A further followup about PWSs and forecasts --
I am running on a fixed schedule (due to drought restrictions) and I have selected a local PWS. The Weather Intelligence features seem to be working as intended, since I sometimes see updates such as:
Water all zones (PM) skipped since station PWS_PAULCROSS4 observed 0.37
in and predicted 0.1 in of precipitation with a total threshold of 0.125
This is fine, but I am still having trouble understanding where these numbers come from. If I view the PWS's details at pwsweather.com, I can see the historical precipitation amounts, but I have no idea over what time frame the "observed 0.37 in" was measured. Additionally, there is nothing at the PWS about a forecast, so I have no idea where the "predicted 0.1 in" comes from.
Can you be a little more specific about where the precipitation observations and forecasts come from, and over what time frames they apply?
