What happened
The episode as NWS OUN wrote it up.
A series of upper level low pressure centers moved over the southern plains during the first couple of days of May. One low pressure center moved east along the Red River during the afternoon of the 3rd. By afternoon, surface heating combined with several boundaries left over from previous showers and thunderstorms, improving instability, and ample Gulf moisture allowing numerous showers and thunderstorms to develop. Several of thunderstorms became severe, producing large hail and very heavy rain. The largest hail occurred in Love county, where hail up to golf ball size was reported.
