A very interesting setup will prevail across southwest KS and the OK/TX Panhandles today, with strong tornadoes possible by late afternoon/evening as the low-level jet intensifies. A warm front will be extending WNW to ESE across central KS by 7:00 pm, with a dryline extending south across the central Panhandles. Low-level shear and CAPE will be maximized over the eastern TX Panhandle, but southwest KS and southeast CO also have sufficient shear/instability for tornadoes. Shown below is the RUC forecast 0-1 km EHI (left) and 4 km WRF forecast precip for 00z this evening.
The SPC has issued a moderate risk for this area, along with a threat for significant tornadoes. Based on the RUC and 12 z WRF this morning, we favor the eastern TX Panhandle if a storm will initiate that far south. However, our plan is to still keep southwest KS in play just in case storms do not initiate further south. STAY TUNED!

Stu, Dave W and myself will be out today. targetting north TX panhandle area. Will call u in a bit.
I can't wait to see how strong this is.This will be a great time to learn about how/when stroms start to develop
Good luck, and bring us back some great video :)
Does anyone know how large the Tulia tornado was on the Fujita Scale???????
Well if you take a literal meaning of what Reed said,("large violent") it was F4-F5 I think (weak=f0-f1, strong=f2-f3, and violent =f4-f5, from what I heard)
I haven't gotten used to the new EF scale, so I don't know how that ranks them.
Wow, looks like the apocolypse is going to occur today. It looks so calm right now. Shall be interesting to see how the storms explode over Texas and Oklahoma. Looks like the storms will really kick in when I'm off work, so I'll have to rely on my slow ass dial up connection when I get home. lol
Time for you to switch to verizon fios :)
Jacob im thinking more like ef3 although some houses were completely destroyed they looked pretty weak constructed.

O boy o boy, exciting day. See that u just left home, I'll keep an close eye on you guys, and wish u all good luck.
Less sleep for me tonight, 9 o'clock in the evening here already, and no active supercells atm.
yep het wordt een latertje vanavond ;)
Is it possible to have a tornado outbrake? And what
is a cold-core landspout?
when I was 8 I saw a tornado. But the good part is It
didnot hit my house.
Hey guys, This looks fun, But Im getting excited about tommorow for DFW Too, Discreate cells on the dryline. Large hail and good structure, Tornadoes would be nice but I dont want any tornadoes coming near my house, just got a new dog, and we almost had to put her in the closet on the 13th. oh boy lol
Anyone think St.Louis will get any severe weather or will it miss us i hope we get something tomorrow...
Sorry for not typing english:
Hé Cors grappig jij ook uit Nederland, we delen dezelfde passie. Ben jij al eens in Amerika geweest voor storm chasing? Voor mij is het in ieder geval een toekomst plan/droom.
yea im planning on going stromchasing in the US...i might be going pretty soon :P although i realize it's a pretty slim chance of actually seeing a tornado.
PANHANDLE AGAIN!!! You need to get an apartment out there for just the storm season. Save on gas!!!
Hope you guys get some awesome video!!!
GO IN THE RIGHT DIRECTION!!! Will be checking you guys out!
Hey what time did they depart anyone know?
I can't get the GPS tracker to work...it was working earlier but now this little pop window comes up saying "stack flow:0"...wtf????
Looks like those supercells west of oklahoma city are really starting to fire up
TVS just popped up in colorado...interesting....these storms are quickly buidling with intensity...woohoo!
AAAAAAAAA bit to far to the west..go Reed go
tornado warning nw of oklahoma city!
exploding supercell near Midland!
These storms are just popping up outt of nowhere! there's still a TVS popping up every so offten in Colordo...
it's happening! :P
Looks like Reed has found a target
I wonder if they are really stoped on interstate 40? they have been stoped for awhile. They might be observing that one cell that just poped up next to them.
yep they re in it now :P
I think they are in the perfect spot right now. Go get em fellas!!!
It's a severe thunderstorm now. How long before the tornado. I give it 15 min.
Shawna - Restart your browser. If that does not work you might need to reboot your PC. Sorry, I think there could be a little memory leak issue with the tracker if you have it pulled up for extended periods. We are looking into a little better implementation of the tracker, but it will take some time to develop.
I hope a tornado doesnot hit St.Louis. Because sooner
or later a EF5 tornado will hit the city. winds would be over 250MPH!!!.
tornado warning on that cell Reed is in! wonder if he called it in,,,
REEDS CELL JUST TORNADO WARNED!
A bit of a small cell, must be a great site! I want to see that compared to the size :)
dang it was only 5 min. Ya, Reed probably called it in.
COOL Hope one Is on the ground!
SET a probe In the path of the tornado GO!! REED!! GO!!
It's about 7:49 pm and on the weather channel there
talking about a twister in 1967.
Thanks Jason, that worked! The GPS is workin again! woohoo!
what gps???
That cell they're near looks like it's startin to weaken...they need to go south! there's a monster supercell forming south of them....two counties have tornado warnings.
If this supercell going to create a tornado? If it does
tell me how strong It was
Don't know if it will create a tornado, but it's very possible. TVS already poppped up once or twice. Okay guys i'm off work. i'm headig home now. i'll log onto my crappy dial up oncec i'm home to keep track of the storms. lata
Looks like its going right over Pampa which reminds me of an old chase of Reed ;) check it out:

I can't find it on youtube
sorry I did see this on youtube this morning.
richard that might be a tornado in mexico.
nasty storm south of lobock tx possable rotation and hail.
Large and Extremly Dangerous tornado just moved through Colorado City. I have radar images as the storm was "Redevloping"
Went from no hook to hook to MAJOR hook and 3.75 hail. I have images as it formed west, moved through, and now east of the city.
dryline just backed up through Lubbock and dew point went up to 59 what is the likelihood of tornadic storms tonight. There have been some nasty storms to the southeast of Lubbock.
Good lord..
Look at the tremendous hook echo on this monster!

Can only hope the people in the vicinity of Colby, Kansas have taken cover as a very large tornado is likely on the ground at this time.
Hook not as evident now, but storm relative velocity continues to show VERY strong rotation.
Hook echo has redeveloped nicely!

Also the cell just west of the Abilene, Texas area is nasty showing rotation also.
wow, monster supercell to the east of goodland with a beautiful hook. It has split into two supercells!
Yeah Robbie, that's the cell I've been tracking for well over an hour.
If this cell continues to produce a tornado the people in Atwood, Kansas may be in some trouble.
This cell is going NUTS!
Now 2 hook echos
Storm relative velocity shows what appears to be 2 couplets (areas of rotation) SW of Atwood, Kansas.

Cell just south of Spur, Texas showing rotation on Storm Relative Velocity.
Rotation noted now on the cell just south of Spur, Texas.

I'm sorry that my links run so long.
I'm a newbie to this site, yet have an endless passion for severe weather and tracking it.
Rob
Very strong rotation on radar just east of Yuma, Colorado
Where is everyone?
Tremendous hook echo has developed on the cell I've been tracking for the last 2-3 hours.
Atwood, Kansas may be in some serious trouble.

Look at that!.
Now this is the rotation on Storm Relative Velocity!
I can only estimate this is a very large tornado.
