Skies cleared out and winds diminished following the passage of an upper through during the evening of January 3 allowing for patchy dense fog to form in parts of the San Joaquin Valley. The fog was most noticeable along SR 99 between Merced and Madera where travel was briefly impacted. The fog dissipated and mixed out by late morning on January 4.
