Area forecast discussion, Feb 8, 9:10 PM PST, 5 hours 6 minutes before
Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 910 PM PST Mon Feb 8 2021 .SYNOPSIS...08/807 PM. Expect cooler temperatures this week with overnight and morning low clouds and fog in coastal and valley areas this evening. There is a chance of light precipitation at times across the region late Thursday through Saturday as an upper level low passes near the area. && .SHORT TERM (MON-THU)...08/841 PM. ***UPDATE*** No significant changes to the forecast. The deepening marine layer and steady onshore push is allowing low clouds (with minimal to no fog, unlike last night) to surge inland this evening. These clouds are already pushing into some valleys, and will continue to advance into the mountain foothills by morning...although it will be very hard to monitor with the ample high clouds obscuring the view from space. With the deepening marine layer, some drizzle is possible. Temperatures will drop tomorrow without surprise as a result. ***From Previous Discussion*** Overall, 12Z models in good agreement through the short term period. At upper levels, weak ridge will persist over the area through tonight with a weak trough moving across the area Tuesday night/Wednesday morning then ridging again Wednesday afternoon through Thursday. Near the surface, weak onshore flow will prevail with some weak northerly flow developing Tuesday night. Forecast-wise, main issue in the short term will be the marine layer stratus. With lowering H5 heights tonight and continued onshore gradients, expect the marine inversion to deepen. So, by Tuesday morning, will expect widespread stratus across the coasts and valleys and even pushing into the lower coastal slopes. Also with the deepening inversion, some patchy drizzle will be possible tonight/Tuesday morning south of Point Conception. Stratus should dissipate back to the coast Tuesday afternoon. With the weak northerly flow anticipated Tuesday night, stratus should be generally be limited to the coastal plains of Ventura/LA counties and interior sections of San Luis Obispo/Santa Barbara counties Tuesday night and Wednesday morning. For Wednesday night and Thursday, do not anticipated much, if any, stratus development. Other than the marine layer stratus, varying amounts of high clouds will drift overhead through Tuesday night, resulting in partly to mostly cloudy skies for the area. As for winds, the onshore gradients will generate some gusty southwesterly winds this afternoon and Tuesday afternoon across interior sections. However, speeds should remain below advisory levels. For Tuesday night through Thursday, there will be some weak northerly gradients developing. So, will anticipate some locally gusty northerly winds in the usual spots (Santa Ynez Range and I-5 Corridor). At this time, do not anticipate the northerly winds to reach advisory levels. As for temperatures, will expect a cool Tuesday for the area due to the onshore gradients and significant marine influence. For Wednesday and Thursday, a gradual warming trend is anticipated with less marine influence and rising H5 heights and thicknesses. .LONG TERM (FRI-MON)...08/204 PM. Overall, 12Z models have the same general idea, but definitely differ in the details. One upper level flow will move over the area Thursday and Friday, followed by another upper level low on Saturday night and Sunday. For the Thursday night/Friday system, the ECMWF moves the upper low south/southeast across the coastal waters while the GFS has the low tracking southeast over the land. So, the GFS indicates a bit better chance of precipitation for the area than the ECMWF. However, either solution does not generate much precipitation for the area. Will keep with the idea of low chance/slight chance POPs for this time frame. QPF amounts, if any, will be very light with most areas potentially receiving under 0.10 inches. Snow levels look to remain quite high, around 7000 feet or higher. So, no significant snowfall issues are anticipated. After a brief respite Friday night/Saturday morning, the next system is forecast to impact the area Saturday afternoon through Sunday. ECMWF is a bit faster with this system than the GFS, but both models indicate some precipitation chances between Saturday afternoon and Sunday afternoon. Looking at QPF progs, this system may produce a bit more widespread shower activity across the area. However, precipitation total will be light with initial estimates for under 0,25 inches for the area. Snow levels with this system will be lower, ranging from around 6500 feet on Saturday, but dropping to around 4500 feet Saturday night and Sunday. So, depending on the amount of shower activity, there could be some snow issues at the lower mountain elevations. Will need to watch this possibility over the next few days. && .AVIATION...09/0509Z. At 05Z over KLAX, the marine layer was 1900 feet deep. The top of the inversion was at 3600 feet and 13 degrees Celsius. High confidence of generally MVFR and locally IFR CIGS at all sites through Tuesday morning (except KPMD KWJF), with much higher cats compared to last night. Moderate confidence in timing, plus or minus 3 hours. There is a chance for LIFR FG at KSMX (40%) KSBP (20%) KSBP (20%), with little to no chance at other sites. Relatively poor clearing likely in the afternoon. With ample high clouds expected, satellite detection of low clouds will be nearly impossible which will make TAF updates challenging. KLAX...High confidence in MVFR CIGS most common, with a 20% chance for brief IFR 09-15Z. No chance of LIFR. Moderate confidence in timing plus or minus 3 hours. Southeast winds likely tonight, but most likely will stay below 8 kt. KBUR...High confidence in IFR CIGS common 09-15Z, and MVFR CIGS common otherwise through 20Z. Chance for LIFR is less than 10% Moderate confidence in timing plus or minus 3 hours. && .MARINE...08/902 PM. Fairly calm and under Small Craft Advisory (SCA) conditions will continue through Tuesday night, with a mixture of small long period and short period swells. NW winds will increase above SCA from the Central Coast to San Nicolas Island on Wednesday before relaxing on Thursday. There is a 20% chance of SCA winds impacting the West Central Santa Barbara Channel. Otherwise, short period seas will build everywhere Wednesday into Thursday from these winds, including the inner waters. A series of storm systems will bring widespread gusty winds (20-30 KT at times) and building seas (generally 6-12 feet) with short periods, peaking Friday through Sunday. && .LOX WATCHES/WARNINGS/ADVISORIES...
