SYNOPSIS
02/332 AM.

Temperatures cooler than normal will linger today due to strong onshore flow and a persistent marine layer. A warming trend will establish through Thursday due to high pressure aloft building in and weakening onshore flow. The warming trend will be most pronounced away the coast into the interior valleys. Closer to the coast, night through morning low clouds and fog with persist with moderate to strong onshore flow continuing. Clouds may continue to struggle to clear from the beaches.

.SHORT TERM (TDY-TUE)...02/438 AM.

The latest satellite imagery indicates low clouds and fog pushing well into the coastal slopes of the mountains early this morning as strong onshore flow and a persistent deep marine layer depth remain in place. An eddy circulation continues to spin just northwest of Santa Catalina Island, deepening the marine layer depth to between 3000 and 3500 feet deep south of Point Conception. To the north, the marine layer depth is closer to around 2000 feet deep this morning as clouds are pushing into the interior valleys of San Luis Obispo County. Patchy drizzle is possible this morning and there is a good chance that an update will issued to the forecast as some rain gages are starting to pickup drizzle and ceilings at area airports are falling slightly. A cooler weather pattern will linger today across much of the coastal and valley areas, and these areas are likely below to slightly below normal. Across the interior, temperatures will start to warm as downsloping effects continue and onshore flow starts to wane.

Gusty Sundowner winds are weakening across southern Santa Barbara County this morning, but the northerly surface pressure gradient will tighten over the coming days, potentially bringing another couple rounds of Sundowner winds. With the gradient progged to be slightly weaker today, wind advisory headlines were tabled for this afternoon and tonight, but the gradient will tighten on Monday night and could bring another round of advisory level Sundowner winds. Gusty northerly winds will also develop through the Interstate 5 Corridor and a wind advisory will likely be needed for this area, as well. Marginally gusty winds could possibly also extend into portions of the far western Antelope Valley.

A warming trend will take shape over the coming days as 500 mb heights climb. The developing northerly surface pressure gradient and climbing heights will weaken the onshore push each day and thin the marine layer depth some. The warming trend will become more pronounced between Tuesday and Wednesday across the interior portions as hot temperatures will develop across interior valleys and adjacent foothills, but closer to the coast, a persistent moderate to strong onshore push will remain and keep the warming trend more moderate along the coast. The likely scenario will be for a June Gloom pattern to keep low clouds and fog hugging the beaches each afternoon, then the clouds will push back in during the evening.

.LONG TERM (WED-SAT)...02/437 AM.

Temperatures will warm closer to critical levels for excessive heat across the Antelope and San Luis Obispo Interior Valleys on Wednesday. NBM solutions are suggesting a greater than 95 percent chance of 100 degree high temperatures for KPMD and KWJF on Wednesday, and high chance of temperatures reaching 105 degrees.
Chances for very hot temperatures are lower elsewhere but still near excessive criteria across the Carrizo Plain. Given it will be a close call, an excessive watch was added for Wednesday afternoon and evening for Antelope and San Luis Obispo Interior Valleys and adjacent foothill areas to highlight the potential for excessive heat. As it is a marginal case, it would not be surprising to see the watch either dropped or converted to an advisory or warning. With the southeast flow aloft developing with the ridge building into southeast California, it is possible that this watch could also be extended into Thursday.

There is good amount of uncertainty for Thursday and Friday as EPS and GEFS solutions offer up quite a bit of spread for high temperatures. The chances for 100 degree temperatures fall in NBM solutions into Thursday. There is a low chance that an early start to the Southwest Desert Monsoon could develop across southern California. This could cut into temperatures by increasing cloud cover across these areas. In hinting at the possibility, EPS cloud cover means do increase some between Thursday afternoon and into next weekend.

With the ambient southeast flow aloft, PoPs and chance for thunderstorms are non-zero for Thursday and Friday, but PoPs still remain below mentionable levels during the afternoon and evening. Pattern recognition would suggest the pattern consistent with the monsoon developing but forecast ensemble and deterministic solutions do not have a good handle on it. Stay tuned for updates on this.

A cooling trend should develop for next weekend as troughing digs into the region.

AVIATION
01/2309Z.

At 2215Z at KLAX, the marine layer was 2600 ft deep. The top of the inversion was at 4800 feet with a temperature of 20 deg C.

Overall, moderate to high confidence in 00Z TAF package. High confidence in return of CIG/VSBY restrictions to all coastal and valley sites, but only moderate confidence in timing of flight category changes (could be +/- 2 hours of current forecasts).

KLAX...Moderate confidence in 00Z TAF. There is a 40% chance that IFR conditions will not develop overnight. Moderate confidence in timing of flight category changes (could be +/- 2 hours of current forecasts). No significant easterly wind component is expected.

KBUR...Moderate confidence in 00Z TAF. Timing of flight category changes could be +/- 2 hours of current forecasts.

MARINE
01/836 PM.

In the northern outer waters zone (PZZ670), Gale Force winds will continue tonight. Then, SCA conds are expected (80% chance) late tonight thru Tue. There is a 40% chance gales Sun afternoon/eve.
There is a 50% chance of SCA conds Tue night/Wed morning. Conds should then be below SCA levels Wed afternoon through Thu.

In the southern two outer waters zones, (PZZ673/676), SCA conds will likely continue through at least late Monday night or Tuesday. Conds should then be below SCA levels late Tue night through Thu.

In the inner waters N of Pt. Sal, SCA level winds are likely (70% chance) during the afternoon/eve hours today thru Mon and possible thru Tue. Conds will then be below SCA levels Tue night through Thu.

In the inner waters S of Pt. Sal, there is a 60% chance of SCA winds in western portion of the SBA Channel during the afternoon and evening hours through Mon. Otherwise, conds over the inner waters should be below SCA levels thru Thu.
