Wider weather episode

Although the fog layer lifted into a stratus deck during the afternoon of December 24 across much of the San Joaquin Valley, it lowered back down to the valley floor in Merced County during the evening and further south overnight. This resulted in widespread dense fog prevailing across the San Joaquin Valley during Christmas morning. The fog lifted into a low cloud deck across most of the valley by early afternoon.
