This along with the marine layer clouds will create mostly cloudy skies at times with limited clearing. Maybe a reverse clearing trend, with nice clearing over the coast but not for long.

The second upper level low will arrive late Wednesday into Thursday. This will bring a westerly track , allowing for drizzle and light rain into Ventura County. Cooler air aloft will weaken the inversion which will allow for a break up in clouds and more afternoon sunshine.

As a weak upper ridge develops into Friday, this will improve conditions slightly. Although onshore flow will remain strong causing for coastal areas to remain cool under the marine layer influence. This will repeat into Saturday, with potential for slight warming.

On Sunday a full latitude through will move along the west coast bringing in a decent amount of moisture. This could bring light rain showers mainly to areas north of Point Conception. At this time the system is expected to fizzle out by the time it reaches Ventura County bringing little to no activity.
