The episode as NWS HNX wrote it up.
High pressure rebuild off the California coast on Thanksgiving morning. This kept skies mainly clear across the San Joaquin Valley overnight. With light winds and inversion conditions present, areas of dense fog formed in the center portion of the valley once again impacting travel mainly along the SR 99 corridor from Visalia to Turlock. The fog dissipated by late morning giving way to a sunny afternoon across the valley.
