I too use the IP data lager and that has no bearing on your issue. Modifying MTD and YTD Rain on your console as described above will fix your issue. Interesting enough, if you want to increase Daily Rain on your console, and you modify it before midnight, it will also increment MTD and YTD Rain. However, if you want to decrease daily rain, modifying Daily Rain on the console does not auto correct MTD and YTD. IN that case, you use WeatherCat's Rain Editor to modify rain for the date you want to decrease, and then manually change MTD and YTD on the console so that the console and the WeatherCat reports all match up.
