Daily Feature

Weeks of D0+
Date: 18 Jul 05:30 AM
Votes: Good: 10   Bad: 0 Abstain: 0

With only a small sliver of "D0" drought classification left in the state and that area receiving plenty of rainfall over the past week, it seems highly likely that the entire state will be free of any drought classification with today's US Drought Monitor update. This will be the first time free of even D0 drought since May 2020. The featured map presents a grid analysis of the percentage of weeks of at least D0 classification since 1 May 2020. Over this period, northwestern Iowa has seen the largest percentage of time with at least D0 classification. The near term forecast looks drier than we have been recently and pleasant temperatures.
