A warm weather pattern will continue through the next week over much of the area, but some cooling will develop for late week a high pressure aloft weakens. A shallow marine layer depth will develop for the end of the week and could bring dense fog to the coastal areas. A warming trend will develop again for early next week.
(tdy-Sat), 10/1247 PM.
Another warm day is occurring across southwestern California this afternoon. Daytime high temperatures are well above normal, so far, hovering close to record daily high values. Clear skies remain prevalent across the area as a strong blocking ridge of high pressure aloft continue to drive a warmer and drier weather pattern.
A cooling trend should develop over the coming days as a weak trough will replace the ridge. The ridge axis should move over the region tonight or early Thursday morning and high pressure aloft should start to break down. Temperatures will likely remain above normal through the period as 500 mb heights do not drop enough. A return of onshore flow late this week should bring a return of low clouds and fog. A shallow marine layer depth looks likely to develop across the coast and dense fog could become an issue as we move forward into Friday and Saturday.
(Sun-Wed), 10/109 PM.
Ridging aloft will restablish early next week and likely strengthen through the week. A warming and drying trend will restablish early next week with temperatures likely going well above normal again by the middle of next week. Offshore flow is likely to redevelop again, although not as strongly as it was this week.

Localized Small Craft Advisory wind gusts are likely across the far NW portion of PZZ670 through this evening. Otherwise, high confidence in fairly calm conditions and lowering seas through this weekend. SCA level winds are likely to return across the Outer Waters south of Point Conception next week.
Some dense fog will form in the coastal waters by Thursday or Friday, but low confidence on when and where.
