The weather forecast is becoming more and more inaccurate.

Weather forecast can be divided into immediate, daily, short-term, medium-term and long-term forecasts. Real-time forecasting is the most accurate, and the longer it takes, the more difficult it is to predict. Moreover, the forecast is in a certain range, and it is impossible to be accurate to a point.

As you said, accurate prediction of sub-regions can be achieved, but more energy and information are needed. Weather forecasters in the army, especially in military airports, can and must do it. There is no need for folk notice to be so accurate.
