The unseasonably cold weather in southern areas and the Midlands will make way for a dry and sunny Bank Holiday weekend, forecasters said.
A chilly weather system has sent temperatures plummeting far below what they should be this time of year - but the May sunshine is set to return for the three-day break.
John Lee, a forecaster for MeteoGroup, the weather division of the Press Association said: "We have got a low pressure system, which is spreading from the North Sea.
"It's directly over the East Midlands, and heading towards London and the South East.
"That's what's bringing these showery outbreaks of rain and keeping the skies pretty cloudy.
"It's also got some quite brisk winds, so all of those areas in the South and South East are feeling quite chilly."
The forecaster said temperatures were "quite remarkably colder" than the average highs of 17C (63F) for this time of year.
At Stansted Airport, it was a chilly 6C (43F) at midday, while in central London it was 8C (46F).
But it is not miserable for the whole country - in the North and North West it has been a "considerably nicer day".
"Scotland is at about 13C (55F), which is probably the mildest place today," Mr Lee said.
The outlook is much better for the coming days, with the North Sea system heading further south.
Mr Lee said: "Tomorrow will be a dry day for many areas, with lots of sunshine, with just an outside chance of showers.
"Many areas will feel warmer as well tomorrow.
"It's a repeat situation on Sunday, with more sunshine and feeling slightly warmer."
The weather will take a slight downward turn for Monday, with rain spreading into Scotland, Northern Ireland, and the western half of Britain.
Mr Lee added: "The best places for some dry and sunny weather on Monday will be the South East."
