Read the freezing level before the snowfall total. The headline number only helps once you know whether cold air spilling over the Tohoku spine is the pattern to watch. With a 400 to 1000 metre elevation band and 600 metres of vertical, the bigger vertical gives you room to move higher when the lower runs soften. 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 400 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.
