Brits are set to see temperatures ratchet up over the weekend by more than 10C in some parts and the mercury could hit 41C next Tuesday which would make it the UK's hottest day on record.
Extreme conditions are being predicted by the Met Office which has a yellow amber warning in place for heat that will run from Sunday until Tuesday.
People are being advised to take care under the oppressive weather and there is also anticipated to be an increased strain on hospital and train services.
