Saturday
Much of England and Wales will be a dry and fine day with variable cloud and sunny spells. Thicker cloud and outbreaks of rain will push in across Scotland, Northern Ireland and Ireland through the day, eventually pushing in to northern England, north and west Wales by late afternoon. Drier, brighter and cooler conditions develop behind the rain, though expect wintry showers across the NW Highlands and scattered rain showers across the Northern Isles. Highs at 7 to 11C.

Saturday Night
Cooler, clearer conditions push across the country from the north through the night behind the cloud and patchy light rain as it moves south through England and Wales. Lows dropping to below zero where the skies clear in the north and west, 0 to -1C, lows around 2 to 5C further south.
 

Sunday
A chillier start on Sunday with frost expected for many as a ridge of high pressure builds in across the country. Possible mist and fog to start but these should soon lift to give a largely dry and fine day with plenty of sunshine. Highs at a cooler 5 to 7C.

 
 
 

Monday
A chilly and frosty start for many again on Monday. A largely dry day though cloud will be thicker across the north and west where it could produce some light rain and drizzle for a few. Elsewhere will be bright with sunny spells away from any mist and fog patches. Highs at 5 to 8C.
