The Met Office said: "Friday is remaining unsettled with showers or longer spells of rain, along with further snow, mainly over hills. Showers locally heavy with hail and thunder. Sunny spells too. Breezy and staying cold.
"Saturday-Monday:"Sunshine and showers on Saturday. Rain and stronger winds will spread in from the northwest on Sunday, then will clear to blustery showers on Monday. It will become less cold."
