Temperatures and rainfall come from NOAA’s gridded climate normals for Odessa itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Geneseo, KS (10 mi, snow) and Kanopolis Lake, KS (8 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.
