Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 527 AM PDT Sun Jul 25 2021

SYNOPSIS. 25/320 AM.

High pressure aloft will weaken through Monday prompting a cooling trend, but an easterly wave will bring increasing monsoonal moisture along with muggy conditions, especially on Monday. Showers or thunderstorms are possible this afternoon through Tuesday, especially on Monday when any area could see moderate to heavy showers.

SHORT TERM (TDY-TUE). 25/318 AM.

Synoptically, high pressure aloft will be sitting across the Great Basin, while an area of low pressure over Arizona continues to rotate westward towards Southern California today through Monday evening. mid level moisture is already moving into the forecast area with some virga indicated from radar as there has been no measurable rainfall hitting the ground, or at least into any rain gauges. Along the coast the marine layer was around 1100 ft deep late last evening. With the marine layer stratus covering much of the Central Coast and nosing into the Santa Ynez Valley. However, with the marine layer this deep, some low clouds were expected to affect some coastal valleys such as San Fernando and San Gabriel Valley. However this easterly push of mid to high level clouds from earlier thunderstorms across Arizona, have caused low clouds to have a tough time getting organized. There could be some patchy low clouds, but not expecting low clouds to become widespread. As the mid level debris clouds continue to move west, this could also affect the marine layer stratus along the coast this morning and could scour out earlier than usual.

For today, there will be increasing mid to high level clouds with some isolated showers across L.A. County and possibly the Ventura County Mountains. Although PWAT values will reach around 1.40" today, there is not much instability associated with the leading edge of the moist layer moving in today as there is little in the way of lift to bring any significant showers to the area. maybe a few big drops, and an occasional shower that can occur just about anywhere in L.A. County today and the Ventura County Mtns. By late tonight into Monday, the bulk of the deep moist mid level moisture will become more organized as models continue to show good vorticity advection with the upper low. PWAT values are projected to increase to between 1.50-2.00" by Monday. The monsoonal front (850 mb dewpoints) which start above 8 degrees Celsius. will increase to an impressive 12-15 degrees Celsius making it feel like the deep south on a humid day. Latest Cross sections also identify good upward lift as relatively strong Omegas move across L.A. /Ventura Counties during the day, then into Santa Barbara County late Monday. Showers will become more widespread across L.A. and Ventura Counties, then spreading into Santa Barbara County late Monday morning or afternoon.

Some of the showers could be moderate to heavy at times, especially over the Los Angeles and Ventura County Mountains, as well as the Antelope Valley, where the moisture and instability are the greatest. As a result, there is a slight risk for isolated flash flooding there with heavy 15 to 30 minute rainfall rates possible. While the instability needed for thunderstorms is fairly minimal, if any thunderstorm forms and taps into that moisture, the flooding threat will increase. Those near recent burn areas in the mountains should stay aware of the weather on Monday, even if the chances for debris flows are small they are above zero.

By Monday evening as the moisture continues to push west and then north towards San Luis Obispo County, will add slight chance for showers or thunderstorms into San Luis Obispo County while residual showers continue across much of the forceast area Monday evening. Showers will taper off overnight into Tuesday as the upper low will remain off the coast. High pressure will strengthen across the center of the CONUS and expand westward. This will bring increasing H5 heights and skies will be mostly clear. Except there will be enough mid level moisture across L.A. County Mtns along with 850 mb Dewpoint temps remaining quite high at 10-13 degrees C. The 00z and 06z soundings over the L.A. and eastern Ventura County Mtns continue to show decent CAPE values and instability to justify a slight chance for showers and thunderstorms. Steering SE winds should be strong enough to limit any potential flash flooding, but if storms do initiate, there could be brief heavy showers that could cause some local road and desert road flooding.

As for temperatures, High temps on Sunday and Monday should be somewhat lower due to the increasing cloud cover. However the added humidity, especially on Monday will bring little relief to the region. The usual onshore winds will be disrupted on Monday as weak offshore flow is likely across inland areas with weak winds along the coast. High temps will bounce back Tuesday, especially across inland areas 10-15 degrees, while coastal areas will rise 2 to 8 degrees, best warming along the Central Coast.

LONG TERM (WED-SAT). 25/445 AM.

High pressure aloft will continue to dominate the center of the Country this week but also affect the west as the high continues to expand westward Wednesday through Thursday. High temps are expected to reach 3-5 degrees above normal on Wednesday and remain that way much of the week. Triple digit heat will affect the Antelope Valley during the long period, and reach the mid to upper 90s in the warmest valleys.

The orientation of the upper high will become more tilted SE to NW (Negative Tilt) by Thursday and SE flow will allow for the potential of more mid level moisture to be drawn into SE California and possibly into the forecast area late this week. The EC and GFS were picking up on some inverted troughs associated with the upper high rotating into the forecast area bringing another shot of monsoonal showers and thunderstorms into L.A. and Ventura Counties by Saturday.

AVIATION. 25/1227Z.

At 12Z, the marine layer was around 1900 ft deep at KLAX. The top of the inversion was around 3400 ft with a temperature of 23C.

Low clouds were mainly confined to coastal areas, but have spread locally into the San Gabriel Valley and the Santa Ynez Valley. Conds were mostly IFR to VLIFR, except MVFR across coastal sections of L.A. County. Low clouds should clear by mid to late morning, except early afternoon on coastal sections of VTU and southern SBA County and Ventura County. Low clouds are expected in most coastal areas tonight, with IFR to VLIFR conds, except MFVR conds across coastal sections of L.A. County.

Between 20Z and 04Z, there is a low (10-20 percent) chance of showers and thunderstorms in the mtns of L.A. and VTU Counties and the Antelope Valley. at desert terminals. After 09Z, there is a slight chance of showers across L.A. County with a very slight chance of tstms.

KLAX . Moderate confidence in the 12Z TAF. There is a 20-30% chance that low clouds will scatter out as early as 15Z this morning. There is a 20-30% chance of no low clouds tonight.

KBUR . High confidence in the 12Z TAF with VFR conds expected through the pd.

MARINE. 25/517 AM.

Winds and seas will very likely remain below Small Craft Advisory (SCA) levels through at least Wed or Thu.

Patchy fog, locally dense at times will continue into next week. The poorest visibility and most widely spread conditions will occur in the overnight and morning hours along the Central Coast.

A weak upper-level trough over southern Arizona will retrograde to the southwest today, then move across the offshore waters through early next week. Isolated to scattered showers and thunderstorms could develop today across southern sections, then spread northward overnight and Monday. Any thunderstorm may produce local gale force winds and rough seas, dangerous lightning, heavy rainfall with reduced visibility, and waterspouts.

LOX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . NONE.

.HAZARD POTENTIAL OUTLOOK (TUE-SAT).

Showers and thunderstorms are possible on Tuesday, primarily in the mountains and deserts, with dangerous lightning and heavy showers possible.
