Comments

The snowfall year-to-date starts on September 1. Sometimes the daily updates of these maps fail, in which case the maps for the Midwest from the Applied Climate Information System are a possible substitute.

The data used in these products come from the National Weather Service (NWS) Cooperative Observer Program (COOP). This network of more than 11,000 volunteer observers nationwide, using approved instruments and observing techniques, provides high-quality climate data to the nation. The data are archived at the National Climatic Data Center (NCDC).
