Wider weather episode

Areas of dense fog reformed in the San Joaquin Valley during the evening of December 21. The fog was responsible for a two vehicle accident near Porterville in which the driver of one of the vehicles was killed during the early morning of December 22. The fog lifted into a low cloud deck by late morning and dissipated by early afternoon as a low pressure system moving through the Pacific Northwest provided for some mixing.
