The build of heat and humidity today is expected to set off further severe thunderstorms tonight and later on Saturday. The Met Office have issued rainfall warnings because of the potential for disruption throughout Saturday.
Tomorrow will possibily be one of the hottest days for many years, and that's prompted Public Health England to issue an alert about the dangers of the heat - particularly to the very young and the elderly.
The Met Office also says we could have very heavy downpours and thunderstorms this weekend.
