Read the freezing level before the snowfall total. The headline number only helps once you know whether west to northwest flow off the Sea of Japan is the pattern to watch. With a 323 to 479 metre elevation band and 156 metres of vertical, the gladed pockets are the first place to check once the groomers get tracked. A seasonal baseline around 8 metres means small clean refills matter more than waiting for a giant number. The swing variable is whether the snow line stays below the 323 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.
