WeatherBlog 18 2022/23 | Spring-like changeable

In the next few days, it will become increasingly unstable. The high pressure will gradually be pushed out of the way and we will find ourselves in a cyclonic (low pressure influence) situation with more or less the same direction of flow. Tomorrow will probably be cloudier again and the wind will pick up. You probably won't be able to ski in the rain yet, at most there will be a few drops. The chances of precipitation are better on Friday. You might even be able to ski in thunderstorms (not recommended, of course)! A cold front will bring rain in the course of the day and some fresh snow at high to very high altitudes - it's likely to remain below alarm levels everywhere. From today's perspective, the snow line will be somewhere around 2000m, possibly much higher in the western Alps. The thunderstorms embedded in the disturbance can also be interpreted as harbingers of spring: Thanks to increasing solar radiation (the equinox has just occurred!), it is already quite warm on the ground and in the air layers close to the ground. When cooler air flows in at altitude, the result is an unstable bottom-warm-top-cold stratification, which is very conducive to thunderstorms.

Unclouded sunshine and correspondingly good firn conditions are therefore unlikely over the next few days, but perhaps a few centimetres of snow will fall, at least in the high mountains. The relatively mild and unsettled westerly weather will remain with us at the weekend in a slightly different form. It's likely to be wet and colder at the beginning of next week. We're not going to go out on a limb just yet, but maybe winter will actually drop by again before the remaining snow has completely melted...
