Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 804 PM PDT Tue May 26 2020

SYNOPSIS. 26/715 PM.

Afternoon temperatures will be well above normal over inland regions through Thursday. Most coastal locations will stay cooler due to persistent areas of overnight and morning low clouds and dense fog, some of which may linger into the afternoon. Temperatures will cool to near normal by Sunday.

SHORT TERM (TUE-FRI). 26/803 PM.

***UPDATE***

Another quiet evening across the forecast district. Latest satellite and surface observations indicate widespread stratus/fog south of Point Concpetion over the coastal waters and immediate coastal plain. Otherwise, skies are clear. Latest sounding data indicates marine inversion ranging from 600 feet north of Point Conception to around 900 feet south of Point Conception.

For the immediate short term, main forecast issue is the extent of the stratus/fog. Do not anticipate much deepening of the inversion overnight, so stratus/fog should remain confined to the immediate coastal plain (especially south of Point Conception). Given the shallowness of the inversion, dense fog will be an issue overnight. At this time, not sure how widespread any dense fog will be. So, will hold off on any advisories with the evening update, but would not be surprised if an advisory is needed later tonight and Wednesday morning.

Overall, forecast looks very good for the immediate short term. So, no significant updates are planned at this time.

***From Previous Discussion***

A solid stratus layer has formed underneath a shallow but very strong coastal inversion based from 300-500'. Low clouds and fog continue to hug much of the coastline south of Pt Conception but some additional clearing is expected through early evening. A light onshore flow in place today with the marine layer is keeping coastal areas (and up to 15 or so miles inland) relatively cool and will likely stay that way through the week. In fact, gradients trend more onshore each day through Friday so if anything clouds will be even more stubborn at the coast than today. Above the marine layer, and for most of the valleys and other inland areas temps are soaring into the 90s and should continue to do so through at least Thursday. Temps are hottest across interior SLO County and the Antelope Valley but even the western portion of the San Fernando Valley will get close to 100 each of the next couple days. This is creating a huge temperature gradient over a short distance with temps in the 60s at foggy beaches and high 90s just over the Santa Monicas into Woodland Hills. Impressive but actually not that uncommon, especially early in the warm season when stratus is a very persistent and influential feature at the coast. Dense fog over the bight region will move inland overnight and dense fog advisories may be needed in at least some of the coastal zones by later tonight or early Wednesday.

The only real adjustment to the forecast was to lower coastal temps a few degrees as it's become evident that the GFS's stronger onshore gradient forecasts from the past week or so are panning out keeping the coast cooler. We should also see the low clouds eventually pushing north along the Central Coast but that likely will have to wait until Wednesday night or Thursday.

Pretty high confidence now in a widespread cooling trend by Friday. Coastal valleys will see some cooling as early as Thursday but much more so Friday and including the interior as well as onshore gradients increase to 9-11mb and there's enough cooling aloft to help lift the inversion and bring the cooler air inland. We may need a wind advisory for the Antelope Valley towards the end of the week with those stronger gradients generating gusty southwest winds.

LONG TERM (SAT-TUE). 26/217 PM.

Models in good agreement showing the cooling trend continuing into the weekend and early next week as a pretty deep trough develops along the west coast. The initial upper low, currently located near 27n/140w, or about 800 miles southwest of LAX, may get close enough to generate some light precip across far western SLO/SB Counties early Saturday. More uncertainty on the second upper low for late Monday and Tuesday but both model ensembles have a few solutions that support some light precip even as far south as LA County. Main impact will be the cooler temps with highs dropping back to normal levels as early as Sunday.

AVIATION. 26/2332Z.

At 2230Z, the marine inversion at KLAX was based at 900 feet. The top of the inversion was 2300 feet with a temperature of 26 degrees Celsius.

Overall, moderate confidence in 00Z coastal TAFs and high confidence in valley/desert TAFs. High confidence in shallow marine inversion brining LIFR/VLIFR conditions to coastal TAFs south of Point Conception this evening and overnight, but moderate confidence in timing of flight category changes. Only moderate confidence in LIFR/VLIFR conditions for KSMX overnight.

KLAX . Overall, moderate confidence in 00Z TAF. High confidence in CIG/VSBY restrictions this evening into Wednesday morning, but only moderate confidence in timing of IFR/LIFR category changes. Timing of dissipation of CIG/VSBY restrictions could be +/- 2 hour of current 1730Z forecast. No significant easterly wind component expected.

KBUR . High confidence in 00Z TAF as CAVU conditions are anticipated through TAF period.

MARINE. 26/803 PM.

Overall moderate to high confidence in current forecast. For all the coastal waters, high confidence in winds and seas remaining below Small Craft Advisory (SCA) levels through Saturday. On Sunday, there is a 70% chance of SCA level winds across the Outer Waters and a 40% chance of SCA level winds across the western half of the Santa Barbara Channel.

Areas of dense fog with visibility one nautical mile or less at times are likely tonight through Wednesday morning for the waters south of Point Conception. A Marine Weather Statement has been reissued and will remain in effect through Wednesday morning. Mariners should be prepared to reduce speeds and use GPS navigation if available.

LOX WATCHES/WARNINGS/ADVISORIES. CA . Heat Advisory in effect until 7 PM PDT Thursday for zone 37. (See LAXNPWLOX). Excessive Heat Warning in effect until 7 PM PDT Thursday for zone 59. (See LAXNPWLOX). PZ . NONE.

.HAZARD POTENTIAL OUTLOOK (FRI-TUE).

Strong winds are expected in the Antelope Valley and surrounding foothills Friday and Saturday.
