Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 645 PM PDT Tue May 14 2024

SYNOPSIS
14/116 PM.

Generally stagnant pattern through early next week with little day to day changes. Persistent low clouds and below normal temperatures will dominate the coastal side of the mountains, with above normal temperatures and gusty onshore winds on the interior side. The only wrinkle is a low chance of showers in the mountains each afternoon through Wednesday.

.SHORT TERM (TDY-FRI)...14/116 PM.

Very little change on tap through at least Friday. A weak upper level low will slowly depart the area through late Wednesday, with weak ridging by Friday. This will bring some steady warming to the interior mountains and valleys, with temperatures 5 to 10 degrees above normal by Friday. On the coastal side of the mountains however, this upper level change should have little affect. While increasing high pressure aloft tends to lower and shrink the marine layer, onshore pressure gradients will be strengthening some at the same time which has the opposite affect.
While the marine layer depth and coverage will unlikely be exactly the same each day, these two factors and the latest stagnant low level humidity projections all suggest that any changes will be small. As a result, temperatures will remain 5 to 10 degrees below normal on the coastal side of the ranges, with any day-to-day changes owing to the random fluctuations of earlier or later low cloud clearing times.

Onshore wind gusts will increase and expand over the interior areas as they have been each day, with gusts of 20 to 35 mph common (strongest in the Antelope Valley with local gusts to 40 mph possible). Winds could be 5 mph or so stronger Thursday and Friday with the stronger onshore pressure gradients, which may push us into the low-end Wind Advisory category for the Antelope Valley. Elsewhere, winds will be fairly seasonal.

The upper level low will also weakly destabilize the atmosphere through Wednesday. While the moisture aloft is the main limiting factor, there is a little (850mb dewpoints around 8 degrees Celsius). In addition, the convective clouds and moisture currently over southern Nevada and northwest Arizona will move over our area later tonight into Wednesday morning. These clouds could inhibit the convective potential some tomorrow, but if they thin out in the afternoon like the computer models suggest, then this could instead provide an extra moisture boost to the convection potential. As a result, while still unlikely, there is a 20 percent of showers for the typical shower magnets in the San Gabriel Mountains and north Ventura Mountains. While not explicitly in the forecast, there is also a 10 percent chance that any shower grows into a thunderstorm. Lastly, while a very small but non-zero chance, cannot completely discount a few drops or an isolated shower over valley areas Wednesday morning and afternoon.
This is due to the clouds previously mentioned, as well easterly steering flow capable of pushing any showers off the mountains.

.LONG TERM (SAT-TUE)...14/117 PM.

A series of small but potent low pressure systems will push through the Pacific Northwest over the weekend. This will break down the ridging aloft from Friday over the southwest. Another weak upper level low will form 800 miles west of Los Angeles by Thursday and remain parked through Friday. The systems to the north will also draw this low closer to the coast, with a fairly large spread in the ensemble solutions in terms of how fast and how far west it progresses. By Monday or Tuesday, most solutions have the low swinging through the area, with ridging aloft reforming towards the middle of next week. These trends should deepen the marine layer over the weekend, peaking Sunday and Monday when areas of drizzle looks favorable. Cooler conditions are expected as a result. Coastal areas, being cool already, will not notice the change too much. Interior areas however will go from 5-10 degrees above normal on Friday, to below normal by Monday.

AVIATION
14/1637Z.

At 1630Z at KLAX, the marine layer was 2700 feet deep. The top of the inversion was around 3600 feet with a temperature of 17 degrees Celsius.

Overall for the 18Z TAF package, high confidence in desert TAFs and moderate confidence in coastal/valley TAFs. Lower confidence for coastal/valley sites due to uncertainties with timing of dissipation and formation of stratus.

KLAX...Moderate confidence in 18Z TAF. There is a 20-30% chance that MVFR CIGs will not dissipate this afternoon. Timing of flight category changes could be +/- 2 hours of current forecast. No significant easterly wind component is expected.

KBUR...Moderate confidence in 18Z TAF. Dissipation of MVFR CIGs could be as late as 21Z. Return of MVFR CIGs could be +/- 2 hours of current 06Z forecast. Also, there is a 30% chance of IFR CIGs 08Z-14Z.

MARINE
14/1209 PM.

For the Outer Waters, moderate to high confidence in current forecast. Today through Thursday, high confidence in winds and seas remaining below Small Craft Advisory (SCA) levels. For Thursday night, there is a 30-40% chance of SCA level winds around Point Conception. For Friday through Sunday, high confidence in winds and seas remaining below SCA levels.

For the Inner Waters north of Point Sal, high confidence in current forecast. Today through Sunday, winds and seas will remain below SCA levels.

For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. For most of the southern Inner Waters, winds and waves will remain below SCA levels through Sunday. The only exception is the western half of the Santa Barbara Channel where there is a 30-40% chance of SCA level winds late Thursday afternoon and evening.
