Planning Outlook
Some rain and a fresh northwesterly breeze slips into England and Wales on Friday. 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 cloudy with patchy rain, mostly north and west. Mixed conditions early next week with periods of rain and sunny bursts. High pressure remains present to the southwest of the British Isles, maintaining the possibility of drier brighter days; detail remains uncertain regarding risk of more unsettled weather. Temperatures likely nearer average.
