Ames is roughly located at the center of the state, so as a first approximation does its yearly precipitation total reside in the middle of the statewide distribution? The featured chart attempts to address that question with the caveat that no spatial weighting was done to the available observation dataset. Putting that aside, the top panel shows the percentile rank of Ames precipitation vs the statewide dataset by year. While the overall average is near 50%, the year to year variability is high. The bottom panel shows the yearly different to arithmetic mean of available data for the year. The overall bias is slightly negative, but close to zero. So in this case, being in the physical center of the state equates to the middle of the precipitation dataset over the long term.
