SYNOPSIS

26/929 AM.

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 today, and possibly again Friday. 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)

26/314 AM.

Not much change in the long term. Temperatures start to cool off on Sunday, with an earlier sea breeze arrival for coastal areas as offshore gradients trend onshore by afternoon, if not sooner.

The cooling trend starts to ramp up Monday and Tuesday, then likely 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 still continue to fluctuate from model run to model run. Majority of ensemble members suggest around 0.5 inches of rain, along with the AI models around that same ballpark.. Timing could be as early as late Monday night or as late as Wednesday, though the majority is still Tuesday.
