What happened

The episode as NWS AMA wrote it up.

Clear skies and light winds across the Oklahoma Panhandle allowed strong radiational cooling during the early morning hours of the 10th. The strong cooling coupled with low level moisture in place across the panhandle to cause the development of dense fog. The dense fog caused traffic issues during the morning commute across the panhandle. By 11 am, low level mixing increased and dissipated the dense fog. The following towns dropped to a quarter mile or less visibility across the Oklahoma Panhandle: Guymon (Texas County) and Beaver (Beaver County).
