Read the temperature trend beside the fresh-snow number. 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 1200 metre elevation band and 260 metres of vertical, the groomers tell the story quickly once the first few laps are done. A seasonal baseline around 9 metres means small clean refills matter more than waiting for a giant number. The swing variable is storm timing, because an overnight finish skis very differently from an afternoon pulse. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase it when the storm exits cold and calm; skip if the tail end turns wet or windy.
