Clear skies over the Alps, after few days of cloudiness, revealed fresh snowfall (shown in cyan colour) over the high ground. In some areas, mainly in Austria and parts of northern Italy, more than 30 cm of fresh snow was reported, with the most falling on 26 August. Clouds that obscured the Alps during that period, and brought precipitation to the area, were connected to the cold front passing over central Europe (Figure 2). The cold front passage cooled large areas of Europe and ended the very warm, and in some areas the very dry, conditions.
