(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 klox 171720 afdlox area forecast discussion national weather service los angeles oxnard ca 1020 am pdt Sat aug 17 2019 Synopsis 17 654 am. Temperatures will be cooler this weekend then warmer next week with the highest readings midweek. Overnight and morning low clouds and fog will continue in coastal and adjacent valley areas through Monday then will be primarily along the coast through Wednesday. Short term (tdy-mon) 17 903 am. The marine inversion this morning was near 2600 ft deep at lax. Low clouds were quite widespread this morning, extending from the coast well into the vlys and even into some lower coastal slopes. The low clouds are forecast to clear back to the coast by midday with low clouds probably lingering at some of the beaches thru the afternoon thanks to good onshore gradients, which are expected to be around +9.2 mb at 00z according to the latest nam. Otherwise, mostly sunny skies will prevail across the region thru the afternoon. The good onshore gradients will promote gusty S to W winds across much of the foothills, mtns and deserts this afternoon. Temps will be much cooler across the forecast area as well, with highs expected to reach only into the 80s in the warmer vlys and lower mtns, altho the antelope vly should still warm into the 90s this afternoon. Temps overall across the region today will be 6-12 deg below normal for this time of year. An upper level trof will persist along and off the ca coast today thru sun, with h5 heights in the 586-588 dm range. A large upper level high over the southern plains will start to slowly expand w and into SRN ca Sun night and mon, with h5 heights expected to increase to 590-591 dm for Mon afternoon. A dry SW flow aloft will prevail for the most part thru the period. The marine inversion is expected to be slightly lower tonight into sun morning, then shrink to about 1500-1800 ft or so Sun night into mon morning. Even so, plenty of night and morning low clouds and fog will affect the coastal areas into portions of the adjacent vlys during the period. Low clouds and fog will likely affect the salinas river vly for the late night and morning hours as well thru mon morning. Otherwise, mostly clear skies will continue across swrn ca thru mon. The onshore flow will slowly decrease thru the period, with the lax- dag forecast gradient (nam) expected to be about +8.3 mb sun afternoon, and +7.3 mb Mon afternoon. Some gusty s-w afternoon and evening winds will continue for the foothills, mtns and deserts each day, with some gusty NW winds forecast for the central coast. Temps are expected to remain about 6-12 deg below normal for many areas on sun, then warm slightly to about 2-7 deg below normal for mon. The warmest vlys and lower mtns should reach the 80s on sun, and mid 80s to low 90s mon. The antelope vly should be in the 90s each day. Long term (tue-fri) 17 313 am. By Tuesday the upper-level high will push further west and hgts will rise to 594 dm over SRN ca. The onshore flow to the east will be weak and offshore flow will develop from the north. This will greatly reduce the marine layer stratus pattern and will bring another 3 to 6 degrees of warming to all areas. Similar to this week's warm up, Wednesday and Thursday will be the warmest days and if the forecast remains valid there will be a need for heat products. Hgts will remain near 594 dm, or about 5 dm higher than normal. Weak onshore flow to the east and 2 to 3 mb offshore flow from the north is expected. There will be minimal morning stratus. Temperatures will jump another 4 to 8 degrees and will be above normal almost everywhere. The ridge will break down |
a little on Thursday which will drop MAX temps by 2 to 4 degrees. The ridge breaks down further next Friday and the onshore flow begins to reassert itself. The marine layer and the attendant marine layer stratus will begin to redevelop. MAX temps will fall another 2 to 5 degrees. Still tracking a tropical system forecast to develop around southern baja california Friday and move to the north. The moisture and swell from this system could affect SRN ca's weather during the week of the 26th. Aviation 17 1720z. At 1615z, the marine inversion at klax was based at 2700 feet. The top of the inversion was 4500 feet with a temperature of 23 degrees celsius. Overall, moderate confidence in 18z coastal valley tafs and high confidence in desert tafs.

For tonight, high confidence in return of stratus fog to all coastal and valley sites, but only moderate confidence in timing. Klax... Overall, moderate confidence in 18z taf.

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. |
