Thunderstorms that originally developed across the Arrowhead of Minnesota early Wednesday morning, August 17th, created a boundary farther southward across east-central Minnesota. This boundary, with daytime heating leading to more instability, caused additional thunderstorms to develop. Due to weak winds aloft, these storms drifted southward but continued to redevelop on the west side. This led to storms training over the same areas from Mora, southward to the eastern portion of the Twin Cities
