Wales weather: Snow forecast as temperatures plummet
Some weather forecasters are predicting up to 10cm (4in) of snow on higher ground in Wales this weekend after temperatures dropped to -8C (18F) on Friday.
Snow will fall on the hills and lower levels inland, the European Centre for Medium-Range Weather Forecasts said.
A Met Office yellow weather warning for snow and ice is place until Saturday morning along the UK's east coast.
Temperatures could drop to -10C (14F).
There could be 1-5cm (0.4-2in) of snow generally across Wales from the south Wales valleys northwards into Powys, the European forecaster said.
BBC Wales weather presenter Sabrina Lee said areas "inland areas over higher ground" were most likely to see the white stuff.
But she said not all forecasters were predicting very little snow for Wales.
"It's very tricky snow because a slight difference in temperature can make all the difference."
Two weather systems were expected over the weekend, each bringing cold air to Wales from the east.
"The first is from Saturday afternoon through until the early hours of Sunday morning and the second system on Sunday night," she said.
