What happened

The episode as NWS AMA wrote it up.

The Oklahoma Panhandle saw a round of severe convection during the late evening hours of the 30th. Northwest flow aloft allowed the passage of an upper level shortwave trough which combined with a sufficiently moist and unstable atmosphere to help initiate this convection. The convection developed along the leading edge of a southward moving cold front across southeast Colorado and northeastern New Mexico. These storms then moved into the Oklahoma Panhandle during the evening hours. Some of the storms became severe, with damaging winds as the primary hazard. Shortly before midnight on the 1st, the shortwave moved sufficiently east to bring an end to the severe threat across the Oklahoma Panhandle.

What forecasters said that day
