Planning Outlook
Remaining warm and humid through the weekend, particularly in western regions, whilst eastern areas are cooler under North Sea air, which brings a risk of lingering fog banks. The Scottish Highlands stay extensively dry. Thundery rain mostly confined to Wales, although rain may expand back northwards into the Pennines by Sunday. Into next week, light winds and areas of slow-moving showers at first, then a gradual change is likely as windier conditions move in from the Atlantic, with belts of rain or showers.
