Planning Outlook
Low pressure initially to the north of Scotland early in the new week will eventually envelop the whole of Britain next week bringing generally unsettled and cooler conditions increasingly widely. Often blustery widely, west turning northerly winds later in week - becoming notably chilly over higher mountains. Rain extends into Scotland on Monday, turning heavy, then moves south over England and Wales by Monday night into early Tuesday. The rest of the week sees showery rain common for all areas, the rain most persistent in western Scotland, but heavier showery bursts and thundery downpours become widespread mid to late week.
