100% chance of weather

I have this nifty dashboard widget (it's a Mac thang) that at the push of a button zooms the current local radar onto my computer desktop. And the radar my Mac is zooming at me right this moment is quite interesting. If you could see it in motion, you would see that all those little red and yellow spots are moving in such a way as to suggest they might be thinking about converging right on SPI. At the very least we could see rain. Tonight or tomorrow.
We need rain. I mean we really need rain. We need rain right now - hard and quick and get it over in time for our MeetFRED open-house garden party on Thursday. Hard, but not so hard that it knocks the bejesus out of the sand sculpture I have really been enjoying working on in the backyard sandbox. Just enough to give the plants a good deep drink and put a dewy glow on everything and bring joy and cause for celebration to farmers, birds and the rest of the flora and fauna. And then go away, By 5:30 thursday afternoon.
That's what would happen of I was queen of everything, anyway.
