Numerous showers and thunderstorms covered Arkansas during the early morning hours on May 20, 2025.

These storms exited the region by mid-morning.

A brief lull in thunderstorm activity occurred from late morning until early afternoon. Gusty southwest winds aided in rapid atmospheric recovery with SBCAPE values greater than 2000 J/kg by mid-afternoon. In addition, dewpoints remained in the low 70s with bulk shear around 50 kts. Initially, storms were supercellular in nature and eventually formed into a line during the evening hours. Damaging winds and hail were common during this event, and a weak tornado occurred near Jackson, TN.
