I finally found what I've been looking for - a mobile app that has 24 - 72 hour past precipitation data that's visual, easy and faster than web data or RealEarth app layers. It's from UC Irvine and rather a gift to the world much like University Of Wisconsin's RealEarth. https://apps.apple.com/us/app/irain-uci/id982858283 https://play.google.com/store/apps/details?id=irain.app&hl=en_US I don't agree with some of the negative reviews because the weather, climate, and seasonal data and services we get from academia and government agencies are really valuable for a lot of businesses. I have friends in farming and transportation who rely on it. In this case knowing past rain helps my being a small ski area director and MTB trail manager. For both of these systems and especially RealEarth check out the desktop web sites too. RealEarth has hundreds of data layers you put over a Google Earth base map. This iRain app quickly took me from using the RealEarth storm total layer to it because it shows shorter and longer periods of time.
