High pressure brings another chilly start to the day on Sunday with a risk of a ground frost. A mostly fair day with good sunny spells, although some patchy rain may affect northern Scotland. Through the morning there may be some showers around for southern Scotland and northern England which will edge south through the afternoon. Some heavier bursts are possible in and around the Yorkshire Dales and the Peak District. High temperatures widely at 8 to 11C, though 12 or 13C is possible in the west of Ireland.
A band of rain will continue to edge southwestward across Scotland overnight with showers following behind to the northeast. Ahead of this, over southern Scotland, Northern Ireland, England and Wales there will be a mixture of clear skies and broken cloud. Thicker cloud cover for Ireland. Overnight lows falling to -1 to 3C. Slightly milder in the southeast.
High pressure to the southwest and low pressure to the northeast keeps the UK into a chilly northerly airflow on Monday. The day will start cool with a touch of frost for many. There will be good spells of sunshine and scattered showers for Northern Ireland and Scotland, although a weak front could bring more persistent spells of rain to southern Scotland, northern England and into the East Midlands. To the south of this it should stay mostly dry with a mixture of broken cloud and some sunny spells. Highs widely at 8 to 11C again, though 13 or 14C is possible in southeast England and western Ireland.
Tuesday will be a mixed day of cloudy skies, sunny spells and showers, some of which may be rather wintry, with low pressure to the northeast and southwest. Showers may merge to give longer spells of rain over Ireland and northern and central parts of England. Wintry showers are likely to be confined to higher ground in Scotland. The best of the brightness in the northeast, becoming cloudier through the day in the southwest. Highs at 8 to 13C.
