This is a story about a little storm, that tried to conquer the world from Greenland. With only 1015 hPa it was hardly visibile on the weather maps. I’ve marked that little storm with a green arrow for your convenience.
20 centimeters of freshies
That little storm needed help from her big sister: storm Gisi. Gisi is a pretty big storm that planned to bring plenty of snow to the Alps. The one thing she didn’t take into account was high pressure trying to keep her at distance and she decided to help Gisi. Gisi will bring the first northern Stau to the Alps on November 3rd and 4th, but you don’t have to expect more than 20 centimeters. The snowline will drop to 1000 meters on the north side of the Alps. High pressure area Rafael prevents Gisi of dumping more snow in the Alps.
Gisi will travel east and forces Rafael to split up. One part of this high pressure area will follow Gisi to the east and the other part of Rafael will stick around at the Atlantic. And that little storm dives into the corridor and will bring some snow to the Alps.
That little storm enters continental Europe bringing lots of cold air in the night from Friday to Saturday (you can see the cold air on the map below on the left side).
Some snow for the (southern) French Alps
That cold air will bring some snow to the highest peaks in Scotland, but it will also bring some snow to the Alps. The (southern) French Alps will get some snow first followed by the other regions in the southern Alps, as you can see on our snow maps.

The snow line is pretty high at first, but will drop in the western Alps during the weekend. Austria and Switzerland will have to deal with a southern Föhn that will melt all the snow below 2500 meters. The models don’t agree if there will be more snow coming down later this week. GFS is showing some high pressure again, but the European model sticks to more precipitation.
Let’s follow this little storm the next couple of days. It will get colder and snow will fall. Winter is coming!
Stay stoked. Morris
