Temperatures are expected to reach up to 18C (64.4F) with warm air and sunshine expected to sweep north from the continent. The change will offer a pleasant change from the turbulent weather Storm Katie brought over Easter last weekend.
Temperatures could reach 18C (64.4F) in London, and up to 17C (62.2F) in central and southern England on Sunday - putting them on a par with Barcelona and hotter than the Spanish capital Madrid, which is expected to see temperatures of 15C (59F). From Saturday, the UK will be able to feel the warmer weather, which will be around 5C higher than the English average for April, 11C.
Met Office forecaster Craig Snell said: “Warmer air will become widespread on Sunday and a lot of us will notice a slightly warmer feel, slightly muggier.
“It will be the first widespread warm spell we have seen this year.”
The warmer climate is due to tropical continental air being brought into the UK through a change in wind direction. Mr Snell said although the weather will be noticeably warmer, we can still expect some April showers, which will get heavier on Monday.
