Well, it DID rain today, but the weather page was reporting a steady and slow rain for several hours. Oops… Brando screwed that one up. Somehow, I have been graphing and displaying all this time an artificially calculated rain rate. The guy who originally wrote the scripts did some stuff on rain rates that worked for him.
I yanked that calc out and made it look at the console calculated rate instead. Works like a hose now.
