The episode as NWS MPX wrote it up.
A dome of high pressure built across the Upper Midwest during the late weekend of June 19th. Heat indices surpassed 100 degrees in several areas of the Twin Cities, and across west central Minnesota where the index approached 105 degrees for several hours on Sunday. The highest heat index value was 105 degrees at Granite Falls Sunday afternoon, with 104 degrees at the Crystal airport. Heat indices were actually higher on Monday due to limited cooling the night before and lasted longer in the metro area due to the heat island effect. The highest heat index values outside the metro area was 108 degrees at Redwood Falls. In the Twin Cities, Crystal airport once again was the highest with 108 degrees by late afternoon. There were other higher heat indices across the area, but these were uncontrolled private weather stations that aren't certified as official.
