A forecaster at the Met Office said: “Scattered thunderstorms are expected to affect parts of south-west and southern England this evening, moving north quickly across the UK overnight, clearing Scotland and eastern England by mid-morning on Wednesday.
“Although some places will miss the thunderstorms altogether, where they do occur there is the potential for frequent lightning, hail and gusty winds, as well as sudden downpours in a few places.“
The warnings come as Merseyside enjoyed its hottest days the year with temperatures reaching near the 30C mark.
After the thunderstorms the heatwave will continue as temperatures could get even hotter on Thursday.
Merseyside could see temperatures over 30C and some parts of the country could see the UKs hottest weather ever.
