Change in the weather pattern
If weather changes rapidly, it is called change in the weather pattern. Often such a change is announced by a weather messenger. There a messengers which are meteorologically relevant, others are created by the vernacular: if the swallows fly high, the weather will become better, if they fly deep, the weather will become bad. Humans more or less feel a coming change in the weather pattern, too. And last but not least some peoples believe because of the afterglow, that in the next day the weather will be nice. But that does not happen always, because afterglow may occur as well with dry as with damp air, so that different weather is following.
