Planning Outlook

Low pressure continues to dominate early in the new week, maintaining unsettled conditions widely. Areas of rain and heavy showers, risk of hail and thunder. Windy, gales over mountains early in the week, tending to ease for periods at least in the Highlands mid-late week, whilst southwesterlies often remain strong over England and Wales. Some improvement possible toward next weekend, though the extended outlook into the second week of September remains changeable. Mid-September shows signs of a better improvement as pressure tends to rise more widely.
