Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 827 PM PDT Thu Apr 25 2024
SYNOPSIS
25/213 PM.
Strong onshore flow and a deep moist layer will keep temperatures cooler than normal across Southwest California through Friday.
There should be some showers on the north mountain slopes Friday into Saturday morning, otherwise dry weather can be expected along with gradually warmer temperatures this weekend into the middle of next week.
.SHORT TERM (THU-SUN)...25/827 PM.
***UPDATE***
Latest satellite/surface observations indicate a chaotic cloud pattern, ranging from clear to cloudy with most clouds across Ventura/LA counties. Deep, but weak, inversion caps a moist layer around 5000 feet deep. Some breezy west to northwest winds, gusts 25-40 MPH, are currently observed with the strongest gusts across the Antelope Valley foothills and the western Santa Ynez Range.
Overall for the immediate short term, main issue will be the winds. Overnight, expect northwesterly winds to increase in coverage and intensity across the area. Strongest winds are likely through the I-5 Corridor, but gusty winds will impact the rest of the mountains and the Antelope Valley. Current spate of wind products (warnings and advisories) across the the mountains and Antelope Valley look on track. See LAXNPWLOX for the latest details on the various wind products. Along with the wind, the northwesterly flow will bank up moisture across the northern mountain slopes. So, there is a chance of some light showers in these areas overnight. Snow levels look to remain rather high, above 6500 feet overnight, so no issues are anticipated for the Grapevine area.
Overall, current forecast has good handle on the immediate short term. So, no significant updates are anticipated at this time.
***From Previous Discussion***
A deep moist layer continued into early this afternoon over the forecast area, with plenty of lingering stratocu altho there were some breaks here and there. The clouds are expected to scatter out a bit more thru the afternoon for much of the coast and a few adjacent vlys, but overall should linger for much of the coastal slopes and inland vlys.
Gusty mainly sub-Advisory level NW to N winds are expected to affect the Central Coast, the southwestern SBA County mtns and coast, the Antelope Vly including foothills, and the L.A. County mtns along the I-5 Corridor thru the afternoon hours. Otherwise, breezy onshore winds can be expected this afternoon.
A cool air mass from a departing upper level trof will result in afternoon temps being about 6-12 deg below seasonal norms. Highs should only be in the 60s for much of the coast, vlys and deserts.
Weak upper level ridging thru this evening will be replaced by upper level troffiness later tonight, with a stronger upper level trof moving in from the6/00 +8.3 +9.8 -1.5 -1.9 +2.4 -2 +1.4 + 2 -0.5 +4.2 +3.4 +12.9 N on Fri. This upper level trof will linger over SW CA Fri night before exiting to the E on Sat. Upper level ridging should then start to build into the area Sat night and Sun, with H5 heights increasing to around 576-577 dam Sun afternoon.
The main story of the upper level trof will be the winds. Strong and gusty NW to N winds will cover much of the interior areas tonight thru Fri night or Sat morning, as well as the SW SBA County coast and mtns, where a series of Wind Advisories and High Wind Warnings/High Wind Watches will be in effect. Gusts of 40 to 65 mph will be possible, strongest in the mtns. Gusty Advisory level winds will also be possible for the Santa Clarita Vly and along the Central Coast Fri afternoon into Fri night, where Wind Advisories may be needed. Please see the latest Non-Precipitation Weather Message (LAXNPWLOX) for further details.
Partly to mostly cloudy skies will persist tonight into Friday, then be mainly on the N slopes Fri night into Sat morning, with a slight chance to chance of showers and snow showers mainly on the N mtn slopes. Mostly sunny skies can then be expected in all areas Sat afternoon.6/00 +8.3 +9.8 -1.5 -1.9 +2.4 -2 +1.4 + 2 -0.5 +4.2 +3.4 +12.9
Marine layer low clouds and fog are expected to develop along many coastal areas into some adjacent vlys Sat night into Sun morning, otherwise mostly clear skies can be expected for the second half of the upcoming weekend.
Temps are forecast to be several degrees below normal on Fri then warm to near or slightly above normal by Sun. Temps over the inland coast and vlys should reach the upper 60s to low 70s Fri, the 70s on Sat, and in the 70s to around 80 on Sun.
.LONG TERM (MON-THU)...25/209 PM.
The EC and GFS deterministic and mean ensembles are in generally good agreement during the extended period. Weak and mostly flat upper level ridging will prevail over the region Mon and Tue, followed by weak upper level troffiness Wed and especially Thu.
Dry weather will prevail over the forecast area Mon thru Thu. The marine layer pattern is expected to continue thru the period, with varying amounts of night and morning low clouds and fog along portions of the coast Mon and Tue, then expand along the coast and extend inland to the adjacent vlys Wed and Thu. Otherwise, skies will be mostly clear.
Temps are expected to be near normal to a few degrees above normal on Mon, then increase to several degrees above normal for many areas away from the immediate coast Tue and Wed. It should turn cooler in all areas Thu with temps slightly below normal for most areas, and a few degrees above normal for some interior areas.
