Clouds in Kehrsatz near Bern
These clouds were photograph this morning in Kehrsatz near Bern. They are so-call “altocumulus stratiformis opacus asperitas”. This describes layer (stratisformis) altocumulus clouds in which the sun (or moon) is not visible through the clouds (opacus = dark, opaque). “Asperitas” is a rather rare special form and means “roughen or agitat”. It forms on the underside of the clouds, is characteriz by rippling, wave-like structures and resembles the surface of a rough sea.

On the back of the disturbance, the cold air flowing in from the northwest will cause changeable weather on Saturday with showers and sunny spells, accompani by strong westerly to northwesterly winds. On Sunday, an active disturbance system will bring further precipitation with snow above around 1200 meters. The following polar air will cause the snow line to drop to low altitudes on Monday. While persistent snowfall is likely on the northern slopes of the Alps, in the lowlands there will probably only be isolat snow or sleet showers.

>Ensemble forecasts from the European weather model for air mass temperature at an altitude of around 1500 meters (above) and precipitation (below) for Zurich. The precipitation signals from Friday to Sunday as well as the advance of polar air in the night to Monday with a drop in temperature are clearly visible. However, this is likely to be only a short (W)intermezzo, as temperatures will gradually rise again afterwards. While the uncertainties, especially with regard to
