How do weather forecasters keep their jobs?

Forecasting weather is and never will be 100% accurate. Weather forecasts for 4 days or more are generally less accurate than a forecast for tomorrow or the next 2 days. Weather is ever changing. Don't bash what you don't understand.

When you read a weather forecast, you witness a feast of worldwide cooperation and scientific achievement! Am I using too much superlatives for you? Perhaps but consider this:

It is only by drawing a synoptic map of the present weather that the future one can be predicted. That is done by the World Meteorological Organization, a division of the United Nations, that gathers then redistributes all worldwide observations. Then those are fed into computer models like the NOAA's Global Forecast System. The output is then made available to any weather forecast provider. Some, like aviation forecast, will perhaps concentrate on the cloud ceiling, while that for seafarers will give the wave height.

The layman usually wants the short version: "sunny today!" or something like that. The point is, weather forecasting is more complex than that. When I go flying my little aircraft and the forecast says: 30 percent chances of thunderstorms, I know that I risk to have to change my plans and perhaps fly somewhere else. It can be a matter of life and death.

But it is not for you and perhaps this is why you don't read the "small print" and feel that the forecast is inaccurate. Learn about meteorology, my friend. Then read the raw data like, aviation METAR and TAF and make your own forecast. You will then see that it always happens within a cone of accuracy.

An employer would have good cause to fire you for being wrong as often as you percieve weather forecasters for being wrong b/c in your job...you have control over the outcome. If you can't control the outcome....then you're incompetent.

Forecasters have no control over the outcome which is probably why you don't understand their job is 'weather prediction' and not 'weather production.'
