The updated United States Drought Monitor last week included the worst category of D4 (Exceptional) for a very small portion of the state near Sioux City. This is the first D4 designation in Iowa since at least the year 2000. The featured chart presents the weekly areal coverage of the drought categories since 2000. The small D4 percentage is not legible on this chart and hopefully it does not increase in size going forward! The D3 (Extreme) category is also at the largest percentage for Iowa since 2000.
