From Wiki:
A sunshower or sun shower is a meteorological phenomenon in which rain falls while the sun is shining. These conditions often lead to the appearance of a rainbow, if the sun is at a low enough angle. Although used in the United States, Canada, Australia, New Zealand, Ireland, and parts of Britain, the term "sunshower" is rarely found in dictionaries. Additionally, the phenomenon has a wide range of sometimes remarkably similar folkloric names in cultures around the world. A common theme is that of trickster animals, or the devil, getting married, although many variations of parts of this theme exist.
Meteorology
The nature of cumuluform clouds is such that the sun can often be seen while they are producing rain. If a sunshower occurs when the sun is low in the sky (specifically, any time the sun is at less than a 42° angle), a rainbow can occur.
Anecdotally, a sunshower is said to be a sign that rain will occur again soon, specifically that it will rain the next day.

Devils
In the United States, particularly the South, a sunshower is said to show that "the devil is beating his wife"; a regional variant from Tennessee is "the devil is kissing his wife".[4][5] In Canada, it's typically related to the devil beating his wife, then marrying numerous offspring; it is also said that he slaughters and rapes cattle, and then dances, which leads to rain.
In French, the phrase is "Le diable bat sa femme et marie sa fille" (i.e., "the devil is beating his wife and marrying his daughter"). In German, the variation is "Wenn's regnet und die Sonne scheint, so schlägt der Teufel seine Großmutter: er lacht und sie weint" (i.e., "When it's raining and the sun shines, the devil is beating his grandmother: he laughs and she cries").

A further variation is found in Catalan folklore, in a song: plou i fa sol, les bruixes es pentinen, plou i fa sol, les bruixes porten dol ("it rains and sun is shining, witches comb their hair, it rains and sun is shining, the witches are mourning").
