(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus66 klox 251953 afdlox area forecast discussion national weather service los angeles oxnard ca 1253 pm pdt Wed apr 25 2018 Synopsis 25 1148 am. A trough of low pressure will approach the west coast through Friday before settling over the region through early next week. This will result in a gradual cooling trend with increasing night to morning low clouds through Friday. It will be breezy at times in the evening to overnight hours and near normal temperatures will continue through the weekend. Short term (tdy-sat) 25 1214 pm. Southwest flow aloft and increasing onshore flow are the themes for the next few days as a large low pressure trough dominates across the eastern pacific ocean. This pattern will result in a deeper marine layer through Saturday with locally gusty southwest winds through the highway 14 corridor of the san gabriels and into the antelope valley. Pressure gradients increase 2-3 mb over today and reach a peak of 9.5 mb between lax-dag on Thursday afternoon. Wrf high-res model data also shows sustained winds over 25kts so would expect a wind advisory will be needed for the av for the afternoon and evening time frame. There will be weak north winds for the western canyons of the south santa barbara coast this evening. This may be just enough to kick stratus southward off the coast by Thursday morning, and models support this idea. Elsewhere, the low clouds and patchy fog may gray pattern will persist overnight and through the morning hours through Saturday. Temperatures will remain rather cool near the beaches and normal for inland valleys and mountains. Stronger onshore flow tomorrow will result in gusty west winds for the central coast in the afternoon. Then, we will see sundowner season get fully underway both Thursday and Friday evenings as north winds kick in for passes and canyons west of santa barbara. Advisory level winds look likely to occur with the sba-smx pressure gradient peaking between 4-5mb late Friday and again late Saturday. Long term (sun-wed) 25 1228 pm. Confidence in the longer term forecast is moderate. The eastern pacific low pressure trough moves inland across northern california and oregon over the weekend, then carves a trough throughout the great basin early next week. This brings a more northerly wind pattern into southwest california with periods of gusty north-northwest winds across the region. Depending on the location of the trough and or low pressure systems we could see some light showers in the mountains early in the week, but this scenario is an outlier and chances will remain under 15 percent. The ECMWF and to a lesser degree on the gfs, high pressure will build into the west coast by mid-week with temperatures rebounding on Wednesday with the start of a warming trend and weak offshore flow for the later part of the week.

At 1730z at klax, the marine layer was near 1500 feet deep. The top of the inversion was near 2600 feet with a temperature around 18 c. Moderate confidence in 18z tafs. MVFR CIGS toVFR transitions could be off by + - 1 hour. Good confidence in tafs 20z-04z. Then moderate confidence with persistent pattern once again tonight into Thursday morning. 40% chance that ifr MVFR CIGS could linger an additional compared to today. Klax...

High confidence in winds and seas remaining below small craft advisory levels across the waters through Thursday morning. Winds will likely increase across the outer waters Thursday afternoon through much of the following week. A gale watch has been issued for the two southern outer water zones starting Friday afternoon and continuing through early Monday afternoon. There is a 50% chance gale force winds will continue across the same area into early next week. NW winds will continue to be gusty across the northern outer waters zone but should remain below gale levels. There is a 70% chance that small craft advisory (sca) gusts will occur during the the same time period as the gale watch and into early next week. Expect building short period seas during this time as well that will translate into the inner waters. Inner waters for areas S of point conception... Waters should be mostly quiet through Friday morning, then strong SCA level gusts and a 40% chance that gale force winds could affect the western portion of the eastern sba channel Friday afternoon and evening. Gusty NW winds will become more widespread across the entire inner waters Saturday. 70% chance for SCA winds and 30% chance for gale force winds western portion of eastern sba channel in the afternoon.There will be a 40% chance for SCA across the inner waters from point sal north on Friday, and 70% chance for Saturday.

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. |
