High pressure is still in control of the West Coast weather pattern. This has produced warm inland temps and is also continuing to transport and trap some smoke and haze from numerous fires in the state. This produces the red skies in the night and morning with the thin gray/white haze filtering the afternoon sun.
At the coast we have some marine clouds and influence this too will continue much of this week.
Inland temps will be near 100 much of the week while coastal valleys in the 70s and 80s with beaches in the 60s and some low 70s. Afternoon conditions will feature onshore winds which will keep much of the coast mild.
High pressure should weaken a little into next week as a low-pressure system moves into far Northern California.
