It has been very dry in parts of the Upper Midwest as the map below indicates. What could be a drought-busting rain will occur over part of the region next week. 
Colors on the map depict how short of rainfall each area

Going back further, here is the Palmer Drought Index for June:

Below is the forecasted rainfall for the next seven days.

NWS is forecasting a "moderate" risk of flash flooding from 2am Saturday through 7am Sunday.
