The chance for rain at 5 pm is very high in the early morning, but then it decreases as the time gets closer to 5 pm. It almost never increases. It happens so often that I believe that the forecasters are intentionally publishing a higher chance for rain in the morning than the data actually suggests. Has anyone else noticed this trend and is there a logical explanation?

In general - the greater the time-frame, the greater the probability. At 6 AM the probability of sunshine is high, while at 6 PM the probability of sunshine is low.
