The weather forecast shows rain, but it is the sun icon. What do you mean?

There are four possible situations: 1. Sunny to heavy rain; 2. sunny to heavy rain; 3. There is heavy rain between sunny days; 4. There is a rainstorm between sunny days! Because there are no more than two meteorological symbols in the weather forecast; Example: The symbol of moderate rain is added to the symbol of rain, some are moderate to heavy rain, and sometimes the forecast is moderate to heavy rain. Just watch the weather forecast and pay attention to the weather symbols. Anyway, different situations have different results!
