Planning Outlook
Weather patterns remain slow-moving, but high pressure tends to build into midweek to bring a fair amount of dry weather which may well last through next weekend. Briefly cooler in northern Scotland early in the week, but mostly fairly warm and winds often light. Some rain-bearing fronts may return to northwestern Scotland at times. Occasional scattered showers in the afternoons elsewhere.
