SYNOPSIS

14/346 AM.

Seasonal June conditions will continue through the week as at least weak to moderate onshore flow continues, with night through morning low clouds and fog across most coastal areas. Near to slightly above normal temperatures will continue through early next week, with minor afternoon heat impacts, before cooling down during the middle of the week.

LONG TERM (WED-SAT)

14/521 AM.

A slow-developing trough will likely build into region Wednesday or Thursday and bring moderate cooling trends away from the coast, drastically reducing heat risk even to warmer interior areas. Night to morning low clouds will likely continue, but expand well into the coastal valleys and possibly some lower foothills.

The associated onshore push will support gusty onshore to northwest winds nearing advisory levels for the interior, possibly extending to southwest Santa Barbara. There may be a period of enhanced fire weather concern on one or both of those transition days (Wed/Thu) for far interior areas and maybe especially at high elevations, which would be situated above the expanding marine layer influence.

Looking further out, there's a 50-60 percent chance of above normal temperatures returning and perhaps becoming more widespread during the early to middle part of next week as a ridge potentially builds into the region.

AVIATION

14/1803Z.

At 1708Z at KLAX, the marine layer was 1000 ft deep. The top of the inversion was near 3000 ft with a temperature of 23 C.

High confidence in VFR TAFs for desert airfields (KPMD & KWJF).

Low to moderate confidence in remaining TAFs. Timing of CIG/VSBY restrictions may be off 3 hours and flight minimums by one category.

KLAX...Low confidence in TAF. Intermittent CIGs around 008 are possible from 14/18Z-14/23Z as stratus hangs along coastline. Thereafter, IFR CIGs 005-007 should arrive 15/05Z (+/- 2 hours). Stratus could hang along coastline again 15/18Z - end of fcst pd. No significant east wind component expected.

KBUR... Moderate confidence in TAF. High confidence in VFR conditions through 15/08Z. 30% chance of LIFR CIGs 12Z-16Z.

MARINE

13/821 PM.

Moderate to high confidence in current forecast. Conditions are generally expected to remain below Small Craft Advisory (SCA) levels across the coastal waters through the forecast period.

Local gusts could reach 21 kts during the afternoon and evening timeframe across the western Santa Barbara Channel, Santa Monica Basin, and nearshore Los Angeles Harbor into the San Pedro Channel.

Patchy dense fog with visibility 1 NM or less is possible each night to morning through at least Monday.

LOX WATCHES/WARNINGS/ADVISORIES

CA...Beach Hazards Statement in effect through Monday evening for zones 349-350-354-362-366. (See LAXCFWLOX). PZ...NONE.
