What happened

The episode as NWS HNX wrote it up.

Moisture from the rains saturated the airmass near the San Joaquin Valley floor, bringing the first episodes of Tule Fog of the winter. Of the four days (February 12th-15th) with locally dense fog, the 13th saw the most fog. Even so, the fog was mostly patchy and formed mainly in the Madera-Atwater and Selma-Hanford/Visalia areas. Dense fog also formed near daybreak along the Highway 41 corridor in western Fresno County and the Highway 198 corridor from Lemoore to Hanford.

In addition to the low-level moisture, fog development was aided by a stable airmass due to an upper-level ridge over the central California interior. This high pressure aloft also brought a warming trend, with above-normal temperatures from February 12th through the 17th.
