NEW:
The Storm Prediction Center, on or about November 16, 2026 will begin issuing afternoon Day 4-8 Severe Weather Outlooks, at 2130 UTC (4:30 PM CDT/3:30 PM CST).
The content and format of the outlooks will not change; only the addition of afternoon issuances.

It appears that @ChasingWConnor may have captured a view of the potentially significant Overgaard, Arizona tornado around 7:06 PM MST while it was still ongoing. The tornado would have been north of town at this point, and it was a big one!

A significant tornado outbreak is becoming possible on the eastern side of future Isaias. Exact location TBD. EF2+ tornadoes on the table. This is not your typical tropical system. These hybrid transitioning hurricanes near landfall have historically produced significant tornado outbreaks (Ex.Milton). Could be a rather prolonged event with tornadoes possible the day after landfall as well as Isaias phases with sub tropical jet.

On this day in 2013, a low-end EF4 tornado impacted areas near Pierson, Iowa, severely damaging or destroying several homes.
Personally, I find the EF4 rating somewhat questionable and believe this tornado may not receive an EF4 rating under today’s standards. The 170 mph rating was primarily based on a home with most exterior walls collapsed while small interior rooms remained standing, a vehicle reportedly lofted approximately 30 feet, and a grain wagon that was moved roughly 400 yards and produced scour marks in the asphalt.
The structural damage to the home and the vehicle behavior appear more consistent with high-end EF3 intensity, likely around 150-160 mph. The grain wagon also appears to have played a significant role in supporting the EF4 rating, but there does not seem to be enough evidence to establish that EF4 winds were necessary to move it that distance.
This analysis is not intended as criticism of the National Weather Service or its survey process. Rather, it represents my personal assessment of the available evidence and reflects my interest in detailed tornado damage analysis.

Just an absolute beauty. Structure and perfect tornado. (Old transparency film converted to digital format. A bit of loss in the details!). Brown County, SD F3 tornado, 6/23/2002. #sdwx

Back in the good ole days.....Nikon F5 film camera with a fisheye lens, Fuji Provia 100f film. June 23, 2002 Brown county, South Dakota cyclic absolute beast! Produced an F4, F3, and several other weaker tornadoes. Could count the number of chasers on this on one hand (Including Gene Rhoden and Bill Gargan)! Left Denver, CO at 4am first day of the tour and made it close to Aberdeen, SD as the storm exploded on the triple point. Photo degraded a bit before I was able to have it made into a TIFF file. #sdwx #sdtornadoes #F4Tornado

Updates from the field: Our 2nd #Minnesota radar and 33rd in our fleet was raised last week in the City of Brainerd, Minnesota in Crow Wing County. We plan to add up to eight in Minnesota in the near future. Our team was on-location again with members from the community and local, state and federal partners.

A direct quote from the NCDC storm data narrative:
"It is very highly likely that this tornado produced winds that would be classified as an EF5 tornado in the vicinity of Southgate Road." 🫠
The April 2026 Storm Data publication includes the entry for the April 23 Enid, Oklahoma EF4 tornado. The narrative states that the tornado likely produced EF5-intensity winds near Southgate Road based on multiple independent engineering analyses.
In summary, researchers from the National Severe Storms Laboratory and the University of Illinois used several methods, including treefall pattern analysis, Monte Carlo simulations, and 3D vortex modeling, to estimate the tornado's wind speeds. Across these independent analyses, estimated peak 3-second wind speeds consistently fell within the 204-217 mph range, with the report concluding it is very highly likely the tornado produced EF5-intensity winds in the Southgate Road area.
Given all of this research, I'm left wondering: why wasn't the tornado upgraded to EF5? If multiple independent analyses support EF5-intensity winds, and there are damage indicators that could potentially justify that rating, what prevented the upgrade? I'm not frustrated, I genuinely want to understand the reasoning. If any NWS meteorologists or NOAA personnel can provide insight, I'd greatly appreciate it.

Need a role count of all the out of state chasers who will be chasing tomorrow! Trying to get a chaser meetup somewhere before the chase!

Yeah, you'll generally be able to determine that through the thermodynamics and wind profiles before the event starts. We want to create our own in-game weather "model" of sorts (think GFS, NAM, RAP, etc) with soundings, and also have observed soundings you can look at.
