Planning Outlook
An unsettled southwesterly weather pattern continues mid-late this week. On Wednesday, another system sweeps in from the Atlantic bringing further rain and gales. Showery conditions then persist in western Scotland, with hail and snow on high tops. Scottish mountains often near or below freezing above 900m, only brief thawing higher up. Meanwhile, England and Wales stay mild midweek with more heavy rain likely into Thursday, then lowering to freezing on high tops for periods from Friday. A change of weather pattern is likely in the run up to Christmas, as high pressure builds northward, bringing drier weather, fog and frost more common.
