Before the main afternoon severe weather, a small cluster of storms produced some dime size hail near Willmar, Minnesota, along with severe wind gusts in the mid morning hours.
During the afternoon of Sunday July 10th, a cluster of thunderstorms developed along a southwest to northeast surface trough, near the Minnesota, North Dakota, and South Dakota border.
Strong surface heating with temperatures in the mid to upper 80s, combined with high humidity levels to produce strong to severe thunderstorms.
With effective bulk wind shear values around 35 knots, a few supercells developed west of Alexandria, Minnesota. As the cluster of storms continued to develop, they moved east and southeast along the strongest temperature and moisture gradient axis.  This resulted in several funnel cloud reports, one brief tornado touchdown, and numerous reports of large hail, and damaging wind through the early evening hours across mainly west-central Minnesota, and a small portion of southwest and central Minnesota, before the storms decreased to mainly heavy rainfall reports.
Some of the storms across Pope and Swift Counties of west-central Minnesota, merged and trained across the same areas for about two to three hours. This allowed for isolated three to four inches rainfall totals near Starbuck where flash flooding was reported.
