Tornados: a Primer
How do tornadoes form
The Feb. 26 Tornado in Tidewater VA
The "evil meteorologist convoy" from Twister (look at that GMC RV in the back!!!)
Outro music, "Shania Twain - No One Needs To Know" from the Twister Soundtrack.
(Apparently the music video was shot in the house that you saw in the movie Twister that they "aunt"(?) lived in).
