Cooler weather is expected over the weekend with scattered light showers, mainly on Saturday. Dry weather is then expected for most areas Sunday and Monday. Below normal temperatures will continue through the middle of next week with another weak storm possible around late Tuesday or Wednesday.
(Fri-Mon), 24/821 PM.
***UPDATE***
For the immediate short term, the only issue of note is a potential for stratus clouds along the Central Coast and LA Basin. Only moderate confidence that stratus clouds (with ceilings between 2000 to 3000 feet) will occur. A storm system approaching the area may cause mid to upper clouds to increase enough to disrupt stratus formation.
The storm system is fairly weak and the impacts will be minimal. Light scattered showers will affect portions of the area, with the highest amounts over the mountains, especially the San Gabriels. Rain chances will extend from Saturday afternoon through Sunday morning, mostly Saturday evening and night. Most areas will see rainfall totals under 0.10 inch, except for the mountains where 0.20 to 0.30 inch totals are possible. Westerly winds will cause downsloping across the Transverse Range, so expect to see lower rainfall from SE Santa Barbara County to western LA County.
Saturday afternoon should see gusty onshore winds (southwest to west) increase through the passes and canyons of the San Gabriels into the Antelope Valley. Gusts up to 40 mph are expected, with locally stronger gusts to 45 mph possible near Lake Palmdale. High temperatures will be fairly cool, in the 60s for all areas, except around 70 in the eastern Antelope Valley.
Some lingering light showers may affect a few areas, mostly the mountains, Sunday morning with drying and clearing likely by late morning. Highs will bump up a few degrees, mostly in the 60s still but with a few readings around 70 in the warmer valleys.
(Tue-Fri), 24/146 PM.
Another low impact weather day Tuesday except for some possible low clouds and fog near the coast. Otherwise, temperatures within a few degrees of normal under mostly sunny skies.
The prospects for rain later in the week appear to be decreasing, though the deterministic GFS is still holding on to some chances for light rain late Wednesday into Thursday morning. Most of the ensemble solutions are showing little to no rain with temperatures near normal. After that models are indicating weak high pressure aloft for Friday and Saturday leading to warming temperatures.

At 00Z at KLAX, there was no marine layer nor marine inversion.
Overall, moderate confidence in 00Z TAF Package. VFR conditions are generally expected through the evening. MVFR cigs are likely at coastal and valley sites. Timing could be off +/- 3 hours. Light rain is possible from 18Z onward for most sites.
KLAX, Moderate confidence in TAF. MVFR CIGs 020-025 expected around 25/11Z (+/- 2 hours). Likely to lift to 030-035 by late morning. No significant east wind component expected.
KBUR, Moderate confidence in TAF. VFR conditions expected through this evening. MVFR CIGs 025-030 likely to develop late tonight into early morning hours. Low confidence on timing (+/- 3 hours). 20% chance VFR conditions (VFR ceilings) prevail thru fcst pd. No wind issues expected.

For the Outer Waters, high confidence in current forecast. Across the waters south of Point Conception, especially near the Channel Islands, SCA winds will likely persist through Saturday night. Winds could drop below advisory levels at times Saturday morning. From Saturday afternoon through Monday, winds and seas are expected to remain below SCA levels. Chances for SCA level winds will increase from Tuesday onward.
For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. Localized SCA winds are possible this evening. Otherwise, high confidence in winds and seas remaining below SCA levels through Sunday. Chances for SCA winds will increase each day next week.
For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. SCA level W winds are expected later through late tonight focused across western portion of the Santa Barbara Channel and near the Channel Islands. Increased confidence in SCA winds across SB channel Saturday afternoon and evening. SCA may also be needed for the waters south of Point Mugu. On Sunday, onshore W winds will flirt with advisory levels especially nearshore during the afternoon into early evening hours. Slight chance for SCA level winds early next week focused across the usually favored waters with increasing chances Wednesday and Thursday.
A weak system will bring spotty showers across the coastal waters Saturday and Saturday night. This activity may linger into Sunday morning.
