Midwest Drought Early Warning System

Conditions for the week of August 9 – 15

Rainfall helped in some areas, but lack of adequate precipitation worsened conditions in others. Abnormal dryness (D0) was introduced in northeastern Ohio, where rainfall over the past month has been less than 20% of average. Short-term dryness is now evident in part of central to west central Indiana where adequate rainfall is lacking. In two small regions of southern Iowa, dryness over the past two to four months warranted degradation to extreme drought (D3). Extreme drought conditions were also expanded in the south. Moderate drought (D1) expanded in southwestern and far northeastern Iowa, reflecting dryness over the past four months or so.  However, rainfall in excess of two inches over the past week did help to improve conditions in the northwestern part of the state. Moderate drought now encompasses all of Marshall County in northwestern Minnesota, where low streamflows are reported and fire danger is rated high.
