These thirty-year averages, computed from station USC00246157, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Norris Madison Pwr House receives roughly 18.4 inches of precipitation each year, with 51.8 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near April 30 and the first fall freeze near October 10. For energy use, 6,262 heating degree days and 523 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Norris Madison Pwr House scores 47/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for December-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
