You are probably using a Davis station. Cumulus needs an incrementing rain counter to calculate all of the rain figures, and the nearest to that on a Davis station is the annual total. When this resets at the end of the year, this causes some of the rain data to show odd values for a day. You will notice this particularly if you use an 0900 start of meteorological day, as the 'rain since midnight' figure is used for services such as Weather Underground. There's no easy solution to this, sorry.
