Heavy showers and thunderstorms are moving across large parts of the UK on Thursday, prompting a Met Office yellow warning for northern England and north Wales. The weather system, driven by low pressure, is expected to bring torrential rain, hail, and thunder as it shifts south and east throughout the day.
By the numbers
Rainfall and flooding risks
The Met Office warns that 15-20mm of rain could fall within an hour in affected areas, with six-hour totals potentially reaching 30-50mm. Flash flooding is a particular concern in regions where the ground remains hard from the recent hot, dry summer. While Scotland and Northern Ireland will also experience showers, they are expected to be less intense.
Driving conditions and drought status
Motoring experts have cautioned that the return of rain after a long dry period creates slippery road conditions. Rod Dennis of the RAC noted that oil, fuel, and rubber deposits on roads can create a greasy surface, increasing the risk of skidding. Despite the current rainfall, experts warn that the drought conditions affecting much of the UK will not end immediately, as replenishing water stocks requires a sustained period of persistent rain.
Temperature drop
Temperatures are forecast to fall, with Thursday expected to be the first day since June 29 where temperatures do not reach 25C anywhere in the UK. Highs on Thursday are expected between 13-23C, with even cooler conditions forecast for Friday. Nighttime temperatures are also expected to drop into the single digits, with some areas in Scotland and northern England potentially seeing lows of 3-4C.
