Damaging Tornadoes Slam Plains

A devastating string of severe thunderstorms and tornadoes tracked through Texas, Oklahoma, Kansas, and Nebraska on Saturday. This severe weather outbreak was remarkable in its duration as supercell thunderstorms began to pop up in western Kansas late Saturday morning, and the dry line that was supposed to represent the end of the severe weather threat was only halfway through Kansas, Oklahoma, and Texas by 1:00 AM Central Time Sunday. The moisture difference on either side of this dry line was remarkable as well, with dew points in the upper 60's to the east, and a very dry 20's to the west.


SPC Storm Reports from Saturday

The SPC storm reports show the track of these storms, with Kansas being the hardest hit. Early in the afternoon, most of the supercell thunderstorms were consistently producing weak tornadoes that skipped across western and central Kansas. As the low-level jet stream kicked in late in the afternoon and into the evening, the thunderstorms strengthened considerably. Probably the most remarkable supercell thunderstorm began in western Oklahoma near Woodward as a stunning multi-vortex tornado. The tornado actually was several tornadoes that danced into southern Kansas and eventually threatened Wichita. The tornado passed just south and east of the city, producing an 84 mph wind gust at the Wichita Airport. It also did extensive damage at the airport. In addition, the Oaklawn area of Wichita was declared a disaster area very soon after the tornado passed. The Sedgwick County commissioner declared the county a disaster area. This wedge tornado eventually moved along the Kansas Turnpike northeast of Wichita before finally dissipating.

The deadliest tornado of the outbreak struck Woodward, OK early Sunday morning, as the main squall line moved through western Oklahoma. This tornado was very large and particularly dangerous since it occurred at night when most residents assumed the threat had ended. There were multiple reports of not hearing the city's siren, so it is entirely possible that the siren was either struck by lightning or hit by the tornado itself. At least five deaths have been confirmed in the Woodward area from this tornado. Probably the scariest video of a tornado I have ever seen was taken of this Woodward tornado as it moved into town. Note you can see the scale of the tornado as between power flashes.

Figure 3. Radar reflectivity image of the tornado that hit the south side of Wichita, Kansas, causing damage at the Wichita airport.

Perhaps the most telling feature of this severe weather outbreak was its repetitive nature. Salina, KS was tornado warned three times by three separate severe thunderstorms. Similarly, areas from Medicine Lodge to Kingman, Kansas were warned for two separate thunderstorms, while Woodward itself was warned very early in the day before a different tornado moved through the city late in the night.

Last night's storms have weakened, but a new round of severe weather is expected Sunday afternoon over portions of Wisconsin, Minnesota, and Iowa. NOAA's Storm Prediction Center has put the region under their second highest level of alert, a "Moderate Risk."

5 deaths – Major strucutral damage in western and northern parts of Woodward. Preliminary survey results revealed at least EF2 damage; rating subject to change.

Sounds like we might have EF5...

VIA Weather Channel on Twitter: NWS Wichita: Prelim. EF4 #tornado near Kanopolis Lake, KS. A farmstead was decimated, trees stripped of bark, roads scoured.

Won't surprise me if this is updated to EF5.

There are some small showers popping up in the Houston metro area but that's about it for now, I'm wondering a little myself what's going on.

Any damage report from Greensburg to Salina tornado? That tornado was clocked at 207 mph over a open field and multiple towns was under tornado emergency, but I never heard of damage or town being wiped out. I didn't hear much from Wichita tornado either, except for city of Wichita itself. What about towns to southwest of Wichita? That tornado was very strong looking on radar.

I'll say Woodward tornado is a EF-3, because the damage is similar from what I saw in Sanford, NC.

I went to bed after Wichita cell finally died. Before I shut the computer off, I saw that there was a tornado warning from that line in OK/Texas... sadly, that tornado, as I learned this morning, killed 5 people.

Supposedly it's going to get cut off and become Sub-tropical or even tropical.

Quoting MAweatherboy1:

Ok... I've never had very high hopes for this one but with all the model consistency it seems to be an increasing possibility.

Bear in mind what models everyone is looking at... MSLP. Mean Surface Level Pressure.

That doesn't show wind vectors, precipitation, or frontal boundaries. All of those are important to whether a system is named.

All the models are saying is that a cyclone of some sort is likely to form. That cyclone could be a baroclinic one (attached to a front, driven by temperature differences), tropical (warm core), or subtropical (not attached to a front, but not fully warm core).

Based on how, where, and when the system is expected to form... my bet is on a baroclinic one.

In theory. But it also would need to be detached from the front to be an STS.

In other words... don't get your hopes up for a named storm.

Possible?, I guess if NHC went straight to declaring a depression or STS without initiating an invest, yes. Normally they will declare an invest to gather data before taking that step.

Quoting ScottLincoln:


Tornadoes do not need to hit a metro area's "downtown" to be deadly or very destructive. Many buildings in the dense commercial core would have more resistance to strong tornadoes. I'd suggest that the worse areas to have hit by the tornado are away from the downtown area, where most people live.



I disagree, I don't think downtown areas would fare very well during a strong tornado, on top of that you have more material to become dangerous flying debris or building material to crush people.

Now considering the time which the tornado hit, downtown areas may mean less deaths late at night because there would be less people, but I assure you a downtown area could mean mass loss of life during afternoon commuting hours. The strongest downtown buildings would still be shredded apart even if the main structural frame holds intact. I think you are forgetting just what a high end tornado is capable of doing, I wouldn't put too much hope in any building above ground when it comes to high end tornadoes. Buildings frequently fail before their supposed standards. The Hospital in Joplin is about as strong of a structure as you are going to find, it didn't even take a direct hit from the tornado, yet it still was a total loss even with the structural frame remaining mostly intact.

The Hospital in Joplin is what would happen to the strongest downtown structures, but even then, most of the commercial sector is composed of high rise building with massive amounts of glass that are not as strong as the hospital was in Joplin, an EF4 to EF5 range tornado would leave many of them with very heavy damage or total loss.

That is exactly what is likely to happen. One thing to bear in mind that even if the system gets below 1000mb, it could still have a front attached - which is likely. Also, if it doesn't become warm-core... same situation.

Many people on here seem to forget that it isn't just about pressure or winds... it's also about the overall environment, other weather features (like fronts), and the nature of the system itself. Just like SSTs aren't the only factor in TC development, pressure and winds aren't the only factor in whether a storm gets named.
