What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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

A National Weather Service storm survey determined that an EF-1 tornado with maximum winds of 100 mph traveled along a 7 mile path. This tornado snapped tree trunks as it touched down south of I-44 just east of the Greene/Webster County line near the Wild Animal Safari and crossed the Interstate near Heritage Rd. Wind speeds were measured at 80 mph before an anemometer failed near the intersection of Cologna Rd and Whispering Oaks. The roof of a manufactured home was torn off and several trees uprooted at this location. After destroying a large outbuilding on Headwaters Dr, the tornado downed large branches as it lifted crossing State Highway J near Highway 38.

The wider storm

Multiple rounds of storms producing heavy rainfall, severe winds, hail and tornadoes moved across the Missouri Ozarks from May 20th and into the early morning hours of May 24th as upper level disturbances interacted with a slow moving but powerful storm system over the central Plains. Tornadoes occurred with each round, with the strongest and most numerous tornadoes occurring during the late afternoon and evening of the 22nd. On the anniversary of the Joplin Tornado off 2011, another tornado, rated EF-3 struck the north side of Joplin. This storm system eventually produced subsequent tornadoes in Golden City, Eldon and Jefferson City. Unfortunately there were three fatalities as a result of the tornado in Golden City. The cumulative rainfall caused areas of flash flooding with some flooding lingering across the region. Some locations in southeastern Kansas and southwestern Missouri reported in excess of 8 inches of rainfall over the 72 hour period. .

Began near Holman (37.2722, -93.0549).
