Wales snow: Icy conditions forecast for the weekend
BBC meteorologist Derek Brockway said snow in the north and east would gradually ease off through Friday night.
Elsewhere it will be drier and breezy with a widespread frost, and ice will be a hazard with lying snow and slush freezing as temperatures drop.
Saturday will be mostly cloudy with further snow in places, most of it in the east and north-east.
On Sunday there may be a little more snow in the east and north-east.
