UK's weather forecast
The entire UK is covered by Met Office yellow weather warnings for thunderstorms, with Monday and Tuesday to bring chaotic rainfall, thunder, hail and lightning. The country is currently baking in heatwave conditions, with up to 38C possible on Saturday.
The Met Office warns some places are likely to see severe thunderstorms early next week - however there is significant uncertainty in location and timing.
Forecasters say the storms are "increasingly likely to develop over the south of the UK or nearby continent late in the weekend or early next week".

They will "generally track north or north-westwards, potentially affecting all parts of the UK at some points during this period."
The Met Office explained the hot weather from Saturdayonwards will trigger the thunderstorms, and some could see large hail.
Storms are forecast to produce heavy rainfall and frequent lightning could reach further north at times over Scotland and Northern Ireland.
Where the storms occur, rainfall totals of 1.1 to 1.5 inches (30 to 40mm) could fall in an hour, with some locations potentially receiving 2.3 to 3.1 inches (60 to 80mm) in three hours, although these will be fairly isolated.

The warnings are in place from midnight on Monday through to 11.59 pm on Tuesday.
More information on exact areas and impacts is expected over the next few days.
BBC Weather forecaster Alina Jenkins explained how a low pressure close by, combined with the hot weather could spark intense thunderstorms.
Ms Jenkins said: "Really as we start to look into next week, we are still holding on to some fairly high temperatures, it is going to be feeling warm for many of us, and also we have an area of low pressure in the Bay of Biscay."
“This combination of low pressure and above-average temperatures is a good recipe for thunderstorms. Such as their nature, they are going to be hit and miss."
"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.”

On Saturday, highs of 37C were expected across the south of England, with up to 38C possible in some places.
The Met Office has now confirmed the next few days of weather will reach its heatwave threshold. However Brits should make the most of the hot weather before thunderstorms strike next week.
Netweather forecasters have also warned of thunderstorms, revealing the hot weather will bring complications.
An area of high pressure will be a strong influence on the weather throughout, bringing plenty of sunshine. However, the high pressure won't be directly overhead, with lower pressure not too far away over the continent.

This will allow the atmosphere to de-stabilise at times, with cloud often bubbling during the heat of the day, allowing for some sharp showers and thunderstorms to develop.
Initially, as this week ends and we move through the weekend storms are likely to be isolated and infrequent, but as we move into next week, the risk will increase.
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."

Highs in the southeast of England at a hot 31C and across much of England ranging 25 to 29C and further north and west highs at around 19C.
Europe's weather forecast
BBC Weather has forecast flash flooding and thunderstorms to bombard parts of Europe during the heatwave.
BBC Weather forecaster Stav Danaos claimed the hot weather is set to continue for most areas in Europe. However, he said the Balkans will experience some flash flooding and thunderstorms over the weekend. As the new week begins, parts of western Europe will also see thunderstorms and showers.

Mr Danaos said: "Thunderstorms, heavy rain and flash flooding are issues expected across the Balkans the next few days."
"The remnants of the storms and heavy showers continuing across the Balkans."
"They will be extending a little bit further southwards."
"In the next 24 hours it looks like most of Greece will be in the firing line for some of these thunderstorms as well as southern Italy."
The BBC Weather forecaster explained across the rest of Europe the heatwave is set to continue into the weekend.

He said: "Elsewhere, the story is about the heatwave in central, northern and western Europe."
"There will be pretty typical summer temperatures across the eastern Mediterranean."
"Then as we drift into the Balkans is where we will have those thunderstorms."
"Into central and eastern Europe there will be high temperatures for Germany and parts of Poland."
"That heat will get into southern Scandinavia as it is wetter and cloudier towards the north."
The weather forecaster noted that towards the end of the weekend much of central and western Europe will still be experiencing hot temperatures.

However, there will be an increased chance of rain and thunderstorms.
He said: "As we head on into Sunday across central parts of Europe we will start to see threats of showers and thunderstorms developing.
"That is going to be the theme as we head on into the new week."
"It will stay pretty hot and humid to start with, the chance of thunderstorms will increase for London and Paris through the week."
