June 2014 was a very wet and cool month across most of the region, especially across southeast South Dakota, southwest Minnesota, and northwest Iowa.  Rainfall amounts across central and northeast South Dakota as well as west central Minnesota ranged from 3 to almost 10 inches.  Rainfall amounts across southeast South Dakota, southwest Minnesota, and northwest Iowa ranged from 10 to 16 inches with Sioux Falls experiencing their wettest June on record with 13.70 inches. These rainfall amounts were anywhere from 150 to over 300 percent of normal June precipitation.  As a result, widespread flooding and damage occurred southeast in the region. The charts below show these astounding amounts.  In our region, the 9.89 inches at Timber Lake was the most June precipitation on record.  The 8.67 inches at Sisseton was the second wettest June with the 7.91 inches at Mobridge tying for the third wettest June on record.  Wheaton had their sixth wettest June on record with 8.04 inches.  Both Aberdeen and Kennebec finished the month just below normal for precipitation.  The cool trend continued across the region with most locations from 1 to 3 degrees below normal.  Pierre had their tenth coolest June on record.  Kennebec was our only location to get above 90 degrees for the month.
