We have returned to a more typical early summer/early July weather pattern around California's Central and South Coasts with the marine layer pushing onshore during the overnight hours. We can expect another round of low clouds and fog along the coasts tonight and tomorrow morning, but it will be more extensive for some of our coastal valleys. Lows will stay in the mild 50s and lower 60s by Saturday morning.
A ridge of high pressure will be in control of the weather of the western United States, and coastal California will be on the western edge of that ridge. A trough of low pressure will begin deepening over the eastern Pacific this weekend, and will continue to get stronger and influence our weather going forward. Highs will be range from the 60s on the coast to the lower 90s in our inland valleys, and clouds may be an issue with fireworks Saturday night.
The trough over the eastern Pacific will get deeper and move onshore next week, and it will bring even more low clouds and fog with it. Coastal communities will struggle to get out of the gray at times, especially by next Wednesday and Thursday. By this time next week another ridge of high pressure will begin to build over the coast, clearing our sky a bit. Highs will stay in the seasonable 60s on the coast, with 70 and 80s further inland.
