Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 949 AM 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-SAT). 23/935 AM.

Much warmer in most areas today as a ridge of high pressure moves over the area and gradients are lightly offshore. Highs expected to warm up into the low to mid 70s across many coast/valley locations, especially LA/Ventura Counties. Some locally breezy northeast winds in the hills and mountains but below advisory levels.

***From Previous Discussion***

A very weak short wave trough zips across the region tonight, but then ridging develops across the region once again behind this feature on Fri. Gradients stay weakly offshore, so there may still be some locally gusty winds, but expect any northeast winds to be weaker and more localized on Fri than they area today. There could be a degree of two of cooling on Fri, especially across the coastal plain. Do not expect the quick moving weak trough to really assist in developing an organized stratus layer, so expect just varying amounts of highs tonight/Fri, with possibly some local stratus/fog.

There will be some increase in N-S gradients Fri night, so there could be some gusty winds thru and below passes and canyons of the Santa Ynez Range. Otherwise, the positively tilted upper ridge will hold across the region into Sat, and W-E gradients will remain weakly offshore. Cross sections indicate that there will likely be some increase in high clouds on Sat, especially north of Pt Conception, which could knock a couple of degrees off max temps there. Otherwise, mostly minor changes in max temps are expected, generally running near to a few degrees above normal.

LONG TERM (SUN-WED). 23/350 AM.

The ridge will move to the east of the region on Sunday as a weak trough moves into the West Coast. Models have been trending weak and weaker with this system, and it now appears that it may only bring rain, (light at that), to areas north of Pt Conception on Sunday. Elsewhere, expect increasing clouds on Sunday, with some cooling.

Behind that system, ridging will return to the region, so expect dry weather Monday through Wednesday, with a warming trend. It does appear as though there could be an extended period of gusty north winds, which will probably reach at least advisory levels at times.

AVIATION. 23/1747Z.

At 1634Z, there was no marine layer at KLAX. An inversion based at 200 feet topped out at 1800 feet and 17C.

Moderate confidence in the current forecast. There is a chance of VLIFR to LIFR conditions at KPRB after 12Z Fri. VFR conditions should continue at remaining terminals.

KLAX . Moderate confidence in the 18z TAF. There is a 30 percent chance of VLIFR to LIFR conditions at KLAX after 12Z. Otherwise, VFR conditions are expected through the period. Any east winds will remain less than 7 knots.

KBUR . High confidence in the 18z TAF. VFR conditions are expected through the period. No wind impacts are expected at this time.

MARINE. 23/942 AM.

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. 23/948 AM.

High surf could redevelop Saturday and Saturday night at all beaches. There is 50-60 percent chance that a HIGH SURF ADVISORY will be needed. Even larger surf is possible late Sunday through Tuesday.

LOX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . Small Craft Advisory in effect from 3 AM Friday to 3 AM PST Sunday for zones 670-676. (See LAXMWWLOX). Small Craft Advisory in effect from 9 PM this evening to 3 AM PST Sunday for zone 673. (See LAXMWWLOX).

.HAZARD POTENTIAL OUTLOOK (SAT-WED).

There is the possibility of gusty north winds on Monday and Tuesday, especially through the Santa Ynez Range and the Interstate 5 Corridor.
