On the evening of June 17, 1978, a small outbreak of eight tornadoes occurred between the Great Plains and Midwest regions of the United States. The highest-rated twister occurred in Wisconsin at F2 strength, with the remaining seven only inflicting F0-F1 damage in Michigan, Iowa, and Kansas. These statistical values accepted at face value would not suggest the possibility of a historic tragedy having occurred on this day. However, just off the shores of Pomona Lake in the state of Kansas, unlikely circumstances led to one of the most bizarre catastrophes. In its wake, a glorious spectacle lay tarnished, sixteen lives lost, and much more stunned with heartache and confusion.
During the morning hours of January 11, 1951, a squall line pushed across the San Franciso Bay area. The storms produced millions of dollars in damage as straight-line winds and tornadoes ripped through the region. Per the Storm Prediction Center (SPC) and National Climatic Data Center (NCDC) databases, one twister occurred on this day, an F2 in Sunnyvale. Thomas Grazulis in Significant Tornadoes lists two tornadoes, the Sunnyvale F2, as well as an F2 at San Jose. Upon doing research, we were able to definitively confirm two additional tornadoes, one that moved through parts of Marin and Sonoma counties and a weak one in Contra Cosa County. It is likely that other funnels occurred, though reports in the newspapers were not detailed enough to confirm others.

The 2011 Super Outbreak reached far beyond populated areas into the wilderness. Deep in the Great Smoky Mountains, five tornadoes occurred on April 27 within five hours. These twisters repeatedly pounded areas of the Cherokee National Forest and Great Smoky Mountains National Park, tearing large chunks of forest from mountains and shutting down trails for months.

I chose this event because it hit within a large city, Detroit, MI. As I started delving into the data, I became even more intrigued because right of the bat there is a discrepancy in the rating. Officially, the SPC Database lists the rating of this tornado as an F3. Thomas Grazulis in Significant Tornadoes believes the damage was more in the F1 range.
