Planning Outlook
Higher pressure to the southwest this weekend, bringing warmer and drier conditions to Wales. Showery rain affecting Scotland on Saturday, some patches reaching northwest England; staying very windy and cool in Scotland and northern England on Saturday too. Sunday will be a clearing day for most: early rain in Scottish Highlands easing and most cloud lifting off summits, sunshine but weakened by high cloud. Temperature more widely mild, warm in Wales. Into next week, a mixed southwesterly pattern remains, windy at times with periods of rain, drizzle and low cloud most persistent in the west. Warmest in England and Wales, but cooler westerly air likely returns at times mid-late week. Pressure generally trending higher, but extensively settled weather may remain elusive in the near-term.
