@franz thank you so much for all of the answers and support (on all of my questions)!
One more question for this topic though:
Where would I see this text? The web app, mobile apps, everywhere? I am not seeing that tag on any weather stations. It could of course be that all of the ones I've looked at are recording precip data, but according to wunderground (for whatever that's worth in this research) I've found a few that appear to have no precip history but don't display that text. (See the wunderground station data graphs below; 1st pic: zone w/ precip data vs 2nd zone with no precip data.)
Am I being overly concerned about this? I just know the weather at my house can vary significantly from the weather only a couple miles away (especially when it comes to wind and precip) and want to feed the Iro the best data (until I invest in my own PWS). As a smart man once said: garbage in, garbage out!
