Brits are set for a mini heatwave from today as temperatures hit 18C across parts of the country,
The Met Office states there will be some frost and fog early on Monday morning, but the skies will clear and temperatures are set to rise.
Patchy rain is expected in north west Scotland and parts of Northern Ireland, and there is a small chance of rain in the south-east.
But no showers are expected in other parts of the country.
Temperatures are expected to rise even further towards the end of the week meaning it could possibly become the hottest week of the year so far.
A Met Office forecaster said: "For the vast majority, once any early morning fog's cleared, it's looking like another dry day.
"Plenty of sunshine as well and really much warmer I think, with highs of 17C or 18C expected for many inland areas."
Clear skies and dry conditions are due to continue into the evening.
More warm, sunny weather is expected this week, as millions look ahead to another week of eating and drinking outside pubs, after lockdown restrictions were eased on Monday, April 12.
Met Office forecaster Marco Petagna said: “Daytime temperatures will rise a little over the next few days.”
An estimated 2.7 million people enjoyed drinks outside boozers this weekend, with around 250,000 venues now serving alcohol, while 20 million descended on high streets.
Around four million pints were drank per day and a whopping £3 billion was spent over the weekend.
Last year, the UK saw the sunniest April on record, according to the Met Office.
It was also the fifth warmest April on record and the UK only received 40 per cent of average April rainfall.
Fog and low cloud over eastern England will clear through the morning, although some cloud may linger along the coast. Cloudy in the north west with some rain, but elsewhere, there will be sunny spells and just a small chance of a shower in south-east England.
Low cloud and fog to clear in the morning, with dry with sunny spells across central and southern UK. Warm by afternoon. Rain in north edging south and easing, sunny spells and showers following.
Outlook for Wednesday to Friday:
Mostly fine and dry with sunny or clear spells and mainly light winds. Temperatures a little below average with overnight frosts. Becoming breezy in the south west.
