Yesterday's Daily Feature took a convoluted look at how efficient Monday's rainfall was at covering the driest areas of the state. Today's featured chart presents a different approach attempting to answer the same question of how effective Monday's rainfall was. The chart uses a RADAR based precipitation estimate product to first compute the Iowa coverage percentage of receiving at least an half inch of precipitation and what percentage of the area coincided with an area that received less than the same half inch over the previous seven days. The bottom panel is a more straight forward accounting of the daily area of the state covered by such a precipitation event and the dry area of the state under half inch over the prior seven days. The rain toward the end of May and Monday's were certainly much needed and benefited most of the state.
