SYNOPSIS
18/327 AM.
Strengthening onshore flow beneath southwest flow aloft will bring a cooling trend through Friday with more extensive night through morning low clouds and fog. A warming trend is expected over the weekend as weak ridging aloft builds in. A significant cooling trend with a deep marine layer depth is on tap for the middle-to-late portion of next week.
.SHORT TERM (TDY-SAT)...18/430 AM.
The latest water vapor shows a weak upper-level trough near 34N and 134W, or about 900 miles west of Los Angeles, while a deeper trough of low pressure sits upstream near 50N and 158W. Closer to the surface, onshore pressure gradients are strengthening across the area early this morning. The latest fog product imagery indicates a low cloud pattern becoming well-entrenched across the coastal waters and into all of the coastal areas early this morning, but the exact extent of the low cloud field remains in question due to the amount high level cloudiness moving over the region. A thick middle and high cloud shield, making for some difficulty seeing some of lower clouds on the infrared bands of satellite, will likely push a decent amount of cloudiness across the area today and this evening.
A partly to mostly cloudy day is shaping up across the region.
With the low clouds becoming more entrenched today and the weak trough sitting off the coast, there is some concern that a gloomy pattern could develop at the coast today. In fact, there is a high (50 percent) chance that clouds could hug the beaches today, struggling to clear from the land mass during the afternoon hours. The latest GFS LAMP guidance for KSBA and KOXR hints at the possibility of low clouds lingering into the afternoon hours today.
EPS ensemble cloud cover means moderately support this idea, but some of cloudiness could be diluted with middle and high cloud coverage as high-resolution multi-model ensemble members suggest.
With more onshore flow and cloudiness, a cooling trend will develop through Friday. The marine layer depth at KLAX, near 850 feet deep at KLAX a bit ago, will deepen through this morning to around 1200 feet deep. As trough moves closer to the region through tonight, the marine layer depth will likely deepen additional. The latest 3-km WRF solutions suggest marine layer depth approaching depths of 2500 feet deep by Friday morning, and possibly as high as 3500 feet deep by Friday night. If this materializes as modeled, this should push clouds well into the coastal slopes of the mountains, especially Friday night. Patchy morning drizzle cannot completely be ruled out on Friday morning and overnight Friday night into Saturday morning as 850 mb mixing ratios approach 9-10 g/kg and ample omega values exists through the mixed layer.
Cyclonic flow turns anticyclonic into Saturday as ridging aloft starts to nose into the California coast. A warming trend will establish on Saturday and likely persist through the weekend as the ridge axis slowly drifts over the region. GEFS and EPS ensemble members agree well that a warming trend will take shape starting Saturday.
.LONG TERM (SUN-WED)...18/432 AM.
The ridge axis will drift over the region sometime on Sunday and the warm up should peak for most areas on Sunday. There is a moderate chance that the warming trend could linger a little longer into the interior areas. EPS ensemble members suggest a mix of warmer and cooler solutions with means about the same at KPMD and KWJF on Monday.
A weak boundary dropping south of Sunday, and falling apart north of the area, could bring marginally gusty winds through the Interstate 5 Corridor and across southern Santa Barbara County on Sunday night and into Monday. EPS ensemble members indicate a tick up of winds at KSDB and KSBA, but the strength seems to be in question as there is a quite a bit of spread across the ensemble members solutions. Fortunately, there is still sometime to resolve the pattern setting up.
As we get into next week, a significant cool down is shaping up through the week. All EPS, GEFS, and CMC ensemble members indicate a cooling trend to be firmly in place for Tuesday and Wednesday as trough of low pressure digs into the region. Almost all of the ensemble member solutions have precipitation developing sometime between Tuesday and Thursday, but there is quite a bit of spread in regards to the timing. Amounts look light across the perturbations, on the order of a tenth of an inch or less, but there is a 10 percent chance that amounts could be more than that.
For the last several days, the forecast ensembles have highlighted this period as a possibility for another opportunity of rain, but it remains to be seen if it will amounts to drizzle or more light to moderate rainfall across the region.
AVIATION
18/1247Z.
At 12Z, the marine layer at KLAX was about 1300 ft deep. The top of the inversion was at 4000 ft with a temp of 16 deg C.
Widespread low clouds in coastal areas and in the Santa Ynez Valley this morning, with generally LIFR to VLIFR conds. Some VLIFR conds may push into the VTU County Valleys this morning, and into the San Gabriel Valley for a few hours. Low clouds will clear in most areas by late morning, but could linger into the afternoon near the coast, especially across southern SBA County and VTU County. Otherwise, expect lots of high clouds across the region. Low clouds will return to coastal areas this evening, then push into the valleys after midnight. Conds will be mostly IFR to LIFR, then improve late at night in coastal areas.
KLAX...Moderate to low confidence in the 12Z TAF. LIFR to VLIFR conds should improve to IFR by mid morning, but there is a 30% chance that will not occur until at least 17Z. There is a 30% chance that IFR to low MVFR cigs could linger thru 20Z. There is a 30% chance that cigs will arrive this evening as early as 01Z, and start off in the IFR category. Any east wind component should remain less than 6 knots.
KBUR...Moderate to high confidence in the 12Z TAF. There is a 20% chance of IFR cigs from 13Z-17Z this morning, and there is a 20% chance that cigs will not arrive tonight until at least 09Z.
MARINE
18/535 AM.
A very shallow marine layer will bring dense fog to a good portions of the coastal waters this morning.
High confidence in conds remaining below Small Craft Advisory (SCA)
levels thru Sat morning. SE winds around 10 knots should occur each morning from the SBA Channel southward to San Mateo Point. Locally stronger SE gusts are possible thru the Anacapa Passage and San Pedro Channel.
NW winds will likely reach SCA levels in the outer waters Sat afternoon thru Sun, and across the inner waters N of Pt. Sal and the SBA Channel during the afternoon/evening hours Sat and Sun.
There is a 30% chance of SCA conds in the outer waters Mon.
BEACHES
18/551 AM.
A long-period southerly swell cause elevated surf of 3 to 5 ft with local sets to 6 or even 7 ft on south-facing beaches of L.A.
County, Catalina Island, and possibly VTU County. There will be a high risk of rip currents on most beaches today.
