(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 klox 191300 afdlox area forecast discussion national weather service los angeles oxnard ca 600 am pdt Mon aug 19 2019 Synopsis 18 721 pm. Temperatures will warm each day into midweek then cool again into next weekend. Many locations will have triple digit temperatures Wednesday and Thursday. Overnight and morning low clouds and fog will diminish in area a bit each day through Thursday then expand again beginning Friday. Short term (tdy-wed) 19 316 am. The marine layer is 1100 ft deep. There is 2 to 4 mb of onshore flow in all directions. The eddy was very late to spin up and low clouds have been late to form south of pt conception. The central coast and the northern half of the slo interior are already full of clouds. By dawn low clouds should cover the la and vta coasts as well as the san fernando and san gabriel vlys. There will be much less clouds in the vta vlys and the sba south coast. There are 2 mb offshore trends and these should bring a quicker and more complete clearing than ydy. Slightly higher hgts and weaker onshore flow will allow almost all areas to warm 2 to 4 degrees today. Offshore trend will continue tonight and there will be much less low clouds in the vlys and the sba south coast will also remain clear. Hgts rise to 591 dm on Tuesday as socal will be sandwiched between pac NW trof and a new mexico upper high. There will only be weak onshore flow and the higher hgts, reduced marine layer and delayed and weaker seabreeze will combine to warm temps 2 to 4 degrees across the board. MAX temps will be above normal across the interior, near normal in the vlys, slightly below normal over the interior coastal sections and well blo normal near the beaches. A 3 to 4 mb offshore push from the north is forecast to quickly develop Tuesday night. There will only be weak onshore flow to the east. Marine layer stratus will be confined to the la south coast and the central coast. The ksba-ksmx grad peaks at -3.9 mb and this should be enough to bring wind advisory gusts to the sba south coast ESP west of the airport. The mdls have changed their tune for Wednesday. The upper high is no longer forecast to move to the west and in fact trof will be over the north half of the state. Hgts will still be high, there will be offshore flow from the north and minimal marine layer so it will still be a warm day but perhaps not as warm as previously thought. Long term (thu-sun) 19 326 am. Not much change on Thursday. Skies will be mostly sunny with very little in the way of low clouds. A little less offshore flow so the coasts and vlys will cool a little. Still MAX temps will be above normal across the interior. The GFS and ec disagree on the Friday through Sunday forecast. Both mdls agree that there will be some sort of weak upper high overhead with hgts near 592 dm. The big difference is with the sfc gradients. The GFS has mdt to strong onshore flow while the ec has much weaker onshore flow and even some offshore flow. The gfs solution would be cooler with more marine layer while the ec would be warmer and clearer. The ec is the big departure from previous so trended the fcst to the gfs. The tropical system forecast to spin near baja Friday through Monday is still there but it is weaker and right now does not look like it will have much impact on la county and north. Still |
tropical systems can be tricky and cannot take our eyes off of it. Aviation 19 1259z. At 12z, the marine layer was around 2200 ft deep at klax. The top of the inversion was around 3500 ft with a temp of 22c. North of pt conception, low clouds were widespread in all coastal and valley areas with the exception of the far interior valleys of slo county and the cuyama valley. Conds were mostly ifr to lifr. Skies should clear by mid morning in the valleys and late morning or early afternoon across the coastal plain. Expect clouds to push into coastal areas and the santa ynez valleys this evening, and possibly into the salinas valley late tonight. Conds should be ifr to lifr once again. South of pt conception, clouds have pushed into coastal areas of l.A, county and the san gabriel and san fernando valleys, and will likely push into the vtu county coastal plain, eastern parts of the sba county south coast. Conds will be mostly ifr, except low MVFR across the l.A. County coast. Skies should clear by mid morning in the valleys and late morning on the coastal plain, except early afternoon at some beaches. Expect marine layer to be a bit more shallow tonight, with less cloud coverage in the valleys, and mostly ifr conds. Also, sundowner winds may keep south coastal sections of sba county and coastal sections of vtu county clear, at least through 12z. Klax... Moderate confidence in the 12z taf. There is a 20% chance that CIGS will linger until 20z. There is a 20% chance that cigs tonight will arrive as early as 06z. There is a 30% chance that cigs tonight will be in the MVFR category instead of ifr. Kbur... Moderate to high confidence in the 12z taf. There is a 20% chance of ifr CIGS after 09z tonight. Marine 19 333 am. For the outer waters, moderate to high confidence in current forecast. Small craft advisory (sca) level winds are expected to develop this afternoon and continue through at least late tue night, and possibly through late Thu night. There is a 50-60% chance of a period where winds drop below SCA levels late tue night and Wed morning. For the inner waters north of pt sal, only fair confidence in forecast beyond today. No SCA level conds are expected today. There is a 40-50% chance of SCA level winds during the afternoon and evening hours Tue through thu. For the inner waters south of point conception, SCA level conds are not expected through fri. The exception is across western portions of the SCA channel, where there is a 20-30% chance of sca level NW winds this evening, and SCA level NW winds are expected during the late afternoon through late night hours Tue and wed, Lox watches warnings advisories Ca... None. Pz... Small craft advisory in effect from 3 pm this afternoon to 3 am pdt Wednesday for zones 670-673-676. (see laxmwwlox).

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
