A moist and very unstable air mass was in place over eastern Oklahoma ahead of a dry line that approached the area during the afternoon. A warm layer of air aloft suppressed thunderstorm development until late in the evening. Thunderstorms that formed along and just ahead of the dry line over northeastern Oklahoma became severe with large hail and damaging straight-line wind. A second round of storms formed on a cold front that moved through the region during the overnight hours and a few of those storms also became severe with damaging wind gusts.
