Just want to jump back in here and thank
@Jon Davies for taking time to post a detailed response and elaborate on the subject. Actually taking time and walking parts of the damage areas to do his analysis certainly reflects his level of commitment.
I am curious as to the “merger/handoff” and look forward to any additional info or updated analysis. Please keep us updated Jon!
Spending about another 6-8 hours reviewing KTWX data (both reflectivity & velocity) as well as watching videos, it appears there is a little insight regarding the second mesocyclone formation. The data does not suggest or reflect that the second mesocyclone formed well behind the surging tornadic RFD, but rather in a very fluid, dynamic, and ever evolving area ahead of or right along (more likely) of it. From here it is very ambiguous - meaning it seems a little unclear as to the exacts of the original mesocyclone that was cloaked in rain and ultimately being pulled in to the secondary mesocyclone as explained in great detail by Jon. As such, I can now honestly say that as a 29 year veteran and from a meteorological standpoint - I very well may have been in a bad situation had I been on this event. Hell, I don’t even know what to call this exactly...a merger? A handoff? This is the question for the possible similarities and correlation between Hesston/Gossell event in 90’
As such, there are a few things of interest I noted and wanted to make mention of and or question:
1) Looking at the road network from near Lone Star Lake and the “east option” - it appears the east option turned into a road nightmare ultimately ending up in gravel roads with only a north/south options. For those that took this east option, what was the experience like? In other words, was it truly a safe and viable option in your opinions?
I believe
@Quincy Vagell you went east correct? I’m trying to get a bearing on the exacts of this option because it would appear that the entire northern convergence and associated mesocyclone with a non tornadic RFD (at that point) and ultimate LARGE TORNADO engulfed the area just to the east. I mention this because I do not know if going east would have been an option that I would have personally chosen — given the fact that you would be placing yourself into an even worse position? The east option would have left me little to no room for error due to the road network. I would have not chosen this option.
2) The “north option” was obviously a bad call as one would basically be driving into a convergence area and newly formed mesocyclone right overhead as it moved east northeast. Thus, this would lead me to question that option had I been there in the exact spot as Roger/SLT. I would have avoided this option as well.
3) Obviously no west option existed.
4) Thinking totally analytical here... the south option has the least possible “associated threats” *from experience* understanding that I am referring to *at the exact time SLT decided to move south*. In short, I don’t know that I would have done anything different *if* put in the same position. Which actually scares the hell out of me. Obviously I am playing Monday morning quarterback here.
If we didn’t know, we obviously learned that you do not place yourself in the path of the oncoming HP on 5-31-2013. But this is an entirely different situation. As mentioned, very fluid, dynamic and ever changing. Given all relevant facts (data, position, topography, road network) the tornado was “small”, buried within the RFD surge and while an area of concern and should be given extreme caution, not likely an area that I myself would not have driven into to escape or reposition. Guests or no guests.
What I am saying publicly is that as another tour owner, a veteran of the game and meteorologically speaking, I would have likely made the same decisions *If* I had been in Rogers position and that I understand his thought process now. After spending almost 40 hours reviewing the data, and above listed topics, I think I understand his position totally (situational speaking).
I would also go so far to say that I even understand why he thought it was a satellite tornado *at the time*. Let me explain:
Given the distance (or lack of) between the mesocyclone’s times and locations as
@Skip Talbot highlighted - it might be perceived that this was 1 mesocyclone/cyclical HP supercell. You decide to escape or even just reposition and less than a mile down the road to the south (less than 60-120 seconds @50-60mph later) you’ve got a tornado buried deep in the RFD surge that is coming right at you. We all knew pretty quick that it wasn’t a satellite tornado BUT ONLY *after the fact* or after those who were there were kind enough to share their video. How many times have we ALL done this or experienced this? Even other tour companies just as I mentioned in my original post. That’s a rhetorical question FYI.
Some have suggested and have questioned my stance and recently questioned my previous analogy as anecdotal and hinted at “character questioning”. This is absurd to me. Simply stated one more time for clarity sake, I have no hidden agenda here. Let’s look at this logically....If this situation causes the Hills/SLT go “belly up” would it not be beneficial for me as a business owner in the same line of established hard work? Of course it would. But that’s not my position. As far as my analogy, I was merely using a past event to highlight that we have ALL been in a position that may not be clearly defined or understood as dangerous. Nothing more, nothing less. Therefore I’m not going to reply to the last question/post directed at me as it would likely land me in ST “jail”. As I said in my original post, I’m just thankful everyone walked away. It certainly could have been much worse.
I anxiously await
@Skip Talbot s analysis with the hopes that it might shed additional light on the subject.
