Planning Outlook
A cool northeasterly wind into Monday brings a scattering of showers, but plenty of dry weather too. High pressure stays nearby to the north of Britain through the week ahead giving a run of dry days with sunshine typically best in the west, but many mountains often free of low cloud. A cool easterly wind prevails for England and Wales, strongest toward the south, whilst Scotland has often lighter winds. Some overnight frosts. Daytime temperatures near average, typically a few degrees above freezing on high tops through midweek. Dry, settled conditions are likely to continue into next week.
