First Widespread Half Inch

Posted: 07 May 2018 05:34 AM

Last week was our first significant wide spread rainfall event of the season as depicted by the featured chart. The top panel shows the areal coverage within the state that picked up at least a half of an inch over a trailing seven day period. The bottom panel looks at the efficiency of that rainfall with the tan area representing how much of the precipitation fell over an area that was sub half an inch prior to the event. Complexity of the plot aside, the recent week of rains were needed over much of the state, but some parts of the state, particularly northern Iowa need some more dry weather.
