Tornado alerts are just that conditions are right for tornadoes, while tornado warnings mean one has touched down and has been spotted.. Tornado alerts don't even get our attention.. Really, tornado warnings don't either - you hafta actually see one to be alarmed and, even then, I'm grabbing the camera and climbing on the roof..
Tornados are spawned out of wall clouds.. since you might have the view of a large area of open land, a wall cloud doesn't look like a wall.. it looks EXACTLY like an anvil nd the tornado will spawn underneath the front ridge, where all the lightning usually is..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
