Please educate yourself Mr. Smelly. The balloons don't tell the weather pros and the rest of us what the weather is or is going to be. To date, weather balloons remain the best method meteorologists have to access site-specific data on temperature, winds, relative humidity etc. The weather pros use this and other data to develop their forecasts. If you have a better idea about how to collect site-specific weather data that the pros can analyze and use to develop weather forecasts, please let the rest of us know what that might be.
