What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

NWS meteorologists determined a tornado touched down in the city of Midfield with a fairly brief, but wide damage path, with a core of concentrated significant damage. Initial damage was found near Cairo Avenue, where trees were toppled and snapped. This damage was rated at EF-1 intensity. The tornado then tracked northeast, where EF-2 damage occurred along Jefferson Avenue SW and Park Avenue SW, bounded by 50th Street to the south and 49th Street to the north. Here, residential homes were heavily damaged, with two homes flattened. Many trees were also snapped and uprooted. A rapid decline in intensity was observed as the tornado moved northeast, with EF-1 and EF-0 damage consisting of roof damage and snapped/uprooted trees stretching from Grasselli Avenue SW to Carver Avenue SW and 45th Street SW. There were a total of about 50 homes impacted, with approximately 15 that were uninhabitable.
