12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 904 AM PDT Sun May 31 2020
SYNOPSIS. 31/903 AM.
Partly to mostly cloud skies will prevail over the region today. Varying amounts of night and morning low clouds should affect mainly the coast tonight into the middle of the week. Otherwise partly to mostly cloudy skies will prevail through the period. Temperatures will turn warmer to near normal today and to several degrees above normal Monday into mid week.
SHORT TERM (TDY-TUE). 31/856 AM.
The marine inversion was well-defined and near 2400 ft deep at VBG early this morning. However, at LAX there was a very weak inversion if you can call it that somewhere around 2500-3000 ft deep. Low clouds were much more organized N of Point Conception this morning and covered much of the Central coast, Santa Ynez Vly and into the northern SLO County interior vlys. S of Point Conception, low clouds were primarily over the eastern SBA County S coast into the VTU County coast and some vlys, as well over Santa Catalina Island. Patchy low clouds were noted in the San Gabriel Vly as well. Otherwise, sunny to partly cloudy skies were noted across the region. The low clouds are forecast to clear back to or off the coast by late this morning. However, plenty of mid and hi level clouds to the W and SW of the forecast area this morning will move into the region thru this afternoon to leave mostly cloudy skies overall.
There will be decent onshore gradients this afternoon (e.g. NAM fcst LAX-DAG +7.9 mb at 00Z) to help bring breezy to gusty NW to SW winds to many areas. Despite the cloud cover, temps are still forecast to turn warmer today back to near normal for the most part. Highs in the warmest vlys and lower mtns should reach the upper 70s to lower 80s.
A broad upper level trof will develop over the E Pac just off of the CA coast through tonight, with S to SW flow aloft over the forecast area. On Mon, a 572 dm H5 low will develop at the base of the upper trof about 300 NM SW of Point Conception. The upper level low should then remain nearly stationary Mon night thru Tue. This will allow H5 heights to increase over swrn CA from about 577-580 dm Mon afternoon to around 581-584 dm Tue afternoon.
An inversion around 1000 ft deep will develop tonight into Mon morning, and a weak eddy is forecast over the SoCal Bight. It looks like more low clouds will develop along the coast and perhaps into some adjacent vlys altho there should be northerly canyon winds along the SBA County S coast which should keep low clouds away from there. It looks like the marine inversion will lower to near surface-based S of Point Conception Mon night into Tue morning, while remains about 1000 ft deep along the Central Coast. Marine layer clouds should affect the immediate Central Coast Mon night into Tue morning, but should be patchy at best S of Point Conception. If any low clouds sneak into the L.A. County coast Tue morning they could be accompanied with some dense fog. Otherwise, there will be plenty of mid and hi level clouds moving into swrn CA tonight thru Tue to keep mostly cloudy skies for the most part over the region, except some clearing should develop over SLO/SBA Counties Tue afternoon.
Onshore gradients will decrease thru Tue, but there will still be breezy SW-NW onshore winds each afternoon and evening for many areas. The NAM was also forecasting gradients from SBA-SMX to peak at -2.9 mb at 06Z this evening. This will contribute to gusty sub- advisory NW to N sundowner winds for the SBA County S coast and Santa Ynez Mtns mainly W of Goleta this evening.
Temps are forecast to turn even warmer Mon thru Tue despite the presence of mid and hi level clouds over the region. This is due to a combination of weaker onshore gradients and increased boundary layer/950 mb temps. It looks like highs in the warmest vlys and lower mtns will reach the Mid 80s to near 90 on Mon, and upper 80s to low 90s on Tue. High temps by Tue will be about 3-8 deg above normal away from the coast.
LONG TERM (WED-SAT). 31/347 AM.
Both the GFS and the EC agree the upper low will not move much on Wednesday. But the mid and high level clouds should move away and it should be a sunny day. The sunshine will add another 3 to 6 degrees of warming to the area and Wednesday will be warmest day of the next 7 with all of the vlys in the 90s and coastal areas mostly in the 80s away from the beaches.
On Thursday both models promise to move the upper low to the east towards Baja. There are still differences however. The GFS places the center of the low about 100 miles further east than the EC does. Whichever mdl is correct or if it a compromise between the two it probably will not make too much of a difference in the forecast for Srn CA. Look for partly cloudy skies everywhere and morning low clouds across the coasts. The hgts will lower through the day and this will kick off a cooling trend.
Both mdls now suggest that the upper low be pulled up to the north and east as it becomes entwined in the flow around a large PacNW low. This will move the upper low over the area Thursday night (GFS) or Friday morning (EC). This passage will generate a slight chc of mtn showers again earlier GFS and later EC. Friday will start out a little cloudy but will then clear in the afternoon the lower hgts will accelerate the cooling trend and max temps should drop 5 to 10 degrees. Max temps will end up only 1 to 3 degrees above normal across the coasts and 2 to 5 degrees blo normal over the vlys and interior.
Dry WSW flow on tap for next Saturday. Look for mostly sunny skies as the low's passage will likely disrupt the marine layer. max temps will warm a few degrees with rising hgts.
AVIATION. 31/1200Z.
At 1100Z at KLAX, There was no marine layer nor any inversion.
Low to moderate confidence in TAFs. Stratus is not well organized especially south of Point Conception so clouds may clear occasionally. For KPRB/KSMX/KSBP, good confidence in IFR/LIFR cigs with a 50% chance of VLIFR conditions. South of Point Conception, good confidence in IFR/low MVFR cigs for coastal/valley sites where cigs are forecast. For LA County coastal sites, there is a 40% chance of no cigs.
KLAX . Low to moderate confidence in TAF. There is a 40% chance of no cigs. Good confidence that any east wind component will be under 4 kt.
KBUR . Low to moderate confidence in TAF. There is a 50% chance of IFR cigs. Clearing of cigs may occur as early as 14Z.
MARINE. 31/800 AM.
Across the outer waters . Winds will be elevated and gusty to Small Craft Advisory (SCA) level beginning this morning near Point Conception and across all of the outer waters by this afternoon. The winds will diminish after midnight to below SCA level then will increase to SCA level again tomorrow with similar timing. Conditions across all of the outer waters will be below SCA levels Tuesday through at least Wednesday then there is a sixty percent chance of the wind increasing to SCA level again on Thursday.
Across the nearshore waters of the Central Coast . Winds will increase to SCA level this afternoon and evening, otherwise conditions will be below SCA levels through at least Thursday.
Across the inner waters south of Point Conception . Winds will increase to SCA level from Point Conception to Point Mugu this afternoon and evening and will be elevated but below SCA level south of Point Mugu during the same period. Otherwise, conditions will be below SCA levels through at least Thursday.
A long period south swell will gradually subside but will increase again later in the week.
