To me, I think they should only blow the siren if one is spotted not if "one may be produced ".

But, I also know that they would catch hell if a tornado came and they didn't sound. So they sound them just in case.

I just heard that on the one in Moore, the siren sounded "only 16 minutes before the tornado was produced"

That's the danger of it
and be aware that THEY're aware of that too;
it's called, "The-Boy-That-Cried-Wolf-Syndrome".

The danger, of course, is only realized AFTER
the Wolf Shows Up @ Your Door.

As you yourself pointed out,
15 minutes isn't nearly enough time to bug-out.
