There is an upper level high pressure system over the desert SW. It'll be the main factor in the forecast for this week. As it expands west the inland highs will continue to cook. It'll be clear inland and away from the beaches, and the marine layer will be quite shallow under the increasing high pressure with the potential for patchy dense fog at beaches.

Winds are still lightly onshore.

Wednesday will likely be the warmest of this week as high pressure peaks.

Weak onshore flow will remain and the marine layer will be confined to the beaches by mid morning again Wednesday. Away from the cooling marine air temperature will be hot. High temperatures away from the coasts will end up 5 to 10 degrees above normal and will mostly range from 95 to 104 degrees.

Thursday will be similar to Wednesday with the high pressure feature beginning to move to the south east by the evening.

The Friday cool-down will be driven by a trough dropping into the Pacfic NW.

Saturday will be the coolest of the next week with coastal and valley high temperatures cooling to 3 to 5 degrees below normal. The interior will also cool to within a degree or two of normal.

Sunday should remain relatively cool as well.

Another large warm upper high is forecast to move back into the area beginning Monday and will kick off a warming trend that looks stronger than this week`s.
