Dense Fog in Eastern Uinta Basin, Utah

Widespread dense fog developed within the eastern Uinta basin during the morning of February 13. The KVEL ASOS at the Vernal Regional Airport reported almost two hours of 1/4-mile visibility due to dense fog. No reports of injuries, damages, or fatalities were received.

Relatively clear early-day skies on February 12 led to isolated convection with rain and snow showers across portions of eastern Utah. Some valleys were already saturated or near-saturated due to periods of precipitation over the prior days. As such, in spite of dense cloud cover lingering overnight and lacking radiational cooling, saturated surface conditions paired with weakening winds were capable of producing areas of dense fog on the morning on February 13.
