Planning Outlook
Thursday remains dry and exceptionally hot across England and Wales; very dry ground conditions. Rain will begin to spread across Scotland through Thursday, this slipping into England and Wales on Friday and bringing a fresher breeze with its passing. Though weekend, high pressure is never far away to the southwest, keeping conditions generally drier and brighter across England and Wales, though a northwesterly flow will bring some cloud to western hills. Scotland is more often cloud with patchy rain in the north and west. Mixed conditions early next week with patchy rain and sunny bursts here and there. With time, a trend towards stronger westerly winds with a few spells of more widespread rain; forecast confidence is low beyond the weekend.
