Many hills often free of low cloud. By Tuesday into midweek, as fronts edge back in from the west, bursts of rain are likely to develop, locally thundery. Southwesterly winds are expected to prevail later in the week, with rain at times, most frequent in W/NW Scotland. Some windy days with possible gales for the Highlands.
