Marine clouds near the coast have been stubborn over the last couple days, some better wind direction and strength will help to produce much better clearing over the next couple days.
Offshore winds Wednesday morning won't be very strong, likely under 15mph in most locations but that along with a turn to the NW and an increase in speed to 15-25mph in the afternoon will be the mechanism for better clearing. It should produce warmer temperatures at the coastal valleys and beaches.
In northern California a cold front will slice thru and produce a few showers Wednesday night into Thursday with no rain this far south. The impact of this frontal passage will actually be to crank up the winds. At first out of the NE up to 20mph early Thursday then again turning around the to NW and picking up at the coast to 15-30mph. Again the increased sunshine and high pressure will keep temperatures up.
The larger increase in temperatures will take place on Saturday as a high pressure ridge starts to build. Sunday through Tuesday (at least) the ridge will fuel very warm temps, likely over 100 inland. Coastal valleys will likely also be well into the 90s.
