Tornado WHAT?

I just got a couple of alerts on my phone about a tornado watch, starting now. It struck me as kind of strange, since outside I see clear blue skies, a few scattered clouds, and a beautiful sun.

The National Weather Service says the same thing:

tornado-watch

Who knew? Of course I rode my bike today. Should I head home now, when it’s nice outside, or risk riding through a tornado in a few hours?
