Planning Outlook
A window of more settled weather continues into Sunday as high pressure extends over Britain. Clear night skies allow for chilly mornings with ground frosts, some valley mist particularly in Scotland. The new week starts with some rain and wind in Wales and south Pennines, more settled to the north but with strengthening wind and building cloud as well. A general unsettling trend indicated through next week as winds return to Atlantic southwesterlies. A few windows of brighter weather in eastern areas, but a rising risk of strong wind and heavy rain into late week and next weekend.
