Snow, frost dates and day counts come from NOAA’s weather station at Camden, NY (19 mi, snow) and Rome Griffiss Airfield, NY (5 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000. Today’s forecast: National Weather Service.
