Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 805 PM PDT Mon Apr 29 2024
SYNOPSIS
29/225 PM.
Mostly clear skies and warmer temperatures will prevail across the region through this week, although some night through morning coastal low clouds and fog can be expected at times through Wednesday. Gusty northwest to north winds will prevail over the mountains and deserts through Wednesday, then turn NE and gusty over portions of Ventura and Los Angeles Counties Wednesday night into Thursday. There is a slight chance of rain with cooler temperatures later in the upcoming weekend.
.SHORT TERM (MON-THU)...29/804 PM.
***UPDATE***
Skies were clear this evening with gusty northerly winds across many interior mountains and deserts to southwest Santa Barbara County. A small fire was ongoing across the northern Antelope Valley.
Low confidence forecast for low cloud and fog formation this evening focused across the LA Basin near sunrise tomorrow as the closest low clouds are focused near San Diego. However, a -1.5 Santa Barbara to San Diego gradient should support at least a moderate eddy, which may support the low clouds developing as is currently forecasted (50-60 percent chance of occuring).
Forecast on track with no adjustments scheduled.
***From Previous Discussion***
There were some low clouds right along the L.A. County beaches early this afternoon which may persist thu late afternoon.
Otherwise sunny skies covered the forecast area with little change expected thru sunset.
Northerly pressure gradients helped to keep gusty NW to N winds over portions of the SW SBA County mtns and coast, VTU County mtns, L.A. County mtns along the I-5 Corridor, and the western Antelope Vly foothills into the Antelope Vly. Advisory level wind gusts to 40 to 50 mph at times can be expected in these areas this afternoon and Wind Advisories will continue. Breezy to gusty W-NW winds will also affect much of the coast and adjacent vlys thru this afternoon, strongest on the Central Coast where winds could approach Advisory levels at times.
A flat upper level pattern with H5 heights around 576 dam will persist over the area, helping to keep temps near normal to a few degrees above normal. Highs this afternoon for the inland coast, vlys and lower mtns should reach the 70s to low 80s, with the warmest temps in the western San Fernando Vly.
Flat upper level ridging with H5 heights around 576 dam will persist over the area tonight thru Tue, then very weak upper level troffiness should move in by Wed with H5 heights falling slightly to around 572-573 dam. The weak upper level troffiness should linger Wed night and Thu as well.
Low clouds should affect the L.A. County coast tonight into Tue morning, and for the L.A./VTU County coast Tue night into Wed morning. There should also be more low clouds late tonight into Tue morning for the Salinas River Vly. Otherwise and elsewhere across SW CA, mostly clear skies will prevail thru Thu.
Strong and gusty NW to N winds are expected to continue tonight thru early Wed afternoon for the VTU County mtns, L.A. County mtns around the I-5 corridor and along the Hwy 14 corridor, and the western Antelope Vly foothills into the Antelope Vly. Gusty northerly winds are also expected for the SBA County mtns including Santa Ynez Range, and the SBA County S coast especially below the favored passes and canyons. Gusts to 40 to 55 mph will be possible at times. Wind Advisories are be in effect or will be issued for these areas thru Wed afternoon. Please see the latest Non-Precipitation Weather Message (LAXNPWLOX) for further details on the Wind Advisories.
For the coast and vlys, breezy to gusty sub-Advisory level W to NW winds can be expected each afternoon, strongest along the Central Coast.
As pressure gradients turn sharply offshore to the E Wed night, winds are expected to turn more to the NE Wed night into Thu, with gusty winds possibly to Advisory levels expected by Thu morning for the favored portions of VTU/L.A. Counties.
Temps are forecast to be near normal to a several degrees above normal Tue thru Thu, altho Thu should be the warmest day overall thanks to the offshore flow. Highs for the inland coast, vlys and lower mtns should reach generally into the 70s to lower 80s each day.
.LONG TERM (FRI-MON)...29/222 PM.
The GFS and EC deterministic and mean ensembles are in generally good agreement Fri, but then diverge Sat and Sun as the GFS continued to dig a significant (for early May) upper level trof into CA late Sat thru Sun along with a surface cold front, bringing the potential for measurable rain across the region. The EC is weaker with the upper trof and just brushes a dissipating cold front across the region Sun with a small chance of measurable rain. As far as the GFS mean ensembles, there were 18 members out of 30 showing precipitation across the fcst area this weekend, while yesterday's run had only 4 members with any rain. The NBM, meanwhile, is keeping POPs very low and less than 10 percent.
Given that the EC now has some rainfall possibilities, have opted to go against the NBM and introduce mostly slight POPs to the fcst Sat night into Sun. Due to lingering uncertainties it is too early to tell how much rain we may receive from this system, but up to 0.10 inch may fall for many areas. However, the potential exists for as much as one quarter to one half inch of rainfall from Sat night thru Sun. We will know more as additional model runs come in over the next few days.
Dry weather is expected Fri into Sat, with a slight chance of rain for northern SLO County late in the day. The front is expected to move across the forecast area Sat night and Sun with a band of mainly light rainfall, then dry weather should return on Mon. Temps will be near normal to slightly above normal Fri, then should cool to a few degrees below normal by Sun before rebounding some on Mon.
AVIATION
29/1739Z.
At 1719Z at KLAX, the marine layer was 500 ft deep with an inversion top at 2300 ft with a maximum temperature of 17 C.
High confidence in TAFs, except for KLAX and KLGB (30% chc of no cigs), KSMO (40% chance of IFR cigs from 12Z-16Z Tue), and KOXR (15% chance of IFR cigs after 14Z Tue).
KLAX...Moderate confidence in TAF. There is a 30% chance of no cigs developing tonight. No significant easterly wind component is expected.
KBUR...Moderate to high confidence in TAF, some uncertainty in wind direction after 04Z Tue.
MARINE
29/154 PM.
For the outer waters, the extended period of gale force winds is expected to continue thru at least Tue night. Swell will continue to be steep and choppy, a significant hazard to small vessels in particular. SCA conds are expected for the outer waters, Wed thru Fri, with a 30% chance of gales persisting into Wed night.
In the inner waters N of Pt. Sal, SCA level winds are likely thru Tue night, with a 25% chance of gale force winds this afternoon/evening. Then, there is a 50% chance of SCA conds late Wed thru Fri. Seas are expected to be at/near SCA level through Wed.
In the SBA Channel, SCA level W-NW winds are expected, particular across western portions, during the afternoon thru late night hours thru Wed. Winds will likely remain below SCA levels for eastern portions of the channel, most of the time through the period.
In the southern inner waters, there is a 20% chance of SCA level W to NW winds across northwestern portions, mainly from Anacapa Island to Malibu during the late afternoon thru late evening hours today thru Tue.
BEACHES
29/947 AM.
Persistent strong winds and outer water swell heights of 10-15 feet with a 10 second period will lead to high surf (8-12 feet)
along the Central Coast this afternoon through Tuesday night.
Surf will be highest across northwest-facing beaches. There is a 40% chance of high surf advisory criteria lingering through Wednesday evening. NO coastal flooding is expected.
