Planning Outlook
Westerly winds with some drizzle over high ground prevails in northern Scotland into Saturday, then high pressure establishes over the British Isles bringing light winds and dry weather conditions well into next week. Scope for inversion conditions this weekend and early next week with some valley fog and varied low cloud. Into the week, mixed cloud and sun with occasional longer spells of cloud or sunshine. Easterly winds are expected to increase with time for England and Wales, particularly in the south where there could be notable gusts over high terrain. Pleasant daytime temperatures, some cooler nights with slight frost where skies are clear.
