We are watching a significant system for the Alps and wider Europe between 2026-11-02 and 2026-11-04. Narvik carries the biggest signal at 11.8cm over 2026-11-02 to 2026-11-04. At Narvik the freezing level on the snow days sits between base and summit: snow on the upper mountain, rain possible low down. The call changes if model agreement loosens, the window slides later, or the freezing level trends higher.
Snow by day
Nov 1 – Nov 5, with a day either side. For each resort: where the freeze line sits against the mountain, then what falls — snow in cm, rain in mm — and the day read from those two numbers.

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.
