8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

SYNOPSIS. 21/1248 PM.
Little change in temperature is expected through Tuesday with night and morning low clouds and fog across the coasts and lower valleys. A slight warming trend will occur Wednesday and Thursday followed by additional warm and dry conditions this weekend.
SHORT TERM (TDY-THU). 21/131 PM.
Still warm and dry across interior sections today, which has sparked additional plume development over the Bobcat Fire in the San Gabriel Mountains and Antelope Valley foothills. Temperatures were in the 90s with many humidities between 5-15 percent. A few southwest wind gusts of 25 to 35 mph in this region will result in brief periods of critical fire weather until sunset this evening. Elsewhere, rather benign weather concerns with a marine layer that jumped up to 1700 feet south of Pt Conception and less than 800 feet to the north. Low clouds have retreated off the coast for most areas except from Gaviota westward and along the central coast this afternoon. Expect a return of stratus and locally dense fog in these areas and mainly clouds for the Ventura and LA Coasts including the LA Valleys late tonight through Tuesday morning.
Onshore pressure gradients will be slightly weaker the next few days as high pressure slowly builds into the region, so not quite as gusty across the mountains and deserts in the afternoons. Very minimal changes are expected with temperatures and humidities however, just a couple of degrees lower Tuesday then higher on Wednesday. This will continue to create some elevated fire weather concerns each afternoon when humidities drop into the lower teens. Wind direction begins to veer to the west and northwest late Wednesday which could be the first evening Sundowners returning to western hills of the south Santa Barbara County coast. Building heights will help to lower the marine inversion through Wednesday, so less inland push of low clouds but more likely to see locally dense fog for coastal areas.
On Thursday, there is a weak trough that slides across northern CA that strengthens the northwesterly wind flow heading into Friday. NW to N offshore pressure gradients of 2-3 mb develop over south Santa Barbara County Thursday evening for a potential wind advisory Sundowner by then. Not much change in temperatures yet through the short term.
LONG TERM (FRI-MON). 21/129 PM.
A storm system will pass through the Pacific Northwest on Friday and into the northern Rockies by Saturday. This helps high pressure build off the West Coast during the period with northerly flow increasing over southern CA. Warming should take place for the majority of the area with the marine layer becoming more restricted to the LA Basin by Saturday morning. Sundowner winds and I-5 corridor winds will likely add downslope warming to many areas with heights building to 592dm or higher by Saturday.
Looking beyond Saturday, the GEFS and ECMWF ensembles both hint at a significant warm up late this weekend and early next week as high pressure encompasses the Great Basin and West Coast. Heights build to 594dm or higher by Monday, which is outside of model climatology (less frequent than 1-day every 10-years) for this time of the year. The bottom-line is that we could be flirting with record temperatures once again with highs 95-105 degrees in the coastal and interior valleys, especially if we get any significant offshore wind regime (ECM deterministic shows -3mb LAX-DAG and -9mb LAX-TPH). The hot and dry scenario will likely become a headline not only for the potential heat stress and record highs, but for fire weather concerns for new and existing fires. Large plume growth would likely contribute to rapid fire growth and fire behavior.
AVIATION. 22/0006Z.
At 2308Z at KLAX, the marine layer was 1100 feet deep. The top of the inversion was around 3000 feet with a temperature of 26 C.
High confidence in desert TAFs and KPRB. Moderate confidence in coastal and valley TAFs.
Will continue with a persistent forecast overall over the next 24-hour period, except there is a 40% chance that stratus could clear out an hour earlier across coastal areas, especially N of Point Conception.
There is a 30% chance that VLIFR Conds will not occur for coastal TAF sites N of Point Conception overnight into Tue morning. There is a 20% chance that IFR Conds will continue across coastal TAF sites S of Point Conception and not increase to MVFR CIGs.
KLAX . Moderate confidence in 00z TAF. There is a 30 percent chance of marine clouds arriving +/- an hour from forecasted time. There is a 20% chance that an easterly compononet wind will exceed 8 knots between 13-18z.
KBUR . Moderate confidence in 00z TAF. There is 30 percent chance of marine clouds arriving +/- an hour from from forecasted time.
MARINE. 21/120 PM.
A Small Craft Advisory has been issued for zone 670 as wind gusts will just reach 25 knots this afternoon into tonight. Elsewhere, winds are expected to remain below SCA criteria. By Tuesday afternoon, there is a 60% chance of SCA level winds in zone 670 again with a 40 percent chance in other sections of the outer waters. Gusty NW winds will spread southward by Wednesday and there is a 70% chance of widespread SCA level winds across the outer waters through San Nicolas Island Wednesday into Thursday. Good confidence that SCA level winds will continue through Friday. There is a 30-40% chance that SCA level winds may bleed into the western portion of the Santa Barbara Channel Wednesday through Friday.
Patchy fog, locally dense with visibility of one nautical mile or less, will likely affect the coastal waters through this morning.
LOX WATCHES/WARNINGS/ADVISORIES. CA . NONE. PZ . Small Craft Advisory in effect until 3 AM PDT Tuesday for zone 670. (See LAXMWWLOX).
.HAZARD POTENTIAL OUTLOOK (THU-MON).
Strong high pressure is expected to build over the West Coast Sunday and Monday. Heat stress and elevated fire weather conditions will be possible, especially on Monday.
