Downtown Sulphur, OK

I'm fairly certain that the ongoing circulation moving out of Delaware County, OK into northwest AR and southwest MO is the same mesocyclone that produced the violent Sulphur/Holdenville OK activity during the evening. That's the remnant mesocyclone embedded within the QLCS.

Waiting for it to peacefully pass.

Line segment approaching you appears to be outflow dominant. Hopefully the winds aren't too high there when it arrives.

Just a devastating scene. For comparison, here's how it looked before.

I am not sure of it but that looks like at least EF3 tornado damage.

 

[buckeye05]

I AM NOT SURE OF IT BUT THAT LOOKS LIKE IT IS AT LEAST EF3 TORNADO DAMAGE.

Dude turn your caps off, please

Sorry!!! I have a bad habit of that. It is not against anyone at all.

But yes I’d say a strong EF3 candidate. Whole building is flattened. Grocery stores and large retail stores have no interior walls though, so likely not an EF4 candidate.

I was thinking a 150 mph EF3. Since surveyors are sometimes really conservative about on how well-built something is.

I've yet to see any confirmed reports of fatalities from either outbreak in this sequence so far. Assuming that holds true, if that's not a testament to the overall warning process and the public response to it given the ferocity of what has happened, then I don't know what is. Even with today's technology, Friday alone easily could've been a day with dozens of fatalities, not to mention the after dark significant tornadoes striking towns in southern Oklahoma on Saturday evening...

I am sorry to bother you with this but a large isolated retail building that is completely destroyed has an expected value of 173 mph which is EF4. However, do you see any kind of contextual damage around the building to support that rating? The Taco Bell in Winchester, Indiana according to the EF-SCALE had a expected value of 171 mph which is also EF4 but I am going to assume the lack of context surrounding the building supported a high-end EF3 rating.

In terms of last night’s event, most of the damage reports seem to be coming out of Sulphur and Marietta. Not hearing much from Ardmore or Dickson, but I’d be surprised if there isn’t at least moderate damage in both of those areas. I suspect there will likely be major damage found in rural areas near Holdenville too.

I found closer photos of the grocery store. I was wrong; large parts of it are still standing. We can rule out EF4, and probably high-end EF3 too. Nothing crazy context wise either, but some semis were thrown around and stacked on top of each other nearby.



And again, the Taco Bell having no interior walls was a bigger reason for EF3 in Winchester than contextual issues.

I saw one Twitter report of a chaser in Dickson saying that a few homes had been flattened and that search and rescue was ongoing in the area. Other than that, I've yet to see much come out of there.

Yikes. If houses are flattened there it’s definitely worse than moderate damage. Probably won’t know the true severity until daylight, but that sounds bad.

I’m really surprised at the lack of reports from Ardmore. Based on Google maps, it went through an industrial area with large factory buildings and warehouses.

Nevermind what I said. I see what you are talking about.

Some of the worst damage to the downtown part of a town I have seen in a bit. Worse than Perryton I'd say.
