Planning Outlook
Rain, drizzle and low cloud persist over western hills from Lake District northward into early next week. Temperatures near average, but feeling cool in exposure to wind on tops, quite strong and gusty central and south Scotland. Northeast areas are drier with higher cloud bases but rain reaches here too. Higher pressure south maintains drier conditions in Wales and the south Pennines but cloud and some drizzle will affect high western slopes from time to time; lighter wind here, but nuisance gusts in exposure. A drier and warmer window builds into the middle of next week: very warm in England and Wales, spells of sunshine spread northward, and lighter wind. Some showers and patchy rain continue through late week and next weekend, though detail is uncertain and more often dry.
