Read the freezing level before the snowfall total. Here, Sea of Japan storm flow is the pattern to watch, so the useful question is how cold and calm the next window stays. With a 300 to 860 metre elevation band and 560 metres of vertical, the gladed pockets are the first place to check once the groomers get tracked. A seasonal baseline around 7 metres means small clean refills matter more than waiting for a giant number. The swing variable is whether the snow line stays below the 300 metre base through the storm. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase it when 5 to 15 cm lands cold to the base; skip it when the forecast shows a warm lower mountain.
