A cold night for many with clear spells producing a widespread frost. Cloudier at the coasts where temperatures are unlikely to drop as low. Winds picking up around Anglesey where the odd shower is possible during the evening. Minimum temperature -1 °C.

Saturday:

Saturday will dry for most with the odd shower in the northwest. Temperatures recover slightly but stay largely below average. Later on, winds pick up along coasts and over hills. Maximum temperature 7 °C.

Outlook for Sunday to Tuesday:

Wet and blustery on Sunday, then a calmer, drier interlude early Monday before more rain arrives in the afternoon and winds pick up again. Temperatures dropping through the period.

A changeable and often rather unsettled period looks most likely. Further areas low pressure will move in from the Atlantic and whilst all parts are likely to see some rain at times, it is southern areas which may turn out to be wettest, relative to average conditions, through this period. Strong winds are also possible from time to time. Incursions of milder air are likely towards the south, but it could remain on the cold side overall further to the north, where there is potential for sharp overnight frosts where clear skies and light winds combine. By the latter part of this period, weather patterns in the vicinity of the UK may become rather more slowly evolving.

Low pressure is signalled become slow moving to the west then south of the UK, whilst pressure builds to the north of the country. Further rain is probable across southern and perhaps central areas, but below average precipitation could occur in parts of the north, especially the northwest. With a blocked weather pattern signalled to develop, this increases the chance of colder conditions overall, with associated winter hazards, e.g. snow and ice, occurring; this most likely further to the north.
