So far as I can discern, the NOAA/NWS provide forecasts for certain time windows that are coherent probabilities, see the last post there. Then the popular news services use invalid methods (I don't know exactly what) to obtain their "probabilities" for shorter or longer time periods. I think that the numbers that you see on popular news services for hourly probabilities are essentially nonsense.
But The Weather Channel and other such services do the same thing. Are you saying The Weather Channel is spouting nonsense?
