Totipotent: rain that could become any other type of rain

Just like some stem cells can become any other type of cell, this type of rain could become any other type of rain.

Of itself it hardly seems like rain. There are big drops but they are spaced wide apart. It is light enough to decide an umbrella is more bother than it's worth and to rely on the hoodie or scamper defences. In other lands you would think this rain is the precursor of a downpour, or maybe the tail end of one. But here it might go on like this all day, in which case it will probably become marathon rain (it has paced itself so it can last). Or it might go on like this all week in which case it will probably be relentless rain. Or it might go on all month in which case we will call it Seattle rain.

This recent post on RideBlog cheered me no end, there is a place as rainy as Glasgow.
