The path drawn at its surveyed width of 50 yards (0.03 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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 confirmed an EF-0 tornado. Significant damage to a barn occurred near the starting point of the tornado along Soda Creek Road just east of Ash Street, throwing portions of the structure northeast, southeast and south. A pole barn east northeast of the barn was completely destroyed with posts, sunk three feet into the ground, lifted out and thrown to the east northeast. From this location intermittent tree damage, some of which in a cyclonic manner, occurred before the tornado destroyed another 20x40 pole barn and uprooted a three foot diameter walnut tree at a farm on New Hope Road. The pole barn was rolled to the southeast before the tornado moved into a field east of New Hope Road where a few additional trees were snapped or uprooted before the tornado dissipated. Maximum wind speeds were estimated at 80 mph.

The wider storm

Very moist and unstable conditions developed over the Missouri Ozarks ahead of an intense low pressure system over the southern Plains. Widespread severe storms developed over Oklahoma and eastern Kansas during the early morning hours and tracked eastward into the Springfield county warning area during the afternoon and evening. Very heavy rainfall, hail to tennis ball size, damaging winds in excess of 70 mph and 27 tornadoes occurred with this system as storms tracked repeatedly over the region. Four injuries were reported as a result of severe storms. One injury was near Mountain Grove and three were in southeastern Greene County were an EF-2 Tornado tracked. The resulting rainfall led to widespread flash flooding, which continued into the morning of May 1st, on head water streams and low water crossings. One live was lost when a camper along Hunter Creek in Douglas County drowned as the campground flooded.

Began near Louisburg (37.7205, -93.1210).
