Baron Tornado Index (BTI):
Revolutionary Tornado Detection

The Baron Tornado Index signaled probable tornadoes in a prolific tornadic supercell for the majority of its 160-mile path.

	At 4:33pm, a Baron Shear SCIT (left) indicated a value of 7.
	An EF-4 tornado from the same cell was later reported in Atkins near I-40 and Highway 105 at 5:02pm, causing four fatalities. The NWS later determined that the tornado's path was 123 miles long, the longest in Arkansas since 1950.
