What happened

The episode as NWS PAH wrote it up.

Widespread dense fog formed, mainly from Evansville north and west. The fog formed over snow-covered ground. Clear skies and light winds allowed temperatures to cool quickly over the snowpack, and visibilities fell below one-quarter mile just before sunrise. The fog burned off by late morning.

What forecasters said that day
