In the early morning hours on Friday June 11th 2021 (3:00am) a line of severe thunderstorms moved into the Devils Lake Basin, stretching down toward the James River Valley. These storms where moving rather quickly toward the east around 50-55mph. Warnings were issued from the international border toward South Dakota, with damaging winds being the primary threat.

Heavy rainfall and numerous wind reports along and west of the Red River came in, with isolated hail reports of quarter and half dollar being reported in Cass County. Highest wind reports were in Steele County, with 80-85 mph being measured through NDAWN or local spotters. As the storms moved into the Red River Valley they began to weaken and become unorganized. Slowly storms dissipated as they moved into lake country in Minnesota. Rainfall estimates across eastern North Dakota, NW Minnesota, and West Central Minnesota ranged from 0.5 inches to just under 2.0 inches. Any additional reports will be added as needed.
