Tornadoes and severe storms tonight for example???

Question

So here in Omaha Nebraska it has been a very busy night for severe weather North and West of us Here is what i dont understand a couple things. Why everytime we get severe weather does it always miss Omaha even when we have the most unstable air everything goes north south east or west of us or by the time it gets here it weakens. Also apparently tonight was a very dangerous night due to a warmfront Our local T.V station says the warmfront causes Supercell and long trac tornadoes??? But i was always told a coldfront causes tornadoes so how does a warm and cold front both produce tornades?? Also you cant really predict this but Does anyone know or think Omaha could see Another Tornado outbreak like this with supercells this year???? I was told by a Meteorologist we have a very good chance of seeing a lot of Tornado outbreaks in Eastern Nebraska this year??

Answer 1

I also want to the meteorologist above... Storms that become severe, become more dominant that they can remove the energy in their vicinity, and cause it to weaken or even dissipate.

Answer 2

AGGGGGGGGGGG I wonder the same thing!!!!!!!!!!!! I live in omaha

the last one we had was 74 and I do believe we will get another large tornado in the future

oh but over all I think omaha is in some strange ozone that protects omaha because thats the only thing I can come up with why we avoid any extreme weather

Answer 3

They may seem to miss Omaha, but it is only a matter of time.  There is no geographic "protection" for Omaha.  Note that even strong tornadoes are still relatively small compared to the parent thunderstorm, and typically do not last very long, thus it is easy (fortunately) to be missed.  

Another factor is that severe thunderstorms that produce tornadoes tend to produce them early in the storm's life, which in today's case was when they were growing across central Nebraska.  

Fronts tend to act as focusing mechanisms for thunderstorm growth, and the type of front itself is not really a determining factor in what type of storm occurs.  Supercell storms are simply thunderstorms that contain a rotating updraft.  This normally occurs as a result of winds that change both speed and direction as altitude increases, especially in the lower few miles of the atmosphere.  This is known as shear, which is what normally aids a storm in becoming supercellular.
