Featured in Nate Silver’s bestselling book The Signal and the Noise, Professor Eric Bickel analyzes over 13 million probability of precipitation (PoP) forecasts provided by The Weather Channel (TWC) in this paper. He found that while TWC performs well overall, for forecasts of less than six days in advance, they tend to over forecast low chances of precipitation and artificially avoid forecasts of 50%, he also uncovered motivational bias.
