Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 512 AM PST Mon Nov 30 2020
SYNOPSIS. 30/512 AM.
Skies will be clear through Wednesday and it will be breezy to locally windy. Daytime highs will be well above normal in most areas. A moderate to possibly strong offshore wind event will affect the region Wednesday night through Friday, along with some cooling. Winds should decrease over the weekend, with some warming expected.
SHORT TERM (TDY-WED). 30/509 AM.
Just some high clouds drifting across the region this morning, and those should push east of the area by late morning. The KLAX to KDAG gradient was 3.4 mb offshore this morning, almost unchanged from this time on Sun. There was less in the way of winds across the mtns and valleys of L.A./VTU Counties early this morning. While winds may increase and become a more widespread with the typical diurnal cycle this morning, expect winds to remain below advisory levels today. Winds should diminish in most areas this afternoon, A very weak short wave trough will zip southeastward across the region this morning. It will not change heights or thicknesses much, but it will turn the flow aloft more northerly. Max temps today should actually go up a couple of degrees in most areas from those recorded on Sun, due to some warming at 950 mb.
N-S gradients will begin to sharpen later today and tonight, especially between KLAX and KBFL and KSBA and KBFL. where gradients will top out between 5 and 6 mb offshore. With this in mind, and some subsidence on the backside of the short wave, expect some gusty advisory level winds to develop across southern SBA County this evening, first in areas from Refugio westward late this afternoon and evening, with the focus of the winds shifting to areas near Montecito later in the evening through late tonight as the winds turn more north northeasterly. Also, northwest to north winds should reach advisory levels around the Interstate 5 corridor this evening, then continue tonight. The winds will shift to northeast Tue, causing the focus of the winds to shift to other mountain locations, but advisory level winds should persist in the L.A./VTU County mtns for much of Tue.
With this in mind, have issued Wind Advisories from this evening through late tonight for the Santa Ynez Range and the south coast of SBA County, and from this evening through Tue afternoon for the mountains of L.A./VTU Counties (excluding the Santa Monicas).
High resolution models show winds spreading into the Santa Clarita Valley, the western San Fernando Valley, the eastern valleys of Ventura County, and into the Santa Monicas tonight, but at this point, it appears winds will mostly remain just below advisory levels. Will let the day shift look at the next high res model run to make that decision for tonight.
Winds will turn more northeasterly on Tue, and that is when advisory level winds look more likely in the Santa Clarita Valley, the northern and western San Fernando Valley, the valleys of VTU County, the Ventura County coastal plain and the Santa Monica mountains. Advisories will probably be needed for Tue for those areas. The main question is will they be needed tonight. Locally gusty northeast winds will also affect locations through and below passes and canyons of the Santa Lucia range in SLO County late tonight/Tue morning. Height/thicknesses will rise a bit more on Tue, but 950 mb temps do not change much, with warming possibly offset by low level cold advection. Therefore, expect little change in max temps Tue.
The EC, GFS and the WRF, are in decent agreement with the upper pattern, showing a highly amplified ridge extending from southern CA north northeastward into eastern portions of the Pac NW and Idaho Tue night and Wed. The GFS and EC show an enormous upper low covering much of the Plains and the eastern Rockies on Wed. At the surface, offshore pressure gradients have also come into somewhat better agreement. While the WRF had been showing KLAX- KDAG gradients of over 8 mb offshore at 12Z Wed, it now shows 6.6 mb, while the EC show a gradient of 4.2 mb offshore, and the GFS just 2.9 mb offshore. It now appears that for at least Tue night/Wed, northeast winds will be generally in the advisory level category across the mtns and most valleys of L.A./VTU Counties and the VTU County coastal plain. Max temps will likely drop a few degrees as heights lower and cold air advection begins to spill in from the northeast.
LONG TERM (THU-SUN). 30/503 AM.
Both the GFS and the EC show vigorous short wave energy wrapping around the western periphery of the expansive upper low Wed night and Thu, elongating it and pulling it westward. The EC actually shows it pinching off into another upper low in Arizona Thu afternoon, while the GFS shows it remaining a very positively titled sharp trough. The EC, (as has the GFS for the past several runs) continues to show a very sharp height gradient setting across the region Wed night and Thu between that upper low and a strong upper high over Oregon. However, the 06Z run of the GFS shows an upper low moving into the coast of northern CA, then shows it dropping southward to near Pt. Concepton Fri. This is a totally new solution and looks rather odd, so it has been discounted in favor of the 00Z run of the GFS which was similar to the EC.
While the 00Z runs of both models have backed off with respect to the strength of the sfc pressure gradient between KLAX and KDAG late Wed night/Thu, the still GFS showed 5.2 mb offshore Thu morning INCREASING to 5.7 mb in the afternoon, while the EC showed a similar trend, 5.2 mb increasing to 6.7 mb in the afternoon. With deeply layer northeasterly flow through the atmosphere and some decent cold air advection, along with moderate gradients, expect a solid wind advisory level event across much of L.A. and VTU Counties Wed night and Thu, with the potential for some High Wind Warning level winds depending upon how the pattern ultimately unfolds.
The EC shows the upper low spinning across Arizona Fri. keeping good northeast flow aloft over our area and keeps sfc gradients fairly strongly offshore. The 00Z run of the GFS actually showed the strongest offshore gradients Fri morning. Gusty northeast winds will likely persist across much of L.A. and VTU Counties Thu night and Fri. With the cold air advection and some height falls, would expect some cooling across the region for Thu/Fri.
The EC shows the upper low slowly drifting into extreme southern CA on Sat, then southward into Baja on Sun, keeping northeast flow aloft over the area. However, surface pressure gradients really drop off Sat, then even become onshore Sunday. The GFS keeps gradients offshore through the weekend, possibly strong enough to keep gusty winds going into Sat. It is a very complicated forecast as far as timing and strength of the winds, but at this point, expect the windiest days to be Thu and Fri, with an edge to Thu.
AVIATION. 30/1006Z.
At 1000Z, there was a surface-based inversion at KLAX. The top of the inversion was 800 feet with a temperature of 21 degrees Celsius.
Overall, high confidence in 12Z TAF as VFR conditions are anticipated for all sites through the period.
KLAX . High confidence in 12Z TAF as VFR are anticipated through the period. No significant easterly wind component is expected.
KBUR . High confidence in 12Z TAF as VFR are anticipated through the period.
MARINE. 30/206 AM.
For the Outer Waters, moderate to high confidence in current forecast. Today through Tuesday evening, high confidence in Small Craft Advisory (SCA) level winds and seas. For Wednesday through Friday, generally high confidence in winds and seas remaining below SCA levels although there is a 50% chance of SCA level northeast winds across PZZ676 Wednesday night and Thursday.
For the Inner Waters north of Point Sal, moderate to high confidence in current forecast. There is a 40% chance of SCA level winds each afternoon and evening today and Tuesday. For Wednesday through Friday, high confidence in winds and seas remaining below SCA levels.
For the Inner Waters south of Point Conception, moderate to high confidence in current forecast. Through tonight, high confidence in winds and seas remaining below SCA levels across most areas except for a 40% chance of SCA level winds across the western half of the Santa Barbara Channel. For Tuesday, there is a 50% chance of SCA level northeast winds south of Ventura. For Wednesday through Friday, there is a 60-80% chance of SCA level northeast winds from Ventura southward.
FIRE WEATHER. 30/411 AM.
A prolonged period of dry offshore flow will continue to bring elevated to brief critical fire weather conditions at times across much of Southwest California during the next 7 days. Through Tuesday, north to northeast winds will gust between 25 and 45 mph at times across the wind prone areas of Southwest California with the strongest winds focused across the Los Angeles and Ventura county mountains and valleys, southern Santa Barbara county (mainly during the nighttime hours), and the coastal foothills of San Luis Obispo county. Isolated Red Flag durations of 6 hours or more will be possible across the windiest foothill locations of Los Angeles and Ventura counties Tuesday. Minimum humidities between 5 and 15 percent will be common across many areas away from the beaches, along with very poor nighttime humidity recoveries in the mountains, foothills, and wind prone areas. There is the potential for a long duration moderate to strong Santa Ana wind event with possible Red Flag conditions sometime between Wednesday and Saturday. While there is still some uncertainty in the timing and strength of this event, the highest probability of the strongest and most widespread Santa Ana winds appears to be Wednesday night into Thursday.
LOX WATCHES/WARNINGS/ADVISORIES. CA . Wind Advisory in effect from 6 PM this evening to 3 AM PST Tuesday for zones 39-52. (See LAXNPWLOX). Wind Advisory in effect from 9 PM this evening to 3 PM PST Tuesday for zones 53-54. (See LAXNPWLOX). PZ . Small Craft Advisory in effect until 9 PM PST Tuesday for zones 670-673. (See LAXMWWLOX). Small Craft Advisory in effect from 3 PM this afternoon to 9 PM PST Tuesday for zone 676. (See LAXMWWLOX).
.HAZARD POTENTIAL OUTLOOK (WED-SUN).
An extended dry and warmer pattern through the week with elevated fire weather concerns, culminating in a potentially strong Santa Ana wind event with critical fire weather conditions at the end of the week.
