Field notes
The page explains that NOAA’s snowfall analysis combines radar-based precipitation estimates, a snow-to-liquid ratio, and observer reports. Its totals use fixed windows ending at 12:00 and 00:00 UTC, appear about two hours later, and can be revised for roughly five days. SnowDex limits coverage to the contiguous United States and cautions that a grid estimate is not a measurement at the door.
