Forecasters warn of more snow in Wales but clearing
Snow and sub-zero temperatures are expected to make a short-lived return to Wales overnight.
Forecasters predict a band of rain, sleet and snow will push up from south Wales after midnight on Thursday.
The Met Office warns of between 8 and 12cm (3-5in) in some areas, with snow heaviest in Powys and north of the M4.
Temperatures in many areas will fall close to freezing or below and many will wake up to snow or frost although it is expected to be only temporary.
Fresh supplies of salt are being delivered across south Wales ahead of the next wave of wintry weather.
A ship arrived at Newport's South Dock earlier this week with 12,000 tonnes of salt from north Africa.
BBC Wales weather forecaster Derek Brockway said: "We're watching a deep area of low pressure currently out over the Atlantic. This will move towards Britain on Friday pushing a front northwards bringing a mixture of rain, sleet and snow.
"Most of Wales can expect a brief spell of snow but not everywhere, with probably very little in Cardiff, Newport and Swansea.
"Most of the snow will be north of the M4, with 2-5cm (1-2 ins) likely, and 10cm (4 ins) on higher ground. So there is a risk of some disruption in places for a time
"But the snow won't lie for long with rain and rising temperatures. Tomorrow night will be less cold with heavy rain washing away any snow."
He said Friday night would turn less cold with some heavy rain in places, with the forecast for next week milder, but wet and windy weather at times.
The weekend forecast is for patchy cloud with occasional showers and dry spells with blustery winds that will ease later on Sunday.
Temperatures will remain cold until at least Monday.
