Good to hear; Lake Travis has put in good work for us in the past.
Llano river is flooding
Lake Travis is finally filling up
Pedernsles River rolling too
Fill up lake Travis

homeschool learning >>>>>> paper degree from rich oligarchy "university" full of greedy old wealthy tenured "regents"
Depends where you're learning. Ten years ago when it was free Coursera was amazing and I use to take their algorithms courses for fun because there were always great communities around them where we'd compete with each other trying to come up with the most efficient algorithms and implementations and we'd always try to one up each other once someone got to the top of the leaderboard. MIT OpenCourseware is an amazing resource too. Always loved Walter Lewin's three semester introductory physics series, especially how he teaches calculating uncertainties in experiments so you can unambiguously determine whether or not an experimental result is consistent with a theoretical prediction. Amazing stuff that's usually left out of intro physics courses.
At least you're open minded about this subject. Some people are "muh formal education uber alles must pay six figures for a degree or else ur stupid muh uh" .... Dumb rhetoric.
I learned by figuring things out bit by bit and reading all the meteorology stuff as it happened, focused on the fine details from actual Dr.'s of meteorology who would be featured on The Weather Channel in my childhood, reading real articles from NOAA, CIMSS and other excellent meteorology resources, etc. You don't have to go to formal education and pay five or six figures and take formal classes. If you do, that's fine; if you don't, that's also fine.
Pleasant summer day today after the rain. I've had warmer days in Ohio and even Michigan.
If you find someone with a meteorology degree let me at them.
I have lots of questions. Like heat domes. These features defy some of the fundamental ideas I have concerning thermodynamics.
Basically concerns why they dont go away fairly quickly.
Because large high-millibar (typically 1030mb and up) high pressure ridges under which those "heat domes" exist? They always have. And when they settle in place, it often takes time for a low pressure system or systems, from troughs to upper-level lows to tropical cyclones, to erode them and provide relief in the form of cooling and/or precipitation. Essentially in those cases a ridge will move out to the path of least resistance or, weaken and split in two in essence.
In summers like 2011, most of 2022 and essentially all of 2023, the high millibar ridge essentially turned Texas into eastern Arizona. In 2024, this feature is much weak, and has been weakened and maintained weak by systems such as Alberto and Beryl that, even though they're long gone, they've eroded the ridge long enough to where it's much easier this year than in past years for low pressure systems to poke holes in the high and cause rain and below average temperatures during this time of year which is a very unusual type of year for south central Texas to receive any kind of precipitation at all, not to mention the sheer volume of rain we've had lately which is unseasonal for sure.
Congrats.
The world set a record temperature Monday.
All is well in Austin and San Antonio though and that’s the only temp that counts
High pressure heated alr expands rapidly unless surrounded by higher pressure.
It does not take a tropical event to have places where air is less dense.
So why does this persist? This high pressure can’t extend indefinitely.
Settling in to place must mean they are surrounded by even higher pressure.
There must be a place where the pressure is lower. Tropical storms to hurricanes are low pressure systems.
All it takes is merely lower pressure, this lower pressure is not just found in places that have tropical low events.
For example, higher al udes have lower pressure. It should not necessarily take a tropical event to have lower pressures.

Jet streams (TUTTs, subtropical jet, polar jet), west to east moving troughs that pass by roughly once a week, mesoscale convective systems, and of course monsoon troughs and the intertropical convergence zone. All examples of low pressure systems that aren't tropical cyclones. Any of those can serve to be "weather makers" and erode a high pressure ridge.
So the question still stands.
How can the dome even build in the first place if low pressure exists somewhere around it.
I guess I need to know how a heat dome of high pressure even forms in the first place. What is the hypothetical "wall" around it. If you pressurize a bicycle tire the rubber tube of the tire prevents the leakage or evening out of the air with the atmospheric pressure. This buildup of pressure can and often does go away "a flat" because the wall no longer keeps the high from low pressure. This is a physical pressure barrier to hold the differences for a good period of time. The usual culprit that creates pressure differences at the same al ude is differential heating of the earth. But it is relieved through wind (high to low) and evens out. How are these domes maintained? what barrier keeps it in place? I know it eventual goes away like a tire goes flat. For example if you punch a hole in a pressurized tire the difference in pressure between the inside of the bike tire and the outside atmospheric pressure is more quickly equalized. How do heat domes persist? What is the mechanism?
All explanations welcome. Im sure there is something that makes physical sense.

General lack of low pressure weather makers in a system allow a high pressure ridge to build and concentrate and strengthen and endure until the next low-pressure weather maker arrives to erode and/or relocate the ridge.
Play with this to experiment on how it works

It has arrows. Note the "heat dome" in the form of the massive 1029 MB or higher subtropical ridge in the north central subtropical Atlantic basin.
Damn all this meteorology talk got me interested in checking if MIT OpenCourseware had any video courses for Course 12 (Earth, Atmospheric, an Planetary Sciences) but no such luck. Might still read some of the textbook for 12.003 (Atmosphere, Ocean And Climate Dynamics) though.

Can pirate the book on Library Genesis since textbooks are such a ing racket.
Jesus...
I did not take into account the ROTATION of high and low pressure systems in the Northern Hemisphere. (South as well but opposite from the same perspective)
I got hints of it from UNTs visual play. There may be too much to this to bother but...
More reading tonight.
Dang complaining in late July about it getting to 91 when the forecast high was only 88...we're spoiled this year. Last year we were at around 106
As we head towards climatological peak of heat season, no 100s in sight:

Lake Travis up over 6 feet
Nice
That’s my bath water
Canyon Lake up.
Medina up. But it will be sucked dry again by farms.
Need to make Farm land flexible depending on rapid changes year to year but that costs $.
Our whole societal infrastructure was not ready for this kind of change.
Need to situate farmland in wetter areas particularly back east or in the Pacific northwest. Where there's always flooding and abundance of water. They could use less water, not more. Whereas a place like West Texas shouldn't have farming... pretty much ever. Drier climates should be limited to subsistence gardening and ranching.
Recharge zone got a ton, but Edwards aquifer is nowhere near 700 like it was in 2007
Well J17 is at 635. This is nice.
The recharge zone has to get hit in the right places. The recharge dams have conduits to some gigantic cracks that get loaded with water and recharge.
Really need to see certain springs start flowing again. they are a very good indicator.
Only problem is SA is growing so large that we are probably always gonna have to save water.
They really need to start looking into the amount of water used at big public State owned and Private businesses. Most homeowners are well aware of usage and water penalties. imo...
We really need a reservoir but unfortunately that got screwed up by politicians as I read the history of Applewhite. Some of these guys buying land in the proposed places and then trying to sell the public on it.
That was criminal. We needed a backup imo.
Getting more complex. Fluid dynamics. I get too tired after exercise sometimes and gotta put it down.
There is some very counterintuitive stuff that I love and hate at the same time.
Hope so. August 1st through 14th is the absolute peak season where average high temperature is 97. July 31st and before and August 15th and after it dips below 97 on average.
Drought map I look at often shows countries from SA to west-a pocket- show severe drought
