Britain has basked in days of sunshine and blue skies this week as hot air from Morocco sent temperatures surging above 20C.
The mercury reached an astonishing 21.2C (70.2F) at Kew Gardens in London on Tuesday, the hottest ever winter temperatures ever recorded.
The Met Office said temperatures as high as 20C (68F) could be recorded in the capital on Wednesday as Britain enjoys another day of “wall-to-wall sunshine”.
But from Thursday, showers and milder weather are set to return, ending the record-breaking period of unseasonable weather.
Some snow could even fall over higher ground at the weekend, though conditions will be a far cry from the “Beast from the East” that froze Britain this time last year.
“Next weekend will bring a colder theme, and there is a chance of some snow to parts of the north and western Britain,” Exacta Weather forecaster James Madden said.
“The unsettled weather and snow will also be accompanied by some rather strong winds, gusts in excess of 70-80 mph are to be expected from next weekend onwards.”
Latest weather forecast models suggest snow will fall from Sunday night until Monday morning in parts of the UK.

Forecasts indicate a light dusting could impact some areas in Scotland, Wales and north-west England.
John Hammond, forecaster for Weathertrending, said the start of spring looks “a good deal chillier” than the end of February.
He said: “Early March may bring a shock to the system, with a turbulent, even stormy, few days from March 4.“The start of spring looks a good deal chillier than the end of February.”
The Met Office said the change will “take hold” by mid-week when temperatures are expected to reduce markedly from the 20C high recorded on Monday and Tuesday.
Met Office forecaster Dean Hall said: “A stark change is ahead, with later in the week seeing rain and strong winds risking gales of over 50mph.
“The theme of Atlantic systems bringing wet and windy spells looks to remain.”
The warmth follows last February’s “Beast from the East”, which plunged temperatures below freezing and brought heavy snowfall across the country.
Experts said climate change is heating up the whole weather system and making extremes more likely.
Cooler temperatures expected from Wednesday onwards will be “still above average” for February, the Met Office said.
Heavy showers are possible on Thursday as temperatures struggle to get above 11C (51.8F) or 12C (53.6F).
