The line is the average temperature and the bars are average precipitation at Fenn RS, 11 miles from the center point at 1,560 feet, station USC00103143 in the NOAA monthly climate normals for 1991 to 2020. Precipitation totals about 41 inches a year. The dotted line is average snowfall, about 43 inches a year on the same inches scale. The station sits about 2,800 feet lower than the center point, so temperatures on the ground run cooler.

Large units span more than one climate. The station stands in for the center point, and the outer parts of the boundary can be warmer or colder.
