According Meteorologist-in-Charge of the National Weather Service
Shreveport Weather Forecast Office
Shreveport, LA
"Meteorologists do use probability in their jobs. The probability of measurable rain, for example, is determined by a forecaster's confidence that a weather system will produce rainfall, multiplied by the amount of the area the forecaster thinks will be affected by the rainfall. For example, with a cold front moving through, the forecaster's confidence that it will produce rainfall is 80% (0.80), but only half (0.50) the area will be affected. The product of 0.80 times 0.50 is 0.40 or a 40% chance of rain."

If there is a 60% chance of rain that means 6 out of 10 times it will rain, but does not say how much rain is going to fall when it does.

This has nothing to do with the amount of rain that will fall. It is simply probability. The weatherman is saying there is a 60% chance there will be any rain over a given area. Therefore a 60% chance of rain means that there could be one drop of rain up to 10 inches of rain or more.

Good question. It may rain a little or it may be a heavy rain. The probability is simply an indicator that under similar weather conditions, there would be this likelihood of rain at any location within the forecast area that many times out of 100. These probability forecasts for precipitation look at the existing conditions and the numerical weather prediction output at the time the forecast is being prepared. It allows the consumer of weather information to make a more informed decision about their planning. For example with a 60% probability of rain I probably would not plan a picnic for the valid time of the forecast.

?????? Not relevant information to determine the other. Chance of rain can only be one of two possibilities. Either it will (100% chance of rain) or wont (0% chance of rain). The measurement values are Absolute 0 to 1.
The second part - how much does it rain? is independent of the first part of your sentence. You cannot determine the amount of rainfall from this info. (Unless the chance of rain is zero. Only then are you able to determine how much rain there will be - the answer of course - None.
You asked this as a trick Question didnt you??? It was quite a good one, but I passed...lol

I wondered about that - will it rain 60% of the time? Will it rain on 60% of the land? The answer is: there is a 60% chance that it will rain at all anywhere.

The amount of rain isn't indicated. 60% chance of rain means given the exact same atmospheric conditions, it will rain 60 times out of 100 times. It is a statistical forecast, and pretty much the best a meteorologist will be able to do, given the complexities of the weather.

There's no way of telling. In 10 days, it will rain on 6 of them. But there is no telling how much rain will fall - it might be light rain or heavy.

When it rains is like if u just get onto the shower but just 4 a few mins, rain is warm and if u got wet ull b dry again in other 5 mins so rain isnt really a problem at all :D

Sometimes none, sometimes a lot. The percent chance is only an estimation of IF it will rain, not how much.
