The controller would download weather info from NOAA 1 hour before a schedule run if you enabled the weather feature. It will ask for data for the next X hours in the forecast range number. In your case, it the forecast says there's a 61% chance or higher of rain, the run is cancelled. It may rain in your area, but the forecast probably said less than 60%. Remember, it's only a forecast and it may not be 100% accurate.
If it is cancelled, you will see it in Today's run. The controller does log cancelled runs, but does not show it at this time. We have plans to show the weather data and cancelled runs in future firmware release.
