Farmers Weather expert Garry Nicholson has predicted continued milder weather for the upcoming week, with heavy and persistent rain in Scotland and south-west England.
The country has seen increasingly mild temperatures over the past few days, with some places recording highs of 16 to 17C.
But Farmers Weather expert Garry Nicholson said double-digit temperatures in December were not unusual.
Temperatures through the weekend and early next week are expected to remain mild, with heavy rain and some fog patches.
Mr Nicolson said: “A slow moving frontal system affects southern and central Britain during Saturday, bringing some persistent rain, heaviest toward the south-west.
“The high ground of south-west England and perhaps south Wales could see an inch of rain - around 20-30mm.
“A few hours of heavy rain will advance across south-eastern regions on Saturday evening but will clear overnight.
“Sunday will be a much brighter day for most places, with sunshine breaking through for much of England and Wales, although central and south-western areas may start with fog patches."
“Next week brings some further rain at times to western Britain, where it will be often rather murky,” Mr Nicholson added. “Some rain will reach eastern districts, but amounts should be fairly small to the east of high ground.
“Temperatures will stay fairly mild, between 8 and 12C for several days ahead. Locally it may dip below 5C on some nights, but most places will avoid a frost for many nights ahead."
