Service Description: .
This map shows the earliest first day of snow recorded at thousands of locations in the United States during their period of operation. Map based on an analysis of Global Historical Climatology Network (GHCN) station data by Jared Rennie, NOAA's National Centers for Environmental Information (NCEI). Light colors indicates places where the first recorded snowfall happened early in the season, in July or August. Shades of blue and purple show places where the earliest snow fell between between August and May. While the map shows the earliest date of first snow recorded at a given station, this map should not be interpreted as the “earliest ever” first snow of the season. It is simply the earliest date of first snow at a given station during its period of operation.
For a more detailed assessment of the earliest date of first snow, please see this Climate.gov blog post. For more information about the Global Historical Climate Network, please visit the GHCN description page
