Well, the sirens just went off, and the southern half of my county (my half) is under a tornado watch.
It's matching what the tv guys are saying right now--pretty unthreatening right overhead, but there's some impressive, powerful-looking stuff marching along the eastern horizon. (I took a picture out the window.)
At least it's breaking early, from what they're saying, the most violent stuff should be past by 7 pm or so...
(I have weird tastes about what counts as positive, don't I?)
