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 West Pasco itself (about a 3-mile square). Snow, frost dates and day counts: the NOAA station at Ice Harbor Dam, WA (15 mi, snow) and Richland, WA (6 mi, frost, heat and degree days). Sunrise and sunset are calculated from the town’s position. Normals are 30-year averages, not a forecast.
