What happened

The episode as NWS PAH wrote it up.

Dense fog reduced visibility to one-quarter mile or less across parts of southeast Missouri, mainly along and south of a Poplar Bluff to Sikeston line. The fog formed shortly after sunset, immediately after skies cleared out. The combination of clear skies and light winds promoted the rapid development of shallow dense fog.
