Confidence builds: 31.1cm for Artesina Nov 16–18
The prediction for the mid-November North Atlantic system indicates 31.1cm for Artesina over the window, with a range of 0–73.9cm. The biggest day is expected to be November 17, with 15.6cm. Current patterns suggest a favorable setup for snowfall across the Alps and wider Europe, but confidence remains moderate as we continue to monitor trends. Artesina is positioned to benefit significantly from this system, while other resorts are not included in this entry and therefore remain unassessed. Changes in the prediction could occur if model outputs shift significantly in the coming days, particularly regarding the storm's intensity or track.

Above the summit line it rains on the whole mountain; below the base line it snows all the way down. Blue bars are snow in cm, amber bars rain in mm; the totals above are their sums.
