Planning Outlook
Chilly and showery conditions to start the new week, hail and a risk of isolated thunder into Monday afternoon, but less windy than the weekend. Drier for much of Tuesday, but rain and strengthening south-southwesterly winds likely return from the west later. Milder into mid-late next week, but Scottish high tops above 1200m close to freezing at times. Showers or more persistent rain mostly in the west, accompanied by strong winds Wednesday-Thursday. Higher pressure builds toward next weekend, bringing drier conditions overall; some chilly nights but fairly mild spring days.
