Clear spells this evening, but cloud thickening from the west overnight, bringing scattered showers. Though temperatures will be higher than previous nights, a touch of frost is still likely. Minimum temperature 0 °C.

Sunday:

Some bright spells on Sunday, but also rain and showers which may be heavy, thundery, and frequent at times. Feeling chilly and unpleasant in the wet and increasingly blustery conditions. Maximum temperature 11 °C.

Outlook for Monday to Wednesday:

Cold and bright on Monday morning, perhaps with a wintry shower. Rain arriving later, with hill snow overnight. Less chilly but showery on Tuesday and Wednesday. Colder air returning later.

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.
