Rain and even some snow over the northern counties looks very likely today over Iowa. These type of events do not simply rain for an hour and then stop, but persist over a number of hours as the large storm complex passes by. The featured chart presents the frequency of an hour with measurable precipitation for a given month being followed by another hour with measurable precipitation. The lowest frequencies are found during the summer months as thunderstorms tend to be more isolated in nature. The lower values during the winter are likely due to having less intense precipitation events with some hours barely measuring one hundredth of an inch.
