Some local television stations have been shown as having significantly greater wet bias, often reporting a 100% probability of precipitation in cases where it rains only 70% of the time.
[4][5] Floehr found that the commercial forecasts were biased: they consistently predicted a higher probability of precipitation than actually occurred.
[1][4][6][7] Blogger Dan Allan noted that The Weather Channel is also biased at the upper end: a probability of 90% or higher will be rounded up to 100%.
According to Silver, The Weather Channel has openly admitted to deliberately exaggerating the probability of precipitation when it is low.
Silver quotes Dr. Rose of The Weather Channel as saying, "If the forecast was objective, if it has zero bias in precipitation, we are in trouble.
