How is the probability of rain calculated?
Probability of precipitation is the forecast of >0.0254 cm (0.01 in.) … PoP = C x A where “C” = the confidence that precipitation will occur somewhere in the forecast area, and where “A” = the percent of the area that will receive measurable precipitation, if it occurs at all.
What does percentage mean?
%In mathematics, a percentage (from Latin per centum “by a hundred”) is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, “%”, although the abbreviations “pct.”, “pct” and sometimes “pc” are also used.
What does pop rain mean?

It is often published with weather forecasts.

Is 70 percent chance of rain high?
To answer you question, “70% chance of rain” does not mean it will rain all day. It means there is a 70% CHANCE that it will rain at some point – maybe a 10 second sprinkle, maybe a four hour downpour – or maybe you’ll get lucky and it won’t rain at all.
