Why doesn't the weather forecast in Beijing report the precipitation probability now?

I think professional data such as precipitation probability should be used for internal communication of meteorological stations. Forecasters will weigh various data before telling the public whether it will rain in the weather forecast.

The probability of reporting precipitation makes people think that the meteorological bureau doesn't know whether it will rain or not. Tell us an intermediate data for us to estimate! Just tell us the original data.
