There's a 30% chance it will rain, 70% chance it won't. Most likely won't rain, but if it does, the meteorologist is covered.

okay in meteorlogy class last year someone had the same question someone asked "if the meteorologist says that there's a 20% chance that its going to rain should we go on a picnic or something"
my teacher said that when they say 30% chance or whatever percent it means its for the prjected area in the forecast. so if there's a 30% chance for a 100 mile radius, you may or may not see the rain. It not only for your town, but for the whole are. like it could be raining in the town/city next to you, adn in your city/town it may be only parlty cloudy with some sunshine.
The best way to decide wheteher or not its going to rain is just to keep a lookout on you LOCAL weather. and look at the radar to see if there is any cells (rain) heading your way.
but 30% chance merely means its for the projected area. not matter how big or large it is. it could rain or it could not.
hope this helps! =) even though it sounds confusing i did my best to explain it! =p
my teacher also surprisingly said that weather forecasters/meteorologist are over 70% right at any time.

I'll assume you meant to write '30% chance'.
Meteorologists use past weather data to make forecasts. Saying that there's a 30% chance of rain means that of the previous 100 days where the weather conditions of temperature, relative humidity, barometric pressure, whether the barometric pressure is rising, steady, or falling, and the dew point, are the same as the forecasted day, it rained on 30 of those days.

30% chance means that the weather guy doesn't know what is going to happen, but there is a storm in the area that may blow your way. I would say check the percentage for the next couple of days. If the percentage goes up then the rain is coming, just at a slow speed. If it drops then you may get the outside of the storm. I just stick to the old method, look outside and if looks good, enjoy it. If it is going to rain, keep a back up plan.

It means that there will be rain over 30% of the area, if you are in that 30%, you get rain. Now that should be clarified, if they say it will rain, it will rain all over (no percent). Chance of showers is just that, a chance of showers. No Percent attached because the cloud coverage is such as to not be able to predict the % chance.

It means that in the past, current or predicted weather conditions have led to rain about 30% of the time. Basically if you were to have 100 days of the same weather conditions, you would expect to see rain on 30 of them.

Wesather frocasters are not odds makers. The percent chance means that for the forcasted conditions you could expect rain in 30% of the AREA involved in the forcast.

It means out of 10 days, there is a chance for rain three of those days.

70 percent no rain.

The second sentence of Matthew I is the exact meaning of the topic.
