| Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 307pm PDT Tuesday May 30 2023 Synopsis 30/156 PM. A broad area of low pressure over the West Coast will keep a strong onshore flow in place along with a persistent and deep marine layer through Thursday. Night through morning low clouds and fog with limited afternoon clearing will continue through much of the week. There will be areas of drizzle or light rain possible again late tonight and Wednesday morning. There is a slight chance of thunderstorms in the mountains and in the far interior valleys of San Luis Obispo and Santa Barbara Counties through this evening. Temperatures will be below normal through Thursday then a warming trend is expected Friday and Saturday. Short Term - Today through Friday 30/306 PM. The latest satellite imagery shows an upper-level trough near Point Conception early this afternoon. The latest radar mosaic shows isolated shower activity along the Central Coast and into the interior portions of San Luis Obispo and Santa Barbara Counties. Shower activity is starting to develop and build over the Ventura County mountains currently. KSBP has picked up rain at the sensor within the last hour, but nothing has measured north of Point Conception. Only trace amounts have occurred as of the current time. A rather muddled cloud pattern exists across the region today as a deep marine layer depth remains in place. The latest AMDAR soundings indicate a marine layer depth near 5200 feet deep with a weak marine inversion. The trough has done its job cooling the top of the marine intrusion and mixing out the low clouds in some areas. The weak inversion in place across the area will likely make for some uncertainty overnight tonight and into Wednesday morning as far as cloud formation. There is some concern that light rain or showers could develop late tonight into Wednesday morning. NAM BUFR time height sections indicate measurable rain at many terminals across southern California. Probability of Precipitation has been nudged higher across the Southland as multi-model high resolution ensemble members suggest higher chances of rain across the South Bay and Los Angeles Harbor areas, and up into the coastal slopes of the Los Angeles and Ventura County mountains. EPS ensembles suggest a mix of members at KLGB with higher chances of a few hundredths of drizzle or light rain farther to the north. For now, mentions of drizzle have been added to the forecast, but future shifts will need to take a closer look at this. A bit better clearing is possible across the area on Wednesday in the wake of the trough, but ridging aloft nosing into central California on Wednesday afternoon should start to tighten the marine inversion again. As a result, a cooler and gloomy pattern will resume again through Thursday. Clouds will likely to struggle to clear on Thursday. Long Term - Saturday through Tuesday 30/304 PM. The latest ensemble members suggest a steady warming trend for late week and through next week. EPS ensemble solutions keep a persistent marine layer depth in place in the cloud coverage field, but the marine layer depth will thin, especially over the weekend. Temperatures will get close to normal in most areas by Saturday, and possibly warm above normal in the mountains and the Antelope Valley. Southwest flow aloft should develop early next week as an upper- level low pressure will approach the West Coast. EPS ensemble members suggest cooler weather developing with a deeper marine layer. Night through morning low clouds will likely struggle to clear away from the land mass each day for the early portion of next week. Marine 30/142 PM. For the Outer Waters, moderate to high confidence in current forecast. Today through Wednesday morning, high confidence in winds and seas remaining below Small Craft Advisory (SCA) levels. From Wednesday afternoon through Friday, there is a 60-80% chance of SCA (Small Craft Advisory) level winds and seas. For Saturday and Sunday, there is a 30-50% chance of SCA (Small Craft Advisory) level winds. For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. Today through tonight, high confidence in winds and seas remaining below SCA (Small Craft Advisory) levels. For Wednesday through Friday, there is a 50-70% chance of SCA (Small Craft Advisory) level winds in the afternoon and evening hours. For Saturday and Sunday, high confidence in winds and seas remaining below SCA (Small Craft Advisory) levels. For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. Today through Sunday, high confidence in winds and seas remaining below SCA (Small Craft Advisory) levels for a majority of the southern Inner Waters. The only exception will be the western half of the Santa Barbara Channel, where there is a 40-50% chance of SCA (Small Craft Advisory) level winds during the afternoon and evening hours, both Wednesday and Thursday. NOAA Los Angeles/Oxnard CA Office: Watches - Warnings - Advisories CA...NONE. PZ...Small Craft Advisory in effect from 3pm Wednesday to 3 AM PDT Thursday for zones 670-673-676. |
