The POP (possibility of precipitation) numbers are derived by multilplying the degree of a predicting entity’s confidence that it will rain by that same entity’s estimate of what percentage of its coverage area will experience that rain. If a weatherman is 100% sure that it will rain over 50% of the area under consideration, the POP will be 100%x50% (1.00×.50) or 50%
