EF0 tornado in Bartholomew County, Indiana

An EF-0 tornado with 0.49 miles path length, and path width of 85 yards moved through portions of Bartholomew County. The tornado began east of US Highway 31 and continued northeast through a tree line and into a corn field. A convergent wind pattern was noted. Peak winds were 85 mph.

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.
