Clearing skies and diminished winds behind a cold front during the early morning of January 17 allowed for some radiational fog to form in the San Joaquin Valley mainly between Interstate 5 and State Route 99 north of Kern County. The fog reduced visibility below a quarter mile for a few hours in the Merced area and along the State Route 198 corridor between Lemoore and Visalia. The fog lifted into a low cloud deck by late morning and dissipated during the afternoon.
