Biggest Rainfall in February
Posted: 18 Sep 2023 05:30 AM
The featured chart is a bit of a complicated look at precipitation metrics over the state for this year. The top panel estimates the areal coverage of Iowa receiving at least a daily one inch precipitation total for the given date. The colors partition the area by how much of that precipitation fell over locates that were below an inch total over the previous seven days. This is attempting to measure an effectiveness as you generally want precipitation events to fall on locations that need it. The bottom panel shows the areal coverage that needed rain and got the rain. Of interest is that the highest percentage shown was for an event on 27 February! The lack of big rainfall events during April through June is readily noticeable and a couple of events during July and August were likely saviors for the agricultural crops that were running short of moisture all season long.
