Overview
- The Met Office expects a weak weather front to bring light rain and cooler air across parts of the UK this weekend, but officials warn the change will be short lived and uneven in coverage.
- Weather models show a credible risk of another UK heatwave in late July and early August with localized peaks potentially reaching 38–39°C, a forecast that Met Office forecasters describe as uncertain and subject to change.
- Water supplies remain under pressure in Britain: Environment Agency regions have 'prolonged dry weather' declarations, Thames Water and others have imposed widespread hosepipe bans, and parts of Wales and the Upper Severn have been declared in drought.
- The US is facing a new heat dome that forecasters say will bring triple‑digit temperatures across large swaths of the central US and active NWS heat advisories and extreme‑heat warnings in Southern California and Central Texas.
- Tropical Storm Bertha is being monitored for possible effects on Texas rainfall and heat patterns, and public‑health agencies are urging vulnerable people to stay cool, hydrate and follow official warnings as services and wildfire risk are stretched.
