Two rounds of strong to severe thunderstorms occurred across Burnett, Washburn, Sawyer, and Price counties in northwest Wisconsin. A cold front moved through the area in the morning and triggered strong to severe storms, which produced hail up to dime size, wind damage, and heavy rain that contributed to flash flooding. The front stalled across the region by afternoon and produced more strong to severe thunderstorms. The thunderstorms produced hail from the size of peas to nickels, wind damage, and heavy rain that contributed to flash flooding. Several roads were flooded, including culvert washouts along with downed power lines. Disaster declarations due to the flooding were issued for the town of Emery in Price County, Sawyer County and the Lac Courte Oreilles Tribe. In Price County, the total damage estimate from Wisconsin Emergency Management was $562,000. In Sawyer County, the total damage estimate was $504,000.
