NOAA/NWS/NOHRSC’s original picture and legend. No station or address value is inferred.
NOHRSC footprint times are metadata; pixel analysis time is not independently verified. Snow-depth pixels have previously differed from the footprint time. This is modeled/assimilated snow analysis, not a measurement at a place. Unshaded and no-data areas do not establish zero snow.
Collector checked not reported; feed generated not reported. Zero cells does not establish coverage or clear weather. Observations from different radars are not merged.
The polygon is a warned area, not a tornado footprint. NWS detection tags are independent of radar algorithms and reports.
