This Evening and Tonight:

Cloudy this evening with hill fog lingering across the higher ground and outbreaks of showery rain and hill snow pushing north and west overnight. Winds easing but remaining cold with a frost in rural parts by dawn. Minimum temperature 1 °C.

Saturday:

Grey and rather gloomy with low cloud bringing hill fog and patchy rain, with some wintry flurries over the hills. Brighter across Anglesey but chilly for all with light winds. Maximum temperature 7 °C.

Outlook for Sunday to Tuesday:

Mostly cloudy through Sunday and into next week with rain and drizzle at times, perhaps falling as snow over the mountains. Feeling cold, especially in the wind.

High pressure is expected to be slow moving and centred to the northeast of the UK at the start of this period. As a result, east or southeasterly winds will dominate, these bringing below-normal temperatures across the UK from mainland Europe. Some rain and hill snow is likely at times, particularly across the east of the UK, with the best of any sunny periods probably in the west. It will be breezy around coasts, but the risk of any very strong winds is low. During the second half of this period, a change to milder and more unsettled conditions will probably begin to occur. Exactly how this manifests is uncertain, but there will be an increasing chance of rain and strong winds spreading from the Atlantic across the UK.

A mobile pattern, will probably have become established by this time, with weather systems moving close to or across the UK from the Atlantic. This will mean bands of rain and perhaps periods of strong winds spreading in from the west, interspersed with some drier and brighter interludes. Temperatures are most likely to be close to average overall.
