"snow squall" 1828, American English; earlier with a sense of "commotion, state of perturbed action" (1710), "a gust, a squall" (1690s); perhaps imitative, or else from 17c. flurr "to scatter, fly with a whirring noise," which is perhaps from Middle English flouren "to sprinkle, as with flour" (late 14c.).
