What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Los Angeles, CA wrote its last area forecast discussion before this small craft advisory went out at Sep 25, 11:57 PM PDT, 2 hours 46 minutes earlier.
Area forecast discussion, Sep 25, 11:57 PM PDT, 2 hours 46 minutes before
Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 1157 PM PDT Sat Sep 25 2021 .SYNOPSIS...25/1254 PM. A cooler weather pattern will continue into early next week as a couple of upper lows move through the region. Overnight low clouds and fog will become more widespread across the coast and valleys. A warming trend is expected the latter half of next week as high pressure returns and onshore flow weakens. && .SHORT TERM (SAT-TUE)...25/901 PM. ***UPDATE*** The upper level low pressure system just to our south supported convection today, but lacked sufficient vorticity required for heavier showers and thunderstorms. However, showers still formed over the Antelope Valley and the L.A. Basin. Otherwise, it was a cooler day with light winds through most of the region. Smoke from the southern Sierra fires is blanketing San Luis Obispo and the northwest half of Santa Barbara County this evening, as a result of easterly flow. Stratus has already moved into the Central Coast, Ventura County Coast, and portions of the L.A. Coast. The LAX-DAG pressure gradient of 4.3 mb supports the strong westerly push, and will trend stronger into Sunday and Monday. Expecting stratus to push into the Santa Barbara south coast as the eddy spins up, through the plains and may even reach lower portions of the San Gabriel and San Fernando valleys. The marine layer is a similar depth as last night (around 700 feet), but is forecast to deepen later tonight. Winds will be light for most of the area, save some sub- advisory level west winds in the Antelope Valley. Overnight, upper level flow will become more northerly as the low shifts to the east northeast over Arizona, pushing the smoke back into Ventura and L.A. County Sunday morning. This may lead to reduced visibilities in the Antelope Valley and foothills. Sunday, temperatures trend even cooler with increased onshore flow. Clouds should struggle to clear over most of the coast waters and linger at the beaches, especially west facing shorelines. The forecast looks on track, with minimal changes needed. ***From Previous Discussion*** Otherwise, forecast on track for a storm-free day Sunday with temperatures very similar to today. The marine layer should be deep enough to reach the coastal valleys but depending on convection today it may get too late a start to get in there. The rest of the forecast is more or less unchanged. A little ridge pops up Monday in between upper lows but with onshore flow continuing to increase temperatures will either be about the same or even slightly cooler than the weekend. Also, with no convection the marine layer stratus should be able to fully rebound and move into the valleys overnight. On Tuesday the next trough arrives with a decaying cold front moving through during the day. Not expecting any rain from it, however, a deepening marine layer and stronger onshore flow to the east will cool temps even further with most areas 4-8 degrees below normal. And some morning drizzle is possible as well. It will likely be a slow clearing day for areas south of Pt Conception, but north of there gusty northwest flow will start up by late morning and help scour out the marine layer. As that northwest flow reaches the Santa Ynez Range later Tuesday expect some gusty Sundowner winds through the passes and canyons into southern Santa Barbara County, possibly reaching advisory levels. .LONG TERM (WED-SAT)...25/106 PM. Northwest flow and cold advection from the trough moving through should clear out the marine layer by Wednesday afternoon and leave it clear the rest of the week. Models have been consistent showing rapidly weakening onshore flow, and in some cases even turning weakly offshore by Thursday and Friday. This will help warm temps up rapidly with highs back into the 80s and 90s, even for some of the coast. Very little change going into next weekend. && .AVIATION...26/0656Z. At 06Z, the marine layer depth was around 1100 feet deep at KLAX. The top of the inversion was near 2900 feet with a temperature near 21 degrees Celsius. Moderate confidence in the current forecast coastal and valley terminals. High confidence in the current forecast for desert terminals. Higher confidence exists in timing, less confidence in flight categories. LIFR to IFR conditions should remain in place through at least 08Z, or as late as 16Z, then conditions should improve to IFR to MVFR conditions. There is a moderate (30-50 percent) chance of MVFR conditions lingering at most coastal terminals later than forecast or through the day on Sunday. An early return should be expected for coastal terminals on Sunday evening. KLAX...IFR conditions should improve to the MVFR category between 08Z and 12Z. There is a 40 percent chance of MVFR conditions lingering until as least 20Z, with a lesser chance of MVFR conditions lingering through the day. Should VFR conditions develop, MVFR conditions could return as soon as 01Z or as late as 03Z. KBUR...IFR conditions will spread into KBUR as soon as 07Z or as late as 10Z. Conditions should improve to the MVFR category between 10Z and 14Z. There is a 40 percent chance of MVFR conditions lingering until 18Z. && .MARINE...25/948 PM. High confidence that winds will remain below Small Craft Advisory (SCA) level through Sunday. Winds will strengthen across outer waters Monday, with a 60% chance of SCA level winds developing over the waters north of Pt Sal Monday morning, extending to the outer waters north of San Nicolas Island by Monday evening. SCA level winds are likely to last from Monday through Thursday. There is a 30-40% chance of GALE FORCE wind gusts at times across the outer waters Tuesday afternoon into Wednesday morning. For the inner waters north of Pt. Sal, winds will remain below SCA levels through Monday afternoon. SCA level winds are likely Monday evening through Wednesday afternoon. There is also a 20% chance of SCA conds Wednesday night and Thursday. For the SBA Channel and southern inner waters, winds will remain below SCA levels through Thursday. There is a 40% chance of SCA level wind gusts Tuesday evening for the western SBA Channel. && .LOX WATCHES/WARNINGS/ADVISORIES... CA...NONE. PZ...NONE. && .HAZARD POTENTIAL OUTLOOK (TUE-SAT). Gusty northwest winds are possible across San Luis Obispo and Santa Barbara Counties and adjacent coastal waters late Tuesday through Wednesday. && PUBLIC...Phillips/MW AVIATION...Hall MARINE...Lund/Stewart SYNOPSIS...MW weather.gov/losangeles
