A batch of high pressure moving westward through Sunday will bring a warming trend to southwest California, with well above normal temps on Saturday and Sunday in San Luis Obispo County.
That high pressure system weakens early into next week, bringing cooler temperatures to most of the area and a return of coastal clouds and fog by mid week.
The marine layer will be slower to clear Friday. Almost all beaches should clear by the early afternoon.
A strong upper level high over Arizona and New Mexico will expand over California through Sunday, bringing warming and drying to the area.
Temperatures could reach six to 12 degrees higher than normal.
The heat will confine low clouds, making for some dense fog in the Santa Barbara coast.
Heat advisories are expected in SLO County's interior valleys, mountains and the LA County valleys through the weekend.
High temperatures are expected to fall each day Monday through Wednesday with the biggest drop occurring Tuesday.
