Event narrative

Visibility below a quarter mile was reported in Lemoore.

Wider weather episode

Although an upper trough with a fairly strong cold front approached the area overnight, skies remained mainly clear and winds remained fairly light across the San Joaquin Valley until daybreak on February 2 which allowed for dense fog to form across much of the San Joaquin Valley. The fog persisted until the cold front arrived later in the morning which completely mixed out the fog by midday.
