Look at the most recent 12 hours, not the weekly total. Here, a cold inland trough is the pattern to watch, so the useful question is how cold and calm the next window stays. With a 940 to 1155 metre elevation band and 215 metres of vertical, the whole hill changes quickly because the elevation band is compact. A seasonal baseline around 3 metres means freshness and temperature matter more than chasing a big total. The swing variable is timing, because the compact footprint gets tracked or softened quickly. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase a cold morning immediately after fresh snow; skip warm afternoons unless you are there for relaxed laps.
