I agree they are shifting east. Of course being old I remember some really bad tornados. But we haven't had many here in Oklahoma since the one in El Reno in 2013. I think it has to do with the earth shifting on it's axis during that huge earthquake in Sri Lanka. I think they said it shifted 4 degrees or about 40 miles. Tornados mostly travel the jet stream. If a cold or usually warm front comes in it stalls at the jet stream and if conditions are right, moisture, humidity, heat ect then a tornado will likely occur. Like I said the Doppler and TORCON system needs to be put in place further east now. Saying here "If the TORCON is high, watch the sky."
On another note, storm shelters and safe rooms are not that expensive. Safe rooms (which are the best since they can be installed in any room in the house) are sold at places like Home Depot and Lowes and easy to install in your house. Some for 1-2 people can be bought here cheaply and are priceless. Or if you can weld make your own.

I think a lot of the fatalities further east is due to people not being educated on tornado safety.
1. If you are in a car GET OUT!!!! You are safer lying flat on the ground and covering your head. Cars are death traps in a tornado and you cannot outrun one. You never know which way it will turn. I have seen them turn and double back on themselves going over the same area again.
2. If you are in a mobile home or trailer house GET OUT!!!! Those things are shredded even in an F2. Get to a neighbors house or shelter such as a school or other designated shelter.
3. If you live in a constructed home get to an interior room like a bathroom or closet. Preferably one with no windows. Cover yourself with blankets or a mattress. Get into the bathtub and cover yourself with a mattress. Many people have rode out a tornado in a bathtub with a mattress off their bed over them.
Remember people are killed by flying debris during a tornado. So get somewhere that anything flying through the air can't hit you.
Cover your head!!!!!!!!! Keep motorcycle helmets available for all members of your household. Good ones that cover your entire head. It could mean the difference between your surviving or dying.
Buy and have installed a certified storm cellar or safe room. Basements can offer some protection but remember the ceiling above your head is wood so it can collapse on you. Wouldn't recommend using the crawl space under your home either since you could end up with the entire house sitting on you if the tornado shifts your home off it's foundation.
