The snowstorm of February 16 to 20, 2021

The Regional Snowfall Index is NOAA’s ranking of snowstorms east of the Rockies by how much snow fell, over how wide an area and on how many people, region by region: the area and the population above four snowfall thresholds set for each region, weighted against that region’s own history. A storm is scored in each region it reached, on a scale from 1, notable, to 5, extreme.
