The cloud is full of rain — appearances contain what they promise. What looks heavy with content delivers what it promises. Also used of people: the serious-looking, quiet person may have much more to offer than the bright, noisy one.
The agricultural communities of the Piedmontese plain and the Alpine foothills were expert readers of the sky. Before modern meteorology, the skill of reading clouds — their height, colour, texture, and movement — was an essential survival skill for the farmer who needed to bring in the harvest before the rain. The heavy grey cloud that rolled in from the Alps with its flat bottom and dark underbelly was indeed full of rain; the farmer who ignored it did so at his peril. The proverb extends this meteorological literacy into a broader observation about appearances: some things and some people look full of potential and actually are. It is the positive counterpart of the proverb about the empty appearance: not everything that looks promising delivers, but the cloud that looks full of rain usually is.
Piedmontese meteorological proverb extended into general observation. The skill of reading Alpine weather was essential in the agricultural communities of the Piedmontese plain.
