Skies will be clear the next several days except for some high clouds at times. High temperatures will climb each day through Saturday, with temperatures warming into the 70s and 80s. Locally breezy Santa Ana winds are likely late tonight into the weekend.

A typical La Nina pattern is in full effect across southwest California with semi-perminent high pressure along the eastern Pacific deflecting storms well north into Canada.
For the rest of the week, moderate offshore flow combined with a warm air mass will push high temperatures to near or possibly above daily records. Local temperature guidance suggests highs in the mid 80s across LA/Ventura County coast and valleys, with a about a 10% chance of reaching 90 on the warmest days which are expected to be Friday and Saturday. Very warm for the Central Coast as well, especially away from the immediate coast with highs in the 70s to low 80s which would be close to records there as well. Overall, highs will be 13-18 degrees above normal.
Breezy Santa Ana winds have already returned today across mainly the mountain and foothill regions of LA/Ventura Counties as well as the Santa Lucia Mountains. Some strengthening is expected tonight as there is slightly stronger and better alignment of northeast winds aloft, but at best this looks like a low end wind advisory for those same areas. May need another one for late Thursday night into Friday as well.
(Sun-Wed), 28/211 PM.
Overall the warm and dry pattern will continue through next week but with a little dip in temperatures Sunday and Monday as a weak system moves into the Pac NW and gradients turn lightly onshore. But even during this period temperatures will still be at least 3-6 degrees above normal.
The rest of next week will be very warm, especially Tuesday through Thursday, with the potential for even warmer temperatures than this week depending on the track of a low pressure system dropping through the Great Basin. Some solutions swing the low back towards southeast California next Wednesday which could force some cold air advection into the area, but more solutions favor a farther east trajectory which would result in warmer temps locally. Either way, no chances for any rain next week and likely through at least the first 10 days of February.

Around 17Z at KLAX, there was a surface-based inversion. The top of the inversion was at 800 ft with a temp of 17 deg C.
Hi confidence in the 18Z TAFs. VFR conditions are expected through the period, except for a low chance (20%) of VLIFR conditions at KPRB after 12Z tonight.
KLAX, Hi confidence in the 18Z TAF. VFR conditions are expected through the period. Any easterly winds should remain less than 7 knots.
KBUR, Hi confidence in the 18Z TAF. VFR conditions are expected through the period.

Generally Moderate to high confidence in the current forecast.
For the waters south and west of the Channel Islands, there is a high- to- likely (50-70 percent) chance of Small Craft Advisory (SCA) level winds through Thursday night. Conds should be below SCA levels for the northern inner and outer waters during the period. For Friday through Mon night, conds will largely remain below SCA levels, except for an increase in seas to SCA levels by later Sun or Sun night.
Inside the southern California bight, wind and seas will very likely remain below SCA levels through this evening, then areas of north to northeast winds to SCA levels are expected for the nearshore coastal waters off the Ventura County Coast to Malibu each night and morning through Thursday night. Conds should then be below SCA levels Fri through Mon night.
