Two rounds of storms worked through the Twin Cities on June 21st. The first complex of thunderstorms moved through early in the morning bringing heavy rain, strong winds, and vivid lightning. However, a much smaller cluster of thunderstorms in the evening would prove to do far more damage in the Twin Cities.
Above is the radar image of the cluster of severe storms that moved through the Twin Cities between about 7:30 to 9:30 pm in the evening of June 21st. In South Dakota this was a much large complex that produced damaging wind and even a few tornadoes. However, it decreased in size as it moved through Minnesota, but its intensity did not within that cluster of storms that unfortunately went through a major metropolitan area. Below is a look at the storm reports from the 21st. You can see a bulls-eye of blue right over the Twin Cities showing many wind reports.
Winds with the storm gusted over 60 mph and the rain was torrential. Many locations picked up a good 1-3” in a very short amount of time. That lead to some street flooding not only in the Twin Cities but parts of Western Wisconsin as this storm moved east. Hudson was hit hard by rain, and it lead to flash flooding. Here’s a video sent into us from viewer Angela of flooding on Main St. in Hudson. Eau Claire, Menomonie, and Altoona, among other places in the Chippewa Valley also saw flash flooding during the evening of the 21st.
The wind damage was worse for the Twin Cities then across Western Wisconsin. Many trees and power lines came down as a result of the winds. Soils had been fairly saturated due to recent rains. That makes the soils fairly loose and easy for trees to get uprooted when there are strong winds. Below are some pictures from KARE 11 of some of the damage. The second image is from Robbinsdale, MN where a big sink hole opened up in the middle of the road due to all the water.
Hundreds of thousands of people were without power in the Twin Cities as a result of the storms that moved through. It’s been a slow process to get power restored. My parents are still without power, and it sounds like it could be a couple more days. As of Sunday, June 23rd, 122,000 customers of Xcel Energy are in the dark. The company says more than 400 crews and 1,000 linemen are helping in the restoration effort. They hope to have most people back up in running by Wednesday, June 26th.
