Wider weather episode

Potent surface moisture lingered within Utah valleys on the morning of January 3 resulting from widespread rain and snow over the prior two days. A deep upper-level ridge moving overhead made way for clear skies though. With the resulting radiational cooling, morning and early afternoon surface conditions became saturated and supported widespread dense fog development.
