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.

Figure 2. This tornado sparked a fire in Oklahoma as it passed through the area northeast of Woodward. Image credit: news9.com

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.

Video 1. Storm chaser video of one of Saturday's impressive tornadoes near Salina, Kansas.

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."

Very severe cell. Bottom of the line near the Mexico border in Texas. Zapata TX 63 dBZ 49,000 ft. 75 kg/m� 80% Chance 100% Chance 2.00 in. 6 knots S (172) I don't even think it's got a warning yet.

In case this hasn't been posted yet (I've been away most of the day), here's a short but great video of a "drillbit" tornado from yesterday. Watch it in full-screen HD to get the full effect; the best part begins at about 0:58. Yowsa...

Don't know if Corpus and Brownsville radars are just hot or what, Houston radar shows less near Victoria for 1 hr running totals.

In fact the Houston radar is always less aggressive on echos and running totals period. The line is only moving 2 knots. It seems to have almost unlimited moisture available. VIL is just as high as before it even started raining there. It's possible the radars are looking too high and looking directly at hail cores or something... ...but the brownsville radar should have an un-obstructed view of all the cells, since it doesn't have to look "through" any of them to see the others.

It's gotta be for real. Flash Flood warning just went up for the Zapata cell. The cells to the north are weakening and haven't rained quite as much, but they may get a warning too. Edit: Continues with 5.8inch per hour running total. Has 7.6inch storm total now. Edit: VIL is higher than when the storm started!

Frontal surface low at 1200Z TAFB was 1013 mb Frontal surface low at 1800Z TAFB was 1012 mb Frontal surface low at 0000Z TAFB was 1011 mb Looks like our pre-subtropical cyclone is deepening by 1 mb every six hours so far. This deepening rate could accelerate as the cut-off upper trough continues to amplify, which in turn will increase the divergence over the surface low.

Quoting beell: Shallow warm-core is good enough for the NHC. They'll call it Sub-tropical so as long as it's a warm core they'll designate it, or recognize that it has potential. It'll be a close call, Around Tuesday is when it should be at it's best if it's not designated by Wednesday night, then it has no chance of becoming our Alberto.

Quoting DavidHOUTX: Cap over SE Texas is eroding fast Hah...and this from the guy who reported bitterly earlier that the cap was firmly in place...LOL. Hopefully you will get some needed in rain in Houston. Did the Victoria or Goliad supercell ever get tornado warned? From the discussions here...sounds like it didn't...
