Alex, Noah and Everyone,
Please allow me to answer your comments.
Again, congratulations to STL NWS, Alex, on a great job Sunday night. Really well done.
The situation in which we find ourselves is nothing like the Apollo program. By 1967, Apollo hadn't even begun. The space program was on a tremendous upward trajectory (the tragedy of Apollo 1 notwithstanding) with Mercury and Gemini. It certainly was not deteriorating. In 1944, after only two years of work, the Manhattan Project had atomic bombs that worked.
The NWS tornado warning program peaked in accuracy in 2005-2010
and has been deteriorating since including the horrific tragedy of the Joplin Tornado. JLN was caused by the terrible NWS warning quality that day, the misapplication of tornado sirens by local emergency management, and the fact the tornado was rain-wrapped and invisible to those along its path. The combination lead to the loss of 161 lives. See:

I am hardly the only person who has noticed the tornado warning issues. Here's a 2007 article from the
Washington Post.
https://www.washingtonpost.com/news...es-as-researchers-struggle-to-understand-why/ KWTV in OKC six months ago was running a promo that said, "We don't wait for the National Weather Service."
Alex wrote,
the CIMSS ProbSevere tool has the product "ProbTor", an AI/ML-based tool used to diagnose the tornado potential of a storm. While it is not used solely to determine if a warning should be issued or not, it serves as a confidence builder/reducer. Radar still reigns supreme, though. While I don't know how long ProbTor has been in the field, it does not seem to be working, based on the NWS's own statistics. How long a period was ProbTor independently tested in a real-time warning environment before it was put in the field?
The NWS certainly is not the only source of tornado warnings. WeatherData/AccuWeather issues its own tornado warnings for its clientele. In view of issues with the NWS warnings,
more and more television stations are issuing their own warnings. You might have seen the VP of DTN on LinkedIn last week bragging about their tornado warnings and I know of five other commercial companies that are now doing the same. I do
not view this as a positive development. But, as long as NWS tornado warnings continue to deteriorate, the private sector will step in to fill the gap. Saying we should continue to spend money on DOW observations is like saying we should improve the quality of the popcorn while the movie theatre is on fire.
It isn't like we started doing with DOWs 2 or 5 years ago.
We have been chasing tornadoes with DOWs every year for more than a quarter century! See:
A Mobile Mesonet for Finescale Meteorological Observations
We have done six VORTEX's plus other field programs about and related related to tornadoes (PECAN, etc.). Most of that data is still sitting on the shelf (I directly asked one of the PA's). I participated in the NSSL forecast testbed the summer of 2016 where we evaluated a number of satellite/statistics and other datasets. DOWs were never mentioned in the classroom discussions when the instructors explained how the statistics and techniques were evaluating were derived.
From 1967 to 1971 NSSL ran a super-mesonetwork (stations as close as every five miles) in central Oklahoma in a square from around OKC to Chickasha. Not only did they have 100+ surface stations, they launched rawinsondes at 3-hour intervals when storms were expected and at 1-hr intervals once storms had fired. They did that OKC, LTS, END, CHK, FSI and CSM
. That huge data set produced just a single paper -- on trends in the lifted index. That's it. A huge investment in resources practically wasted. That data would be incredibly valuable today to use for mesoscale modeling experiments. Unfortunately, all of it burned in a fire at an NSSL storage unit about 15 years ago. This demonstrates that presuming the data will be used at some point in the future may not turn out to be the case.
As to using the DOW data to train AI, etc., what is wrong with that dataset as it currently exists? How many of the DOW in-situ observations have actually been used? Why do the taxpayers have to continue to fund more?
Noah, you ask the good question, "Why not fund both?" And, that may seem reasonable when the Administration throws around money by the trillions. But, as a taxpayer, I want the meteorological community to be good stewards of tax dollars. If someone (Bill Gates, Jeff Bezos) wanted to fund DOWs and future VORTEX-type experiments I would be 100% for it and would write him or her a thank you letter. But, given how little we've gained, I would say that
we need to wring every bit of data we can from existing datasets before we ask for more, especially when our nation is trillions of dollars in debt.
Want to improve tornado warnings? Fund gap-filler radars. Train meteorologists in simulators in a step-by-step process the way may generation was trained (I believe a lot of the issue with NWS TORs is the experience that has walked out the door as my generation of mets has retired). That is the way to address the immediate problem, not DOWs or VORTEX and hoping that data eventually proves useful.
About 40 years ago, medicine learned if it was going to advance, it was going to have to stop sweeping mistakes under the rug. Most all hospitals now have weekly mortality and morbidity (M&M) meetings where everyone candidly discusses their mistakes. Meteorology simply refuses to do this. Heck, the NWS doesn't even do its weak "service assessments" any more when the quality of its performance is in doubt!
That is why I a strongly advocate an independent National Disaster Review Board (NDRB), modeled after the National Transportation Safety Board, that would take a hard look at these issues from all sides and advise NWS and private sector entities how to improve. An excellent candidate for this type of investigation would be the recent flash flood in Tennessee that killed 18:
The Catastrophic Tennessee Flash Flood - Why The United States Needs a National Disaster Review Board and, the multiple unwarned tornadoes of this past summer (two examples here:
Bensalem Tornado: Another Dangerous National Weather Service Warning Miss - and - here:
Friday: Another Dangerous Missed Tornado Warning ).
It is entirely possible an independent NDRB might say I am wrong about all of this and that's fine. But, right now, we have entities -- at best -- examining themselves without a fresh perspective. The NTSB is one of the most successful things the federal government has ever done. Let's replicate that success!
Finally, none of what I have written is personal. Terms like "narrow-minded," etc., don't get us anywhere. If meteorology is ever going to mature as a science, we need to stop with the name calling and be open-minded to the wide perspective of views from throughout our field.
Thank you for your kind attention and your consideration of my perspectives.
Mike
