The wider storm

High pressure set up across eastern Utah overnight from January 3 to 4, leading to clear skies and light winds. Pools of strong moisture remained within many valleys though from precipitation earlier in January. With this, cooling overnight temperatures led to a saturated near-surface environment and widespread dense fog.
