Temperatures and rainfall come from NOAA’s gridded climate normals for Prospect itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Boonville 4 Ssw, NY (14 mi, snow) and Trenton Falls, NY (2 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.
