The Met Office has issued a long-range forecast for between April 15 and 29, and experts warn of cold nights.

They said: "Weather patterns are most likely to remain fairly slow-moving through the second half of April.

"High pressure may remain centred to the north or northeast of the UK, potentially bringing more fine and dry weather.

"However, there may also be some interludes of rain or showers, these perhaps more likely to affect southern and western parts of the UK.

"Temperatures are likely to be around or a little above average overall, and feeling warm inland at times during the day, although some chilly nights are still possible under any clear skies."

Weather expert Jim Dale that, once we are out of this week, it'll "turn noticeably colder for a spell", with frosts "returning for many".

He added: "That's April for you!"
