The weather forecast is accurate to the minute?

The weather forecast made by the meteorological department of any country is divided into equal ranges and grades. Looking at the actual timetable of railway transportation, we can know that the predicted arrival time in it is not that the driver cannot be required to control the speed to reach the arrival time within minutes, nor must it be accurate to minutes; It can be seen that the accurate arrival time of a gust of wind and a rainstorm cannot be accurate to "minutes", "seconds" or even "hours", which is a divisor for large-scale weather forecast in advance.

There is a joke: an old lady said to others, "People in some areas are really poor. Listening to the weather forecast every day, everyone says it will rain there. How can I stand it? " As we all know, "local area" only represents a part of a large area. In summer in the south, sometimes one road is raining and the other side is still under the scorching sun. Does this also require the meteorological department to make a forecast in advance, or hide across the road on time without an umbrella? I'm afraid no one feels it necessary to do so at present.

In fact, for forecasts with special requirements, small-scale and short-term weather forecasts can be predicted to about "minutes". This is not uncommon in space launch.
