After another wet and windy weekend ahead, colder conditions will move in across the UK.
A cooler pool of air with a northerly flow will develop in the north of the UK through Saturday evening.
By Sunday most of the UK will be in the northerly airflow, with lower temperatures spreading further south overnight.
Showers will fall increasingly as sleet and snow in the north, even to lower levels.
Some showers further South and West, and perhaps a more persistent spell of rain overnight into Monday, could also turn to sleet and snow mainly over high ground such as the Brecon Beacons, Exmoor and Dartmoor.
Overnight frost will become more widespread by Monday night, with overnight temperatures below 0°C across much of the UK.
Temperatures could get down to -10°C in sheltered glens, or across high ground areas of Scotland where there is lying snow.
Deputy Chief Meteorologist, Helen Caughey, said: “After a spell of wet and mild weather to start 2023, a brief cold spell will change the feel of our weather across the UK for a few days next week.
“As a northerly flow establishes, we’ll see temperatures decline with overnight frosts returning and the chance of wintry showers in the north.
“It will certainly feel cold in all regions too, with the northerly winds creating a notable windchill.”
The colder spell is expected to be short lived, with milder air moving in from the Atlantic bringing wet and windy conditions back to the UK towards the end of the week.
There is a chance of some transient snow on the leading edge of the frontal rain as it moves through however the detail on this is currently uncertain.
