A very unstable and moist airmass developed across the region during the afternoon and evening hours of May 26th.  Weak northerly flow aloft allowed for a weak disturbance to move southward out of central Arkansas during the afternoon. This in combination with a weak thermal boundary in the lower levels of the atmosphere proved to be the trigger for scattered to numerous showers and thunderstorms across the region.  Additional thunderstorm activity developed along remnant outflow boundaries and a few of these storms became severe.  Damaging wind gusts were the main threat of the afternoon and evening along with a few large hail reports.
