Temperatures are set to soar to 26C as summer returns in time for the weekend.
Temperatures are expected to reach between 21C and 24C across parts of England and Wales with London expected to reach 26C.
It will be dry and sunny for many, although it will be cooler with more cloud in western Scotland.
While the next couple of days will become increasingly warm, the Met Office says there will be some chilly nights.
Much of the middle of September is forecast to be widely settled and dry with light winds and plenty of sunshine, especially in the south of the country.
However, there could still be some windier weather and outbreaks of rain in the North, particularly for northern Scotland.
