Planning Outlook

West-southwesterly winds will bring rain to most places early in the new week, some more prolonged heavier falls for western Scotland by Tuesday, accompanied by gales over high terrain, severe on Scottish tops, but rather humid for all, warm for England and Wales. Cooler air toward northwest Scotland moves across all of Scotland by Wednesday. Showery rain through mid-late week, some heavy and possibly thundery bursts, mainly Scotland. Likely drier for Wales and southern Pennines. More uncertainty toward next weekend and early the following week, but a risk of a broad zone of low pressure bringing areas of rain and heavy showers through early August.
