A sudden brief burst of activity, wind, or snow; or to move with sudden excitement or agitation.
Possibly from Norwegian 'flurra' (to hurry), or onomatopoetic. The word entered English around 1700s to describe quick, swirling motion.
A 'flurry' of snow sounds poetic, but meteorologically it means less than an inch of snow—weather terminology is surprisingly specific and technical underneath everyday language.
