Forecasters are predicting snow in parts of the UK this week as the Easter weekend's warm spell comes to an abrupt end.
Brits have flocked to parks, beaches and beauty spots over the last couple of days to soak up the rays, but this week could see heavy rain turning into snow or sleet over higher ground.
A yellow warning for wind is in place from 3pm tomorrow until 6am on Wednesday across the South West, Wales, the Lake District, the east coast of Northern Ireland and Dumfries and Galloway in Scotland.
Gusts could exceed 60mph. The weather warning will remain in place in the South West and parts of South Wales until midnight on Wednesday.
Although the winds are set to bring the most disruption, there's also a chance of snow in parts of northern England, as well as over the tops of the Scottish and Welsh mountains.
Met Office meteorologist Greg Dewhurst told the Mirror: "Today we may see a bit of wet snow over the tops of the Scottish mountains.
"Tomorrow a band of rain pushes into the south. It should stay as rain generally, but as it bumps into colder air across Scotland through the end of tomorrow, and into the early hours of Wednesday, we could see some snow over the tops of the Scottish mountains.
"Showers follow behind the rain on Tuesday evening and overnight into Wednesday. There could be some sleet and snow on higher ground in northern England and over the Welsh mountains.
"Elsewhere, on the lower levels, particularly as we go into Wednesday and even today, showers will be heavy and we could see some hail.
"But most likely the disruption will be from the strength of the winds and the risk of some heavy rain."
His forecast comes after Exacta Weather's James Madden predicted snowfall tomorrow and Wednesday for parts of Ireland, southwest England, Wales, the Midlands and northern England.
He said: "From around Tuesday of next week and into Wednesday will see things turning significantly colder for a small number of days.
"This period will also see rain turning to sleet and snow on Tuesday in places, before a well-organised band of precipitation turns to snow throughout the early hours of Wednesday morning.
"The good news is that some much warmer incursions of weather should start to push in across our shores regularly from around mid-month and into the final third of April, and this is also likely to continue well into May."
Temperatures on Easter Sunday had been expected to top this year's record of 17.8C but instead fell just half a degree short.
The mercury rose to 17.3C in Chertsey, Surrey - just shy of this year's record of 17.8C which was recorded in Santon Downham, Suffolk, on March 30.
Despite this the UK was still hotter than Rome, where temperatures reached 16C, for a second day in a row.
A band of rain drifting across the Irish Sea is expected to bring blustery showers to the west coast across much of the UK today, with a risk of hail and thunderstorms in places.
However wet weather is likely to be interrupted by sunny spells for many.
Temperatures are unlikely to climb above 15C on Monday and will be even cooler on Tuesday and Wednesday when they are not set to top 13C.
The Met Office's Honor Criswick said: "We were thinking this morning we would potentially get the warmest day of the year so far but we have not reached that.
"Today for most of us it has been quite a dry and bright day with sunny spells. It will generally feel cooler tomorrow.
"We do have a system out to the west bringing spells of wet weather which are currently in Northern Ireland and are just about to creep into the Western Isles.
"As that starts to move through cloud will thicken up from the west and that will spread eastwards.
"On Monday morning most of the rain will be across the South and South East and behind it there are going to be sunny spells and blustery showers.
"On Tuesday we do have quite a deep area of low pressure moving in bringing further rain in from the South West. We could see some heavy downpours.
"It will remain fairly unsettled later in the week but on Thursday it looks like the winds will begin to de-escalate."
