Forecast, conditions and alerts: National Weather Service. Climate: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000. Temperatures and rainfall come from NOAA’s gridded normals for Portage Des Sioux itself (about a 3-mile square). Snow, frost dates and day counts: the NOAA station at St Charles Elm Pt, MO (12 mi, snow) and St Charles Co Airport, MO (5 mi, frost, heat and degree days). Sunrise and sunset are calculated from the town’s position. Normals are 30-year averages, not a forecast.
