Meaning
A sign of trouble or difficulty that has not yet arrived but can be seen coming; a looming problem that threatens an otherwise good situation. Very often in the phrase 'the only cloud on the horizon' - the single drawback in an otherwise bright prospect. Usually negative in tone but mild - a warning of trouble, not trouble itself. Very often in the formula 'the only cloud on the horizon', naming the single drawback in an otherwise good outlook. Keep it distinct from this site's existing entries 'under a cloud' (suspicion resting on someone) and 'every cloud has a silver lining' (consolation). Regional use: All English-speaking countries.
Origin
The metaphor is transparent: a distant cloud is the first visible sign of an approaching storm. English has used clouds figuratively for trouble for seven centuries - Etymonline records the figurative sense, something that obscures or threatens, from about 1300, and the phrase under a cloud from about 1500 - but the horizon version is much younger. Google Books corpus data shows the exact phrase in printed use only sporadically from the 1790s, becoming continuous from the 1820s and peaking in the mid-Victorian decades; the favourite Victorian formula was 'the only cloud on the horizon', the single drawback in a bright prospect. The Free Dictionary's idiom guides gloss it as a sign of something unpleasant or unwelcome in the near future, and cite a classic-literature example in Jules Verne's Five Weeks in a Balloon, whose chapter title runs 'A Cloud on the Horizon'. No public dictionary prints a first-use date for the figurative sense.
