SYNOPSIS

25/709 PM.

Temperatures will remain above normal across all valleys and interior locations through this weekend. A persistent marine layer will keep temperatures on the cooler side for coastal areas south of Point Conception through at least Thursday. A warming trend Friday through the weekend will push temperatures to 10 to 20 degrees above normal. Cooler conditions are likely early next week with rain possible by Tuesday or Wednesday.

LONG TERM (SUN-WED)

25/201 PM.

One last hot day Sunday, though likely with an earlier sea breeze arrival for coastal areas as offshore gradients trend onshore by afternoon, if not sooner.

A cooling trend will begin in earnest Monday and continue through all of next week. Still looking at a high probability of rain locally, roughly a 60 to 80% chance, though timing and amounts are fluctuating. The AI models that for several days were leading the charge on this next system have lowered amounts quite a bit and now are mostly under a half inch across the area. Timing could be as early as late Monday night or as late as Wednesday, though the majority is still Tuesday.
