Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 1004 AM PST Tue Nov 28 2023
SYNOPSIS
28/440 AM.
Today will be the last dry day with temperatures near to slightly above normal, then a cool and unsettled weather pattern will develop for the latter half of the week as a series of Pacific storm systems move over the region. Occasional light showers with snow above 5500 feet is expected Wednesday through Saturday. A warming and drying trend is expected Sunday into early next week.
.SHORT TERM (TDY-THU)...28/905 AM.
***UPDATE***
The Hard Freeze Warning for the Antelope Valley has expired as temperatures continue to rise. The forecast has been updated to account for the expiration of this headline. Otherwise, high temperatures today will be near to slightly above normal readings in most areas. No other changes have been made to the ongoing forecast.
***From Previous Discussion***
High pressure aloft over the region is starting to break down early this morning. An upper-level trough about 700 miles northwest of Point Conception, or near 38N and 132W, will approach the California coast through tonight, while the center of circulation opens up. A cold front can be seen stretching off to the south and southwest of the circulation off the California coast.
A dry day is on tap for today with temperatures from near to slightly above normal for this time of year. It will be a chilly start to the day across the interior valleys and wind-sheltered areas. Freeze warnings remain in effect across the Antelope Valley this morning. Middle to high clouds will start to exit the region around daybreak giving away mostly clear to partly cloudy skies.
The frontal boundary offshore will move over the region Wednesday and Wednesday evening. The highest chances for rain are for areas along the Central Coast. High-resolution multi-model ensembles are starting to hint at categorical rain along the Central Coast on Wednesday morning. EPS and GEFS solutions indicate precipitable water values climbing to between 0.80 and 0.90 inch across the region Wednesday and Wednesday night, or about 125-150 percent of normal for this time of year. 850 mb mixing ratios approach 4-6 g/kg in the latest deterministic solutions, more than ample for supporting rain during the late fall season. PoPs break away from NBM values across the region Wednesday through Thursday night to highlight higher chances for the northern areas, including the north slopes of the mountains, and lower chance for areas south of Point Conception due to downsloping from Transverse Range. Rain chances will increase through the day Wednesday, then wanes away as the pattern turns showery into late Wednesday night and Thursday. Another increase in PoPs will take place for late Thursday and Thursday night as the next weak weather system pushes into the region. Rainfall amounts with the first system look to be a quarter inch or less, except local amounts between 0.25 and 0.50 inch in northwest San Luis Obispo County. Showers, thereafter for Thursday and Thursday night will likely amount to 0.10 inch or less.
There is a non-zero (less than 10 percent) chance of thunderstorms on Wednesday across San Luis Obispo County as the 500 mb cold pocket around -24 degrees Celsius shoots across the area. It is marginal for thunderstorms, but given that a lightning strike has already been observed offshore, it bears watching at this point. The next shift will be briefed about the possibility of upping thunderstorms chances.
Snow levels will remain above 5500 feet for the first storm system, keeping any snow accumulations on the highest roadways, including Lockwood Valley Road in Ventura County and the Angeles Crest Highway in Los Angeles County, but snow levels will start lowering into Thursday and Thursday night down to around 4500 feet by Friday morning possibly affecting some of the lower elevation roadways.
.LONG TERM (FRI-MON)...28/440 AM.
Another wave will drop down in the northwest flow pattern and bring another weak weather system south. This system has the potential to bring showers to the northern areas and the northern slopes of the mountains. About half of the EPS solutions produce accumulating snow for KSDB, but only one solution of the NAEFS solutions produces snow at this times. As KSDB is a bit higher than the Tejon Pass, there is a 10-15 percent chance of accumulating snow on the Grapevine portion of the Interstate 5 Friday, but that could change if a much colder air mass pushes south. Almost all of the EPS ensemble members and a majority of the CMC ensemble members do indicate precipitation (rain and/or snow) for the Grapevine on Friday, with GEFS ensemble members trending drier.
Friday's weak system will likely end up being dry for Ventura County and much of the coastal and valley areas in Los Angeles County. Gusty northerly winds are starting to look more likely between Thursday night and into Saturday. EPS members continue to increase wind gust means at KSDB, K3A6, KVNY, and KSBA with a handful of EPS members with 55+ mph gusts at KSDB on Friday. If traveling through the Interstate 5 Corridor this weekend, please monitor the latest forecast due to the potential for precipitation and gusty winds.
Ridging aloft will likely build in for early next week and bring a warming trend into Tuesday. EPS members suggest the warming trend only lingering into Tuesday, but GEFS members extend it into much of next week. NAEFS surface pressure gradients suggest offshore flow in place for KLAX-KDAG and KSMX-KBFL for much of next week. CMC ensemble members advertise the strongest offshore pressure gradients and potentially producing a moderate to strong offshore pattern for next week. The forecast keeps with NBM values which has a warming trend advertised through Tuesday.
AVIATION
28/1803Z.
At 1735Z at KLAX, there was no inversion or marine layer.
Expect some high clouds with MVFR conds across most of the region thru late tonight. Some mid level clouds associated with a frontal system may push into SLO/SBA Counties around midnight, with some MVFR cigs there late tonight, and a 20% chance of VCSH after 13Z.
KLAX...High confidence in the 18Z TAF with VFR conds thru late tonight. Some MVFR cigs are expected after 15-16z. There is a 20% chance of an east wind component of 7-8 kt thru 17Z this morning.
KBUR...High confidence in the 18Z TAF with VFR conds thru the pd.
MARINE
28/901 AM.
In the Outer Waters, winds and seas are expected to remain below Small Craft Advisory (SCA) levels thru Thu morning. From Thu afternoon thru Sat, SCA level NW winds are expected. There is a 20-30% chance of GALE FORCE winds Thu night into Fri, mainly across the western portion of the outer waters.
For the Inner Waters N of Pt. Sal, winds and seas are expected to remain below SCA levels thru Thu morning. SCA level NW winds are likely late Thu afternoon into Thu night, and again Fri afternoon and evening. There is a 30% chance of SCA level NW winds Sat.
For the Inner Waters S of Pt. Conception, winds and seas are expected to remain below SCA levels thru early Thu afternoon. SCA level W-NW winds are likely across the SBA Channel and the inner waters from Malibu to Pt. Mugu to Anacapa Island late Thu thru Fri evening, with a bit of a lull in the winds possible Fri morning, There is a 20-30% chance of SCA conds Sat.
