Ty explains what a Derecho is - the weather phenomena, not the Spanish word.

Ty talks about one of his nicknames.  Also, Tornados on Water.

Ty tells us about Tornados and the Fajita Scale.  Did you know most tornados are in the US?

Ty explains the Polar Vortex and what happens when the Polar Vortex weakens.  Is there a polar vortex on the South Pole?  Does it spin the opposite direction?  Could cold air from outer space get sucked into the north pole or is that just in the movies?

Ty talks about Lenticular Clouds (which is what they're called outside of Area 51).  

Ty describes Volcanic Lightning.  Kinda like when you rub a balloon on your head and then touch a piece of metal.  First recorded when Mount Vesuvius went boom in 79 AD. Then, just to get really crazy, we talk about Volcanic Hail.

Ty gives a few fun facts about Hail. A record-setting hailstone that fell in Vivian, South Dakota on July 23, 2010. Then we get distracted by that place in South Dakota with the Rocks and the Presidents.

Ty explains Mammatus "Look like Butts" Clouds to his Dad.
