The Met Office has issued a heatwave warning from Friday to Sunday.
The spell of hot weather could end rather dramatically on Saturday with a 'Spanish Plume' which involves very warm and humid air moving up from the Spanish plateau to the UK.
If this meets cooler air from the Atlantic, the warm air can be forced rapidly upwards to produce thunderstorms.
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.
Nottingham GP Dr Ian Campbell talks about how to be prepared for the heatwave
