That's not quite right. Haven't you heard of a Rain-fall gauge?
Rain pelts, torrents buckets down, comes in a deluge, rains pitchforks, cats-and-dogs, hisses down et cetera.
Whilst snow 'flurries' wafts, drifts, precipitates (they both do that) and is generally much more airey-fairey. Until you have to shovel it away.
Then you get all 'steamed' up when it becomes icy.
