The Met Office has issued a yellow weather warning for thunderstorms, in place from Monday to Wednesday.
After a scorching, sizzling weekend with some of the hottest temperatures of the year, it seems that the weather is set to take a turn for the worse.
The forecaster says some places are 'likely to see severe thunderstorms', and there could be localised flooding, lightning strikes, damage to buildings and large hail.
The Met Office also said that there is a slight chance power cuts could occur, and that fast flowing or deep floodwater could cause a danger to life.
What the Met Office says about thunderstorms
Some places are likely to see severe thunderstorms early next week - but there is significant uncertainty in location and timing.
There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes and large hail.
Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to public transport.
Spray and sudden flooding could lead to difficult driving conditions and increased chance of accidents.
There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost

What is the forecast for Leeds?
A mix of cloud and rain on Monday with temperatures maxing out at about 25C.
On Tuesday, the temperature will actually increase to 27C, where it will stay throughout Tuesday and into Wednesday. So there could still be plenty of hot, clammy restless nights ahead.
The Met Office itself admits that it isn't clear exactly when the thunderstorms are set to crackle into our skies, which is why it has issued a wide-reaching warning which is a touch vague on timing.
Although there isn't any specific day or time that the thunder could strike, Leeds could reasonably expect thunderstorms at any point between Monday and Wednesday.
Otherwise, the forecast is hot with spells of rain and cloud.
