Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 1131 AM PDT Thu Oct 1 2020

SYNOPSIS. 01/237 AM.

Strong high pressure along with light offshore flow will result in very hot temperatures in most areas through the end of the week. Temperatures will begin to cool slightly by Friday but will remain well above normal through the weekend.

SHORT TERM (TDY-SAT). 01/840 AM.

***UPDATE***

Almost a carbon copy of yesterday to start out with temperatures of 80 degrees to around 90 in the foothill communities and even many coastal locations (83 at Morro Bay, 84 Pismo Beach, 85 Ventura, etc.). Offshore pressure gradients is very much the same as on Wednesday morning, however, winds have backed off a little quicker in the typical windy corridors and ridges. Still have a few northeast gusts to 25 mph at Porter Ranch, Whitaker Peak, and Wiley Ridge. There is a high layer of smoke making a bigger presence across southwest CA this morning mainly from fires in the Sierra. It will be much hazier and unpleasant today due to the smoke, but really have no impact to the high temperatures. This remains a dangerous heat wave with an excessive heat warning in place through 8pm for the inland valleys where highs will reach 105-110 degrees, especially Woodland Hills and Ojai. All other areas will remain in a heat advisory through Friday with highs today well into the 90s to lower 100s. Many new record highs are anticipated today which is why it is important to take this late season heat very seriously. Reduce outdoor exercise or strenuous work during the hottest part of the day between 10am- 7pm, drink more water, and find cooling centers or an air conditioned building. Onshore pressure gradient trends will be 1 mb stronger this afternoon, so hopefully coastal areas will start to cool earlier in the evening.

There will be offshore breezes returning to most areas late tonight which will keep the foothills and ridges warm again for Friday morning. Overall, tomorrow will be a cooler day near the ocean, but remain well above normal and hot again for inland valleys.

***From Previous Discussion***

Onshore trends and slight hgt falls will bring 5 to 7 degrees of cooling to the coasts and lower vlys with 2 to 4 degrees of cooling elsewhere. Enough cooling to eliminate the excessive heat warnings but not enough to eliminate the need for heat advisories.

The ridge settles southward on Saturday and weakens some. Hgts fall to about 588 DaM. More importantly the onshore flow increases a little more. (Still not enough to bring any marine layer to the coasts) There will be 4 to 5 degrees cooling everywhere except the Central Coast which will see 5 to 10 degrees of cooling. The beaches and near coastal areas will fall to 3 to 5 degrees above normal but areas further inland will still be 10 to 15 degrees above normal.

LONG TERM (SUN-WED). 01/256 AM.

The EC no longer agrees with the GFS and now develops an oddly persistent dry upper low off of Pt Conception. This soln does not not agree with the preponderance of the ensemble forecast members and its soln was discounted.

The GFS seems much more reasonable GFS soln which calls for the west coast ridge to weaken each day Tuesday and then to move eastward Wed and Thu as an east Pac trof moves in from the west.

More importantly moderate onshore flow returns which will bring back the marine layer and the night through morning marine layer clouds. Look for another round of 4 to 8 degrees of cooling. On Monday there will be an additional 2 to 3 degrees of cooling. Temps will then not change much Tue and Wed. Even with all the cooling max temps on Monday will remain 5 to 10 degrees above normal.

If the GFS is correct in its day 7 to 10 forecast there will be substantial cooling at the end of next week as a larger trof swings through west coast bringing possible rain as far south as Monterey county.

AVIATION. 01/1830Z.

At 1714z at KLAX, there was no marine layer. There was a sfc based inversion with a top near 1400 ft with a temp of 31 C.

Clear skies with VFR conditions expected across the entire region through the period.

KLAX . High confidence in the 18Z CAVU TAF. Good confidence that there will be no east wind component greater than 5 kt.

KBUR . High confidence in the 18Z CAVU TAF.

MARINE. 01/937 AM.

For the outer waters, conds have dropped below Small Craft Advisory (SCA) levels and are expected to remain so thru early to mid afternoon. Then, SCA conds are likely this afternoon thru late into the weekend. There is a 40% chance for occasional Gale force wind gusts late Fri or Friday evening into Sat evening.

For the inner waters N of Pt. Sal, there is a 40% chance of SCA level during the afternoon and evening hours today and Sat. SCA level winds are likely during the afternoon and evening hours Fri.

For the inner waters S of Pt. Conception, there is a 30-40% chance of SCA level NW to W winds across western portion of the Santa Barbara Channel this afternoon/evening and again Fri afternoon and evening. Otherwise, SCA conds are not expected thru Mon.

LOX WATCHES/WARNINGS/ADVISORIES. CA . Heat Advisory in effect until 8 PM PDT Friday for zones 34>41-51>54-88. (See LAXNPWLOX). Excessive Heat Warning in effect until 8 PM PDT this evening for zones 44>46-547. (See LAXNPWLOX). Heat Advisory in effect from 8 PM this evening to 8 PM PDT Friday for zones 44>46-547.
