The weekly update to the US Drought Monitor was just released and the analysis for Iowa has gotten worse. Please note that the analysis only includes precipitation up until 7 AM Tuesday, so the heavy rainfall events these past two days are not included! The most severe drought category "D4" was significantly expanded over Iowa with the coverage now the largest on record since the inception of the product in the year 2000. The featured chart presents a weekly time series of the category coverage. The plot starts in 2012 as that was the first occurrence of D4 in Iowa. Only 2012, 2022, and 2023 have seen such a drought category in the state.
