You predicted rain and it didn't rain (or vice versa)

Forecasting rainfall is one of the more difficult tasks of numerical models. Sometimes the forecast error is due to specific local phenomena (see the local cloudburst question) and sometimes, for example, to erroneous boundary conditions fed into our models. To determine the probability of precipitation, we recommend area maps (so-called detailed maps), which allow you to see whether, for example, you are in the middle of a large area with precipitation or on the edge of it.
