Dynamic weather situation

mild southwestern position
A low pressure system mov from the British Isles to southern Scandinavia today. A southwesterly flow prevail over Switzerland, bringing very mild air to the northern side of the Alps.

A low with its core between the British Isles and southern Scandinavia is controlling a frontal system across Central Europe.

This meant that today the thermometer rose to spring-like temperatures of around 17 to 21 degrees, particularly on the northern side of the Alps. This is unusually mild, especially for the first half of March. In northwestern Switzerland in particular, temperature records for the first half of March were broken in some places. For example, in Basel Binningen. Here, the previous record of 22.5 degrees was exce by almost 1 degree with a daily maximum of 23.4 degrees.

In the first half of the night on Tuesday, the low pressure system with its core over southern Scandinavia will drive a cold front over the northern side of the Alps. As a result, the air pressure on the northern side of the Alps will rise rapidly and the foehn situation will end. As the cold front passes through and the pressure increases with it, the wind will pick up on the northern side of the Alps. Stormy winds are expect in western Switzerland and over the Jura. This region has been warn with a level 2 wind warning (see warning map above). In addition, thunderstorms may develop along the frontal zone, particularly in western Switzerland and the Jura.

Tomorrow, Tuesday, another cold front will follow, crossing the northern side of the Alps during the day. As the cold air flows in, the pressure on the northern side of the Alps will continue to rise, which will be accompani by strong gusts of wind. The wind spes on the northern side of the Alps will probably reach 70 to 90 km. As a result, another level 2 wind warning has been issu for the northern side of the Alps.

Behind this, cooler air is not only flowing in into the lower layers. Cold air is also reaching us at higher altitudes. As a result, the air is unstable and isolat thunderstorms are likely to develop in addition to showers.

From southern to northern overpressure

 

As the cold air flows in and the pressure rises as a result, the hague academy of international law courses pressure gradient over the Alps turns and the southern overpressure becomes northern overpressure. This causes moisture to accumulate on the northern slopes of the Alps, and between Tuesday night and Wnesday afternoon, 20 to 60 cm of fresh snow is expect on the northern adb directory slopes of the Alps. This has again been warn against with a level 2 warning.

he evening hours. We have therefore issu a level 3 warning for the typical foehn regions.
