SYNOPSIS

09/252 PM.

Cool conditions will continue through Tuesday. Another warm up expected to start on Wednesday, likely lasting well into next week.

LONG TERM (FRI-MON)

09/249 PM.

The offshore flow weakens some on Friday - enough to lower the morning offshore winds some, but not enough to affect temps, which will end up very close to Thursday's very warm values.

Over the weekend the ridge will break down while the offshore flow from the north will weaken and the onshore push to the east will increase. Look for a couple of degrees of cooling each day with max temps remaining well above normal with moderate heat impacts potentially continuing through the weekend and even well into next week away from the coast. In fact another more significant round of heat is possible by the middle part of next week.

No rain on the horizon through at least 10 days.

AVIATION

09/1747Z.

At 1710Z, the marine layer depth was around 2800 feet deep at KLAX. The top of the marine inversion was near 4900 feet with a temperature around 10 degrees Celsius.

High to moderate confidence in VFR TAFs through this afternoon. Low confidence in min flight cats and timing of marine layer return. There is a 30% chance for VLIFR to LIFR conds at KPRB, KSBP, and KSMX once cigs arrive tonight. Otherwise, min flight cats may be off at one at any site. Arrival of cigs may be off +/- 4 hours.

Moderate confidence in winds, although there is a chance winds are 5-10 kt stronger at times as winds will rapidly shift to onshore later today.

KLAX...High confidence in VFR TAF through at least 00Z. Then high confidence in cigs returning tonight, but low confidence when (+/- 4 hours from TAF). There is a 50% chance for IFR conds when cigs are present. Any east wind component is expected to remain below 6-8 kt.

KBUR...High confidence in VFR TAF through at least 06Z. 30% chance for no cigs tonight. Timing of arrival may be off +/- 4 hours, and 40% chance for LIFR conds, 10% chance for VLIFR.

MARINE

09/1247 PM.

Inside the southern California bight, southeast to east winds will continue to diminish through tonight. Then, winds and seas should remain below SCA level through the period, except for a moderate (30-40 percent) chance of SCA level west to northwest winds developing across the Santa Monica Bay and into the San Pedro Channel on Wednesday afternoon and evening.

For the waters southwest through northwest of the Channel Islands and the nearshore waters along the Central Coast, marginal SCA level winds will occur beyond 30 NM offshore of the Central Coast to around Point Conception and south to San Nicolas Island through early Thursday morning. More widespread SCA conditions will develop from each afternoon and evening with a moderate to high (30-50 percent) chance of affecting the nearshore waters along the Central Coast, highest Tuesday afternoon and evening.
