The UK can look forward to sunny weather for the rest of this week – but the pleasant daytime conditions will be followed up in some parts by sub-zero temperatures once night falls.
Forecasters at the Met Office have predicted daytime temperatures of up to 17C (63F) in London and 10C (50F) in Edinburgh on Tuesday before the mercury drops on Wednesday, with chilly nights throughout the week.
But the daytime temperatures should rise again in time for the weekend – and meteorologist Steven Keates has said it should stay "predominantly dry" for much of the country.
Mr Keates, from the Met Office, said: "Apart from a bit of a blip for parts of the UK from Tuesday, we’ll see the sunshine sticking around for the rest of the week.
"Rain over Northern Ireland and the west of Scotland will move further southeast on Monday night and through Tuesday – this is a weakening feature though, so there won’t be a huge amount of rain.
"It just means a bit of a cloudier outlook for the northern half of the UK on Tuesday, and for the south on Wednesday."
When the sun is shining, the Met Office has said levels of UV in the UK this week could be as strong as they would normally be in late August.
It follows what has been the coldest start to April since 2013.
The Met Office said average temperatures from 1 April to 18 April were 2-4C cooler than average for that time of year.
Mr Keates said the forecast for the end of April is unclear, and could bring more unexpected weather.
