Thunderstorms are set to hit the UK next week, bringing the sunny weekend to an abrupt end.
Today will see a mix of sunshine and showers as a weather front brings clouds to the south west of England and south Wales.
Heavier downpours with the potential to turn thundery are forecast later in the day in the Midlands and north of England.
Temperatures are set to get cooler, but could still reach a high of 18C in the south east, which is expected to stay dry and bright with 14 to 15C felt quite widely.
Next week is set to bring even more rain, as high pressure starts to build across the UK.
Showers and cloud are forecast in the east of England on Monday, particularly Yorkshire, Lincolnshire and East Anglia.
Other places will remain dry and sunny, however, this is set to change on Tuesday.
More thunder and rain is set to hit the south west of England, moving into Wales and potentially the south east.
Giving the outlook for the week ahead, BBC forecaster Darren Bett said: "For the most part, pressure is lowering in the south west so the winds will be strengthening and we'll see this band of rain mainly affecting the south west of England, pushing into south wales perhaps towards the south east of England.
"We'll certainly have stronger winds for England and Wales and for Northern Ireland and whilst many places will be dry, it will feel a little chillier in that wind because it's coming in from the east.
"But from mid-week towards the end of the week, with the winds becoming lighter, most places will be dry, with some sunshine, it should be turning warmer as well."
A Met Office spokesman added: "A chilly bright start for many on Sunday, always cloudy down towards the south west of England and Wales.
"During the day we will see sunny spells elsewhere but showers will also develop and these could be heavy at times through the afternoon.
"In those sunny spells though temperatures reaching the mid to high teens.
"As we head through the evening and overnight period cloud will continue to build from the south west making its way into the Midlands by the end of the night.
"Elsewhere showers will fade away and we will see further clear skies developing across northern parts of the UK.
"The outlook, sunny spells and scattered showers, although some wet weather is possible in the southwest on Tuesday."
