We were driving from Wichita Falls to Lawton once, years ago, and were in the middle of nowhere and were in a tornado watch, which just means conditions are right for tornadic activity.. I looked over the countryside and saw THE most perfect wall cloud.. it looked EXACLTY like an anvil with lightning in the front "shelf".. Unfortunately I didn't have a camera with me.. I have never seen a more perfect wall cloud than that one..

So, here's the closest I can find, which was from wiki.. It kind of look slike an anvil and has lighting coming out from under the front shelf thingy.. Where the lightning is, is where the tornado will form.. Usually with tornados you get MASSIVE hail..

Hail is described as a drop of water that freezes and falls to earth, but depending on how STRONG the system is, it will get sucked back up into the system, where more water freezes to it, its gets a little larger, and falls back toward the ground.. You can tell how strong a system is by how large the hail is.. the system will keep sucking the hail pellet back upward to get larger until the system is not strong enough to suck it back upward.. at that point, the hail will fall to the ground.. if you have HUGE hail,t hen you have a MASSIVE system that was strong enough to suck that hail stone up a bunch of times.. Small hail is indicative of a weak system - not strong enough to suck the hail stone back up..

Its the systems that are strong enough to create HUGE hail that are strong enough to create tornados, which is why you usually have MASSIVE hail before most tornados.. Herre' a pic of that wall cloud with the lightning.. Like I said, the tornado will form where the lightning is, under the front of the system.. this is NOT a very good wall cloud photo, but you can kinda make out the hsape of an anvil..
