Some places will remain dry, but where thundery showers do occur, they will bring frequent lightning, gusty winds, potentially some large hail, as well as brief spells of heavy rain.

Forecasters at the Met Office warned that 15 to 25 mm of rain may fall within an hour, with a very small chance of 30 to 40 mm falling in three hours, most likely across southwest England..

The Met Office also said that, while there is some uncertainty in the details , scattered showers and thunderstorms are likely to develop and spread northwestwards at times later on Friday night and through Saturday.

While much of the time it will be dry, and not all places will see these, where they do occur 20-40 mm could fall in less than an hour, with a small chance of isolated accumulations of 50-70 mm over the course of a few hours.

In addition, hail and frequent lightning may accompany the most intense storms, especially during Saturday afternoon and evening in parts of the Midlands, southern England and east Wales.
