From Meteorologist Chad Crilley on FB: (10/5/26) Monday FULL Forecast - Scorching Temperatures Continue, Relief is Finally in Sight

San Diego County is in the grips of a major heat wave that has brought record-breaking temperatures over the last several days. The relentless heat brought on by an area of high pressure bringing dry offshore winds to the area continues today, with high temperatures in the mid-90s at the beaches and triple digits inland.

An Extreme Heat Warning continues for San Diego County through Thursday, with little relief expected between now and then. Meantime, an Extreme Heat Watch has been issued for #ImperialCounty Wednesday morning through Thursday afternoon. As high pressure expands before weakening, temperatures there may reach 105-107 degrees.

Meantime, dense fog is expected during the last day of our heat wave Thursday at the beaches during the morning. If you have lived in Southern California for a while, you know Santa Ana heat waves often end with very dense fog. This is because as the marine layer returns, it often starts off very shallow and close to the surface.

A Coastal Flood Advisory begins Wednesday as large swells return to our beaches. Minor coastal flooding and coastal erosion are possible.

By the weekend, a large area of low pressure will dig in from the north. This will finally put an abrupt end to the heat. There is a slim chance of showers Sunday and Monday, but the better chance of rain looks to stay across Arizona. Interestingly, this system looks cold enough to produce a few flurries across the San Bernardino County mountains; however, no snow accumulation is expected. #Socalwx #Imperialcountywx #Oceanside #Carlsbad #Sandiego #Brawley #Elcentro

LA Times: SoCal heat wave shatters multiple records, and the misery is far from over

"...A persistent heat wave has shattered October records across Southern California, with downtown Los Angeles nearing an unprecedented streak of 100-degree days and temperatures running as much as 22 degrees above normal...."

.SYNOPSIS...05/230 AM.

A major and long lasting heat wave will to persist through at
least Thursday with dangerously high temperatures. Friday into
Sunday, temperatures will trend cooler each day and there is a
small chance of showers and thunderstorms due to moisture from
distant Hurricane Rachel.

.SHORT TERM (TDY-WED)...05/905 AM.

***UPDATE***

The heat wave continues. However, there is a small ray of hope
that at least the beaches and up to a few miles inland may be as
much as 5-10 degrees cooler today as offshore gradients have
weakened by almost a millibar. ..."

Seriously hoping there is a typo there.

Afternoon high temperatures were several degrees above the daily normals under clear skies with gusty winds. Look for nearly identical conditions returning Monday. #azwx #cawx https://t.co/Vo6tfVl9h0

101.3F outdoors; 107F in the attic with solar attic fan running (!), which is interesting. (ie it's helping to keep things very close to ambient... I imagine it would be much warmer without the fan). #atticfan #heatwave #CAwx

Gah

#heatwave #CAwx

11am and already 100F on day 3 of #CAwx #heatwave

96.8F (36.0C) at 10:42am. Only 25% humidity, at least, so cooling via sweating is very effective. Stay hydrated! #heatwave #CAwx #VenturaCounty

73F to 87.7F in less than 30 min... I guess we're back into it. (yeah, graph is UTC not PST, lol) #heatwave #CAwx

Let's see what the weather model soundings say -- aha! The red line at the bottom is temperature, says 79F at the surface at this location around here... then you see th temperature RISES as it goes up in elevation, and then falls again. So it's showing in the model charts. (will have to look for a balloon if there are any up... weather balloons are scarce nowadays since the DOGE cuts, except weather balloons are still going up here as they are critical for SpaceX launches 🤨 )

Where the green light meets or approaches the red line is where clouds form, btw.

#CAwx #heatwave

Hmm, what is with all the higher altitude heat already this morning?!

Mountain tops up at 80F+ (81, 83, 85, etc.), valleys in the 70's. Sun is just rising now.

Highs are forecast
to be 15 to 27 degrees above normal for our valleys, coastal
mountains, and coastal areas, with the most unseasonably hot
conditions focused over the LA Basin, and the LA and Ventura

Temperatures will remain above normal through the upcoming workweek with lower desert highs reaching near 100 degrees in Phoenix to solidly in a 100-105 degree range in Yuma and El Centro. Another couple windy days are upcoming with gusts reaching 20-35 mph. #azwx #cawx https://t.co/E9BYQUU89B

It's 59f outside and 71f inside our house in #Monterey #California. At least it's cooled down some. But the house is really holding onto the warmth of yesterday.

Under sunny skies and breezy conditions, high temperatures this afternoon were near to slightly above the daily normals. Very similar weather setup tomorrow with temperatures a couple degrees warmer and wind gusts somewhat stronger across south-central Arizona. #azwx #cawx https://t.co/jXMInsyHci

Yeesh, much warmer than was forecast down there in Camarillo. 90F, was 94F earlier. #heatwave #Camarillo #CAwx

Continued hot conditions on Monday.

#CAwx #SGX #graphicast
As can occur this time of year, the coast is seeing its hottest temperatures of the year (and in some places, daily record highs) here in early October, courtesy of offshore winds.

Morning easterly winds will become progressively weaker Sunday through Tuesday, lessening the potential each day for temperatures to spike into the upper 90s at the coast in the mornings before the sea breeze knocks them down in the af

#ChadCrilley #CAwx #SanDiegoCounty #HeatWave

From Meteorologist Chad Crilley on FB: 1:00 PM: Oh my! Temperatures are going nuts at the coast. In true Santa Ana form, temperatures are the hottest at the beach with widespread triple digits. I expect most beach locations to reach 105-107 degrees before the day is done. The record for this date downtown 104 set in 1987.

@ai6yr @uccawx @cookiesinheaven

Low temperatures this morning ranged from the upper-60s to lower-80s. Areas with breezy morning winds experienced the warmest temperatures. Yuma set a new daily warm low record and was 1 degree shy of tying the monthly warm low record. #azwx #cawx https://t.co/mJ743xdPQr

Happy Saturday! Here's a 5-day outlook for the region. Breezy to locally windy conditions will continue through the beginning of next week. Temperatures will also remain above normal through at least the middle of next week. #azwx #cawx https://t.co/9ZRJOU4RdI

Interesting (but bad)... these are conditions that will bring on "classic" (non-exertional) heat stroke. ie nearly two weeks of heatwave conditions with poor overnight cooling. #heatstroke #heatwave #CAwx
