A shortwave trough brought rain and snowfall to the Abajo mountains and surrounding areas on November 23. Overnight, the trough moved out of the region. A weak pressure gradient made for calmer winds, and a drying mid-level atmosphere cleared skies. With the recent precipitation though, low-level moisture remained pooled over southeastern Utah leading to the development of patchy dense fog.
