Some of the driest conditions in the state currently can be found over southeastern Iowa. The featured chart looks at the arridity index calculated over 30, 60, and 90 trailing day periods for this year for an areal averaged value representing southeastern Iowa climate district. This index combines temperature and precipitation departures to access water stress. Since early June, the chart shows the increasing stress for this area. There are more chances of rain in the forecast, but the best chances are over northern Iowa.
