18 January 2013 Last updated at 20:00 GMT
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.
