Planning Outlook
Unsettled weather persists into early next week. A relative lull in the early hours on Monday for north Scotland before the next weather system soon sweeps in from the southwest with drizzle, some heavy rain, and extensive mountain gales. Temperatures will be unseasonably mild. Rain breaks into showers for most on Tuesday with cooling temperatures, becoming snow on high terrain. Gales remain widespread, severe conditions persist over Scottish Highlands. Pressure slowly builds from the south into Wednesday and Thursday; staying blustery, cloud and some showers affecting western areas, but bright spells breaking out, briefly more settled in England and Wales. Confidence in forecast detail is low into next weekend, but western hills are likely wet again, more widely cloudy with cool to mild temperatures.
