Tuesday was a good powder day. The sun came out and because of the fresh snow and the wonderful weather, a number of powder chasers decided to extend the weekend. And for a reason. The powder was still cold in the morning and the sky was blue. A wonderful day in March.
In the meantime, a new front appeared in the west towards the end of the day. The wind turned a little to the southwest, it became milder and higher clouds appeared. Storm Franz is on its way to Europe and the result is once again a lot of snow for the northwestern Alps. The first front will pass this night.
The most snow will come down around Mont Blanc and the Dents du Midi up to and including tomorrow morning (that's on the border of Switzerland and France). The extreme west of Wallis, just like the northeast of the Haute Savoie can expect the most snow. In addition, I expect 15-30, locally maybe even 35 cm of fresh snow. In addition, the resorts in the Swiss northern alpine ridge can expect 10-20 cm. Just enough to fill in the old traces and turn Wednesday into a powder day in:
Because the front has largely passed on Wednesday morning, there is also room for sun during the day. But the duration, the location and the intensity are always difficult to predict with the passage of such a cold front. But expect cold powder and maybe even some sun.
It won't be long, because the second front follows in the course of Wednesday and brings a lot of snow until Thursday. Especially Thursday afternoon. The snow line is again low (900-1200 meters) in the west and around 600-900 meters in the east. A significant amount of snow will fall, as in a thick layer of snow in the northwestern Alps. Below the expected snowfall on Thursday.
Thursday morning and certainly Thursday afternoon you can ride treeruns in:
Thursday is going to be deep and we will ride good treeruns in mid-March. But then the mild Friday.
A warm front follows on Friday. The temperature rises again, just like the snow line. You won't really notice this in the inneralpine valleys because the air in the valleys is still cold here. But because the warm front is pretty persistent and it's impossible for cold air to reach the Alps due to a high pressure area, it will be milder from Friday.
Expect that Friday starts with rain up to 1000-1500 meters in the Alps in France and Switzerland. At the same time it snows deep into the valleys in the inneralpine valleys of France and Switzerland. We also see the same scenario with 4 to 8 hours delay in Austria. The snow line may still rise towards the 1700 meters and it will only freeze above 2000+ meters later in the day. This will result in an interesting avalanche situation. More about that tomorrow.
It is the prelude to a sunny but mild weekend. Forget the treeruns this weekend. On Saturday and Sunday you want to ride powder in the higher parts of the Alps as it looks right now. The sun comes out and it becomes great riding powder on northern slopes in the areas mentioned above. More details tomorrow.
Still very far away, but more and more models assume that it will stay mild after the weekend. Especially since the last runs aren't that positive. A front moves into the Alps on Monday / Tuesday. The supply direction and snow line still uncertain. That's why ... if you have time, enjoy the fresh snow now. Thursday in particular is going to be DEEP. We will see what will happen, but this is on the menu for this week:
