The UK is set to bask in temperatures peaking at 87F as a plume of heat makes its way to the country once more from the start of next week.
Following a dreary start to the month, the country will see a north-south divide as western Scotland continues to be drenched by torrential downpours while the rest of the UK enjoys spells of sunshine and dry weather.
The Met Office has issued a yellow rainfall warning for western Scotland where as much as 50mm of rain could fall in hilly areas.
However in stark contrast, bright and sunny spells are expected to make their return to the rest of the UK by Monday, with temperatures reaching 77F today before continuing to rise next week.

'We've already see more than 50mm of rain in some parts of western Scotland overnight and a further 50mm is possible through the day today so there is a yellow rainfall warning for parts of north west Scotland. Also quite breezy so quite a windy day as well.
