Dense Fog in Eastern Uinta Basin, Utah

Areas of dense fog developed within the Uinta Basin on the morning of January 3. The KVEL ASOS at the Vernal Regional Airport reported two periods of 1/4 mile visibility or less, one in the morning and one in the afternoon, from freezing fog. No reports of injuries, damages, or fatalities were received.

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.
