Planning Outlook
Prolonged rain will leave flooding of streams and rivers in many mountain areas early in the new week, with the exception of northeastern Scotland. As a front clears Monday into Tuesday it will drop to freezing above 900m, beware of ice forming on higher Scottish mountains. Drier conditions for many on Tuesday, though showery near west coast of Scotland. By Wednesday, another system sweeps in from the Atlantic bringing further rain and gales. A risk of more heavy rain particularly England and Wales later in the week. A change of weather pattern is likely in the run up to Christmas, as high pressure builds northward, bringing drier weather, possibly chillier with time.
