What is the formula for chance of rain?
Meteorologists calculate the Probability of Precipitation (PoP) using a simple formula: PoP = C x A. Where “C” stands for the confidence a forecaster has that rain will occur somewhere in the forecast area, and “A” stands for the percentage of the area where they expect a measurable amount of rain to occur.What does 80% chance of rain mean?
That's because weather forecasts give their “percentage chance” in probabilities. The answer? An “80% chance of rain” means that there is an 80% chance that rain will fall somewhere within the forecasted area. Rain refers to 0.01 inch or more.What is a 70% chance of rain?
40%-50% - SCATTERED - Roughly half of the area will encounter a shower or storm. 60%-70% - NUMEROUS - Much of the area is covered so it's likely you will get wet. 80%-100% - WIDESPREAD - The entire area is covered with showers and storms so everyone gets rain- If a forecast for a given county says that there is a 40% chance of rain this afternoon, then there is a 40% chance of rain at any point in the county from noon to 6 p.m. local time.
