Overview
A multi-faceted storm system moved across the region June 8-9, 2020, producing 2 rounds of severe weather in different locations, as well as areas of heavy rainfall. The prolonged nature of this event was driven by Tropical Depression Cristobal, which lifted north along the Mississippi River Valley on these 2 days, before becoming extra-tropical and turned northeast into the Great Lakes. While our area did not experience rainfall directly associated with Cristobal, this south-north moving tropical system blocked the weather pattern from progressing, resulting in several hours of storms tracking through areas west of Interstate 29 from the evening of June 8 through the afternoon of June 9. By late in the day on June 9, the remnants of the tropical system has begun to weaken, allowing stronger storms and locally heavy rainfall to work eastward into far southeast South Dakota and northwest Iowa. |
Wind & Hail:
Strong winds damaged many trees, power lines, and out-buildings across the area. The largest hail was tennis-ball sized with the strong storms on Monday evening, June 8th.
