Overview

During the late afternoon and early evening of July 19, 2019, thunderstorms developed over north central Minnesota and quickly spread eastward and southeastward. One supercell thunderstorm moved through Pine County in Minnesota and produced significant wind and hail damage, especially near the Rock Creek area. This storm continued to move over far southern portions of Burnett County producing damaging winds. Another supercell thunderstorm moved from Douglas County southeast through Sawyer and through Price Counties in northwest Wisconsin producing significant wind and hail damage. Behind this supercell, a line of storms developed producing strong winds as things wrapped up during the evening. We extend our thanks to Pine and Sawyer County Emergency Management and Wisconsin Emergency Management for their considerable assistance in documenting and assessing this weather event.
