Sunday
Low pressure to the north on Sunday with a cooler, westerly flow affecting all areas. Sunshine and showers for most to start, showers most frequent to the west and turning to snow over higher ground. A deep area of low pressure looks to develop west of Ireland through the morning bringing strong gales and heavy outbreaks of rain to Northern Ireland, Ireland, Wales and southwest England later. High temperatures at 4 to 10C.

Sunday Night
Heavy showers generally clear to the southeast through the night though showers persist over much of Scotland and for eastern coasts of England too. Gales spread east across the whole country although winds do start to ease to the west. Variable amounts of cloud around for western areas staying cloudier to the east. Away from the Highlands of Scotland, overnight lows generally staying above freezing at 3 to 7C.

Monday
Low pressure is to the east on Monday with a ridge to the west. The resulting northerly flow brings colder weather to all. Gales persist over eastern coasts for a time while early rain clears quickly to the south. Isolated showers may affect northern and eastern coasts, these wintry in places. Drier to the west with good spells of sunshine. A cold day at 3 to 9C.
 

Tuesday
Wet and very windy as fronts pass east through the country. There could briefly be snow over the high ground of Scotland. Turning milder for a time. Brighter conditions follow later to the west with frequent showers for coastal areas. High temperatures at 9 to 13C for most areas, 7 or 8C for western Ireland.
