Low cloud and spells of rain turn increasingly to sleet to snow during the evening as it becomes markedly colder and the easterly wind feels increasingly raw. Icy stretches and patchy snow accumulation are possible by dawn. Lows -3°C.
Bright but bitter, with icy surfaces possible as raw winds bring in scattered blustery snow showers throughout the day. Snow accumulation should be most significant on hills, with blizzards and drifting here. Highs at best 1°C, feeling more like -8°C.
Very cold initially, with some further blustery snow showers and raw easterly winds on Sunday.
Gradual improvement is likely by Monday: becoming more settled and a little milder but with overnight frosts remaining likely.
