The Met Office has said that thunderstorms could bring hail and heavy rain to parts of the South-West of England, and South-West Wales on Wednesday.
A yellow warning has been issued for these areas following a hot weekend with Tuesday being the hottest day of the year.
Met Office meteorologist Alex Burkill said, “The thunderstorms could bring lots of lightning, some hail, as well as some heavy rain, and with the half term there is an increased number of tourists in this area.
“The thunderstorms do then push north-eastwards into the Midlands and across more of Wales, but they also ease and break up, so these places will see some showers but they won’t be as intense.”
Burkhill added that Wednesday is likely to be even hotter than Monday and Tuesday which saw the mercury hit 28C, with some areas hitting up to 29C today.
Temperatures will slightly dip on Thursday with fine and dry weather, but thundery showers could hit in some areas of the UK.
