SYNOPSIS

08/831 PM.

Much cooler conditions are expected on Monday as a coastal eddy brings southeast flow to the area along with coastal low clouds and fog. The cooling trend will continue into Tuesday, with another warm and expected to start on Wednesday, lasting through at least Friday and possibly into next week.

LONG TERM (THU-SUN)

08/157 PM.

Max temps will be the main talking point of the three day stretch. Look for 5 to 10 degrees of warming (across the csts/vlys) both Wed and Thu with little change slated for Friday. Thu/Fri's max temps will be in the mid and upper 70s at the beaches, the 80s across the rest of the csts, and 90s for the vlys. These max temps are 15 to 25 degrees over normal.

The ridge will break down on Saturday and offshore flow from the north will weaken while the onshore push to the east will increase. Look for 3 to 6 degrees of cooling with max temps remaining well above normal with moderate heat impacts potentially continuing through the weekend and even into next week away from the coast.

Both AI-EC and AI-GFS are dry through the 23rd of the month.

AVIATION

09/0246Z.

At 0100Z at KLAX, there was no marine layer or an inversion.

High confidence in VFR TAFs through this evening, then a chance for IFR-MVFR flight cats for KSMO, KLAX, and KLGB after 10Z. Low confidence in potential flight cats, especially early, where LIFR conds are possible. Moderate confidence in winds. A Catalina eddy will develop overnight, likely bringing SE winds to southern coastal/valley sites, possibly also including KSMX.

KLAX...High confidence in VFR conditions through this evening. Overnight, there is a 50% chance that cigs do not develop. Moderate confidence in an east wind component reaching 10 kt from 04Z-14Z. There is a 20% chance for brief winds gusting to 15 kt.

KBUR...High confidence in VFR conditions through the period. Moderate confidence in wind forecast as direction may be off by 30 degrees and gusts may be off by +/- 10 kt.

MARINE

08/836 PM.

Santa Ana Winds have transitioned into northwest Small Craft Advisory (SCA) level winds across the waters near and southwest of Point Conception. A moderate Catalina Eddy will develop tonight, brining southeast to east winds of 15-20 knots with gusts to 25 knots to the waters south of Point Conception through tomorrow morning. The winds are expected to increase across the San Pedro Channel after midnight, then spreading north along the LA Coast and into the Santa Barbara Channel during the early morning hours.

Periods of SCA level northwest winds will then dominate the Outer Waters through the remainder of the week, with low chances of SCA level winds reaching the Inner Waters. Seas will also reach near 10 feet across the outer waters late Monday into Wednesday morning.
