Key points

Downtown Los Angeles reached 104 on Monday, above its old record of 101. NWS Los Angeles/Oxnard says six other sites set or tied records on the same day. It was downtown's fourth straight day at 100 or higher, which the office calls the record for October.
The heat is moving into the deserts. On Tuesday morning NWS San Diego issued an Extreme Heat Watch for the Coachella Valley, the San Diego County deserts and the San Gorgonio Pass near Banning, with highs possibly as high as 108 on Thursday. NWS Phoenix added a watch for the Parker, Gila River, Palo Verde and Chuckwalla valleys.
Southern California's Extreme Heat Warnings still run to 8 p.m. PDT Thursday. The Sacramento and San Joaquin Valley Heat Advisories now run to 10 p.m. PDT Friday. Los Angeles/Oxnard expects temperatures to trend cooler each day from Friday into Sunday.

Yesterday: Los Angeles sets records

On Monday, the fourth full day of Southern California's heat warning, the thermometers went past the old marks. In its 2:38 a.m. PDT Tuesday discussion, the Los Angeles/Oxnard office listed seven records from the day. Downtown Los Angeles reached 104, three degrees above its old record of 101. Woodland Hills reached 106, Camarillo 99, and Oxnard 98, which was four degrees above its old mark of 94. Burbank, Long Beach Airport and LAX each tied their records.

The streak matters more than any single number. The office says Monday was downtown's fourth consecutive day at 100 degrees or higher. In its words, "This is the record for October and it looks like that record will be" extended "by 1 maybe two days."

Today, officially: the deserts take their turn

On Sunday this desk reported Extreme Heat Watches for the Imperial Valley and Yuma. Two days later the watches are longer and they cover more ground. NWS San Diego's new watch covers the Coachella Valley, the San Diego County deserts and the San Gorgonio Pass near Banning from Wednesday morning through Friday evening. It says "high temperatures as high as 108 on Thursday possible" and nights in the mid 70s to lower 80s. NWS Phoenix extended its Imperial Valley and Yuma watch from Thursday evening to Friday evening, and it now forecasts 104 to 108 at Yuma. It also added a Thursday-only watch for the Parker and Gila River valleys in Arizona and the Palo Verde and Chuckwalla valleys in California, with 103 to 106. Phoenix's 3:59 a.m. MST discussion says temperatures will warm "to near record levels."

Along the coast the warning stands, with a small change. Los Angeles/Oxnard expects 2 to 4 degrees of cooling on Wednesday for the coast and valleys south of Point Conception as the afternoon sea breeze returns. It expects another 2 to 4 degrees on Thursday, which would bring valley highs to 98 to 102. The office notes those highs would still be 10 to 15 degrees above normal. North of Point Conception it goes the other way: the Central Coast is forecast to warm 3 to 5 degrees on Wednesday, and a new Heat Advisory covers the San Luis Obispo and Santa Barbara central coast beaches on Wednesday and Thursday.

Farther north, the Sacramento and Hanford advisories now run to 10 p.m. PDT Friday instead of Wednesday. The Bay Area and Mendocino and Lake county advisories run to 10 p.m. Thursday.

The offices agree on how this ends. Los Angeles/Oxnard expects a "more pronounced cooling trend" by Saturday as high pressure weakens, with a small chance of showers and thunderstorms from the moisture of Hurricane Rachel. Phoenix expects "a potential cooler and more unsettled weather pattern" Sunday into early next week.
