Britons basked in the sunshine as temperatures soared to the highest level of the year today. Temperatures peaked at 29.1C (84.4F) in London, while much of Scotland, Wales and Northern Ireland also saw highs of 20 to 27C.
Forecasters have warned tomorrow could get hotter as an Iberian weather pattern is expected to descend overnight.
Met Office forecaster Dan Williams said: "We would expect to get into the early 30Cs tomorrow so this is likely to be a short-lived record."
Viewers have posted dramatic pictures of the storms which ravaged the UK last night. The photos were posted on the ITV News Facebook page.
It seems thousands of people were woken up by loud claps of thunder, seemingly constant flashes of lightning and torrential rain.
Britain is set to bask in the sunshine in the next few days with health officials issuing guidance on how to stay safe in the sunshine.
