The primary planning issue in this profile is site design and equipment selection rather than severe climate. The standardized 9 kW session estimate is $2.26, below the indexed-metro median of $2.46; this uses the North Carolina statewide residential electricity average, not a city utility quote. The selected snowfall record reports 3.5 inches annually.
For construction or maintenance work that is easier in moderate conditions, the monthly normals point to February, March, April, May. This is a climate-screening observation, not a construction schedule or permit recommendation.
