Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 156 PM PDT Mon Jun 14 2021

SYNOPSIS. 14/308 AM.

A significant heat wave is expected to be in full effect Tuesday through the remainder of the week with peak high temperatures expected Tuesday through Thursday. High temperatures will be 10 to 20 degrees warmer than normal. There will be gusty northerly winds this afternoon and Tuesday, especially across the Santa Barbara south coast and somewhat weaker through the Interstate 5 corridor. Some cooling inland by this weekend and a return of low clouds should be limited to coastal areas by Friday morning.

SHORT TERM (TDY-THU). 14/154 PM.

Overall, 12Z models in very good synoptic agreement through the short term period. Main feature of note is upper level high building over the 4 Corners area through Wednesday then weakening on Thursday which will bring some significant heat to the area.

First major concern for the short term is the potential for Sundowner winds across southern SBA county. Models continue to indicate stronger northerly gradients developing this evening and continuing through Tuesday morning. The SBA-SMX is forecast to peak around -5.0 mb and the SBA-BFl gradient at -6.5 mb. With these type of gradients, widespread advisory level winds (gusts 35-55 MPH) are likely tonight/Tuesday morning with even a chance of 60+ MPH gusts around Montecito. Given the expected winds, have issued a WIND ADVISORY for southern SBA county from 600 PM this evening through 900 AM Tuesday. For Tuesday night/Wednesday morning, the northerly gradients are weaker, but still likely strong enough to generate advisory-level Sundowner winds. So, another advisory may be needed for that time period. Otherwise, do not anticipate any significant wind issues with some sub-advisory northerly winds through the I-5 Corridor.

Other concern for the short term will be the heat. With rising H5 heights and no marine layer stratus, temperatures will skyrocket across the area. At this time, Tuesday looks to be the warmest day for a majority of the area. On Wednesday, an increase in onshore gradients will bring some slight cooling to coastal/valley areas south of Point Conception, but the Central Coast looks to warm up with some weak northeasterly flow in the morning. For Thursday, there will be some minor changes in temperatures, but conditions will still remain well above normal. So, the potential for dangerous heat will continue. Current, EXCESSIVE HEAT WARNINGs AND EXCESSIVE HEAT WATCHes will remain in effect. Please refer to LAXNPWLOX for the latest details on the various heat products as well as the wind advisories.

As for clouds, subsidence, associated with the upper level high, will keep the marine layer squashed. So, little, if any, coastal stratus/fog is anticipated. The upper level flow pattern remains conducive to keeping the monsoon door open. However, models still do not indicate any significant mid-level moisture surge. Therefore, do not anticipate anything worse than some passing mid to high level clouds through Thursday.

LONG TERM (FRI-MON). 14/154 PM.

For the extended, the pattern looks rather benign. The main feature of note will continue to be the upper level high over the 4 Corners area. Through the extended period, the high pressure will gradually weaken and shift westward over the forecast district. At the surface, varying amounts of onshore flow will continue.

For the forecast, Friday looks to be the warmest day in the extended with a continued potential for excessive heat conditions across the valleys/mountains/deserts while a returning marine layer keeps the coastal areas cooler. For Saturday through Monday, a cooling trend for all areas is expected as the upper level high continues to weaken and the marine layer stratus becomes more extensive. Overall, just typical mid-June weather.

AVIATION. 14/1820Z.

At 1759Z at KLAX, the marine layer was about 200 feet deep. The top of the inversion was at 1900 feet with a temperature of 26 deg C.

Expect skies to be mostly clear tonight across the region. Gusty north winds will affect southern SBA County late this afternoon through tonight with some LLWS, turbulence and mdt to stg UDDF.

KLAX . Moderate to high confidence in the 18Z TAF. There is a 10-20% chance of IFR cigs between 11Z and 16Z Tue.

KBUR . High confidence in the 18Z TAF with VFR conds thru the pd.

MARINE. 14/1200 PM.

Across the southern two outer waters zones, (PZZ673/676), fairly high confidence that Small Craft Advisory (SCA) level winds will increase to Gale Force this afternoon then persist thru late Tue night. Then, SCA conds will continue thru Thu, with a 40% chance of SCA conds Fri. In the northern outer water zone (PZZ670), winds are now expected to increase to GALE WARNING levels this evening according to the most recent data, then persist thru Tue night. SCA level winds are expected Wed night. There is a 40% chance of SCA conds Thu thru Fri.

Across the inner waters north of Pt. Sal, SCA level winds are likely this afternoon through late tonight, then during the afternoon and evening hours Tue and Wed. However, seas may remain at or above SCA levels during much of that time.

In the SBA Channel, SCA level winds and seas are likely across much of the Channel late this afternoon thru tonight. There is a 30% chance of Gale Force winds across far western portions this evening, but expect those to be localized. SCA conds are likely across western portions of the SBA Channel Tue afternoon and evening. SCA conds are not expected Tue night thru Fri.

Across the southern inner waters, widespread SCA conds are not expected thru Fri. However, there will be some marginal SCA level winds late this afternoon through late tonight across northern and western portions, especially near Anacapa Island toward Avalon, and a SCA will ultimately be needed.

Patchy dense fog with visibility of one nautical mile or less will affect the waters this morning, especially across the northern and outer waters.

Very hot temperatures are expected next week, especially inland, peaking Tuesday for the coast and Wednesday and Thursday inland, with heat- related illness concerns.
