The Met Office has issued an amber weather warning for the south of England over the expected level of rain.
Several areas of heavy, thundery showers will develop across the south on Friday night before moving northwards on Saturday.
People should expect thunderstorms and torrential rain with lightning, large hail and strong winds.
The bad weather also means the possibility of flooding is possible because of surface water.
For many it will be fine, dry and it will turn hot and humid across southeastern, central and eastern England with highs of 33 Celsius (91F).
Some thundery showers are expected across central, then northern parts of the UK as we head through the day.
However, it will be cloudier and cooler in the southwest. Thunderstorms are expected to spread from the south later this evening.
