Area Forecast Discussion...UPDATED National Weather Service Los Angeles/Oxnard CA 929 PM PDT Sat May 4 2024

SYNOPSIS
04/928 PM.

A cold storm system is moving over the region, bringing periods of light rain to the area through tonight. Temperatures will be much cooler than normal through Sunday, but warmer than the previous day, and there will be gusty winds at times. Dry and warmer weather is expected next week.

.SHORT TERM (SAT-TUE)...04/926 PM.

***UPDATE***

High temperatures today were colder than normal by 8 to 12 degrees, with most highs in the 60s. Daytime heating was tempered by a deep marine layer in the morning, followed by increasing high clouds and a cooling airmass as the tail end of a dying front affected the region.

The front produced light rain across San Luis Obispo and Santa Barbara counties starting late this afternoon. Totals are mostly under 0.10 inches, with 0.25 - 0.5 inches across mountain and foothills, and the NW portion of SLO county. The only measured outlier is Rocky Butte (NW SLO county), that saw 0.91 inches.
Light rain reached Ventura County this evening, and is just starting to affect portions of LA county. Rainfall totals for these southern counties are still expected to be light and low impact, with under 0.10 inches across coasts, valleys, and deserts. Rain is still expected to subside for all but mountain areas by tomorrow morning.

Tomorrow skies are expected to be partly cloudy to clear with little temperatures inversion following the frontal system. This will allow temperatures to warm somewhat compared to the previous day for much of SLO and SBA Counties (4 to 8 degrees), and coasts and valleys of Ventura and Los Angles Counties (2 to 5 degrees).

Forecast is still on track. Winds are currently gusting 40 to 50 mph for LA County mountains and the Antelope Valley. The gusty winds are expected to expand across the Ventura mountains, and the Santa Barbara south coast and mountains tonight.

***From Previous Discussion***

Sprinkles/showers are expected to last no longer than 3-4 hours in any one location. Storms like this that move inland over northern California and move south along the Sierra spine typically result in lighter rainfall amounts locally, and especially from southeast Santa Barbara to western LA County due to downsloping flow off the Transverse range. There may be a little reinforcing southwest flow over southeastern LA County that will generate slightly higher rain rates there and especially in the eastern San Gabriel Mountains, but amounts there should top off at around a half inch. Snow levels along the frontal boundary are way up above 8000 feet so only the highest peaks will see any frozen precip.

All the precip will be out of the area before the sun rises Sunday, except for possibly some lingering light showers on the north facing slopes Sunday morning. Otherwise, clearing skies expected with plenty of sunshine but temperatures well below normal.

The storm is generating some gusty westerly winds that will continue into Sunday, and will be strongest in the mountains and Antelope Valley.

Dry and warmer weather expected Monday and Tuesday, but with some gusty northerly winds at times, especially southern Santa Barbara County and the I5 corridor.

.LONG TERM (WED-SAT)...04/221 PM.

A slow warming trend is expected to continue through next week, but with some uncertainties later in the week and next weekend as some model solutions show a weak upper low developing over northern California. The only expected outcome from this would be slightly cooler temperatures than currently predicted. Otherwise, with the exception of daily north winds across the mountains and southern Santa Barbara County, weather conditions are expected to low impact with highs near to slightly above normal levels by mid week.

AVIATION
05/0223Z.

At 01Z at KLAX, there was no marine layer nor inversion.

Low to moderate confidence in TAFs. Light showers will be possible across the area through tonight, with VFR conditions expected after around 14Z. Confidence in timing of flight category changes will be low, and wind speeds may be off by +/- 5 kts during peak winds. Wind directions may be variable, especially during wind shifts and periods of wind below 10 kts.

KLAX...Moderate confidence in TAF. Cigs may bounce between BKN025-BKN040, and will likely be BKN050 or higher by around 11Z-14Z. No significant easterly wind component is expected.

KBUR...Low confidence in TAF. Cigs may bounce between BKN015-BKN040, until becoming BKN050 or higher by around 10Z-13Z.
Much uncertainty with regards to wind direction as wind shift from 14Z-19Z.
