Which of these is a weather front?

A tornado is not a storm front. A storm front is a delineation of pressure areas. These can sawn tornados, but a product of a storm front is not the front.

Go to Texas, Iowa or Kansas if you want to see one

I've been through tornadoes in Wisconsin, Iowa, Texas, and Florida, plus two hurricanes in Florida that spawned who knows how many tornadoes. Storms are scary fun and sometimes amazing to watch

I agree with Dan. While a tornado may be a product of a storm front, it's not known in meteorology as a storm front in and of itself. Too, winds from three directions must be present to produce a tornado, which commonly begins horizontally before becoming vertical.

Dan, thank you, When we used Hence cold front moving in from say Russia.

Dano, and Oklahoma
