The path drawn at its surveyed width of 25 yards (0.01 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

An EF-0 tornado with estimated peak wind 80 mph, 0.92 mile path length, and path width of 25 yards moved through portions of Owen County. Survey damage suggests the tornado began west of North Humpty Dumpty Road south of Patricksburg, IN just before.

The wider storm

The 21st late day brought a quickly-evolving set-up featuring an increasingly moist column supported by an approaching Middle Mississippi Valley upper short wave trough, strengthening flow amid a warm frontal zone draped over the local central Indiana region providing 35-50KT of effective wind shear, and advection of higher low-level dewpoints with daytime heating which provided sufficient destabilization. Severe rotating supercells tracked across Illinois into southern central Indiana as they aligned into a Mesoscale Convective Vortex (MCV).

Wind damage occurred within nine central Indiana zones and as far east as Brown County, five (mainly EF-0) tornadoes were focused in Owen County and points south and west, while the region's farthest southwestern counties experienced scattered flash flooding following downpours from multiple supercells. A final EF-0 torando and flash flooding also occurred in Bartholomew County. This Bartholomew County EF-0 was Indiana's 63rd tornado in 2026...a new yearly state tornado record (73 events) was set later in the evening, with 74 tallied by the end of June 21st.

Began near Patricksburg (39.2970, -86.9637).
