Forecasters have warned that a cyclone might reach the UK this week, bringing heavy rain, hail, and thunderstorms.
Because the jet stream is positioned to the north, the first part of this week will be quite fine and settled for the majority of the country, as high pressure dominates the weather.
Cyclones in the UK can cause heavy rain, and thunderstorms
However, the jet stream is predicted to drop south on Friday and over the weekend, bringing low pressure to the coastlines and making the weather more volatile, as per Independent.
The Met Office has predicted that two low-pressure centers, which it has dubbed "cyclones," will travel towards the UK, bringing severe rain.
"We have one that will try to push in from the northwest, and another from around the Bay of Biscay that will try to push in from the south," according to Jonathan Vautrey, a Met Office meteorologist.
He added that it is unclear whether one or both of those low-pressure centers will relocate across the UK.
Though the western part of the nation is expected to get the most rain, Vautrey warned that heavy weather might also affect certain eastern districts.
He went on to say, "Friday may see the first evidence of the low-pressure centers, notably the northwestern one moving through western Scotland and into Northern Ireland."

Numerous forecasts indicate an unstable September with much-needed rain on the way.
The Met Office, British Weather Services, Weather Outlook, and now, NetWeather have all weighed in on reports that autumn will arrive in the next few days.
The hot and humid weather will begin to cool, with low pressure forming by Saturday, September 3.
A GFS weather model, according to NetWeather, depicted a southerly flow of low pressure and moist air reaching the UK with "showery bands of rain, wet and overcast flow off the North Sea," creating "hit-and-miss" downpours across the UK.
The weather in the UK will be relatively stable this week, thanks to high pressure.
However, low pressure is forecast to bring an unpredictable period of weather in from the northwest towards the end of the week and into the weekend.
"Towards the end of the week and into the weekend, the jet stream dives south, bringing low pressure to our beaches," it continues.
Met Office told Express: "There will be low pressure to the west of the UK, so there will be some action - and that will be from Sunday and next week."
Individual forecasts indicated that showers will mostly begin on Saturday, with places like Portsmouth experiencing three days of rain.
Rain will fall in Manchester this weekend, but it will be light.
Low pressure systems in the west appear to be primarily affecting the south-west of the country, with Bath experiencing three days of continuous rain.
According to Met Office estimates, storms in the east could begin as early as Monday, September 5, in regions like Suffolk.
