Slow-moving, thundery showers may lead to locally torrential downpours with the risk of frequent lightning according to the Met Office, who have issued a yellow weather warning for tomorrow and Friday.
A front coming from the Atlantic will merge with warm, unstable air over the country to bring the risk of 30-40mm of rain in just an hour in places and more than 50mm in a few hours. Whilst the vast majority of the country will have much less than this, it could cause disruption, especially if heavier bursts coincide with urban areas.
Forecasters say the main risk period is during tomorrow afternoon and early evening, though a few thunderstorms are likely to rumble on into the night.
The warning is in place from 14:00 tomorrow (Thursday) until 19:00 on Friday evening.
