no source needed , just look at the number of days it doesn’t rain . but if you want one it’s the national center for environmental predictionsSource please.
Using the equation, here’s how the FOX weather team may determine the chance for rain on a particular day.
If we’re 100% certain that rain will develop in the Piedmont Triad but it’s only expected to cover 30% of the forecast area, then the forecast would read “a 30% chance of rain.”
This is because our confidence is 100% and it’s multiplied by coverage in decimal form, 0.30, which equals 30%.
Alternatively, if we’re 60% certain that rain will develop or move into some area of the Piedmont Triad but it’ll only cover 50% of the forecast area, then the forecast would again read “a 30% chance of rain.”
SO forecasters are really not accurate about the weather in any particular spot . they go by vast areas and for any given day are wrong more than right n any exact spot
