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.
(tdy-Sat), 26/314 AM.
Low clouds and patchy fog have pushed into the valleys of Ventura overnight, but actually retreated back towards the coast of L.A. thanks to higher level clouds streaming over the region. While the marine layer clouds will likely continue to retreat back towards the ocean this morning, these higher level clouds will be persistent through the day, bringing partly cloudy skies to southwest California.
High temperatures today will be in the 70s to 80s, with the interior/warmest valleys warming up a tiny bit and pushing into the 90s. Thanks to weak high pressure aloft building into the region this weekend, and light offshore flow, the region will see some warming Friday and Saturday, peaking Saturday, and pushing temperatures into the 80s and 90s. These temperatures will go from about 5 to 15 degrees above normal today, to 10 to 20 degrees above normal Friday/Saturday.
Increasing northerly winds are expected across the mountains and parts of the Santa Barbara County, however not anticipating them to quite reach advisory levels. These winds will still produce some downslope warming that will contribute to the warming trend this weekend. Based on the record highs for Saturday there is definitely a chance of some broken temperature records.
(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.

At 1150Z at KLAX, the marine layer was 1100 feet deep. The top of the inversion was at 3600 feet with a temperature of 20 C.
High confidence TAFs for KPRB, KPMD, & KWJF.
Low to Moderate confidence in remaining TAFs through 17Z Thu, and after 06Z Fri. Timing of CIG/VSBY restrictions may be off +/- 2 hours. Cig hgt could be off by +/- 200 ft at any point. High clouds disrupting the marine layer may cause cigs to scatter and reform multiple times through 17Z.
There is a 30% chance of V/LIFR conditions 10Z-15Z at KSMX.
KLAX, Low to moderate confidence in TAF through 17Z, and after 06Z Fri. Otherwise, high confidence in TAF. Cigs may scatter and reform multiple times through 17Z. Expecting CIGs 005-010 with VSBYs 3-5SM. Low clouds could return as early as 00Z Fri. No significant east wind component is expected.
KBUR, Low to moderate confidence in TAF through 17Z, then high confidence. CIGs 005-010 with VSBYs 3-5SM likely through 17Z, but may scatter and reform multiple times through 17Z.

High confidence in Small Craft Advisory (SCA) winds and steep seas continuing through this evening over the offshore waters from the Central Coast down to San Nicolas Island. Howvere, for the northern outer waters north of Point Sal, local GALE FORCE gusts will continue through mid-morning. Conditions will likely weaken quickly and significantly on Friday, with moderate to high confidence of generally below SCA levels conditions Friday night through Monday night.
Moderate to high confidence in the rest of the waters being below SCA levels through Monday night.
