Updated national weather service los angeles oxnard ca 457 pm pdt Mon apr 23 2018 Synopsis 23 1159 am. A weak high pressure ridge, moderate onshore flow, and overnight through morning coastal low clouds and fog are expected for the week. As a weak low pressure system approaches the area later in the week, temperatures will cool a few degrees through Saturday. Short term (tdy-thu) 23 112 pm. Quiet weather pattern next several days with a solid, though relatively shallow marine layer and moderate onshore flow. Don't really see any mechanisms to alter the low cloud coverage or depth significantly at least through mid week or so. Temps also will be more or less the same as today with just minor day to day fluctuations based on stratus clearing time and onshore strength. Clouds will likely linger at some beaches through the afternoon, much like they did today north and west of malibu. By Thu the upper low that will have been only slowly moving towards the coast earlier in the week will finally start to lift out to the northeast. As it does it will shove the weak upper ridge currently over us to the east and result in more cyclonic flow aloft and likely a deepening of the marine layer. So the trends for Thu should be cooler with slower clearing and stronger onshore flow. Long term (fri-mon) 23 120 pm. There could be a little increase in northerly flow early Friday as the first little trough passes through but overall probably little change going into Friday with the marine layer coverage and temps. There are differences in the handling of the upper pattern over the weekend and into early next week but either way we should be looking at a deeper marine layer and temps dropping below normal as heights drop quite a bit, though very little chance of any precip aside from possibly some morning drizzle, especially Sunday Monday. Both those days could have pretty slow clearing, even inland. Aviation 23 2354z. |
At 23z, the marine layer depth was near 800 feet deep at klax. The top of the inversion was near 2000 feet with a temperature around 21 degrees celsius. Moderate confidence in the current forecast. At coastal terminals, conditions will deteriorate to the lifr to ifr category through 06z. Vlifr conditions are likely at central coast terminals through 14z or 15z. Otherwise, conditions will gradually lift one category between 06z and 14z. MVFR conditions could linger at coastal terminals into Tuesday afternoon, especially ksba and koxr. Klax...VFR conditions will deteriorate to lifr between 02z and 04z. There is a 30 percent chance of vlifr conditions between 03z and 08z. MVFR conditions should develop between 11z and 15z and there is a 30 percent chance that MVFR conditions could linger until as late as 20z and a 20 percent chance that MVFR conditions could linger throughout Tuesday afternoon. Kbur...VFR conditions are expected throughout the period, except for a 10 percent chance of MVFR visibility between 13z and 15z. Marine 23 122 pm. Widespread fog with visibilities of one mile or less will likely persist through Tuesday morning, and possibly reform at night and continue through Thursday. The afternoon and evening hours should be slightly improved, but areas of reduced visibilities will linger. High confidence in winds and seas remaining below small craft advisory (sca) strength everywhere through Wednesday. Winds will be increasing Thursday through Saturday with widespread sca conditions and building short period seas likely. Lox watches warnings advisories Ca... None. Pz... None.
