How's the weather?

The following was taken directly from WNDU.com on 6/5/08

(tomorrow) "There is a chance for a t'storm late in the day, possibly heavy in spots."
(tomorrow night) "Showers and t'storms likely early, possibly heavy or severe. Still a chance of t'storms overnight."
(saturday) "Slight chance of a t'storm, especially south."

That is far too many chances, possiblies, and likelies. I am, however, overwhelmed by the especially!

How can someone even predict that storms could possibly be heavy in spots when there's only a chance that they will even exist? That concept blows my mind. Does a likely have more gumption than a chance? BUT...If there is a chance for thunderstorms on Saturday, they may or may not exist especially in the south? Huh?

So basically...
It may or man not rain a little or a lot.
It may or may not thunder, lightning, be cool or be hot.
It may or may not do this in the south.
It may or may not do this over my house.
Do I find a nearby shelter, or move up further north?
What kind of effort does this weatherman put forth?
He may or may not make six figures doing this.
But his predictions especially aren't worth a piss.
