What happened

The episode as NWS GJT wrote it up.

Following multiple days of rain and snow showers, drier northwesterly flow on the backside of a shortwave trough brought clearer skies on the evening of February 13 into the morning of February 14. With ample surface moisture still in place from the prior days' precipitation and strong radiational cooling from clear skies, dense fog developed across many valleys.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
