Friday
High pressure broadly encompasses the British Isles, bringing a benign and rather murky day to most places. A weak front across eastern regions will produce drizzly outbreaks of rain, perhaps locally a heavier shower near the east coast. Areas of low cloud will persist, but some sunshine is likely for central & western regions. Local fog patches. A frosty start in the south-west. Highs 5 to 8C.

Friday night
Extensive cloud is likely to cover much of Britain and Ireland, preventing a frost for many places. A damp atmosphere, with a few patches of drizzle possible, but amounting to very little in total. Some patches of fog, particularly across the hills, but locally at lower levels too. Winds generally light. Temperatures 3 to 6C, perhaps dipping close to zero where cloud breaks in the north & west.

Saturday
A fair day across most areas, although a lot of cloud. Many places in England & Wales may remain murky all day, although some sunshine will try and break through, particularly to the west of high ground. Scotland should fair better for breaks in the cloud, and the Highlands may see a good deal of sunshine. Light winds for most, but an easterly breeze will freshen in the south. Highs 5 to 8C.

Sunday
High pressure centred toward the east maintains settled weather across the British Isles. Dry for all. Frosty in rural areas to start the day, particularly in the north & west. Some fog patches. A good amount of sunshine overall. A brisk easterly breeze across central & southern Britain, strongest around the south coast, making it feel cool. Top temperatures 4 to 8C.
