The 2020 year-to-date precipitation total for Des Moines is presently very close to long term average both in terms of overall total and daily binned contributions. The featured chart presents a histogram of daily precipitation totals with the bins determined by partitioning the long term daily precipitation totals into equal rain volumes. Rewording, each of the five bins shown contributes, on average, 20% of the yearly precipitation total. This plot drives at the relative importance of having many days with light precipitation vs having those big rainfall events. For the year to date period, that ratio is over 20.
