#POSTFIRE [UPDATE 9/4/24 at 8:50 p.m.] The fire is now 130 acres and is 20% contained.

High temperatures today and tomorrow (Friday) look quite similar, e.g. HOT, with only minor differences, if any (up to 1-2 degrees warmer Fri than today for most areas except the desert, which will be up to 1-3 degrees cooler). #CAwx

CAL FIRE/San Diego County Fire is monitoring a fire well within Mexico. The fire is approximately four miles south of the international border and does not currently pose a threat to the United States. We use cameras from ALERTCalifornia to locate fires, like this one, from their mountaintop

We knew high temperature records would be tough to beat today (thanks 2020) and they were. So far the only record is at Indio with a high of 121, breaking the old record of 120 set in...you guessed it...2020.

BAD🔴: Another scorcher on Friday🥵 Less bad🟡: Less hot, but still quite hot this weekend - a few storms possible for the inland valleys/mountains😐 Much better🟢: Cooling trend next week brings temperatures back to near-average😎 #cawx #socal

Did you catch the sunrise today? Here's a time-lapse taken by one our mets, showing 2 cool features that occurred the atmosphere this morning - the 1st is a layer of altocumulus clouds and the other was a sun dog(!), visible as the bright spot to the left of the actual sun. #CAwx

A sundog (also called a mock sun or parhelion) is an atmospheric optical phenomenon that appears as a bright spot (or smaller sun) to either one or both sides of the actual sun, sometimes accompanied by a halo around the sun.

These are caused by sunlight refracting off of ice crystals in the atmosphere. This morning's sounding shows our freezing level at ~15k ft, while the layer of altocumulus were ~16-17k ft - which means they were likely partially made of ice crystals and not just water droplets.

These are more common in colder climates where glaciated (frozen) clouds form more easily, and are a much more uncommon sight down here in SoCal - so we found this super cool. If anyone has other pictures of this phenomena from this morning, we'd love to see!

Finally, do these clouds mean storms? Not today, conditions are too dry & stable through the rest of the atmosphere. They are a indicator of moisture aloft, which will incr & help lead to our thunderstorm chances Sat/Sun, when a lot of inland areas have >= 15% chance of Tstorms.
