BRITS are to bathe in warm temperatures as high as 25C this weekend before cooler Autumnal weather sweeps in.
Parts of the country may see high temperatures over the coming days as an Indian summer is predicted.
The Met Office has said London and the South East could see maximum temperatures of 25C tomorrow, with both days having bright and sunny spells.
Sunday will be slightly cloudier but the temperature will otherwise remain about 23C in most places.
The western parts of England and the whole of Wales could see some clouds and potential rain tomorrow morning before it brightens up in the afternoon with highs of 21C.
This could take a turn on Sunday with some heavy showers in the South East.
North-western Scotland meanwhile will be windy tomorrow morning before becoming a mainly dry day with some bright or sunny spells developing and highs of 21C.
Sunday will be largely dry and bright with strong southerly winds around the coast.
The weather will take a turn on Monday, with the Met Office predicting next week to be the start of autumnal weather.
It comes as people have been warned by the AA to not top up their cars "outside of their normal routines" ahead of planning any potential weekend trips away to take advantage of the weather.
Nicky Maxey, for the Met Office, said: "You're much more likely to see highs of 23 degrees more widely but we could see some spots reaching highs of 24 or 25C.
"It will be similar on Sunday, with places such as Lincolnshire potentially seeing similar temperatures, but still the higher temperatures being in isolated pockets rather than widespread."
Mr Maxey added: "Sunday perhaps will see an increased chance of rain, but there's still plenty of sunny spells around and fine weather.
"But we have got a cold front moving in to Northern Ireland and Scotland on Sunday and then crossing from east to west of the UK on Monday.
"That's bringing some potentially heavy rain.
"There's still some sunshine scattered round on Monday but we could see heavier showers."
The early autumn sunshine will continue for many over the next few days, but a change is on the way.

Monday will see a shift in our weather, with an active weather front bringing heavy rain and blustery winds as it pushes in from the west across the UK.
Expert Met Office Meteorologist, Adam Thornhill, said: "For the rest of this week and for the weekend, we will continue to see low-pressure systems bringing blustery weather to the north of the UK whereas further south the drier, warmer weather remains thanks to the influence of high pressure extending up from the Azores.
"However, a shift in the position of the jet stream brings a change in our weather next week, allowing a cold front associated with a low-pressure system in the North Atlantic to spread eastwards bringing wet and windy conditions across the whole country throughout Monday.
"Behind the cold front, conditions will feel much more autumnal with a cooler feel and blustery showers for many."
