Thunderstorm Wind in McIntosh County, North Dakota

Three to five inch tree limbs were blown down.

A low pressure system over west-central South Dakota lifted a warm front into far southern North Dakota, with thunderstorms developing along and ahead of the front. This was in an area of enhanced instability and strong deep layer shear. Some of the thunderstorms became severe with the main threat being large hail, though a few produced damaging wind gusts. In addition, one storm produced a tornado in Adams County. The tornado touched down in an open field east of Bucyrus and impacted no structures. There was no damage to evaluate and so by National Weather Service policy the tornado is rated EF Unknown. The largest hail reported was the size of golf balls and fell in Emmons County. The strongest reported wind gust was 60 mph and occurred in Adams County.
