"The Tue night (02/10) - Fri (02/13) storm brings the deepest snow of the period and the clearest model agreement. The ECMWF, the AIFS, the GFS, and the ICON all stay meaningfully wet across the French Alps, and the GDPS is the main drier outlier in a few central-Alps pockets, so totals vary more from resort to resort in Switzerland and near the Italian border."
"Snow levels run roughly 1,250 to 1,550 meters early, then settle closer to 950 to 1,150 meters late, which keeps higher terrain firmly in snow while the lowest bases (especially those under about 1,000 meters) see more sensitivity to brief warmer pulses. SLRs in the French Alps generally sit around 11-14:1, so snow quality trends moderate to fairly good, while some lower northern and eastern hills see denser intervals closer to 7-10:1."
An active period begins with a major midweek storm from Tue night (02/10) through Fri (02/13) that favors the French Alps and western Switzerland, producing higher-elevation totals around 80–150 cm while snow levels gradually lower. A secondary system from Fri night (02/13) into Sun (02/15) will add roughly 5–25 cm, refreshing surfaces and improving snow quality while helping valley bases remain snowy. Several models agree on a wet signal across the French Alps, though some central-Alps pockets show drier bias. Snow levels drop from about 1,250–1,550 m early to 950–1,150 m late, SLRs near 11–14:1, and winds mainly moderate with ridge gusts to 40–60 km/h. After Sun night (02/15), system placement and rain-snow line wobble increase forecast uncertainty.
