Police forces across the country have been slammed for threatening snowball fighters with £200 fines as an Arctic ice blast brought six inches of the white stuff to the UK today.
Forces in Wiltshire and Surrey sent out warnings urging families not to break lockdown when frolicking in the snow, saying 'Covid regulations still apply' and social distancing must be maintained.
Their warnings will be especially disheartening for Britons keen to venture out into a snow-covered wonderland for a second day running as a further three inches of snow is set to fall overnight.
The Met Office said the mercury could dip between minus 4C (24.8F) and minus 6C (21.2F) going into Monday - with parts of the Midlands told to brace for minus 10C (14F).
An amber weather warning for snow is in place covering an area from Nottingham to Stoke-on-Trent, meaning travel disruption and power cuts are likely.
In a bid to deter any potential lockdown rule breakers, Surrey Police tweeted: 'We are currently receiving lots of calls and reports relating to snowballs being thrown and people outside sledging.
'Enjoy the snow today but please don't involve other people, particularly more vulnerable residents. Please stay safe and remember that covid regulations do still apply.'
Wiltshire Police inspector Louis McCoy wrote: 'I don't want to be dealing with sledgers and snowball fights. There's still a lockdown on. Think about it, don't be tempted.'
Kingston Police in west London urged revellers to enjoy the snow 'from the comfort of your own home' as 'there's a pandemic going on'.
Police in the London borough of Merton comically added: 'Sorry to be "that grumpy relative" but with the snow coming down the way it is, please drive carefully.
'And if you’re going to have a snowball fight, please stick to your bubbles. Also do not eat yellow snow.'
But their warnings did not dishearten revellers who took full advantage of the snowy weather today, flocking to frolic and build snowmen, with a snowball fight even breaking out outside Buckingham Palace.

By mid-morning on Sunday, the flakes were falling thick and fast in London and elsewhere, with the Met Office saying that up to six inches could fall by the end of the day.
And tomorrow will only get worse, with parts of the Midlands potentially recording 15cm (6in) of snowfall by the end of the day, with the snow expected to remain on the ground well into next week.
Meteorologist Simon Partridge said: 'The band of snow that came through overnight stalled over the Midlands and will then track its way back over south-east England.'
He added: 'Our main focus is that it is going to be a really cold night, particularly across central and southern parts of the UK - so the whole of Northern Ireland, all of Wales, most of the southern half of England from the Midlands and southwards.'
Mr Partridge added: 'Temperatures are expected to dip to between minus 4C (24.8F) and minus 6C (21.2F) quite widely tonight and where we get that snow lying in parts of the Midlands we could see one or two places where temperatures are as low as minus 10C (14F).'
Even in areas with lighter snowfall, a widespread frost is forecast, and conditions are expected to be hazardous including spots of ice on the roads.
However, it wasn't all fun and games, with several road accidents being reported amid the adverse weather.
One video shot on Hatter's Lane in High Wycombe showed a black Mercedes knocking a parked car off the road as it appeared to slide into the path of another vehicle before careering into a second and third parked car.
Seconds before the collision on the snowy street, people can be heard saying that they'd decided to wait and see if the weather improved before risking the snow downhill road.
The Mercedes then appears to continue down the street, despite the trail of destruction.
Residents in Hampshire got a shock when they were awoken by a 'thundersnow' strike.
According to the Met Office 'when thunderstorms form in wintry conditions, they can sometimes give rise to heavy downpours of snow which are often called 'thundersnow'.
'Thundersnow is unusual only because it can only occur in a few months of the year.'
Reacting to the strike, one person near Portsmouth posted: 'So this just woke up the whole village with a jump. Anyone else?'
Another said: 'Man alive! That sure woke me up.'
A third wrote: 'Woken up by thundersnow?. It takes a lot to wake me but was that loud.'
Though the strike wasn't heard in other places in the UK, photos showed the snow spreading across the country, with even the capital getting a dusting.

The weather caused the closure of four vaccination centres in South Wales, which Cwm Taf Morgannwg University Health Board said were shuttered for 'safety reasons'.
Sky News reported that the board said those with appointments at the centres in Bridgend, the Rhondda, Abercynon and Merthyr Tydfil had been contacted to bring their time forward or reschedule their jab.
Meanwhile, an FA Women's Super League football match between Chelsea and Bristol City was cancelled after the latter said their pitch was 'unplayable'.

Heavy snow and ice also led to a crop of crashes on the roads this morning, including a gritter lorry that overturned near the village of Holne on Dartmoor in Devon and blocked the road.
Another lorry jack-knifed in an accident in Norfolk. The vehicle skidded out of control and ended up sideways across the A148 at Hillington, near King's Lynn. Luckily, it didn't hit any other traffic and the driver escaped shaken but unhurt.
Two people had to be cut out of their car with hydraulic rescue equipment by firefighters in Kent. Their vehicle collided with a tree in the early hours of Sunday amid wintry conditions, leaving the driver and their injured passenger trapped in the freezing cold, police said.
Meanwhile in Leicester, police said a five-car accident had closed part of the M1 at junction 22.
Highways England warned that the snow had caused collisions on the M3, M27 and M25. The agency urged drivers to only travel if absolutely necessary.
The public were warned to expect some icy patches on untreated roads and pavements, with journeys by road and rail likely to be affected. A similar warning is in place along the east coast of Scotland and covering most of the island of Ireland.
The showers of sleet and snow are expected to die down, with a heavy frost due to set in across most parts of the country on Sunday evening. The wintry showers will continue in north and western parts of the UK.
The Met Office said disruptions caused by snow were likely to continue throughout Sunday. It said in a Twitter post: 'Outbreaks of snow will continue over parts of north Wales, the Midlands, East Anglia and south-east England with some further significant accumulations causing disruption.
Despite government pleas to stay indoors, crowds of people flocked to the capital's parks to take advantage of the snow

'Wintry showers will also affect western parts with local temporary accumulations and a risk of ice.'
This morning's travel chaos comes after the effects of a storm last week continued to cause havoc yesterday.
Temporary barriers along the River Severn in Worcestershire were breached, with residents describing the surging floodwaters as a 'tidal wave'.
Defences at the riverside town of Bewdley failed, leaving homes and businesses under water and residents devastated.
Irene Buxton, 70, who lives near the defences, said she was woken by a 'crash' as the barriers collapsed on Friday night.
'I looked out of the window and it was like a tidal wave going towards the town,' she said.
'The water is in my hall and in my kitchen and we're just battling to keep it out of the living room.'
Hereford and Worcester rescue teams were out in force, rescuing a man and his two dogs from Bewdley's floodwaters, which were expected to peak at 5.53m, just shy of the November 2000 record of 5.56m.
Further warnings were issued along a stretch of the Severn, including Ironbridge in Shropshire and Stourport-on-Severn in Worcestershire, which saw severe flooding during Storm Dennis last year.

Environment Secretary George Eustice warned of more 'challenges' in parts of England ahead of the predicted snowfall.
The Met Office said a band of rain will cross the South West of England and turn to snow as it moves eastwards. Up to 2in of snow could settle, but areas above 300ft could see as much as 10in.
Temperatures across the whole of the UK dropped below freezing last night, with the coldest temperatures in the Scottish Highlands at an icy -10C.
Elsewhere, London and Manchester got down to -3C overnight and Bristol, Belfast and Glasgow dropped to -2C.
Frosts are expected overnight on Monday and Tuesday.
Martin Bowles, meteorologist at the Met Office, said: 'The biggest hazard over the next couple of days is going to be ice because we're getting these snow showers which will all freeze overnight.

'Obviously roads tend to be quite well gritted, especially main roads, but I would warn people to be careful on pavements, minor roads that don't get gritted or city roads,' Met Office meteorologist Martin Bowles said.
The Met Office's first warning for snow and ice is already in place in north-west England, but four more will be in place by tomorrow morning.
Areas being placed under warnings are Northern Ireland, south-west England and South Wales, the Midlands, and south-east England.
Mr Bowles said the cold spell would continue until about Wednesday before being replaced with milder temperatures in the final days of the month.
'That's not to say that that's the end of all cold weather for winter, it isn't, we've just got a mild spell coming up,' he said.
Despite people being urged to heed flood warnings into the weekend, Mr Bowles said they were 'gradually reducing' and that more heavy rain was not expected until Wednesday night or Thursday.
'We're hopeful that the river levels will fall quite significantly before that so we're not expecting any significant flooding problems over the next few days, apart from in areas where the warnings are already in place,' he said.
The Environment Agency previously warned of 'exceptionally high river levels' following days of heavy rainfall in the wake of Storm Christoph, with hundreds of properties across the country flooded.
