Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 851 AM PDT Fri Jul 10 2020
SYNOPSIS. 10/227 AM.
High pressure over the Four Corners region will expand westward through Sunday. This will bring a warming trend to Southwest California with temperatures well above normal on Saturday and Sunday. The high pressure will weaken early next week, bringing cooler temperatures to most areas, and a return of coastal low clouds and fog by mid-week.
SHORT TERM (TDY-SUN). 10/845 AM.
The marine inversion early this morning ranged from near surface- based at VBG to around 1200 ft deep at LAX. Low clouds and fog covered the much of the coast especially S of Point Conception, and extended locally into some of the vlys in VTU/L.A. Counties. The low clouds are expected to clear to or off the coast by mid to late morning, with some low clouds possibly lingering at a few beaches into the afternoon. Otherwise, mostly sunny skies with a few hi clouds at times will prevail across the forecast area today.
The NAM was forecasting pressure gradients from LAX-DAG to be around +7.3 mb late this afternoon. These good onshore gradients will help to bring breezy to gusty S to W winds to the region this afternoon into early evening, with the highest gusts expected in the Antelope Valley and adjacent foothills.
Temps across the forecast area today are expected to warm to about 3- 8 deg above normal away from the immediate coast, with the warmest vlys and lower mtns reaching the 90s to around 100, except 100-104 in the Antelope Vly.
A large and increasingly strong upper level high pressure system will build over AZ/NM into the weekend. Southern CA will be under the western periphery of the upper level high, with H5 heights over southwestern CA increasing to 593-595 dm today, and to 596-597 dm on Sat before lowering slightly to around 594-595 dm for Sun.
The strong upper level ridging into srn CA will shrink the marine layer depth down to about 600 ft or less tonight thru Sun morning. Marine layer low clouds and fog should only affect portions of the SBA County Central coast and L.A. County coast tonight and Sat morning, and perhaps just the L.A. County coast late Sat night into Sun morning. Otherwise, mostly clear skies can be expected thru Sun with just a few hi clouds at times.
Boundary layer, 950 mb and 850 mb temps will warm significantly thru Sun as well. As a result, surface temps will warm significantly thru the period, with very warm overnight lows in the 70s to around 80 this weekend especially in the foothills, lower mtns and deserts. Highs will be about 4-10 deg above normal on Sat, and about 6-12 deg above normal on Sun. The warmest vlys and lower mtns should reach the upper 90s to 104 Sat, and 100-106 on Sun. The Antelope Valley will be even hotter each day, and could reach as high as 105-110 degrees on Sun.
Due to the hot daytime temps and very warm overnight lows, a Heat Advisory is in effect for the SLO County interior valleys and mtns, the Cuyama Vly, and the L.A. County vlys and mtns from late Sat morning thru early Sun evening. In addition, an Excessive Heat Watch is in effect for the Antelope Valley for Sun. Please see the latest Non-Precipitation Weather Message (LAXNPWLOX) for further details on the Heat Advisories and Excessive Heat Watch.
Onshore gradients (LAX-DAG) are forecast by the NAM to weaken Sat to +6.7 mb in the afternoon, then increase to +8.2 mb Sun afternoon. Breezy S to W winds are expected to persist for many areas during the afternoon and evening hours. Light offshore flow will be possible night and morning hours over SLO/SBA Counties and interior VTU County as well thru the weekend.
LONG TERM (MON-THU). 10/312 AM.
Both the GFS and the EC agree that the upper high will be pushed to the south and east on Monday by a large and broad trof moving into the PAC NW. From Tuesday through Thursday weak troffing will be over the west coast. Hgts will fall from 592 DM Monday to 588 DM Wed and Thu.
Most importantly there will be a jump in onshore flow both to the north and the east. Afternoon grads will be near 9 mb to the east and between 6 and 7 mb to the north. This increase in onshore flow along with the decreasing hgts and cyclonic flow will allow the marine layer cloud pattern to reform. Such strong afternoon grads may prevent clearing at some of the beaches and will also bring stronger than normal westerly winds to the area.
Max temps will fall each day Mon through Wed and then change little on Thu. Tuesday will see the biggest drop in temps: 3 to 7 degrees. Max temps will be below normal Wed and Thu.
AVIATION. 10/1216Z.
At 1100Z at KLAX . The marine layer was 700 feet deep. The top of the inversion was near 2400 feet with a temperature of 26 degrees Celsius.
Moderate confidence in coastal TAFs through 21Z, and good confidence afterward and for remaining TAFs. There is a 30% chance that coastal sites south of Point Conception may briefly lower into LIFR. Forecast flight cat changes excluding the VFR transition could be off by +/- 1 hour. VFR transition could be off by +/- 2 hours.
KLAX . Moderate confidence in TAF through 21Z. There is a 30% chance that cigs may lower to LIFR briefly. VFR transition could occur anytime between 18Z and 22Z. Good confidence that any east wind component will be 3 KT or less.
KBUR . High confidence in CAVU TAF.
MARINE. 10/849 AM.
Across the outer waters . Winds will be elevated and gusty to Small Craft Advisory (SCA) level across the northern outer waters beginning today and across the remainder of the outer waters beginning Saturday afternoon. The elevated winds will continue through Monday, mostly in the afternoon and evening hours. Otherwise and elsewhere, conditions will remain below SCA level.
Across the nearshore waters of the Central Coast . There is a thirty percent chance of SCA winds Saturday night through Sunday night, otherwise conditions will remain below SCA level.
Across the inner waters south of Point Conception . Winds will increase to SCA level Saturday through Monday from Point Conception to Point Mugu, mostly in the afternoon and evening hours. Otherwise, conditions will be below SCA level.
Steep, hazardous seas will develop across the coastal waters through the coming week.
LOX WATCHES/WARNINGS/ADVISORIES. CA . Heat Advisory in effect from 11 AM Saturday to 8 PM PDT Sunday for zones 37-38-46-51-54-88-547. (See LAXNPWLOX). Excessive Heat Watch in effect from Sunday morning through Sunday evening for zone 59. (See LAXNPWLOX). PZ . Small Craft Advisory in effect until 3 AM PDT Saturday for zone 670. (See LAXMWWLOX).
.HAZARD POTENTIAL OUTLOOK (SUN-THU).
Hot temperatures will affect the coastal and interior valleys of southwest California Sunday through Monday. Moderate to high heat risk will be possible. Additionally, there will be elevated fire weather conditions away from the coast.
