"A long-duration Wednesday night (01/07) through Friday night (01/09) storm brings the core of the week's snowfall, with the most productive window concentrated Thursday night into Friday night. Snow levels start very low Wednesday night, then climb Thursday into Thursday night (often into the 2,000-3,900 feet range), which can briefly compromise lower elevations before colder air works back in by Friday night."
"The biggest totals pile up across the western French resorts, where Chamonix and the upper Tarentaise cluster (Val Thorens, Tignes, Courchevel, Val d'Isère) generally land in the 26″-58″ neighborhood for the full storm window, while open Verbier checks in at 27″-43″. Snow quality during the heaviest push is mostly fair to good, with SLRs commonly around 11-16:1 in the thick of Thursday night snowfall, improving into the mid-teens and upper teens as colder air filters in."
A multi-day storm cycle peaks late Thursday night through Friday night, then reloads with a colder weekend refresh and a milder taper early next week. The western French Alps, led by Chamonix and Val Thorens, will see the highest accumulations (roughly 26″-58″), with many nearby areas receiving 26″-48″ and Verbier around 27″-43″. Snow levels will oscillate—briefly higher Thursday (often 2,000–3,900 feet), then very low over the weekend (commonly 500–700 feet), before rising sharply Monday. Snow-to-liquid ratios favor colder periods, with SLRs near 11–16:1 during the core storm and improving into the mid-teens to ~20:1 over the cold weekend. Occasional 20–30 mph gusts may impact exposed ridgelines.
