The episode as NWS GJT wrote it up.
A deep Pacific trough brought moist southwesterly flow to much of the western CONUS on January 1. A weak upper-level jet streak arrived in coincidence with the surge of moisture, prompting widespread precipitation in eastern Utah throughout the morning of the 1st. Strong cold air advection behind the storms rapidly saturated valleys, and areas of dense fog developed during the afternoon and lasting through the morning of January 2.
