She said: "As we move into the middle of the week we start to see an increasing risk of thunderstorms developing, particularly in parts of England and Wales, and the rain is such that it could cause some local disruption.

"This is the sort of rainfall that could cause surface water flooding and heavy rain that takes a while to clear away.

"There could also be some lightning potential for hail and gusty conditions."

She added a return to cooler temperatures is expected by next weekend.
