Thunderstorms across parts of the UK bring hail, lightning and flash-flood risk

Following a summer marked by record heat and widespread drought, the UK faces a spell of wet weather that will concentrate on north-west England, Northern Ireland and southern Scotland. Showers are likely to become thundery, bringing hail, lightning and the possibility of flash flooding in those areas, whereas south-east England may see little rain. Tuesday will start wet in many northern and central regions, with Scotland and Northern Ireland remaining showery throughout the day.

By Wednesday, a low-pressure system will produce sunny intervals mixed with frequent showers in the north-west, while Thursday’s drifting low will spread thunderstorms more widely, though some of the driest regions may still miss the rain. Cooler Arctic air will accompany the system, dropping temperatures to 13-22 °C, a return to seasonal averages after recent warmth. The Met Office notes that while the rain may not end the drought, it could alleviate short-term flood risks.
