2020-01-24 · Western San Joaquin Valley, California

Event narrative

Visibility below a quarter mile was reported in Lemoore. Several school districts either opened late or delayed or cancelled bus service.

Wider weather episode

High pressure continued to strengthen over the area on January 24, although some high clouds pushed through the area, light winds and inversion conditions allowed for an areas of dense fog to form in the center of the San Joaquin Valley north of Kern County where low level moisture has persisted. The fog reduced visibility to less than an eighth of a mile at several locations, and resulted in several school districts either opening late or delaying or cancelling bus service as it persisted until late morning when it lifted into a low cloud deck. The low stratus deck slowly dissipated during the afternoon. The fog also contributed to two multi-vehicle accidents near Caruthers.
