Monday is set to be much colder and drier than recent days, bringing frost on Tuesday morning.
On Tuesday, the Met Office says a cold damp weather system is set to move in from the west, making conditions more changeable.
May Day bank holiday weekend is set to be a disappointment for many hoping for a repeat of Easter’s heatwave.
That four-day weekend saw record-breaking temperatures in many parts of Britain, with 25C in parts of the southeast.
“Clear skies at night will mean temperatures should drop and there will be a touch of ground frost overnight to Tuesday”
Alex Burkill, Met Office meteorologist
Met Office meteorologist Alex Burkill said: “There will be a chilly start on Monday but with some fine and sunny weather to come.
“Temperatures to warm up quite nicely with central parts of Scotland having clear skies allowing for some frost at first.”
He also warned about low and thick clouds moving over much of the country from Tuesday, indicating rain is on the way.
Alex added: “There will be some patches of mist and fog across eastern parts of England.
“And high chances of mist and fog in the east that will gradually clear and we will see the cloud bubbling up a little bit across many places.
“As we go through Monday afternoon, there will still be some bright and sunny weather.”
While temperatures on Monday and into Tuesday morning could reach the high teens and even 20C in places, this sadly won’t last.
Alex went on: “Clear skies at night will mean temperatures should drop and there will be a touch of ground frost overnight to Tuesday.
“Wet weather will push across Northern Ireland as we go through the night.
“There will be a bit of rain at times as we go further into the week.
“Temperatures may turn a little bit cooler as we head towards that long bank holiday weekend.”
It comes after Daily Star Online warned the May Bank Holiday could be a three-day washout.
