Is the Flex scheduling still only using NWS and not PWS for its precipitation totals?
it will use whatever you have selected as your weather station
PWS will be used for everything. I have seen cases whereby the PWS reported data is bad (i.e. Min/Max temperatures the same) which result in evapotranspiration daily totals of zero. In this case, we use a NWS. If you look at the soil moisture chart it will show the station used for the observed data.
