Cold weather will return to Britain this weekend with daytime temperatures struggling to get above 5C in much of England and sub-zero lows overnight.
The Met Office said northern Scotland will be the warmest part of the UK tomorrow with the mercury staying above average after nudging 16C (61F) on Tuesday.
But it will turn colder into the weekend with England and Wales expected to see temperatures around 3C to 6C below average on Saturday and Sunday.
It comes after the UK recorded its coldest January night since 2010 last weekend when temperatures plunged to -19C (-2F) in Scotland amid heavy snowfall.
Highs of just 3C (37F) to 5C (41F) are expected for most of England and Wales this Saturday, although the South West could see 8C (47F) and Scotland 9C (48F).
Temperatures on Saturday night are set to fall to -2C (28F) in the North of England while most of the rest of the country will drop to between 0C (32F) and 3C (37F).
Sunday will bring daytime highs of 3C (37F) to 6C (43F) for most of England, but the South West and Scotland will see 9C (48F) and Northern Ireland could hit 10C (50F).
Tonight will see rain in North West Scotland edging slowly south while cloud across southern England and Wales will spread north amid generally mild temperatures.
Downpours in Scotland will then ease tomorrow as conditions turn brighter but it will stay cloudy in South East England and begin to feel cooler for most places.
This weekend could bring wind and rain to the North West, while it will be mostly cloudy in central and southern England, and sometimes Wales with drizzle.
On Tuesday, Cassley in the Scottish Highlands reached 15.7C (60.3F), which was a new date record for the highest temperature on January 14 since records began.
That also made Tuesday the UK’s warmest day of 2024 so far – beating the previous high of 14.2C (57.6F) set at Merryfield in Somerset on Sunday, January 5.
Altnaharra in the Highlands plunged to -18.9C (-2F) on Saturday, January 11 – which was the coldest January overnight temperature since 2010.
Much of the UK endured sub-freezing temperatures last weekend, dropping to -11.2C (11.8F) at Shap in Cumbria while Bala in Wales recording -6.7C (19.9F).
The UK Health Security Agency had a cold weather health alert in place for all of England during what became a prolonged chilly spell at the start of the year.
But the sudden change in conditions this week resulted in a 34.6C (62.3F) swing in temperatures in just three days in northern Scotland, between Saturday and Tuesday.
The average low in northern Scotland for this time of year is -0.3C (31.5F), while for England, overnight lows are about 1.5C (34.7F).
The Met Office had a yellow alert for fog in force for much of England until 11am today with forecasters warning the weather could cause travel delays.
Some of the UK’s busiest airports saw disruption around Christmas time as thick fog blanketed the country, with delays at Heathrow, Luton and Manchester airports.
Flights were also disrupted earlier this month as snow, ice and heavy winds prompted runway closures or pauses to operations at Manchester, Birmingham and Bristol.
