Temperatures are set to surge as high as 24C in London later this week, making the capital hotter than Barcelona, according to the Met Office.
The blustery conditions of Storm Dave are forecast to be replaced by sunshine and warm weather with temperatures set to reach 24C in London and 20C in Manchester on Wednesday.
Highs of 24C would be enough to surpass the hottest day of the year so far, which was 20.9C in Gogerddan near Aberystwyth on 18 March.
It will also mean many parts of the UK will be hotter than Barcelona which is set to reach 19C on Tuesday and Wednesday this week.
Tuesday will also be sunny in the UK with temperatures reaching 20C in London and 19C in Glasgow.
However the warm weather is not set to last as the Met Office has forecast temperatures to only reach 14C in London on Thursday, with most of the UK seeing the mercury drop below 10C.
It comes after Storm Dave brought snow and strong winds over Easter weekend, causing travel chaos and leaving homes without power as it swept across northern parts of the UK.
Gusts reached 93mph at Capel Curig in North Wales, while winds of 75mph were recorded at Emley Moor in West Yorkshire and St Bees Head in Cumbria, and one of 73mph was recorded at Buchan in Aberdeenshire, the Met Office said.
Some properties in Scotland were left without power following the high winds overnight. Scottish and Southern Electricity Networks (SSEN) fault response teams were out on the network working to reconnect the small number of customers affected, mainly in Skye, Caithness and coastal parts of Aberdeenshire.
