inclement

What does "inclement" mean?
The word "inclement" is used to describe weather that is unpleasant, specifically cold, wet, or stormy. The mental image is of a sky that is "not merciful"—it is harsh, forbidding, and likely to ruin your plans for an outdoor picnic or a walk. It is a formal term, almost exclusively used in weather reports, official announcements, or professional correspondence. You would rarely use it in casual conversation; instead of saying "the weather is inclement," a friend would simply say "the weather is nasty" or "it's miserable outside."
