Classic-style hook echo of the F5 1999 Bridge Creek-Moore tornado.. A hook echo is a pendant or hook-shaped weather radar signature as part of some supercell thunderstorms.It is found in the lower portions of a storm as air and precipitation flow into a mesocyclone, resulting in a curved feature of reflectivity.

An early-season tornado outbreak impacted the Southeastern United States on January 12, 2023. The result of a mid-level trough moving through, moisture and the presence of a strong low-level jet aided in the development of numerous severe and tornadic thunderstorms.

A PX-1000 transportable radar unit operated by University of Oklahoma's Advanced Radar Research Center was used to observe the path of the tornado through Moore, with researchers detailing a "loop" in the path near the Moore Medical Center as a "failed occlusion". [37] EF3 May 28, 2013: Bennington, Kansas — — 264 mph (425 km/h)
Animated radar loop (left, storm-relative velocity; right, reflectivity) of the nearly stationary supercell thunderstorm that spawned the EF3 tornado from 5:36–7:33 p.m. CDT (2236–0033 UTC). A large, very slow-moving, and erratic tornado remained on the ground for just over an hour as it executed a cyclonic loop in Ottawa County south of ...
