Heavy snow flurries are set to hit parts of the UK over the weekend, with treacherous icy conditions and rain also affecting thousands.
A dense pool of cold air over Scandinavia continues to exert a strong influence on the UK weather - so don't put your coats away just yet.
A yellow warning for ice is covering much of north-east England and large parts of Scotland until 6pm on Saturday - bringing dangerous conditions for motorists.
Heavy snow is forecast for large parts of Wales throughout Saturday, while small flurries could hit London and parts of south-east England, the Met Office said.
Torrential rain is forecast across Cornwall and much of Devon until 8pm on Saturday evening, bringing the risk of flooding and transport disruption.
Forecasters said 15-25mm of rain could fall widely, with 40-50mm possible across Dartmoor and near to the south coast.
As of 5am on Saturday, the Environment Agency had 69 flood warnings in place across England meaning immediate action is required, and 231 alerts, meaning flooding is possible.
There are also currently five flood alerts in place for Wales.
Nicola Maxey, a Met Office spokeswoman, said the downpours will be caused by a weather front moving in from the South West.
Ms Maxey said: "From Friday evening we've got a series of weather fronts bringing rain across Cornwall and much of Devon until tomorrow.
"As this rain starts to move north it will combine with cold air already over the UK, causing snow across much of Wales, where up to 20cm could fall in the highest regions.
"Over the weekend large swathes of the UK will see some form of snow, with warnings in place for much of Scotland and the north east of England.
"Even parts of London and the South East should see a small flurry, which is unlikely to settle."
It comes after parts of Scotland were blanketed by up to 19cm of snow in just 24 hours overnight on Thursday, while areas in south-west England recorded almost 30mm of rainfall.
Much of England and Wales will also see snowfall and widespread ice between Monday and Wednesday, with warnings over road closures, power cuts and risk of injury due to ice.
Forecasters added some rural communities could become "cut off" due to the wintry weather.
Ms Maxey said the weekend will also be very cold, with the highest temperatures only reaching 6C, along with frost on both mornings.
Met Office chief meteorologist Andy Page added: "The most likely areas for disruptive snow are across Wales and over the Cotswolds, where there is the risk of a few centimetres accumulating at lower elevations, but this could increase to 15cm or more at locations above 250m.
"Saturday night will see temperatures falling away from the far South West, with a widespread sharp frost likely across the rest of the UK."
Ms Maxey added: "As we move into next week another front will move in from the South West with long periods of snow and icy conditions for most of England, Wales and Scotland.
"Up to 5cm is expected off the coasts, which will reach highs of 15cm in the higher areas in Scotland and Wales."
She warned drivers to prepare cautiously for "dangerous" icy conditions, which could cause some disruption and potential injury.
Today:
After an icy start it will stay cold in the north with sunny spells and a few wintry showers. Rain and strong winds in south with some hill snow, especially over Wales, clearing south during the afternoon.
Tonight:
Very cold for many northern and central places with a widespread, locally severe, frost. Cloud slowly clearing in south with winds easing.
Sunday:
Cold and clear for many, though cloud increasing from west bringing another band of rain to the southwest.
Outlook for Monday to Wednesday:
Rain will spread across many areas, turning to snow across central and especially northern parts of England and southern Scotland. Remaining cold in the north, milder in the south.
