Oklahoma City (OKC), by temperance of its enormous areal degree and area close to the core of "twister back street," has procured a standing throughout the years as one of the more cyclone inclined urban communities in the US. During the 1960s and 1970s, news and magazine articles now and again cited the times OKC has been struck by twisters; that number normally was during the 30s or lower 40s, depending on the extended period of distribution. The wellspring of the number in all likelihood was a neighborhood posting, kept on station at the Public Weather Help Figure Office (WSFO OKC). That rundown included 43 twisters starting around 1978. In a little while, record keeping stopped for reasons unknown and the current rundown was consigned to a binder that was lost among the developing masses of other records that gathered at the workplace.

In 1991, a venture was started to overhaul the rundown by adding ongoing cyclones (starting around 1978), approving existing sections, and looking for any others that could have been disregarded. This ended up being a considerable undertaking, because of multiple factors. One was the absence of solid hotspots for occasions that happened before 1950. The just promptly accessible information source before 1950, other than the neighborhood records on station at WSFO OKC, was Grazulis (1990). The assemblage by Grazulis includes all cyclones of F2 power or more noteworthy, and all executioner twisters, from 1880 through 1989. In this way there are no records on feeble twisters preceding 1950 (except if they ended up making it into the WSFO posting), and so the genuine number of cyclones presumably is a lot higher than the complete showed up at thus. After 1950, records were cross-checked utilizing Tempest Information and the extreme weather data set aggregated at the Tempest Forecast Center (SPC).
