This is the same storm I thought I was seeing a small appendage form out from. I'm using GRAnalyst and on occasion, it's dumping MDA icons. Storm Relative Velocity is showing some good wind signatures running around -50/+50 inside this guy.

And just as I type, cells close enough to me to warrant a Severe T-Storm Warning.

A wedge? That is dangerous!

WOW.

and the air is rather stable up there and it's nighttime. Needless to say, I am very concerned about tomorrow here.

:sick:

I know. Had the cap busted farther south and able to tap directly into that energy. Oh boy. Tomorrow just got VERY interesting.

#93 Postby **CrazyC83** » Wed Feb 28, 2007 8:44 pm

This could be VERY bad folks!

The action isn't over further south yet either.

"3 TORNADOES COMBINED INTO 1 WEDGE" I'm confused, 3 tornadoes merged? what is a wedge? a wedge shaped supertornado?

whats happens when a cap is broke?

sorry for the probably stupid questions.

Stay safe in KS!

snoopj · #96 Postby **snoopj** » Wed Feb 28, 2007 8:48 pm

I know. But I'm not seeing the cap erode rapidly either.

Classic hook echo. This could easily put down an EF3 at least...

#98 Postby **simplykristi** » Wed Feb 28, 2007 8:56 pm

There are trained spotters all over the storm in Linn COunty KS.

You essentially get what is called a multi-vortex tornado. There's more than one circulation in that tornado. When those combine, you tend to start seeing some high end damage.

fact789 wrote:whats happens when a cap is broke?

From my understanding, the "cap" is a inhibitor for convection. This is keeping storms from forming even though all the factors say they should be forming. Once a "cap" disappears, you get free range for thunderstorms to rapidly form.

From what a few of us are looking at, some of the areas to the south have the ingredients necessary for explosive thunderstorm development, however, this inhibitor ("cap") is keeping it from happening.

I just hope I answered your questions correctly!

A cap is like a lid. It keeps storms from forming. When it breaks, then that allows them to develop(and they can do it VERY rapidly). When you have a setup for tornadoes like this, that's a real problem.
