Read the freezing level before the snowfall total. The headline number only helps once you know whether Sea of Japan storm flow is the pattern to watch. With a 350 to 1000 metre elevation band and 650 metres of vertical, the groomers tell the story quickly once the first few laps are done. A seasonal baseline around 10 metres means moderate-looking totals can still refresh the main lines quickly. The swing variable is whether the snow line stays below the 350 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 10 to 20 cm lands cold to the base; skip it when the forecast shows a warm lower mountain.
