Switzerland lies between a low over the Baltic and a low over the Iberian Peninsula. A high with its centre northwest of Scotland is increasingly determining the weather. Yesterday afternoon Switzerland was still in an unstable southwesterly flow, in the evening the low in the northeast directed a cold front to the northern side of the Alps. Today, Saturday, the front settled on the northern slope of the Alps. The upper air flow behind the front turned to the northwest, which caused the moisture to accumulate somewhat on the central and eastern northern slopes of the Alps. Colder air is now flowing in behind the front. In addition, the high is increasingly expanding towards us, causing a bise situation. Tomorrow, Sunday, the upper air flow will also turn to the northeast, which will make the bise even stronger.

Overall, 20 to 35, and locally up to 45 mm of precipitation fell on the northern slopes of the Alps east of Lake Lucerne. In this region and in northern Graubünden, snow measurements from 7 a.m. this morning also recorded some fresh snow: 2 to 7 cm above around 1,000 meters, and 1 to 4 cm of fresh snow in the eastern foothills of the Alps above 700 meters. However, the snow has continued to fall since then, particularly in the east, so a few more centimeters are likely to be added in one place or another.
