected late week with temperatures slipping below average and the potential for wintry showers over Scottish high ground after winds focus along eastern coasts on Friday.
- Longer-range model maps from WXCharts depict a potential early-November snow band, though this remains a conditional, model-based outcome that differs from official guidance.
- In the US Great Lakes and Northeast, forecasters expect two rounds of rain through Wednesday with gusts of 30–40 mph in spots, lake-effect showers midweek, and highs falling into the 50s before a drier, cooler stretch.
- Regional US updates highlight the first possible snowflakes over higher central Pennsylvania terrain, cooler and drier air already reaching Southeast Georgia and the Lowcountry, and frost potential in parts of the Appalachians.
