A strong and persistent 1,037 millibar Eastern Pacific High, centered about 1,600 miles northwest of the Central Coast, combined with a thermal low over the Central Valley, will continue to produce typical summer weather with clouds night and morning low seas and pockets of fog. and haze in coastal regions.
