To indicate, suggest, or hint at something that is going to happen in the future; to be a sign or omen of what's to come.
From 'fore-' (before) + 'bespeak' (to indicate or suggest). 'Bespeak' comes from Old English 'bespæcan,' originally meaning to speak about in advance, now meaning to indicate or suggest.
When dark clouds forebespeak a storm, they're writing the future in the sky—natural signs that have guided farmers and sailors for thousands of years, long before weather apps existed.
