Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 400 PM PST Thu Jan 23 2020

SYNOPSIS. 23/751 AM.

High pressure will keep the area dry through Saturday with slightly above normal temperatures. A very weak cold front will bring increasing cloudiness and a slight chance of rain to mainly northern areas Sunday, along with a return to normal temperatures. Dry and breezy conditions are expected Monday through Wednesday with above normal temperatures.

SHORT TERM (TDY-SUN). 23/118 PM.

Lots of 70s today, even some across parts of the Central Coast. Expecting more of the same Friday and Saturday, though possibly just very slight cooling near the coast as offshore gradients are a little weaker. There is some stratus off the coast and a few patches moving onshore between LAX and Palos Verdes but otherwise mostly clear skies today. Some patchy dense fog is possible across interior SLO later tonight as moisture tries to push in from the Central Valley.

The upper ridge responsible for this warm/dry weather is expected to shift east Sunday allowing a weak trough to move in from the west. This will mostly stay north of us but like so many have done this month some clouds and isolated light precip are possible near the Kern County line from southeast SLO County through the Grapevine. The trough will also temporarily shift gradients back onshore leading to several degrees of cooling Sunday as well as a likely return of the marine layer south of Pt Conception.

LONG TERM (MON-THU). 23/143 PM.

Following the Sunday trough weak ridging will return through mid week and then much stronger ridging for the latter half of the week. Strong northwest flow is expected Monday through at least Wednesday with advisory level winds possible at times over the Grapevine and surrounding mountains as well as srn SB County. Temps will warm a few degrees through mid week with additional warming, possibly close to 80 degrees in some of the warmer valleys by the end of the week. Looking longer range models still in good agreement showing little to no precip through at least the first 10 days or so in Feb.

AVIATION. 23/2358Z.

At 2355Z, the marine layer was 400 feet deep at KLAX. The inversion topped out at 1200 feet and 19C.

Moderate confidence in the current forecast. VLIFR to LIFR conditions at KPRB are likely between 12Z-17Z Fri. VFR conditions should continue at remaining terminals, with only a 10-20 percent chance of VLIFR/LIFR cigs/vsbys overnight into early Friday morning at coastal terminals south of KSBA.

KLAX . Moderate confidence in the 00z TAF. There is a 20 percent chance of VLIFR to LIFR cigs/vsbys at KLAX between 11Z-16Z. Otherwise, VFR conditions are expected through the period. Any east winds will remain less than 6 knots.

KBUR . High confidence in the 00z TAF. VFR conditions are expected through the period.

MARINE. 23/1236 PM.

For the Outer Waters, high confidence in the current forecast. Seas will be below SCA levels today, then winds and seas will deteriorate tonight through Friday. High confidence in both SCA level northwest winds and SCA level seas developing. There is a 40 percent chance of gale force winds on Monday.

For the Inner Waters north of Point Sal, moderate-to-high confidence in the current forecast. For today through early Friday, winds and seas will remain below SCA levels. There is a 50 percent chance of SCA northwest winds and SCA level seas on Friday afternoon and night, increasing to 80 percent Saturday through Monday.

For the Inner Waters south of Point Conception, moderate-to-high confidence in the current forecast. Winds and seas are expected to remain below SCA levels through Saturday. There is a 30 percent chance of SCA level winds on Saturday evening across the Santa Barbara Channel. For Sunday and Monday, there is a 70-80 percent chance of SCA level west to northwest winds developing.

BEACHES. 23/151 PM.

High surf could redevelop Friday and Friday night at all beaches, so a High Surf Advisory has been issued this afternoon. Even larger surf is possible late Sunday through Tuesday.

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.
