Several severe storms developed in a highly sheared environment. Instability was adequate enough to cause a few of the storms to become tornadic near Silver Lake, and around Forest Lake, and Scandia during the afternoon of Sunday, July 28th.
A storm survey found a total of six tornadoes. These surveys indicated an EF1 tornado formed near Silver Lake, and another between Forest Lake, north of Scandia, and into southern Chicago County.
The worst damage occurred along Bone Lake near Scandia, where very large trees were uprooted or blown down. Some of the trees caused significant damage to lake homes on Bone Lake.
