Brits are set for a mix of sunshine and showers with balmy 23C highs before temperatures tumble by the end of the working week.
It was hot and humid for many parts of the UK on Monday with most of the rain falling in central and northern England.
And on Tuesday the showers are likely to be further south with it being sunny for northern parts of the UK and into the evening that rain could get quite heavy.
Still it is set to continue to be unseasonably warm through the middle of the week with temperatures in the low to mid 20Cs and a high of 23C in the south.
But by Thursday and a high pressure system will have taken control meaning drier but cooler weather and it will be notably different with the mercury in the mid to high teens by the end of the week.
BBC weather forecaster Simon King said: “The rain that we did have on Monday, around central portions of the UK, you can see that from the clouds there earlier on, that is gradually moving further southwards.
“Sunny spells to the north and the south of that, but as we go through the next few days, well this high pressure will start to move its way in.
“Now during Tuesday we will see some rain across the far south of England just on this weather front. Showers just gradually getting a bit heavier as the day goes on and they will move in from the English Channel to affect south Wales through southern areas of England.
“Further north though it is looking dry on Tuesday, again there will be some sunny spells for many and again feeling quite fresh especially across Scotland, temperatures here around 15C or 16C.
“A fresher day for many across England and Wales except the far south where it could still feel quite warm and humid. Throughout Tuesday and night that rain could be quite heavy in some parts, there could be see surface water spray into the evening .”
Then by the end of the week it will feel a lot colder due to a low pressure coming in from Scandinavia, the high pressure out to the Atlantic and there will be a northly wind from the Arctic.
Fine for most. Rain in south Tuesday into Wednesday morning.
Most areas fine and dry with sunny spells. A few light showers for northern and western Scotland. Cloudier across southern UK with spells of rain, heavy at times. Light winds for much of east and central UK but breezy elsewhere.
Rain continuing in far south with some heavy bursts likely. Otherwise dry for many but still some light showers for northwestern parts. Another mild night in far south.
Rain in far south, some heavy at first, easing and clearing to the southeast. Otherwise mostly fine and dry though still some showers in northwest, heavier later for far north.
Outlook for Thursday to Saturday:
A good deal of dry weather with sunny or clear periods. Northern and eastern areas will see some showers and here it will be breezy. Rather cool everywhere.
