Ms Jenkins stated there are red warnings across France and Belgium for the high temperature forecast for Sunday. The BBC Weather Europe meteorologist added that the wildfire risk across Portugal remained high.
Ms Jenkins said: “The main focus is on the heat across the continent.
“This will begin to trigger thunderstorms over the coming days.
“Thunderstorms are still in place across the Balkans as we head through Sunday.
“There will be a couple of heavy showers through parts of Greece and eastern areas of Turkey as well.
“There will be some developing through France on Sunday.”
She added: “Meanwhile the wildfire risk across Portugal remains high.
“We have got a red warning for the high temperatures across France and Belgium.
“Some intense heat by day, very muggy by night.”
“But, there is a signal that some of these thunderstorms could bring some significant amounts of rain in just a short amount of time.
“That is something to keep an eye on through the early part of next week.”
Deputy Chief Meteorologist, Chris Bulmer, said of the oncoming thunderstorms: “The hot airmass will remain over much of England and Wales until early next week, so we’ll continue to see maximum temperatures in the low to mid-30s Celsius as the heatwaves continues.
“It looks like the heatwave could break on Tuesday and Wednesday as the risk of thunderstorms increases for many areas, although at the moment it’s a bit too early to say for certain, so our advice is to keep up to date with Met Office forecasts day-by-day.”
