Likewise when I was a young teen I would hope for an unforecast event of major snowfall. Though still kind of rare, unexpected dumps did happen back in the day. Especially out west. Of course, what I didn’t understand was that they usually didn’t happen if the forecast was clear and sunny, or if the forecast snow level was 4,000 feet above my location.
it’s more a matter of underestimating accumulations or slight deviations in track or temperature that do it. And stationary bands.
