Another area to be careful with 10:1 ratios is hourly snowfall rates, as ratios in the NYC metro will be below 10:1.

I have two different metrics for HRRR hourly snowfall on my website - snow rates over 1"/hour are expected where the snow band ends up.https://t.co/43at44pqeg pic.twitter.com/QbbwrmyeSt
