Planning Outlook
West to southwesterly winds prevail later this week and into the weekend and further weather fronts will come in off the Atlantic to bring low cloud and rain especially to western mountains in Scotland. A brief ridge of high pressure this Thursday offers a better day with the wind lessening for a time and fewer showers, but winds likely strengthen again by Friday, toward gale force over northwestern Scottish mountains at least. Heavy rain likely affects western Scotland on Saturday, becoming widely showery into Sunday. A brief window of improvement is indicated early next week, but a generally unsettled theme likely continues into mid-month.
